ANNUAL (FOURTH QUARTERLY) PROGRESS REPORT
March, 1980 through March, 1981
EPA Project No. CR807299-01-l
DWR Agreement No. B-53459 AM I
GENERAL
This, the Annual Report for the project "Artificial Wetlands as a Means of
Advanced Biological Wastewater Treatment," will both detail the work com-
pleted during the period January through March, 1981 (Fourth Quarterly
Report) and also summarize the progress made in the first full year of the
project which began in March of 1980. Previous quarterly reports have out-
lined the exceptional utility of the artificial marshes for the removal of
nitrogen from secondary wastewater effluents. Using methanol as the ex-
ogenous source of carbon to drive denitrification, removals of 99% of total
inorganic nitrogen and 97% of total nitrogen were demonstrated at application
rates as high as 19.8 inches per day. Studies in the autumn (October -
December)of 1980 (Third Quarterly Report) have shown that the artificial
marshes, amended with mulched plant biomass as the source of exogenous car-
bon, could remove 90% of the total inorganic nitrogen and greater than 83%
of the total nitrogen in the inflowing wastewaters at application rates of
up to 9 inches per day.
The present report will describe our studies during the winter of 1981
(January - March). Throughout this period, both methanol and plant mulch
amendments continued in the artificial wetlands with positive results. It
was noted, however, that due to lowered water temperatures (12-14'C) in the
winter, nitrogen removal rates in the mulch-amended plots were no higher
than 63% for total inorganic nitrogen and 55% for total nitrogen, at an
application rate of 6.6 inches per day. At a lower application rate of 3.3
inches per day, the removal rates were much higher, 91% for total inorganic
nitrogen and 84% for total nitrogen. This data indicates that design of
_- 2. r . *
operational wetland treatment systems must take into account the decreased
removal efficiencies during winter when estimating the land acreage required
per unit volume of wastewater to be treated. On the other hand, our inves-
tigations well demonstrate that even during winter both higher application
rates and removal efficiencies of greater than 95% of total nitrogen can be
attained by supplemental methanol addition to the marsh beds.
This report will be divided into nine sections:
1. Nitrogen Removal
2. Harvestable Yield of Vegetation
3. Carbon and Nitrogen Analyses of Wetland Vegetation
4. Evapotranspiration Measurements
5. Removal of Coliform Bacteria
6. Work to be Accomplished During Next Quarter - Phase I
7. Work to be Accomplished During Next Quarter in Demonstration-Scale
Artificial Wetlands - Phase II
8. Annual Summary of Work Completed
9. Financial Status
Section 1. NITROGEN REMOVAL
Since October 15, 1980, selected marsh bedshave been receiving applications
of mulched plant biomass to satisfy the carbon demand of denitrification
(35 - 50 lbs dry wt per week per plot). During the period from October
18 through December 23, 1980, nitrogen removal efficiencies for all mulched
plots were 90% for total inorganic nitrogen and just over 83% for total ni-
trogen (TEN + NO3 + N02) at application rates of up to 9 inches per day.
Table 1 shows the nitrogen removal efficiencies for marsh beds receiving
mulch amendments from December 30 - March 23, 1980-81. During this winter
period, marsh plots demonstrated mean nitrogen removal efficiencies of 63%
for total inorganic nitrogen and 55% for total nitrogen; when wastewaters
3.
were applied at an application rate of 6.6 inches per day. Table 2 shows
that,when the application rate was reduced to 3.3 inches per day, removal
rates were much higher, mean values of 91% for total inorganic nitrogen and
84% for total nitrogen. In plots amended with methanol (Table 3), removal
efficiencies were very high, a mean of 97% for total inorganic nitrogen and
95% for total nitrogen, even at the higher application rate of 6.6 inches per
day. This data seems to indicate that lowered winter water temperatures do
not so markedly alter the activity of the denitrifying bacteria, as much as
decrease the activity of the plant mulch (cellulose) decomposers, which by
their very action make carbon substrates available to the denitrifiers.
Section 2. HARVESTABLE YIELD OF VEGETATION
During this quarter, 6 - 8 months after rhizome transplantation, the density
of the aquatic plants in the artificial wetland beds has increased so that
maximum vegetative cover has by now been established. This means that future
yields of biomass should represent stable and realistic measures of what we
can expect in a mature wetlands system.
In the Third Quarterly Report we detailed how the measured growth rate of
n cattails exceeded 9 gm dry wt per mL per day in the artificial wetlands
during the period from September 26 through November 25, 1980. This quarter
we can report a rate of growth for bulrushes during winter that is even
higher, 10.2 gm dry wt per m2 per day.
On January 22, 1981 and again on March 20, 1981, a 3m x 3.5m quadrat in the
center of plot 2W (bulrushes) was harvested (12-18" above ground) and the
yield (dry wt) determined. On March 20 the quadrat contained a harvestable
biomass of 9.7 lbs wet wt per m2 or 1.32 lbs dry wt per m2 (13.6% dry
wt : wet wt). This amounted to a production rate of 5,342 lbs dry wt per
acre over the 58 day period, or a growth rate of 10.17 gms dry wt per m2
per day. If this rate of productivity was sustained for a complete year,
yields would be 33,618 lbs per acre per year, solely for harvestable above-
ground biomass. Winter biomass yields from established stands of marsh
vegetation as high as these values presented above are most encouraging in
that they indicate that when the summer growing season is taken into account
the annual biomass yields will be prodigious.
Section 3. CARBON AM) NITROGEN ANALYSES OF WETLANB VEGETATION
In order to better quantitate productivity of marsh plants in terms of the
amount of carbon fixed per unit area of wetland, and in order to obtain a
direct measure of the amount of nitrogen removed from the system by the
plants, we measured the carbon and nitrogen content of the dried aquatic
plants, using a Carlo-Erba CN analyzer. This unit combusts the carbon to
CO2 and the nitrogen to NO2 (subsequently reduced to N2) and these gases are
then separated in a chromatographic column and their amounts measured by a
thermal conductivity detector.
Table 4 presents values for percent composition of carbon and nitrogen in the
shoots of both cattails and bulrushes harvested in October and November of
1980. The mean carbon content of dry plant matter is 39% f1.7 for the bul-
rushes and 40% 2 2 for the cattails. In the case of nitrogen content, Table
4 shows that the mean value for both species of plant is just over one
percent of the dry wt (1.05 2 0.41 for bulrushes, 1.06 t 0.43 for cattails).
The high resultant C:N ratios ( M 4O:l) for these plants indicates that
harvested biomass makes an ideal mulch amendment, these additions providing
more carbon substrates (to supply denitrifiers) relative to nitrogen; the
latter is especially undesirable when the aim is maximum nitrogen removal.
Using the above value of 1% as the nitrogen percent composition of dry plant
5.
biomass, and knowing the yield of harvested biomass per unit area of wet-
land (Section 2), we can estimate the amount of nitrogen that can be removed
by plant harvest, as compared to the amount that flows into the wetland during
a given period. A productivity of 10.2 gm dry wt per m2 per day of plant
biomass would require a nitrogen uptake corresponding to 1% of this value,
or 0.1 gm day per m2 of marsh. Since one marsh bed is approximately 66 m2,
then the total plant uptake of nitrogen would be about 6.6 gm per day per bed.
At the lowest application rate we have tested (3.3 inches per day) 5,451
liters of wastewater flow into a single marsh bed per day. Assuming a
mean nitrate content of 15 mg/l in the inflowing water, then 81 gms per day
of N03-N will enter the marsh bed.
Clearly, winter productivity levels (involving incorporation of 6.6 gm per
day per plot) and subsequent plant harvest could account for only a small
fraction of the total nitrogen removal we have observed in mulched or methanol
amended plots.
Section 4. EVAPOTRANSPIRATION RATES
Assuming a mostly constant water level over a moderately long time interval,
the evapotranspiration (ET) rate may be calculated as the difference between
total inflow volume and the total outflow volume. This was computed (Table
5) for the period from November through December or January for seven vege-
tated plots (both cattails and bulrushes). It can be seen that ET losses
amounted to a mean value of 10.6% (s,d.= 7.9) of the influent wastewater
volume. This value can be compared to a mean ET loss of 16% (s.d.= 8.1)
calculated for vegetated plots during the early fall period (September -
October) of 1980 when solar radiation and air temperatures are significantly
higher (Second Quarterly Report).
Cumulative flow data will be collected throughout the spring and summer of
- 6. .
1981 in order to facilitate the accurate determination of the seasonal ET
factor for these artificial wetlands.
Section 5. REMOVAL OF COLIFORM BACTERIA
In order to get some idea of how the artificial wetlands function with regard
to the removal of total coliform bacteria, in January of 1981 we initiated a
monitoring program in selected plots to ascertain removal efficiencies. Table
6 presents a compilation of these data. It can be seen from the table that
mean removal efficiencies are 90% (s.d. = 6.0) in the tested plots, all
having residence times between 30 - 60 hours (application rates 3.3 - 6.6
inches per day). Although significant numbers of coliform bacteria do remain
in the effluent from the marsh beds, the marked reductions that were demon-
strated point to the potential usefulness of these wetlands in removing a
majority of disease-causing organisms present in unchlorinated secondary
wastewaters.
Section 6. WORK TO BE ACCOMPLISHED DURING NEXT QUARTER - PHASE I
In the next quarter work will continue with a similar focus to that of the
past quarter (January - March, 1981). Interest will center upon the follow-
ing:
1.
2.
3.
Long-term treatment efficiency of mulched plots with regard to nitrogen
removal, as well as removal of BOD, suspended solids and phosphorus.
Particular attention will be paid to the highest application rates and
associated removal efficiencies that can be sustained during the spring
and early summer.
Measurements of harvestable yield (and standing biomass) of marsh vege-
tation during the spring season.
Testing a combination of sequential mulch and methanol additions to two
marsh beds plumbed in series in order to determine if the residual
7.
nitrogen remaining in the effluent of the first (mulched) plot can be
removed from the second plot with small, measured additions of methanol.
Such a system was set up in plots 5W and 6W in March, 1981 and is now
being carefully evaluated.
Determination of optimal flow regimes and flooding patterns and the role
of higher plants in denitrification (as compared to unplanted control
plots). These studies are of a continuing nature and will be reported on
in detail once we have completed a careful analysis of seasonal patterns.
Section 7. WORK TO BE ACCOMPLISHED DURING NEXT QUARTER IN DEMONSTRATION-
SCALE ARTIFICIAL WETLANDS - PHASE II
The primary objective of this, the second phase of the artificial wetlands
project, is to demonstrate that a one acre wetland, designed and operated ac-
cording to information acquired in the pilot skale experimentation, can remove
nutrients (primarily nitrogen), BOD, and suspended solids from secondary ef-
fluent with high efficiency and with relatively low capital and operating
expense.
Plans currently call for the treatment of between 90,000 - 270,000 gallons
per day (application rates of 3.3 and 9.9 inches per day, respectively),
using plant mulch as the principal source of exogenous carbon to drive de-
nitrification. The results of the pilot-scale project have been extremely
encouraging, and have allowed us to select the most cost effective and
biologically efficient combination of parameters (e.g., application rates,
flooding regime, exogenous carbon source, mulching schedule) for use in the
demonstration-scale wetlands.
Excavation of the one acre wetlands site has already been completed. Most
of the trenching and major plumbing will be finished by April 1, 1981.
Present plans call for both the plastic liner and the gravel substrate to
8. . .
be in place by early May and for planting to begin in mid-May. Both Scirpus
(bulrushes) and Typha (cattails) will be propagated by rhizome transplant
from natural stands locally available, each covering about 0.5 acre of the
artificial wetland.
Specifically, the experimental work plan for Phase II of the artificial wet-
lands project will address the following:
1. Determine the design and operational parameters of a one acre artificial
wetland that will maximize nitrogen removal processes using plant biomass
(mulched and applied to the surface of the marsh) as carbon supply for
denitrification.
2. Determine the effect of extended operation on treatment efficiency with
special emphasis on seasonal variations, and any changes in effluent
quality due to clogging by refractory particulate matter with subsequent
bleedthrough of suspended solids and associated particulate N and P.
3. Evaluate the effect of flooding and drying cycles to prevent clogging,
increase decomposition of added mulch, and prevent insect and odor
problems.
4. Continue to evaluate the role of marsh plants in nutrient removal, and
their interaction with the bacterial community to stimulate denitrifica-
tion.
5. Measure the harvestable yield of the vegetation in order to calculate
the amount of carbon fixed per unit surface area. This amount of carbon
fixed endogenously by the artificial wetlands is potentially recyclable
to satisfy the carbon demand of denitrification and is an important
factor under intensive evaluation.
6. Determine the flow patterns and retention time of the large-scale wet-
lands by performing Rhodamine WI dye tracer studies.

Section 8. ANNUAL smmw OF wow COMPLETED F-ROM MARCH 17, 1980
TO MARCH 23, 1981
The four quarterly progress reports thus far submitted present in detail the
work done since the outset of the project. We have well demonstrated that
the artificial wetlands can function very efficiently as a biological system
for the advanced treatment of wastewater effluents. Some of our findings
are listed below:
1. The emergent aquatic plants Typha (cattails), Scirpus (bulrush), and
Phragmites (reed) can be vegetatively propagated by rhizome cuttings.
The transplants , particularly the cattails and the bulrushes, grow well
in gravel flooded with secondary municipal wastewater effluent, with
propagation efficiencies of nearly 100% and over 75%, respectively.
2. With methanol added as an exogenous carbon source, the artificial wet-
lands can bring about the removal of nearly 99% of the influent total
inorganic nitrogen, and greater than 97% of the total N in the inflowing
waters, at application rates as high as 19.8 inches per day. In winter,
treatment efficiencies with methanol are slightly (2%) lower for appli-
cation rates of up to 6.6 inches per day.
3. At application rates of between 3.3 - 9.8 inches per day (depending upon
the season) , plant biomass (mulched and applied to the surface of the
marsh beds) may serve as an alternate source of carbon to drive denitri-
fication. Under these conditions the marsh beds can remove about 90%
of the inflowing total inorganic nitrogen and 83% of the total nitrogen,
with minimal expense incurred for carbon supply.
4. The artificial wetlands also function well to remove greater than 80%
of the influent BOD and suspended solids, and about 90% of the total
coliform bacteria; however, phosphorus removal is not significant
(C25%) at current retention times.
- 10. .a
5. Marsh plant productivities during both autumn and winter have been very
high, 9-10 gms dry wt per m2 day. At these rates, harvestable yields
for both cattails and bulrushes will be greater than 30,000 lbs dry wt
per acre per year for aboveground biomass. This data indicates that
when higher summer growth rates are taken into account the annual yields
will be even greater. The harvested biomass can be directly recycled to
provide more than 50% of that needed to drive denitrification. If
belowground biomass can also be harvested, then the total carbon demand
of denitrification in the wetlands can be satisfied by endogenous pro-
duction.
6. Evapotranspiration loss rates of water from vegetated plots are in the
range of 16% t 8 during the fall season (September - October) and
10.6% 'r 7 during the winter (November - January). This fact indicates
that nutrient removal efficiencies are actually better than effluent
concentrations would indicate.

MEMORANDUM
TO: City Manager
FROM: Director of Utilities
SUBJECT: Information on San Diego Reclamation Agency
This is in response to your inquiries relating to the San Diego Region
Water Reclamation Agency.
The City joined with other agencies in 1977 under a joint powers agreement
for the following purposes:
1. To jointly study the methods and technology of water
reclamation, water management and the reuse of wastewater ;
2. To establish one or more centers for the conduct of
such studies ;
3. To experiment, test and apply, in an operational setting,
advanced techniques for the reclmation and reuse of water;
and
4. To develop water reclamation plans and programs that may be
adopted by the parties hereto for use and application within
their respective jurisdictions.
Basically, the purpose of the organization was to perform applied research of
processes relating to sewage effluent. They utilize the facilities of the
old EPA project at Padre Dam -- Bert Elkins is the Manager of the organization.
Assessments are made to member agencies on the basis of $l,OOO/year plus $100 per 100,000 gallons of rated flow (or $5,400 for Carlsbad) -- new sewage
agencies pay a flat fee of $1,500. Organizationally, there are two groups:
1. Board of Directors -- an elected official of each member
agency -- Mr. Anear
2. Management Committee -- an appointed member from each
agency to provide technical review of RFP's, contracts,
etc. -- Les Evans/Ron Beckman
The agency has received grant funding of several projects -- currently a
wetlands project using aqua culture in open ponds is being run. Bert Elkins is presently attempting to get funding for what is known as a CCBA
(Coordinate Chemical Binding Absorption) process. This latter project
Page 2 - Information on San Diego Reclamation Agency
converts sludge to a lightweight aggregate which has the potential of
being a cost effective method of disposal.
I have attached a list of member agencies, the FY 81-82 budget and the
last quarterly report. Mr. Anear regularly attends the Board meetings
and can provide a more objective appraisal of the effectiveness of the
organization. Funds for this membership were included in this year's budget (Acct. 1-135). Also included is an agenda bill for payment should you think it desirable to have Council give authorization.
