Subject: Keyport Wastewater Treatment Plant Efficiency

Survey.

On January 15, 1974, an efficiency study was conducted on the

Keyport Wastewater Treatment Plant.

Heavy rainfall during the previous week made flow measurementimpractical. The Weir designed for this purpose was over-flowing; consequently the volumes of water handled were wellbeyond the intended capacity of the plant.

All reductions - BOD, COD and solids — were negative. It isfelt that this condition was precipitated by two factors:

1) the large volumes of water entering the plant (dueto infiltrating rainwater) dilute the actual sewageand are responsible for the lower than normal BaD,COD and solids values.

2) the aeration tank is being over—aerated and nitri—fication has taken place. The resulting pinpointsolids are carried in suspension to the receivingwaters. This condition gives rise to high effluentBOD, COD and solids values.

In addition, no chlorination of the effluent took place. Thechlorinator was in a state of disrepair and apparently hadbeen in this condition for a number of weeks. The resultinghigh coliform counLs bring this deplorable situation intosharp focus.

The operator indicated that he devotes between 1/2 and 1hour per day to the plant. It is felt that this amount oftime is inadequate if the plant is to be run in an efficientmanner.

To: Larry Lewis

From: Allen Moore

Subject: Annapolis STP

On January 6 1975 an efficiency survey was conducted at the Annapolissewage treatment plant. The plant Is highly overloaded mostly duringthe wet season due to infiltration. The high overloading at the timeof the survey is directly reflected in the low reduction between In—fluent and effluent in all the pertinent parameters as shown in theattached STP Survey Report Form. The high fluctuations in pH areprobably due to effluents from a laundry and a car wash. I feel thatthe effluent is too highly chlorinated. The operator trys to maintainthe chlorine residual at 3 ppm. The flow was checked at the 900V-notch weir. The STP recorder showed 1.08 MGD and manual measurementshowed 1.01 MGD. The flow remained nearly constant probably due toeven, high infiltration. Historically, bypassing of the influentoccurred regularly with heavy rains. Recent installation of new pumpsnow runs all sewage through the STP.
