Book excerpt: "Two basic extended-aeration plants that discharge effluents to intermittent watercourses were studies during various seasons of the year. Except for periods of slug discharges, the plants produced effluents with a BOD of less than 35 mg/l and suspended solids less than 30 mg/l. Plant efficiency was directly related to the amount of solids lost as a result of fluctuations in raw waste flow or as a result of denitrification and rising soldis in the sedimentation basin and consequent overflow. With the addition of sludge-wasting facilities or effluent-polishing units, these plants would be capable of efficient continuous operation for long periods. Periodic heavy discharge of suspended solids formed sludge deposits in the two streams receiving effluent from the plants. Counts of benthic forms above and below the plant outfalls and at sampling points downstream clearly showed the effect of these deposits. Algal growths were profuse in unshaded portions of the streams, indicating high nutrient levels."--P.v.
