A full scale wastewater treatment system consisting of a novel extended aeration unit and intermittent sand filter was demonstrated. The treatment system was designed to meet the special needs of small plants and to meet future industrial discharge limitations. With a hydraulic loading rate of 0.36 mgad and a sand source having an effective diameter of 0.35 mm and a uniformity coefficient of 2.5, a filter run of 109 days was observed. The average BOD5 and TSS of the filter effluent was 10.4 mg/l and 11.1 mg/l, respectively. The cost of construction and operation of the treatment facility is presented. The study revealed an installation cost of $1.40/gpd capacity and a treatment cost of $0.29/lb BOD5 applied. Information needed to select, design, and construct an intermittent sand filter is also presented. The project evaluated the most economical means of meeting the NPDES monitoring requirements. The conclusion was that the small packinghouse managers should use a commercial laboratory when monthly or quarterly analyses are specified.
