Description:
The general objective of this study was to determine the yearly performance of a seven cell facultative wastewater lagoon system and to compare this performance with existing state and federal discharge standards and with the criteria used to design the lagoon system and to evaluate existing design equations. Twenty-four hour composite samples or grab samples for certain analyses were collected for four 30 consecutive day periods (once each season) and twice a week in the periods between for 13 months and tested for chemical and physical parameters. Samples were taken from the influent at the end of each cell, and from the final effluent. The data of tests for total and soluble BOD5, COD, suspended solids, nitrogen forms, total phosphorus, total algal count by genera, fecal coliform bacteria, fecal streptococci bacteria and total coliform bacteria, influent and effluent daily flow rates, air temperature, wind, evaporation, and solar radiation are reported with a discussion of the results in relation to the discharge standards and design of lagoon systems.
