The mechanical bar screen is a self-cleaning device that utilizes a continuous moving belt to remove solids from the influent waste stream. Under flow from the screen will flow by gravity to a series of two 3.1 million gallon partial mix aerated lagoons. The partial mix aerated lagoons and effluent storage lagoons are earthen lagoons with common wall berms. A natural clay liner is provided in the lagoons to prevent leakage and underground contamination. Here, natural microorganisms break down the organic matter.
Settable solids fall to the bottom of the lagoon and undergo anaerobic decomposition.
Effluent from the partial mixed aerated lagoons is disinfected by the addition of sodium hypochlorite and detention in a contact tank. After exiting the contact tank the disinfected effluent can be either stored in the effluent storage lagoon or pumped to the land application system. The land application system utilizes a buried solid set sprinkler system to simulate rainfall. A buried solid set sprinkler system contains a series of buried mains and laterals for the distribution of the effluent. The visible portion of the land application system consists of riser pipes with sprinkler heads for the dispersion of the effluent.
