Abstract (en)
[origin: WO9965829A1] A four-pond wastewater treatment process for controlling algae and ammonia in the effluent stream is disclosed. A plurality of opaque modular cover casings (80, 81, 82, 83) are floated on some or all of the surface of the aeration pond, sedimentation pond, and polishing pond to block sunlight and thereby control algae growth and suspended solids. Attached growth biomedia is submerged in the aeration pond to enhance nitrification of ammonia.
