Facultative ponds work great in theory and often in practice. But due to the vagaries of nature, and because populations and industrial use can grow beyond prior estimates, these ponds often need some help. The SolarBee can correct problems of overloading, odors, algae blooms, duckweed(in many cases), high BOD, high suspended solids (TSS), high ammonia (N), high phosphorus (P), high pH, low DO, and excessive volatile sludge buildup.
