Abstract: The present disclosure is directed to a treatment system in a lagoon containing water that promotes the formation of biologically active granules that digest sludge in the lagoon, the lagoon comprising a bottom thereof, the water of the lagoon having a surface layer, the system including X number of water circulators in a cluster having an impeller disposed in the lagoon, wherein X is greater than or equal to three and hydraulic walls formed from at least some of the water expelled from each of a given pair of adjacent water circulators, wherein each of the hydraulic walls intersects at the midpoint of any two adjacent circulators, said hydraulic wall redirecting the expelled water downward towards the bottom of the lagoon, wherein the hydraulic walls at least partially surround at least one circulator.

Abstract: In one embodiment, hydrodynamic cavitation lyses influent bacteria, releasing intracellular enzymes, and creates CaCO3 seed crystals that are discharged at the base of the water column. Bottom-dwelling upflow anaerobic sludge blanket (UASB)-like granules grow in a dense, viscous N, P & Ca++ rich fluid (“hydrolytic brine”). The brine hydrolyzes ancient sludge and fresh solids into simple liquids. The granules convert hydrolyzed liquids into gas. New CaCO3 seeds grow at the produced gas/supernatant interface and propagate across the entire lagoon. Once the sludge inventory is digested, there is an excess of granules that modulate their gross productivity in response to substrate load, pH, and temperature. In one specific example, the treated lagoon has no odor, is free of gelled sludge and effluent.

Abstract: In one embodiment, a method of reducing at least one of nitrogen, carbon and phosphorous in a lagoon that includes at least three cells.
