Wastewater Concentrator Method and System

Номер: US20130075329A1
Автор: Culler Paul L.
Принадлежит: Ecolivegreen Corp.

Disclosed is a system for reducing the demand of wastewater volume flowing through a wastewater collection piping system thereby increasing the effective capacity of the system. A portion of the wastewater is diverted from a sewer main. The solids are separated from the liquid; for example, by a centrifugal separator such as a vortex or cyclone separator. The recovered liquid can be treated and made available for reuse or disposed of. The separated or concentrated solids are reintroduced into the sewer main dynamically in a portion that adjusts the wastewater loading, or alternatively, the solids loading, in the sewer main to a predetermined amount or predetermined range. The system can be adapted to reducing demand of wastewater volume flowing within a wastewater treatment plant by diverting the wastewater in the flow path between the wastewater plant inlet and the biological processing stage and reintroducing separated solids downstream. 1. A method for processing wastewater within a wastewater treatment plant comprising:diverting a portion of wastewater flowing through the wastewater treatment plant between a treatment plant inlet and a biological treatment stage;separating solids in the diverted wastewater from liquid therein;reintroducing the solids before the biological treatment stage while not reintroducing at least a substantial portion of the liquid; anddynamically jointly adjusting:a) a rate at which the solids are reintroduced; andb) a rate at which wastewater is diverted, the dynamically jointly adjusting being carried out in such a way that a quantity of wastewater flowing into the biological treatment stage per unit time downstream of the diverting is adjusted to be no more than a preset quantity.2. The method of wherein the rate at which the solids are reintroduced is dynamically adjusted such as to keep a quantity of solids per unit volume flowing into the biological treatment stage to be no more than a preset quantity.3.

APPARATUS AND METHOD FOR OPTIMIZING HYDRO-CYCLONE SEPARATION IN A FILTERING SYSTEM

Принадлежит: Velocity Water Works LLC

An apparatus and method for optimizing hydro-cyclone separation in a filtering system is disclosed. The apparatus includes a first, second and third storage tanks, a pump, a motor, a variable speed drive, and a hydro-cyclone. The pump pulls fluid from the third storage tank and routes it to the hydro-cyclone where particles are separated out. The filtered fluid is then routed onto a mechanism, such as a car wash, where the clean fluid is utilized. Since the car wash cannot always use all of the filtered fluid, a controller monitor flow rate and fluid pressure, and operates a proportional fluid control valve to bypass some or all of the fluid routed to the car wash and redirect it back to the second storage tank. This process allows the hydro-cyclone to operate at maximum efficiency while flow to the carwash may vary. The dirty particles separated out by the hydro-cyclone are routed to the first storage tank. 1. An apparatus for optimizing hydro-cyclone separation in a filtering system , comprising:a) a first storage tank, a second storage tank and a third storage tank sequentially fluidly connected;b) a pump driven by a motor having a variable speed drive, said pump having an inlet and an outlet;c) a first fluid line connecting said third storage tank to said inlet of said pump;d) a hydro-cyclone having an inlet port, a first outlet port and a second outlet port, said hydro-cyclone being positioned downstream of said pump;e) a second fluid line connecting said outlet of said pump to said inlet port of said hydro-cyclone;f) a first pressure transducer positioned across said second fluid line for measuring pump pressure;g) a third fluid line connecting said first outlet port of said hydro-cyclone to a mechanism dispensing filtered fluid;h) a flow transducer positioned across said third fluid line for measuring fluid flow;i) a second pressure transducer positioned across said third fluid line downstream of said flow transducer for measuring output pressure;j) a fourth ...
