Continuous filtration systems using pump, venturi and flow control valve
First Claim
1. A valve comprising a valve body, said valve body comprising:
- (a) a feedstock conduit;
(b) a venturi flow conduit in contact at an intersection with said feedstock conduit, and adapted to suck feedstock fluid through said feedstock conduit, the force of said sucking dependent upon flow through said venturi flow conduit;
(c) a bypass flow conduit adapted to conduct bypass fluid through said valve; and
(d) an adjustable first flow controller to control flow of said bypass fluid.

Abstract
Continuous filtration systems comprising a venturi, flow control valves, filter and pump. In one specific embodiment the flow control valve and venturi are combined hereinafter referred to as a CHUF. The CHUF may also contain concentrate release, and temperature, flow and two pressure sensors into a single structure. A continuous filtration system for liquid or gas applications is constructed by plumbing a CHUF to a pump and filter. The CHUF is constructed of plastic, stainless steel or other materials. Different plumbing to the CHUF positions the filter in either series, parallel, or series and parallel with a venturi and flow control valve resulting in different pressures and flows at the filter. A single flow control valve simultaneously controls inflow and outflow of the filtration system. Additional flow control valves are used in a process to control pressure independent of flow at the filter.
