Inlet Structure For Clarifiers
US Patent:
7243802, Jul 17, 2007
Filed:
May 13, 2004
Appl. No.:
10/844697
Inventors:
Orris E. Albertson - LaBarge WY, US
Assignee:
Enviro Enterprises, Inc. - LaBarge WY
International Classification:
B01D 21/24
US Classification:
210519, 210528
Abstract:
A clarifier is provided with an improved inlet structure which receives influent from influent column ports and discharges the influent uniformly around the entire circumference of the inlet structure. The influent column ports may be baffled. Angled guide vanes on the inlet structure reduce the flow energy and effect a tangential flow into a feedwell in the basin. The feedwell may be conical to further reduce the velocities and create an outward flow to counteract inward flows in the basin.
Aerated Grit Chamber And Method
US Patent:
6921489, Jul 26, 2005
Filed:
Jul 19, 2002
Appl. No.:
10/199868
Inventors:
Orris E. Albertson - LaBarge WY, US
International Classification:
B01D021/00
US Classification:
210802
Abstract:
An aerated grit chamber includes an aeration zone in which influent is vigorously aerated and a settling zone separated from the aeration zone by a baffle beneath which wastewater flows from the aeration zone into the settling zone. The aeration causes swirling motion and causes larger grit particles to settle and accumulate in a grit trough on the floor. An inclined plate settler in the upper part of the settling zone causes smaller grit to settle and fall into the grit trough. In order to prevent overly efficient operation at low flow rates and settling of organics with the grit, internal recycling of the wastewater from the settling zone back into the aeration zone is effected, preferably with air lift to induce recycling but also using alternative techniques such as direct pumping.
