Filed:

Mar 20, 2003

Appl. No.:

10/393171

Inventors:

Patrick Hanlon - Sunman IN, US

International Classification:

B01D021/02

US Classification:

210/524000, 210/528000

Abstract:

Described herein is an improved method for removing settled solids from a clarifier tank. The process is performed by utilizing an open pipe for an airlift pump that extends from the top to the bottom of the tank; the said airlift pipe also acts as the drive shaft, support and attachment to the scrapper mechanism which rotates at the bottom of the tank and moves the settled solids toward the center drawoff well; the said drive shaft/airlift pump into which air is introduced to transport the liquid and solids at the bottom up to the discharge; said pump extends through the mechanical drive mechanism presenting an unimpeded path for the liquid flow up through the drive and out the top into a discharge trough to be directed away or recycled; the said mechanical drive imparts a turning moment onto the drive shaft/airlift pump to rotate the scrapper; the same drive mechanism is so configured to incorporate the drive shaft/airlift pump to allow the unimpeded flow path through it; therein the improvement is utilizing a multifunctional drive shaft/airlift pump configured to be incorporated into and driven by the mechanical drive mechanism for scrapping the settled solids at the bottom of the tank, using an airlift pump mechanism for removal of these settled solids in a way that simplifies, enhances and remedies problems of pumping the settled solids from a clarifier.

Abstract:

An submersible media-filled wastewater treatment filter () for use with a septic tank () or other treatment unit utilizes a special media () to provide solids separation and biological treatment within the filter unit. The media is a highly compressible material with a large surface area to volume ratio. As microorganisms that provide biological treatment of the wastewater flowing therethough grow and multiply in the filter media, the pores of the media may become clogged with biomass and require flushing. The filter provides for in place regeneration of the media. For example, a tool () can be used from above the ground surface to compress the media (), thus flushing the accumulated solids out of the filter media and into the tank () in which it is installed.

International Classification:

B01D 2108

US Classification:

210197

Abstract:

Described herein is an improved water treatment process for separating particulate contaminants from raw water. The process is performed by introducing, into a single tank, raw water injected with a coagulating agent for neutralizing charges on the particles and a flocculating agent for agglomerating the neutralized particles; mixing, in the mixing area of said tank, the neutralized and agglomerated particles with a granular medium to increase the size and weight of the particles; directing the particles and water from the mixing area of said tank to a baffled quiescent zone for settling; further directing said water, free of settlement, in said quiescent zone through a buoyant medium to entrap unsettled particles; and wherein the improvement is characterized by conducting tapered flocculation in the mixing area of said tank with a turbine mixer having a plurality of radial blades of varying surface areas, said blades tapered in decreasing areas as the distance from the point of influent increases.
