Abstract: A process water treatment and recycling system clarifies and purifies the process water in a food processing or similar system wherein the treated water may used in the fresh water stream of the system. Removal of useful byproducts in the process water stream is also facilitated. The system is a mechanical filter system and does not use any chemicals. The system is a multiple step filter process. Additional steps may added where further clarification is required and fewer steps are contemplated in certain applications. The system incorporates multiple mechanical screening to remove the solid waste from the water stream. Experimental result have established that up to 100% of TSS, 100% of BOD and 86% of COD are removed. This brings the water to acceptable recycling purity ranges and reduces the amount of fresh water required to be added to the system by as much as 50%. It also increases the recovery level of useful byproducts such as starch.

Abstract: A liquid solid separation apparatus having a porous metal pipe sealed inside a non-porous metal pipe which allows a portion of the liquids, e.g., hydrocarbons and water to pass through the first pipe into the non porous pipe from which they are removed while solids are retained within the porous pipe. In the process there is a system pressure which aids in the filtration and a circulating velocity which removes the detained solids. Preferably a portion of these solids with reduced liquid content are recycled back to the system, mixed with fresh feed. By recycling a porion of the recovered solid concentrate the velocity of the flow in the system kept constant and the system itself is stabilized.

Abstract: This disclosure sets out a method and apparatus for recovery of cesium formate in water solution after use in a drilling process where trash and other debris accumulate in the drilling fluid. It incorporates a first stage centrifuge, a second stage centrifuge and a membrane separator serially connected, and incorporates a feedback loop. A feedback loop iteratively redirects solids and heavy weight concentrate after processing and recycles it to enhance recovery by enhanced removal of cuttings and trash in the stream. In addition, cuttings and other solids removed from the fluid stream are introduced into a wash tank, mixed with water, and the cuttings are further processed to remove remnants of the cesium formate. These recovered cesium formate remnants are passed through an evaporator to regain the density loss attributable to the dilutive wash water. The cuttings can then be thrown away without throwing away the valuable cesium formate in the drilling solution.

Abstract: A process and system for waste water treatment including a concentration means positioned at the front of the treatment system in order to concentrate the starches and sugars contained in a waste stream. In a mixing vessel, the concentrate stream is treated with a variety of additives in order to increase consumption of the biological components and to produce a stream having a predictable and predetermined level of soluble starches. The waste stream is solubilized by subjecting the stream to heat and enzyme treatment such that the starches and complex sugars are converted to simple sugars. In a fermentation vessel, a carefully selected yeast strain is introduced into the waste stream and permitted to feed on the sugars. The operating conditions in the vessel (e.g. pH, temperature, oxygen supply, and mineral supply) are carefully controlled to enhance consumption of the biological components in the waste stream.

Abstract: A food starch seperator comprising a serially connected centrifuge and a membrane seperator further comprising a sintered pipe providing pore flow paths including a pumped source of food plant liquor, outputs for the centrifuge and membrane seperator and a control system to regulate the flow of the food plant liquor.
