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. The mechanical filtration system of the subject invention eliminates the need for various chemicals, defoamers and process water treatment chemicals. No additional process water treatment is required for water released into the public waste water system.
