Laundry wash water recycle system comprising a repressurization pump in fluid communication with a storage tank containing previously used wash water for pumping the used wash water sequentially through a lint filter, a cyclone, and a multi-media filter disposed in sequential series wherein the self-cleaning lint filter in sequential series combination with the cyclone removes insoluble solids with the multi-media filter providing a final filtration for obtaining an output of pressurized double filtered cyclonically processed water. An advanced oxidation combination is introduced into pressurized double filtered cyclonically processed water and mixing occurs for producing a double filtered cyclonically processed advanced oxidation treated water that is communicated to a clean water storage tank for providing on demand delivery to at least one washer and continuous delivery of a feedback flow to the inlet storage tank for providing constant recirculation of treated water through the system.

Disclosed herein are methods and systems for treating greywater from a microbial food decomposition process. A method includes flowing, into a mixing chamber of a water treatment tank, a first volume of untreated greywater. A second volume of recirculated greywater mixed with ozone gas is flowed into the mixing chamber, and mixes with the first volume of untreated greywater to produce a third volume. The third volume of greywater is flowed into a storage tank. The method further includes diverting a first portion of the third volume out of the water treatment tank, and diverting a second portion of the third volume into a recirculation line that flows the second portion back to the mixing chamber.

The invention relates to a method and system for recycling domestic greywater. Greywater is drawn from a greywater waste pipe through an overflow pipe of a sanitary fixture, thereby, permitting greywater to be collected for reuse without the need for complicated and expensive retrofitting and/or reconfiguration of existing plumbing infrastructure. The system and method of the present invention can easily operate independently or be integrated with domestic utility systems to supply these utility systems with greywater.

The present invention provides a new approach to decreasing water use, energy consumption, chemical use and sewage expense in commercial kitchen operations by reusing drain water and recovering the heat energy, thereby reducing operation costs. The invention, however, is not limited to kitchen operations, it could be applied to other operations that produce greywater and could benefit from reusing water and resources.
