Key issues in laundry waste water are lint,residual chemicals and temperature.A collection tank could help in lowering the temperature to an extend.Lint removal with units like vibratory screen is necessary.Use of coagulants need to be limited ,since TDS is a key issue in the laundry water for quality of wash .Probably sand ,carbon and micro filtration will ensure reasonable quality for partial recycle .100% recycle has been a challenge and the presence of cationic chemicals in the wash composition does impact RO membranes performance and life.These observations are based on my personal experience with laundry waste water recycle in Middle East and India.
