RB Organic process and supply over 30,000 tonnes of organic vegetables every year. As part of the process soil is washed from the vegetables and the resulting dirty water requires treatment prior to discharge. Historically, the water was treated with chemicals and passed, by batch process, through clarifiers where solids were settled out. Being faithful to the philosophy and ideals of organic farming, RB Organic were keen to eliminate the use of chemicals and reduce the level of labour associated with desludging an chemical dosing operations. The site produces 170m cube of wash water per day which has to meet a standard of less than 30mg/l Suspended Solids and 50 mg/l BOD prior to discharge.
