The WFS Series Water Filter Systems are designed to handle high volumes of industrial waste water. These completely automatic treatment units will collect your dirty wash water and process it so that it can be reused in the washing operation. The WFS draws the wash water from your collection sump and transfers it to the holding and collection tank. The solids separator removes much of the heavy sand and grit and deposits it in the collection container for disposal. Additional solids that settle in the holding tank are also deposited in the collection container.
The Filter System not only cleans the water, but also adds an oxidizer reagent to kill bacteria and odours. The oxidizer is used to make the water more environmentally friendly and less hazardous for personnel doing the washing. Rinsing normally uses fresh water which is collected with the wash water. Any excess water can be automatically disposed of as treated water, more easily achieving compliance with environmental regulations2
