“A major water company needed to provide a means for spray cleaning its first stage sewage separation screens. Potable water could not be used in such an applications because of the danger of cross supply contamination and excessive cost, so we had to arrange for a suitably filtered continuous supply from the treatment works’ “final effluent” output. While this is suitable for discharging into the water course, it nevertheless contains enough solid particles to require a normal filtration system to be cleaned at frequent intervals. We therefore specified a Rotorflush Filter-pump which continuously cleans its own filter without the need for manual intervention. Initially, the customer specified water pressure turned out to be more than necessary for the job, but Rotorflush responded very efficiently by quickly modifying and returning the unit, which has since functioned perfectly with minimal attention.”
