Slime control for primary filtration systems

摘要: A process and apparatus for protecting a media bed filter with underlying support screen from solids contained in liquid, such as filtrate the filter, used to regenerate or backwash filter. Filtrate enters first collection chamber containing assembly covering one outlet, also second outlet. traverses is transferred addition of predetermined amount bactericide prevent growth therein. Upon bactericide-treated reaching level within chamber, bypasses flows out output further biological treatment use. Bactericide-treated optional surfactant assist cleaning screen. The has an alarm system which detects resistance flow traversing warns that requires replacement, thus fully solids.
