The EPA recommends 20-25% expansion to effectively clean filter media like anthracite and sand. Insufficient expansion allows \"mud balls\" to form, compromising the filter's ability to remove harmful microorganisms including \u003cem\u003eCryptosporidium\u003c\/em\u003e oocysts and \u003cem\u003eGiardia\u003c\/em\u003e cysts. Raven's portable Media Expansion Measurement System provides an affordable, accessible alternative to costly fixed equipment, making accurate bed expansion monitoring practical for water treatment facilities of any scale. \u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eFeatures:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eAvailable with round or square railing clamp\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e25 foot (7.6m) standard cable length \u003c\/li\u003e\n\u003cli\u003eCustom cable lengths available \u003c\/li\u003e\n\u003cli\u003e1 year warranty\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eHow to Use:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e1) Lower the sensor to rest on the  compacted media bed prior to backwash.\u003c\/p\u003e\n\u003cp\u003e2) Press Zero on the controller to set the counter to 0.\u003c\/p\u003e\n\u003cp\u003e3) As dirt and debris is evacuated, the red light will illuminate.\u003c\/p\u003e\n\u003cp\u003e4) When the backflow water becomes clear, the media will begin to rise with expansion.\u003c\/p\u003e\n\u003cp\u003e5) Raise the sensor just until the red light goes out.
