Bio-Microbics Offers BioSTEP Pumping System The BioSTEP screened pumping system from Bio-Microbics Inc. is designed to transfer screened liquids in small-diameter, decentralized collection applications. The unit uses SaniTEE screening technology to screen and deflect solids rather than collect and hold them. When the device is being serviced, an external cleaning swab is used to clean the pump vault exterior and flush out the angled slots. A ScumGuard system acts as a shield to protect each unit from oil-laden scum and provides flexible, uniform installation options for most tank, manhole and riser configurations. 800/753-3278; www.biomicrobics.com.Polylok Offers Pressure Filter The Pressure Filter
