The pre-screening/pretreatment BioSTEP system from Bio-Microbics filters the solids down to 1/8 inch and transfers the screened liquids under pressure to the wastewater treatment system. The prepackaged system can be used in small-diameter, decentralized collections applications. All systems are available as individual components or preassembled in ready-to-install packages. Filtered pump vaults incorporate a slotted filter screen with swabbing handles and integral ScumGuard to provide a submersible pump with protection from large solids and laden scum, allowing for clean-in-place maintenance and quick servicing. 800/753-3278; www.biomicrobics.com.
