Making repeated return trips to clean plugged effluent filters decreases productivity and profitability for septic waste haulers. Geoflow Inc. addresses that problem with BioDisc filters, which use Geoshield anti-microbial material to retard slime growth.
The disc filters, which are placed between the effluent pump and the drip dispersal field, are molded from polyethylene resins. That makes them lightweight and durable. With a 120-mesh opening, they trap debris — down to 130 microns in size — that could otherwise plug tubing and drip emitters.
The Geoshield treatment makes the filters unique, says Karen Ferguson, company president.
“The Geoshield material is molded onto the BioDisc filters to stop slime from building up,” Ferguson says. “As a result, the filters last longer and require less frequent cleaning. Septic pumpers will field fewer callbacks for plugged filters.”
Geoshield is made of an anti-microbial material called tributyl tin maleate. It attacks the energy systems that microbial cells require for growth. There’s virtually no discharge of tributyl tin maleate into the environment because it’s not water soluble, Ferguson says.
“It’s used on everything from hulls of boats to shower curtains to sneakers to stop microbial growth,” she says.
The filters can be installed in self-cleaning mode when used with a second filter and two solenoid valves, an application best suited for large commercial systems, Ferguson says. For smaller systems, it’s better to twist the two-piece filter apart for a thorough cleaning.
