STAAR filter systems from SeptiTech are designed for a simple, automatic and reliable equalization and clarification process to treat high organic loads. The biological trickling filter maintains low levels of nitrate-N with all below-grade components that fit in concrete, plastic or fiberglass tanks. The system is designed to recognize peak, low, intermittent or no-flow conditions, allowing it to go into a sleep mode that dials down activity and eventually shuts all power off until normal flow conditions are detected. It treats 100 to more than 150,000 gpd. 800/318-7967; www.septitech.com.
