The SeptiTech STAAR (Smart Trickling Anaerobic/Aerobic Recirculating) filter’s design is a palatable treatment system ideal for various wastewater applications. ETV-EPA verified and NSF/ANSI Standard 40/245 certified, systems from 500 to more than 200,000 gpd flows remove high levels of TSS, BOD and TKN from raw sewage. With an easy, continuous, automatic operation, the filter allows for reliable equalization and clarification process, and maintains low levels of Nitrate-N with all belowgrade components. The low-maintenance designs and low energy input makes it affordable and robust with low sludge production, and designs accommodate peak flow periods and fast recovery after power outages. Modular designs benefit both the environment and communities, and are easily upgradeable to meet growing capacity loads and location-specific demands. 800/318-7967;
