SeptiTech STAAR (Standard/Denite) Filter Systems

SeptiTech has designed affordable and sustainable wastewater treatment products for properties not hooked up to a public sewering system. Relentless research, development and continuous product improvement goes into producing the most effective, reliable, highest value and owner-friendly wastewater treatment systems in the industry.

These systems help ensure a clean environment and opportunities for water reuse.

Offering simple, low-cost and robust treatment solutions, the SeptiTech® STAAR™ Filter Systems are a low-energy treatment option using an anaerobic-aerobic sequence (AAS) bioreactors. The primary anaerobic pre-treatment tank settles, clarifies and manages the sludge return, then followed by a secondary aerobic treatment process.

The residential and commercial SeptiTech® STAAR™ Filter Systems are environment-friendly, regulatory-approved and preferred for private, business, and government applications. With exceedingly stringent Nitrogen Removal standards, these advanced wastewater treatment systems (AWTS) utilize an award-winning Trickling Filter Technology and has a successful track record from 100 gpd – 150,000+ gpd.
