Wastewater Filter Applications:

Wastewater TSS Removal

A number of AST filters are perfect for TSS removal applications. Our filters can be added to existing systems or easily configured for your specific use case.

Wastewater BOD / COD Removal

COD is composed of readily biodegradable BOD and refractory organics that resist bacterial attack. With a floating bead media filter, COD reduction is accomplished through the extraction of organic particulate matter (TSS removal) and bacterial oxidation of biodegradable dissolved organics (BOD removal). AST’s bead filters can carry out aerobic BOD removal through the filter’s biological activity or direct removal of particulate organics.

Wastewater Nitrification Filter Systems

AST’s bead filter technology utilizes a packed bed of our EN Media which acts as a fixed film reactor with a high specific surface area to completely nitrify wastewaters and meet tight ammonia limits, even in high organic waste streams. AST’s nitrifying filters utilize internal airlifts to provide multiple passes through the system while also keeping the filter completely aerobic to provide high nitrification rates.

Denitrification in Wastewater Treatment

AST’s bead filters utilize the same fixed film mechanics to both nitrify and de-nitrify waste streams for Total Nitrogen control. The High Profile PolyGeyser (HPPG) couples with AST’s unique EN Media has a high specific surface area and can be operated anoxically with carbon addition to de-nitrify effluent streams to meet low TN standards.

Why AST?

Cut Surcharges and Stay in Compliance

Achieve environmental compliance and improve sustainability while also putting surcharge money back into your pocket.

Reduce Operating Cost

Less to break, less to replace. With low cost of ownership and minimal reoccurring costs we strive to produce results not expenses. Air-driven backwash technology provides maintenance-free operation.

Seamless Integration

Filters can be retrofitted or used to upgrade existing systems. For any project, large or small, AST can seamlessly integrate at a fraction of the cost of our competitors.

Modular Approach

A modular approach allows you to expand your treatment system as your production increases. This allows you to grow without major construction and accomplish any level of desired treatment.

Small Footprint

Accomplishes mechanical and biological treatment simultaneously. This process consolidation allows you more room to focus on production, not wastewater.

Environmental Impact

The Green Initiative is a cornerstone of AST Filters. Becoming sustainable is a great way for companies to increase their marketability and to drive business for years to come.

Who We Are:

We have over 20 years of experience engineering and manufacturing advanced water filtration solutions for high-volume applications.

AST was founded in October 1995 to manufacture and market bead filters which were first developed at Louisiana State University’s Civil and Environmental Aquatics Systems Laboratory in the early 1990s by Dr. Ron Malone, who now serves as AST’s President and Chief Technology Officer.

Today, AST’s product line features a variety of different filtration…
