Wastewater Treatment for a Changing World
The world's population is growing; and the increased demand on water resources has forced lifestyle changes with an emphasis on water conservation and reuse. Although water conservation helps to preserve our precious water resources, conservation also makes concentrations of pollutants in wastewater stronger. Additionally, new chemicals introduced into the waste stream everyday from agricultural, industrial and pharmaceutical industries make it more challenging to treat water than ever before.

FAST® wastewater treatment systems are proven, innovative treatment products that provide robust, high-performance treatment to meet the challenges of our changing world. Suited for use in countless applications, a versatile FAST system is ready to serve your needs. FAST® is designed to be efficient, dependable, easy to install and very user-friendly. FAST is tremendously beneficial alone or in combination with other processes to meet the rigorous demands of the most challenging and complex projects. Retrofitting of existing activated sludge plants with FAST technology is an affordable, dependable way to significantly upgrade performance with minimal impact in time and operation.

Maintains Exceptional Growth
FAST's media provides a high surface-to-volume ratio to maintain exceptional microbial growth during low, average and peak usage. Bacteria become "fixed" or attached to the stationary media where the abundant, diverse and self-regulating population of microbes is consistently maintained in the aeration zone to metabolize the waste. FAST maintains stable performance because the abundant bacterial population is attached to the media and does not wash out of the aeration zone. During times of low usage, the large volumes of thriving organisms delay a dying-off of the system, making FAST well suited to intermittent use applications. Unlike conventional activated-sludge (suspended-growth systems), bacteria grow on the media and feed on incoming waste, leaving the circulated liquid essentially clear and free of solids.

Stable Operation
High levels of bacteria and other useful microbes (including stalked ciliates and rotifers) in the bioreactor aeration zone provide a stable operation, break down biodegradable constituents, prevent bulking conditions and settling problems, and yield a significantly longer sludge age than conventional systems. A long sludge age achieves nitrification and denitrification, operates effectively in cold climates, and produces less sludge.
