Aquafix - Model ReBuild -Bacteria and Biostimulants Blend

Rapid Biomass Recovery for Upset Recovery and Startup

ReBuild is a powerful tool for fast, effective recovery from operational disruptions and for kickstarting biological activity during wastewater treatment plant startups. This specialized blend of wastewater bacteria and high-performance biostimulants works rapidly to restore biomass, regrow mixed liquor, and stabilize treatment conditions. Ideal for use in any activated sludge process, ReBuild helps operators with plant start up or get back on track after system upsets or influent toxicity.

The bacteria in ReBuild are carefully selected for their flocculation properties, meaning they quickly form dense flocs that improve settling and resist washout—a critical advantage during recovery periods. The biostimulants accelerate the establishment of new bacteria and enhance the resilience of existing microbial populations when used alongside seed sludge. This approach delivers improved BOD removal, clearer effluent, and more robust wastewater microbial health overall.

During plant startup, ReBuild reduces reliance on large volumes of seed sludge by rapidly generating an active and balanced biomass. It’s also highly effective after events such as toxic influent shocks, sludge washouts, and high BOD/COD loading events. Visible signs of stress like ammonia spikes, color changes in sludge, and poor effluent clarity are resolved quickly with targeted application. For optimal results, pair ReBuild with SmartBOD to accelerate sludge regrowth or CounterQuat™ to protect against toxins in the influent.

Trusted by municipal and industrial wastewater operators. ReBuild is a proven solution to help rebuild your system fast and maintain efficient biological nutrient removal. Easy to dose and effective across a range of conditions, it’s your first line of defense in any biological wastewater treatment challenge.
