AquaBlend - Water Storage Tank Mixing
Mixing is an effective tool for meeting regulatory requirements for control of microbial contaminants and reduction of disinfectant byproducts. Potable water storage tanks are kept mostly full (greater than 70%) in order to provide a sufficient quantity of water for maintaining desired pressures, peak demand, fighting fires, and for other supply emergencies. Daily volume levels often do not fluctuate more than 5-10%, creating stagnant water and thermally-stratified layers within these tanks. Aged water can completely lose its disinfectant residual, resulting in bacterial regrowth and waterborne illness.
AquaBlend provides mixing in water storage tanks by firing short bursts of air through NSF-compliant piping and engineered nozzles using a food-grade, oil-free compressor. The AquaBlend controller air injection valve intermittently fires to blend from the tank bottom to the water surface. The large
bubbles formed create a distinctive mixing pattern, or "tank roll." |
