Potable Water: How Mixing Improves Water Quality in Storage Tanks

The implementation of continuous, active mixing technologies combined with periodic disinfectant boosts can maintain water quality by eliminating sampling inconsistencies and the thermal stratification that leads to the breakdown of disinfection chemicals.

Potable Water: How Mixing Prevents Ice Buildup and Stratification

Quiescent waters in potable water storage tanks are associated with water quality problems such as thermal stratification, biofilms, excessive disinfection byproducts and disinfectant residual loss. Ice formation in distribution-system reservoirs is another challenge faced by water utilities in northern climates during winters. Thick layers of ice often form at the surface in storage tanks during prolonged periods of subfreezing weather. Steel tanks can expand during ice formation, causing structural damage and water leakage.

Wastewater: Three Approaches to Controlling Odors

Long-distance circulators are different from any other reservoir equipment in that the adjustable intake takes advantage of the manner in which water forms
thin horizontal layers in ponds and allows a precise horizontal cross-section of water to be circulated throughout the entire pond footprint.
