PAX Water Technologies Launches PAX Water Mixer (PWM100) for Small Storage Tanks

Vortex mixer utilizes easy, self-install design to provide cost and labor savings for customers

RICHMOND, Calif. – June 06, 2013 – PAX Water Technologies, the leader in advanced water quality technologies for distribution systems, today announced the launch of the PAX Water Mixer (PWM100) for small water storage tanks. The PWM100 features a self-install design, allowing the unit to be easily lowered through the tank hatch, and a vortex flow pattern that is three times more powerful than sheet flow mixers. The mixer can be used to eliminate thermal stratification, reduce residual loss, lower disinfection byproducts and prevent ice formation.

Cold-Weather Cure

Water & Wastes Digest | August 2012

Each winter, water operators in northern climates face a range of challenges due to cold weather, including main breaks and equipment outages. While these emergencies come without warning, they are obvious and visible when they do occur. But in other parts of the water distribution system, cold weather can create a risk that is hidden from view: ice accumulation inside water storage tanks. Often, when operators realize they have a problem with ice in their tanks, it is too late—the tank’s interior is damaged or the wall is punctured.

In-Tank THM Removal System Eliminates THMs For Rural Consecutive System

Tarheel Pipeline| Spring 2012

Stanly County, in central North Carolina, is typical of many smaller rural water utilities in the U.S. Due to excess capacity in the city water system that supplies the surrounding county, Stanly County receives finished water that is often at or above the Maximum Contaminant Level (MCL) for Total Trihalomethanes (TTHMs). Without a treatment plant of its own, Stanly County is limited to few options for bringing their water
into compliance.

Power Makes the Difference in Active Mixing

WaterWorld | May/June '12 Issue

Mixing in potable water storage tanks is increasingly recognized as an important factor in improving water quality and protecting tank assets. Thorough mixing eliminates thermal stratification and ensures uniform conditions in tanks, which has been shown to lower overall disinfectant residual demand and reduce the risk of nitrification. Additionally, mixing can protect and preserve tank assets by preventing the formation of ice (which can scrape tank coatings or puncture tanks), and lower summertime headspace temperatures (which reduces corrosion rates).

In-Tank Aeration Predicts and Reduces THMs

Opflow | November 2011

The Stage 2 Disinfectants/Disinfection Byproducts Rule is presenting tough choice for many water system managers. While some operators have used aeration to reduce Trihalomethanes in storage tanks in the past, it has produced encouraging but inconsistent findings. Now, a Texas utility is using an in-tank sprayer system with good results.

Tame Nitrification with Active Mixing

Opflow | April 2011

For most U.S. distribution systems using chloramination, nitrification is a leading water quality concern. However, by combining active mixing with regular tank maintenance and efficient operation, nitrification can be tamed in even the most challenging climates.
