Maintain the Quality of Treated Water During Storage with In-Tank Mixers

It’s not enough to simply store clean water in your water tank – the water quality must be maintained through tank mixers and water tank mixing technology. Thermal stratification and high-water age in storage tanks can cause residual loss, bacterial growth and public health risks. Warm temperatures can lead to disinfectant loss and ammonia buildup, creating nitrification. Ice formation due to freezing temperatures can also significantly damage a tank. In-tank mixers, submersible mechanical devices, are installed easily without service disruptions or tank modifications and mix on-demand to create temperature stability, uniformly distributing drinking water disinfectants and improving municipal water quality.

 We install and service in-tank water mixers to help operators meet AWWA and EPA regulations and maintain the quality of treated water in the distribution system cost-effectively.

Our solutions

Water Tank Mixers


In-tank active water mixers are motorized pieces of equipment that create a powerful vortex flow inside water storage tanks to circulate the entire volume from top to bottom. Using in-tank mixers along with maintaining a continuous and powerful water circulation reduces nitrification, prevents ice formation in cold climates and eliminates thermal and chemical stratification even during periods of low demand and increasing water age.

Value of active in-tank water mixers

  • Maintains quality of drinking water in storage tanks cost-efficiently: Regularly using a water tank mixer reduces the need for costly tank repairs, and additional water treatment.
  • Improves quality of aging water in tanks by maintaining thermal stability and uniform chemical distribution: Unmixed water can lead to an undesirable chlorine to ammonia ratio, as well as the formation of nitrite and nitrate, demonstrating the criticality of installing water tank mixers.
  • Prevents ice damage, minimizing future maintenance needs: Ice build-up can damage steel and cause interior coatings to deteriorate more quickly. Moreover, repeated thaw-freeze cycles can put undue stress on joints. Tank mixers evenly distribute and move water, maintaining your tank infrastructure.
  • Reduces thermal stratification, minimizing disinfectant loss: During thermal stratification, colder, denser water sinks. In this process chlorine also sinks, making non-chlorinated strata more susceptible to biological growth. Water tank mixers manage tank temperature by moving water around within the tank, supporting disinfection.
