Static Mixers Used For Wastewater Processes and Their Benefits

Written by Robert Savage | Apr 7, 2025 10:53:30 AM

Static mixers are indispensable tools in wastewater treatment, ensuring the precise blending of chemicals and uniform distribution of additives - critical for efficient and consistent process outcomes.

Among the benefits of water treatment static mixers are their cost-effectiveness, low energy demand, and operational reliability. However, achieving the best results and return on investment (ROI) depends on choosing the right static mixer, so it is important to consider the specific requirements of each process and the nature of the wastewater being treated. In this article, we’ll consider the different types of static mixers and some of their main benefits.

 

 

Non-Ragging Channel Mixer

Designed specifically to introduce additives into wastewater, the non-ragging channel mixer (NRC) is ideal for processes such as chemical dosing and removal applications in raw sewage. Its design ensures consistent mixing of chemicals with wastewater, leading to enhanced aggregation of solids and improved performance in primary sedimentation tanks. This uniformity enhances efficiency during the removal of contaminants, efficiently preparing wastewater for subsequent treatments.

At Statiflo, our non-ragging channel mixer features:

  • Variable angle control vanes to optimise performance within tight headloss constraints
  • Manual or automatic control vane options
  • Integral accessible sparger for chemical injection
  • Subsurface fixed vanes to boost mixing at low depth
  • Design adaptable for a range of channel sizes, aspect ratios, water depths and flow rates
  • No direct power requirements for mixing

A major advantage of our NRC is its ability to handle wastewater with significant solid and debris content without frequent blockages. Their innovative design minimises the accumulation of solids, significantly reducing the frequency and cost of maintenance. By ensuring smooth, uninterrupted operation, NRCs are particularly useful in high-demand wastewater treatment plants where downtime can directly to operational inefficiencies and rising costs.

Non-Ragging Inline Static Mixer

For processes that involve sludge or wastewater with with rags or fibrous content content, the non-ragging inline static mixer is an excellent solution. With a design that delivers exceptional resistance to clogging, effective mixing is possible even in challenging conditions, reducing operational downtime.

At Statiflo, our non-ragging inline static mixer is highly effective in preventing blockages due to its advanced design. By ensuring smooth flow and reducing the risk of clogging, it enhances system reliability and significantly cuts downtime without compromising on mixing quality, thereby supporting efficient wastewater treatment and capturing vital cost savings.

Our non-ragging inline static mixer is suitable for a range of wastewater treatment processes, including:

  • Sludge blending
  • Sludge thickening
  • Ferric sulphate and ferric chloride dosing for phosphorous removal
  • Coagulant/polymer dosing
  • Chemical dosing of sewage
