Sludge is a byproduct of sewage treatment. It is composed of organic matter, fibrous residue, and inorganic material like sand and grit. It has to be agitated or mixed to break down the material for easy disposal. The resulting material can be turned into useful environment-friendly products. However, if the handling is improper, it can do more harm than good. For this reason, it is essential to understand how sludge is produced and what makes it different from other types of wastewater. Read on if you want to learn more about sludge mixing and how Komax sludge heat exchanger takes safe sludge handling to the next level.
The purpose of using a sludge heat exchanger is to improve the efficiency of the sludge handling process and recover energy. Sludge heat exchangers are among the most critical pieces of equipment in a sewage treatment plant. They provide several benefits to the process and improve the overall efficiency.
A typical sludge heat exchanger is made from stainless steel or aluminum alloys with copper, brass or nickel-based alloy for corrosion protection. There is a great variety of sludge heat exchangers available on the market today due to different requirements from different facilities. The Komax Hi-pass mixing technology is patented to eliminate the boundary layer. It gives out a non-clogging hi-pass mixing, which directly helps in energy efficiency improvements.
Sludge mixing systems are used to mix and pump wastewater. It is typically a closed loop, except for an open discharge valve. A sludge mixer consists of a mechanical agitator, a pump, and a tank. The tank is the primary container for collecting and storing wastewater. The agitator mixes the sludge and wastewater to provide a homogenous blend. This mixture then flows through the pump, which sends it through pipes or hoses into various end-use locations or another treatment process.
Komax sludge heat exchangers popularly used in wastewater treatment plants facilitate anaerobic digestion. It makes the sludge mixing process faster and energy efficient. It even avoids vibrations in the equipment that disturb the anaerobic processes and increase costs in equipment wear-and-tear and maintenance.
