The heat transfer plate of the wide-channel sewage heat exchanger is made of stainless steel, which not only has high corrosion resistance, but also has an inclined plane. After polishing, dirt is difficult to deposit and adhere to the surface. The sewage flows from top to bottom along the heat exchange surface, and the sewage in the back continuously washes the sewage in front, making the heat exchanger difficult to scale, thus prolonging the service life and reducing the cleaning times of the heat exchanger.

The wide channel sewage heat exchanger is specially designed for sewage heat exchange. The sewage channel adopts the wide channel type, which has good internal trafficability and is not easy to block.

Sludge dewatering and digestion

High temperature=high energy recovery. This simple formula is applicable if the Prepler waste water heat exchanger is supplied by the sludge from the digestion tank of the sewage treatment plant or the filtrate from the sludge dewatering system.

The temperature in the biogas digester is about 36 ° C, but this high heat has never been used before. Due to its special design and automatic cleaning, the waste water heat exchanger can ensure continuous high heat transfer with these media.

The recovered energy can be directly used to preheat the raw sludge on site. From the perspective of energy conservation, the hydrostatic primary pressure of biogas digester does not require additional feed pump.

Effluent from sewage treatment plant

heat exchange system is an economical and environmentally friendly energy treatment system, which is also applicable to operators of sewage treatment plants. Because it is not only untreated wastewater, but also wastewater from wastewater treatment plants, providing a huge heat source. The increasing amount of water and cooling water has opened up a new way to improve the energy efficiency of the whole sewage treatment plant. The sludge dryer not only uses solar radiation as drying energy, but also uses the heat potential of the effluent from the sewage treatment plant. The process chain sewage treatment plant wastewater - heat exchanger - heat pump provides heat energy for the high-performance floor heating of sewage sludge dryer, and can ensure the drying of sludge throughout the year.
