The plate heat exchanger can be used as a waste water heat exchanger. It is suitable for occasions where heat is recovered or released in contaminated liquid (usually water).Typical applications are as follows:
    1. Untreated wastewater from the sewer
    The wastewater flowing into the sewer has a huge thermal potential. If Propellent heat exchange system is used for treatment, this potential can be used to heat water for buildings. The core of the system is the wastewater heat exchanger, which is installed on the ground and supplied by pre-treated sewage wastewater.
    2. Effluent from sewage treatment plant
    Propellent heat exchange system is an economical energy treatment system and is also suitable for operators of sewage treatment plants. Because it is not only untreated wastewater, but also wastewater from wastewater treatment plants, it provides a huge heat source. The ever-increasing amount of water and cooling water has opened up new ways to improve the energy efficiency of the entire 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 heating of the sewage sludge dryer, and can ensure that the sludge is dried all year round.
    3. Sludge and filtrate after sludge dehydration and digestion
    High temperature = energy recovery. If Propellent wastewater heat exchanger is used for the sludge in the digestion tank of a sewage treatment plant, or the filtrate supply of the sludge dewatering system, this simple formula applies.
    The temperature in the biogas digester is about 36°C, but this high heat has not been used. Due to the 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 original sludge on site. From the perspective of energy conservation, the hydrostatic primary pressure of the biogas digester does not require an additional feed pump.
    4. Industrial wastewater
    Like the municipal sector, the wastewater flow of industrial enterprises also loses a lot of energy. Especially in physical and chemical processes, very high temperatures can be reached.
    Many companies now work 24 hours a day so that they can provide continuous traffic. In most applications, the recovered energy can be directly introduced into the industrial process, thereby shortening the length of the production line. The heat extracted from wastewater has positive side effects and can meet emission requirements.
