Plate heat exchangers can be used as waste water heat exchangers for applications where heat is recovered or released from contaminated liquid (usually water). Typical applications are as follows:

1. Untreated waste water from the sewer

The wastewater flowing into the sewer has a huge thermal potential. This potential can be used to heat water for buildings if it is treated with a Propellentr heat exchange system. The core of the system is a waste water heat exchanger, which is installed on the ground and supplied by pre-treated sewage waste water. The heat extracted from the waste water with this treatment is "pumped" to higher temperature levels. Since the sewer is always located near the building, it can ensure short-distance passage, and the heating supplier and heating consumer are almost neighbors. The reverse is also true-for cooling purposes, heat is removed from the building and passed through a heat exchanger system that leads to the sewer.

2.Waste water from industry production

The 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 waste water, but also waste water from waste water treatment plants, providing a huge heat source. The 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 waste water-heat exchanger-heat pump provides heat energy for the high-performance floor heating of the sewage sludge dryer, and can ensure that the sludge is dried all year round.
