aqua heat process wastewater heat exchangerProcess wastewater heat exchanger is designed to recover heat from wastewater obtained as a result of technological processes in many branches of industry. Our equipment is adjusted to take in hot wastewater directly from the machinery where it is generated or averaged sewage from the entire manufacturing plant. The exchanger depending on installation requirements can be made in the shape of a cylinder or a cube, standard material – stainless steel 304, optionally the exchanger can be made out of acid resistant steel 316.



  • Underground
  • Ground-based (free standing – inside buildings)
  • Ground-based (container enclosure – outside)

Heat exchanger efficiency after warm-up amounts to 70%

The exchanger can be used for majority of process wastewater due to its design that facilitates easy maintenance.

The heat can be recovered while wastewater flows, i.e. 1 l of wastewater = 1 l of warm water, the other option is that warm water can be stored in containers or buffer tanks.
