Industrial waste management
Industrial waste must be handed over to authorised companies that manage it; the cost of handling industrial waste varies from 12 € to 120 € depending on the type
of waste.
Whenever biological treatment is not possible due to extreme conditions for microorganism, then waste products must be treated by Membranes or Evaporation.
Examples:
- Water coming from washing tanks that contain chemicals.
- Waste water from chemical industries that include for solvents and salts.
- Brine (water with high salt content) from olives factories and others.
- Waste water from workshops (coming from machining works, etc).
- Pig manure.
- Evaporation.

Unicus®, a guarantee for the mechanical compression
Mechanical vapour recompression works with low temperatures differential and it is the most economical solution for handling (evaporation/concentration) industrial
waste because it involves the lesser energy consumption.
The success of the HRS Spiratube's solution is based on the union between Unicus® and Mechanical Vapour Recompression
equipment:
- Unicus® guarantees no fouling in the evaporator so it can operate all the time necessary without stops.
- Unicus® achieves high levels of concentration.
- The Mechanical Vapour Recompressor is key for energy saving.
