Frequently Asked Questions

What is a heat pump-based Zero Liquid Discharge (ZLD) system and how does it work?

Toggle answer

A heat pump-based ZLD system uses energy-efficient heat pump technology to evaporate and condense wastewater, recovering clean water while concentrating and separating solids for safe disposal, ensuring no liquid waste leaves the facility.


Are heat pump-based ZLD systems energy efficient?

Toggle answer

Yes. By reusing latent heat within a closed-loop cycle, these systems consume significantly less energy than conventional thermal evaporation, lowering operational costs and environmental impact.


Can these systems handle high-salinity or challenging wastewater streams?

Toggle answer

Absolutely. Heat pump-based ZLD units can be customized to handle brines, chemical-laden effluents, and other difficult wastewater streams, ensuring compliance with strict environmental standards.


What is the typical lifespan of a heat pump-based ZLD system?

Toggle answer

With proper operation and preventive maintenance, these systems can operate reliably for 15–20 years or more, delivering consistent performance and high water recovery rates.
