Low Temperature Heat Pump Evaporator System

Smart. Sustainable. High-Efficiency Water Recovery.

System Overview

A next-generation evaporation system designed to treat high-TDS industrial wastewater using advanced heat pump technology. Operating under vacuum at low temperatures, the system efficiently evaporates water, condenses vapors into high-quality distillate, and recovers salts as dry solids — delivering a complete Zero Liquid Discharge (ZLD) solution.

Technology Heat Pump Vacuum Evaporation
Operating Principle Low Temperature Evaporation under Vacuum
Energy Source Electricity (Heat Pump) — No Steam Required
System Type Closed Loop, ZLD Solution

Key Performance Metrics

85% – 95%

Key Benefits

Energy Efficient

(Up to 70% savings — no steam, boiler, or cooling tower required)

High Performance

(85–95% water recovery, distillate quality <100 µS/cm)

Robust Operation

(Handles high TDS & complex effluents — integrated agitator + scraper prevents scaling)

Compact & Modular

(Skid-mounted design — quick installation & minimal space requirement)

Low Maintenance

(Reduced fouling — minimal operator dependency)

How It Works

1

Wastewater is heated using recirculated hot water from a heat pump

2

Evaporation occurs at low temperature under vacuum

3

Vapors are condensed using chilled water from the same heat pump

4

Concentrated slurry is separated into dry salt cake and reusable water

Closed-loop system No external heat source required

Business Impact

Significant Reduction in Effluent Disposal Cost

High-Quality Distillate Recovered for Reuse

Zero Liquid Discharge Compliance Achieved

Reliable 20-Hour Continuous Operation
