Evaporator Concentrator

Product Details

Evaporator Concentrator, an evaporator for concentration serving as the first stage of the Zero Liquid Discharge (ZLD) process. It uses a vacuum system together with a Heat Pump to evaporate wastewater at a low temperature of about 35–45°C, reducing wastewater volume and increasing the concentration of the solution, while recovering high-quality distillate for reuse. The Heat Recovery system reuses the latent heat from condensation, helping to reduce electricity consumption, before sending the concentrated solution on to the Crystallizer stage.

Key Features: Evaporator Concentrator
  • Vacuum evaporation at a low temperature of 35–45°C
  • Heat Pump with Heat Recovery for energy savings
  • Forced Circulation reduces scaling
  • Recovers low TDS/COD distillate for reuse
  • Corrosion-resistant construction such as SS316, Duplex and Titanium
  • Fully automatic control with PLC
Benefits: Evaporator Concentrator
  • Dramatically reduces the volume of wastewater requiring disposal, cutting off-site disposal costs
  • Recovers clean water for process reuse
  • Serves as the concentration stage ahead of the Crystallizer for achieving ZLD
  • Fast ROI thanks to the energy-saving heat pump
Working Principle: Evaporator Concentrator
  • 1. Wastewater is heated under vacuum, lowering the boiling point to 35–45°C, using the hot side (condenser) of the heat pump.
  • 2. The water evaporates into vapor.
  • 3. The cold side (evaporator) of the heat pump condenses the vapor into distilled water, and the released latent heat is drawn back to continue evaporating the wastewater — energy that would normally be lost is reused within the system.
  • 4. The greatly reduced volume of concentrate is passed on to the next stage.
Supported Industries
  • Metals and surface plating
  • Chemicals and pharmaceuticals
  • Food and beverage
  • Cosmetics
  • Printing
  • ZLD projects requiring wastewater volume reduction before crystallization
Product Highlights
  • Reduces wastewater volume while recovering high-quality distillate for reuse
  • Saves energy with a Heat Pump and a latent heat reuse system
  • Forced Circulation system reduces scaling
  • Supports extension to a Crystallizer so the ZLD system can operate completely

Evaporator Crystallizer

Evaporator Crystallizer, an evaporator and crystallizer for the final stage of the Zero Liquid Discharge (ZLD) system. It uses vacuum to concentrate wastewater up to the saturation point in order to separate salts and solids as dry crystals, while recovering almost all of the distillate for reuse, enabling the system to achieve complete Zero Liquid Discharge. Suitable for wastewater with high TDS and a high solids content, using a Scraped Surface system to reduce scale build-up on the heat exchange surface.

Static Screen
PRE TREATMENT

Static Screen

The Static Screen / Wedge Wire Screen is used for preliminary wastewater treatment, using gravity to separate solids from wastewater without electricity and with no moving parts. It is made of SUS304 stainless steel wedge wire screen, with selectable slot openings of 0.25–3.0 mm, supporting a maximum flow rate of approximately 270 m³/hr. It helps reduce TSS and protects pumps and valves in the treatment system.
