What Wastewater Challenge Are You Facing?

High disposal costs
Reduce liquid waste volume before off-site hazardous-waste disposal.
Difficult high-salinity wastewater
Concentrate brines and manage crystallizing or scaling streams.
Water reuse or ZLD targets
Recover distillate for reuse or further treatment based on your required water quality.
Valuable materials in solution
Recover concentrated process liquids, salts, raw materials or by-products where technically feasible.

Engineered Solutions for Complex Industrial Streams

Low-Temperature Vacuum Evaporation

Heat-pump vacuum evaporation at approximately 35°C for wastewater concentration, liquid-waste minimization and distillate recovery. Typical systems are fully automatic and can be customized in corrosion-resistant materials.

From Wastewater Data to a Working System

  1. Submit wastewater information: industry, source, daily volume, analysis and treatment objective.
  2. Technical review: our engineers evaluate volatility, corrosion, scaling and crystallization risks.
  3. Bench or pilot testing: recommended for complex or variable wastewater.
  4. Customized proposal: process, capacity, materials, energy requirements and expected outputs.
  5. Manufacturing and inspection: equipment fabrication, controls integration and factory testing.
  6. Commissioning and support: installation guidance, training, remote monitoring and after-sales service.

Tell Us About Your Wastewater

Send your water analysis, daily capacity and treatment target for a preliminary technical evaluation. Performance depends on feed composition, operating conditions and the required reuse or discharge standard.
