Industrial Wastewater Minimization • Resource Recovery • ZLD
Reduce Industrial Wastewater Volume and Disposal Costs
Customized low-temperature vacuum evaporation and scraped crystallization systems for complex industrial wastewater, valuable-material recovery and Zero Liquid Discharge.
What Wastewater Challenge Are You Facing?
Reduce liquid waste volume before off-site hazardous-waste disposal.
Concentrate brines and manage crystallizing or scaling streams.
Recover distillate for reuse or further treatment based on your required water quality.
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.
Scraped Vacuum Crystallization
Designed for high-salinity, high-viscosity, heat-sensitive and crystallizing materials. A rotating scraper helps control wall buildup and supports discharge of solid or semi-solid concentrate.
Integrated ZLD Solutions
Customized process combinations covering water analysis, testing, pretreatment, evaporation, crystallization, polishing and resource recovery according to the customer’s feed and discharge or reuse objective.
Experience You Can Verify
GRELLIX is the international brand of Qingdao Shuiqing Muhua Environmental Engineering Co., Ltd., integrating process development, equipment manufacturing, engineering implementation and operational support.
Applications
Solutions are developed from feed analysis and testing for applications including metal finishing, electroless nickel, cutting fluids and oily wastewater, RO reject, chemical and pharmaceutical streams, high-salinity brines, biotechnology and process-liquid concentration.
