Weihai Greenlan Water TreatmentEquipment Co., Ltd.
About
Weihai Greenlan Water Treatment Equipment Co., Ltd., based in Weihai, Shandong Province, China, manufactures low-temperature vacuum evaporation, crystallization, and concentration equipment for industrial wastewater treatment. With nearly 20 years of experience, over 100 patented technologies, and more than 5,000 installations worldwide, Greenlan specializes in treating high-salt, high-concentration, and high-COD wastewater streams that conventional processes cannot handle effectively. The VESALT-ME thermal crystallizer series uses steam power and operates at approximately 35 degrees Celsius under vacuum with an internal scraper mechanism to prevent crystal wall adhesion, producing solid crystals with moisture content at or below 10%. The VESALT-HP heat pump crystallizer runs entirely on electricity without steam or cooling water. The IVECDEST-VE heat pump evaporator achieves COD reductions up to 99% with fully automatic unattended operation. The NT/CTSALT disc film dryer performs one-step drying and crystallization yielding solid waste with moisture as low as 1%, while the MVR disc film dryer reduces energy consumption by over 45% compared to conventional designs. The MTR double-effect evaporator provides multi-stage heat recovery for improved energy efficiency. Greenlan serves landfill leachate treatment, chemical processing, and diverse industrial sectors with fully automated, unattended operation across its product line.
Key Products
Steam-powered crystallizer that evaporates wastewater under negative pressure at 35°C with internal scraper preventing crystal buildup, producing solid crystals with moisture ≤10% and clear distillate.
Electric-powered crystallizer requiring no steam or cooling water, operating at 35°C under negative pressure with automatic solid waste discharge and distillate production.
Uses heat pump-generated heat to separate water from pollutants at ~35°C, reducing COD by up to 99% with fully automatic unattended operation, producing reusable distilled water.
Steam-powered disc structure that dries and crystallizes wastewater in one step, leaving trace dry solid waste with moisture as low as 1% and 99% COD reduction.
Mechanical vapor recompression disc dryer that reduces energy consumption by over 45%, treating wastewater in one step with solid moisture content ≤1%.
Double-effect evaporation system for concentrating industrial wastewater using multi-stage heat recovery for improved energy efficiency.
