Vietnam's Environmental Protection Law 2022 explicitly requires industrial enterprises to have a wastewater reuse rate of ≥ 60% and strictly control the discharge of total dissolved solids (TDS). However, traditional biological methods and membrane processes are difficult to cope with high salt wastewater from electroplating, chemical industry, etc., and evaporative crystallization equipment has become a necessity. As a leading wastewater treatment solution provider in Asia, Baihuipu Environmental Protection has provided compliant and low-cost wastewater reduction services to over 30 Vietnamese enterprises with its independently developed low-temperature evaporation and concentration system. The annual export volume of equipment has increased by 200%, making it a recommended technology supplier for Vietnam's environmental protection department.    

        Part 1 Pain Points for Vietnamese Enterprises: Why is High Salt Wastewater Treatment So Difficult?    

      -Technical bottleneck: Microbial inactivation and increased risk of membrane blockage when salt content exceeds 5%;    

      -High cost: Traditional multi effect evaporation energy consumption accounts for over 60% of operating costs;    

      -Regulatory risk: fines for illegal emissions can reach hundreds of millions of Vietnamese dong, and even face closure;    

      -Land restrictions: Industrial park land is tight, and equipment needs to be miniaturized and integrated.    

        Baihuipu Solution:   

        ✅ Low temperature evaporation+intelligent frequency conversion: operating at 40 ℃ low temperature, the water consumption per ton is only 25kW · h (reducing consumption by 65% compared to traditional technology);    

        ✅ Modular design: Single machine daily processing capacity of 5-200 tons, supporting parallel connection of multiple units, saving 50% of land occupation;    

        ✅ Salt recovery: can extract industrial salts such as sodium chloride and sodium sulfate, creating additional revenue;    

        ✅ Cloud management: Real time monitoring of water quality and energy consumption data, automatic generation of compliance reports, and response to environmental inspections in Vietnam.    

        Part 2: Advantages of Whirlpool Equipment: Why Have We Obtained Long Term Repurchase from Vietnamese Customers?    

        2.1 Technical Hard Power: Patent Certification+Localization Adaptation;  

      -Core technology: Possessing 12 evaporator structure and anti scaling patents (patent number: ZL2023XXXXXX);    

      -Material upgrade: The corrosion resistance of the titanium alloy evaporator has been increased by three times, making it suitable for the high temperature and high humidity environment in Vietnam;    

      -Local compliance: Passed Vietnam STAMEQ certification and meets TCVN 5945:2023 industrial wastewater discharge standards.

        Part 3: Successful Cases in Vietnam: The Leap from "Pollution Control" to "Resource Utilization";  

        Project Name: Zero Discharge of Wastewater from a Chemical Industrial Park in Haiphong City, Vietnam;  

        Challenge:   

        -Wastewater type: Acidic wastewater containing 15% sodium sulfate and COD 5000mg/L;    

        -Original processing method: Outsourcing transportation, with an annual cost exceeding 8 billion Vietnamese dong (approximately 2.4 million yuan);    

        -Policy requirement: Processing within the park must be achieved by the end of 2024.    

        Baihuipu Plan:;  

        -Deploy 2 sets of HTE-100 low-temperature evaporation systems, integrating pH adjustment and pretreatment modules;    

        -The daily processing capacity is 200 tons, and the clean water is reused in the cooling tower. The purity of sodium sulfate reaches 98% (available for sale);    

        -Achievement:   

        -Annual savings of 7.6 billion Vietnamese dong in outsourced disposal costs;    

        -The annual revenue from by-product salt is approximately 1.2 billion Vietnamese dong;    

        -Obtained the "Green Factory" certification from the Ministry of Natural Resources and Environment of Vietnam.    

        The Vietnamese government plans to phase out 60% of highly polluting wastewater processes by 2025, resulting in a market gap of over 1 billion US dollars in environmental protection equipment.
