With the increasingly strict discharge standards for industrial wastewater, the treatment of high salt wastewater has become a focal point in the global environmental protection field. As a leading domestic manufacturer of environmental protection equipment, Baihuipu Environmental Protection provides customized solutions for industries such as chemical, pharmaceutical, and electroplating with its independently developed MVR evaporator, efficient reverse osmosis system, and composite UV oxidation technology. Its products are exported to Southeast Asia, Europe, and other markets, promoting global industrial green development with high cost-effectiveness and intelligent services.    

        1、 The core challenge of high salt wastewater treatment;  

        High salt wastewater (salt content ≥ 1%) has three core problems due to its complex composition and difficult treatment:;  

        1. Biochemical treatment failure: High osmotic pressure inhibits microbial activity, and the efficiency of traditional biochemical methods drops sharply when the salt content exceeds 2%. The domestication cost of salt tolerant bacteria is high and the stability is poor.    

        2. Limitations of membrane technology: Reverse osmosis membranes are susceptible to organic pollution and blockage, and can only concentrate salt without complete separation.    

        3. High energy consumption and secondary pollution: Traditional evaporation technology consumes more than 70% of the treatment cost, and electrolytic desalination can easily produce dangerous by-products such as chlorine gas.    

        2、 Baihuipu Environmental Protection Core Technology and Equipment Innovation;  

        In response to industry pain points, Baihuipu Environmental Protection integrates the full process technology of "pretreatment+evaporation crystallization+resource utilization" and launches four core equipment:;  

        1. MVR mechanical vapor recompression evaporator;  

      -Technical highlights: Adopting mechanical steam cycle technology, the energy consumption is only 30% of traditional multi effect evaporation. Paired with 316L stainless steel and 2205 duplex steel materials, the corrosion resistance is improved by 50%.    

      -Application scenario: Suitable for chemical and pharmaceutical wastewater with a salt content of ≥ 5%, with a recovery rate of up to 98% and a crystalline salt purity of industrial Class II standard.    

        2. Efficient reverse osmosis (RO) pretreatment system;  

      -Process optimization: Three stage pretreatment (PPF filtration+activated carbon adsorption+softening resin) reduces the risk of membrane fouling, with a desalination rate of over 90% and a freshwater reuse rate of 80%.    

      -Intelligent control: The silent high-pressure pump is linked with an online conductivity meter to achieve unmanned operation, suitable for deep purification of low salt wastewater.    

        3. Composite UV Advanced Oxidation Device;  

      -Functional breakthrough: Targeted adjustment of UV wavelength (180-2400nm), decomposition of large organic molecules, improvement of wastewater biodegradability to over 95%, solving the toxicity problem of pesticide and pharmaceutical wastewater.    

      -Energy saving advantages: Only consumes hydrogen peroxide and electricity, without secondary pollution, and reduces operating costs by 40% compared to traditional processes.    

        4. Multi effect evaporation crystallization system;  

      -Salt separation technology: Combining forced circulation crystallization and falling film evaporation process, high-purity separation of salts such as sodium sulfate and sodium chloride is achieved, and the reuse rate of condensed water reaches 95%.    

      -Case achievement: A refining enterprise in Jinan adopted this technology and recovered nearly 1000 tons of sodium sulfate annually, reducing processing costs to 30 yuan/ton and saving over one million yuan in expenses.    

        3、 Baihuipu's Global Export Competitiveness;  

        Baihuipu Equipment has served customers in over 30 countries, with significant export advantages;  

        1. International certification: Passed CE and ISO certification, meets EU environmental standards, and adapts to water quality requirements in multiple countries.    

        2. Cost advantage: Localized production reduces manufacturing costs and prices are 30% -50% lower than European and American brands.    

        3. Intelligent services: Real time fault diagnosis through remote monitoring system, 24-hour global technical support, spare parts supply covering over 100 countries.    

        4. Customized design: Optimize equipment parameters based on customer water volume (0.5T/H to thousand ton level) and salt characteristics, and support modular delivery in container form.    

        4、 Industry application cases and benefit analysis;  

      -Chemical industry: A certain enterprise in Fujian treats 7.5% NaCl wastewater and recovers 2000 tons of salt annually, achieving "zero emissions" and resource utilization benefits.    

      -Pharmaceutical industry: Jiangsu pharmaceutical companies adopt a combination process of UV oxidation and MVR evaporation, which increases COD removal rate to 90% and evaporation efficiency by 40%.    

      -Electroplating industry: Guangdong customers have introduced RO systems, with a wastewater reuse rate of over 80% and a heavy metal recovery rate of 95%, saving 60% of sewage fees.    

        Baihuipu Environmental Protection is accelerating the layout of integrated processes of "evaporation+biochemistry+membrane technology" and promoting the upgrade of smart water systems:;  

      -Process innovation: Combining electrodialysis (ED) and bipolar membrane technology to convert salt into acid and alkali for reuse, achieving closed-loop circulation.    

      -Intelligent operation and maintenance: Real time monitoring of water quality and energy consumption data through the Internet of Things, predicting equipment maintenance cycles, and reducing failure rates by 30%.    

        High salt wastewater treatment is not only an inevitable choice for environmental compliance, but also a key path for enterprises to reduce costs, increase efficiency, and achieve resource recycling. Baihuipu Environmental Protection takes technological innovation as the engine, providing full chain equipment and services from pretreatment to salt resource utilization, helping global customers move towards a green and zero emission future!
