One, the challenge of high salt wastewater: why do we need professional silicon and hardness removal?
High salinity wastewater (TDS> 10000mg/L) is commonly found in industries such as power, chemical, and pharmaceutical, and its characteristics include:;
-Silicates: prone to scaling and blockage of pipelines, affecting the lifespan of membrane systems;
-Hardness ions: cause equipment corrosion and reduce thermal efficiency;
-High salt content: Traditional biochemical methods are ineffective and require physical and chemical treatment. Baihuipu Environmental Protection has developed a "pretreatment+cascade purification" process to address pain points and achieve synergistic removal of silicon, hard substances, and salts.
2、 Baihuipu Environmental Protection Core Technology: Four Step Efficient Purification Process;
one Preprocessing: Adjusting pH and coagulation precipitation;
-Add high-efficiency coagulants (such as polyaluminum chloride PAC) to adjust the pH of the wastewater to alkaline, so that the silicate ions (SiO ∝⁻) can be converted into colloidal particles;
-Cooperate with flocculant (PAM) to form large flocs, and precipitate to remove more than 80% of silicon and suspended solids.
two Chemical softening: deep removal of hardness;
-Using the "lime soda ash method", Ca (OH) ₂ and Na ₂ CO ₂ are added to react with Ca ²+and Mg ²+to produce CaCO ₂ and Mg (OH) ₂ precipitates;
-Optimize the dosage ratio, achieve a hardness removal rate of>95%, and reduce the risk of scaling in the subsequent membrane system.
three Special adsorption: targeted silicon removal;
-Using modified activated aluminum adsorbent to selectively adsorb residual soluble silicon, reducing the silicon content to<10mg/L;
-Baihuipu's patented adsorbent material is recyclable, reducing operating costs by 30%.
four Membrane Integration Process: Salt Separation and Resource Utilization;
-Combining nanofiltration (NF), reverse osmosis (RO), and evaporative crystallization (MVR) to achieve salt classification and recovery;
-The produced water meets the Design Specification for Industrial Circulating Cooling Water Treatment (GB50050-2017) and can be reused for production.
3、 Five advantages of Baihuipu technology;
one Efficient and stable: silicon removal rate ≥ 95%, hardness ≤ 50mg/L, effluent meets strict industry standards;
two Low cost: adsorbent regeneration technology+cascade salt separation design, reducing the cost of reagents and energy consumption;
three Anti impact load: adaptable to fluctuations in high salt (TDS below 50000 mg/L) and high silicon (500mg/L) wastewater;
four Resource utilization: Recycling industrial salts (NaCl, Na ₂ SO ₄) to create economic value;
five Intelligent control: PLC automatic dosing system reduces manual intervention and ensures stability.
Fourth, Application Scenarios: Supporting Green Development in Multiple Industries
-Coal chemical industry: coal gasification ash water removal of silicon and hardness, achieving zero emissions;
-Photovoltaic manufacturing: synergistic treatment of silicon powder and hardness in cutting wastewater;
-Pharmaceutical industry: high salt mother liquor desilication pretreatment to ensure stable operation of the evaporation system.
Case: In a desulfurization wastewater treatment project at a power plant, the Baihuipu process reduced the silicon content from 200mg/L to 8mg/L, saving over 2 million yuan in annual operation and maintenance costs.
