Anhydrous Magnesium Sulfate (chemical formula MgSO₄) is a core functional agent in industrial water treatment. With its high purity, strong water solubility, and strong chemical stability, it is widely used in water softening, flocculation and sedimentation, sludge dewatering, and stabilization of circulating water systems. Its anhydrous molecular structure allows for faster reaction rates and higher utilization of active ingredients in water treatment, precisely addressing the challenges of achieving water quality standards in industrial wastewater, circulating water, and drinking water treatment. It is the preferred water treatment agent for industries such as chemical, power, metallurgy, and municipal engineering.

Application Scenarios (Core B-end Needs of Industrial Water Treatment)

1. Water Softening (Circulating Water/Boiler Feedwater Treatment)

· Working Principle: Magnesium ions released after anhydrous magnesium sulfate dissolves react with calcium and bicarbonate ions in the water to form insoluble magnesium carbonate and magnesium hydroxide precipitates, reducing water hardness and preventing scale formation on pipes and heat exchanger surfaces.

· Applicable Scenarios: Industrial circulating cooling water systems, boiler feedwater pretreatment, central air conditioning circulating water softening;

· Core Value: Reduces equipment efficiency decline caused by scaling (e.g., heat exchanger heat exchange efficiency increases by 15-20%), reduces descaling costs, and extends equipment lifespan.

2. Flocculation and Sedimentation (Industrial Wastewater Treatment)

·Mechanism of Action: Under alkaline conditions (pH=8-10), magnesium ions combine with hydroxide ions to form magnesium hydroxide colloid. This colloid has strong adsorption properties, adsorbing suspended particulate matter, COD, and heavy metal ions (such as Cu²⁺, Ni²⁺, Cr⁶⁺) from wastewater, forming large flocs that settle rapidly.

·Applicable Scenarios: Chemical wastewater, electroplating wastewater, dyeing and printing wastewater, mining wastewater, municipal sewage treatment.

·Core Value: Rapidly reduces wastewater turbidity; COD removal rate reaches 30-50%; heavy metal removal rate reaches over 90%, helping wastewater meet discharge standards or be reused.

3. Sludge Dewatering and Conditioning (Municipal/Industrial Sludge Treatment)

· Working Principle: Anhydrous magnesium sulfate, as an inorganic conditioner, adjusts the pH value of the sludge, disrupts its colloidal structure, reduces its moisture content, and enhances the cohesiveness of sludge particles, facilitating dewatering by equipment such as filter presses and centrifuges.

· Applicable Scenarios: Dewatering of sludge from municipal wastewater treatment plants, chemical sludge, and dyeing and printing sludge.

· Core Value: Reduces sludge moisture content from 85-90% to 60-70%, reducing sludge transportation and disposal costs (transport volume reduced by more than 50%) and improving the processing efficiency of dewatering equipment.

4. Other Water Treatment Scenarios

· Drinking Water Pretreatment: Used to remove fluoride ions from drinking water (forming magnesium fluoride precipitate), suitable for drinking water treatment in high-fluoride areas;

· Aquaculture Water Quality Regulation: Adjusts the hardness and pH of aquaculture water, promotes the growth of aquatic organisms, and improves the aquaculture environment;

· Wastewater Reuse Treatment: Used as a deep treatment agent to remove trace impurities from reclaimed water, ensuring that the reclaimed water quality meets production requirements.

Standard Operating Procedures:

1. Dissolution and Preparation: Add anhydrous Magnesium sulfate powder to the dissolution tank at a concentration of 10-20%, stir for 5-10 minutes until completely dissolved (heating to 40℃ can accelerate dissolution) to prepare a mother liquor;

2. Dosing Method: Accurately add the mother liquor to the water treatment system (such as circulating water cooling tower, wastewater reaction tank, sludge conditioning tank) using a metering pump. The addition point should be chosen at a well-stirred location to ensure thorough mixing of the reagent and water;

3. Reaction Condition Control:

· Water Softening: Control the water pH to 7.0-8.0. The dosage should be adjusted according to the water hardness (generally 50-200 mg/L);

· Flocculation and Sedimentation: Control the water pH to 8.5-10.0. It can be used in conjunction with PAC (polyaluminum chloride) and PAM (polyacrylamide) (PAC dosage 50-100 mg/L, PAM dosage...). 1-5 mg/L) to enhance flocculation;

• Sludge conditioning: Add 5-10% of the sludge dry weight, stir well, let stand for 30 minutes, and then proceed with dewatering.

Key Advantages

· High Reactivity: Larger surface area in anhydrous state, resulting in a reaction rate with impurities in water that is over 30% faster than Magnesium Sulfate Heptahydrate, shortening water treatment process time;

· High Concentration of Effective Ingredients: Magnesium ion content reaches over 16% (compared to only about 9.5% for magnesium sulfate heptahydrate), reducing dosage by 40% for the same treatment effect, lowering reagent and transportation costs;

· Strong Chemical Stability: Not easily hygroscopic or decomposed at room temperature, with a shelf life of up to 18 months, suitable for long-term industrial storage;

· Good Environmental Compatibility: The products generated after the reaction (such as magnesium hydroxide and calcium sulfate) are non-toxic, easily precipitated and separated, and the effluent quality meets the "Discharge Standard of Pollutants for Municipal Wastewater Treatment Plants" (GB 18918-2002) and industrial wastewater discharge standards of various industries;

· Multifunctional Adaptability: Combines multiple functions such as water softening, flocculation, and sludge conditioning, and can replace single-function reagents, simplifying water treatment processes. Core Advantages

· Cost Optimization: High concentration of active ingredient, reducing dosage by 40% compared to magnesium sulfate heptahydrate, and transportation costs by over 50%. Long-term procurement can significantly reduce overall water treatment costs.
