99% Pure Sodium Hydroxide Flakes for Industrial Water Treatment

Industrial-grade 99% pure flaky sodium hydroxide (chemical formula NaOH, commonly known in the industry as caustic soda or caustic soda flakes) is a white, opaque, flaky inorganic strong alkali solid. It is highly hygroscopic and water-soluble, dissolving in water with a significant exothermic reaction. It is stable in its alkalinity and exhibits outstanding efficacy, making it a widely used basic inorganic chemical raw material in national industrial production. It possesses compliant market circulation and sales qualifications.

Its core applications are concentrated in water purification and treatment. It can also be used as a highly efficient alkaline cleaning agent, compliantly adaptable to the operation and maintenance of municipal and industrial water treatment plants, and for cleaning and disinfection of food products that do not directly contact food during food processing. All its physicochemical indicators and usage specifications comply with current national chemical product standards and relevant safety regulations for hazardous chemicals management.

In the field of water purification, this product is one of the core agents in water treatment plants, covering the entire wastewater treatment process. It plays a crucial role in the treatment of both industrial wastewater (such as wastewater from chemical, printing and dyeing, and papermaking industries) and municipal sewage. Wastewater generated during industrial production often contains acidic pollutants, heavy metal ions, and various organic impurities. Urban domestic sewage, due to residential discharge, is prone to pH imbalances and excessive suspended solids.

This type of acidic wastewater not only severely corrodes water treatment equipment, pipes, and structures, shortening equipment lifespan and increasing maintenance costs, but also inhibits the activity of microorganisms in biological treatment tanks, leading to decreased pollutant degradation efficiency and affecting wastewater treatment compliance rates.

Industrial-grade 99% pure caustic soda tablets, with their strong and stable alkalinity, can quickly neutralize acidic substances in water, precisely adjusting the wastewater pH to the nationally recommended range of 6.5-8.5. This lays the foundation for subsequent biological treatment, sedimentation, and filtration, ensuring the efficient and orderly operation of the entire water treatment process.

Simultaneously, the hydroxide ions generated upon dissolving in water can chemically react with heavy metal ions such as lead, cadmium, chromium, and mercury in wastewater, forming insoluble hydroxide precipitates. These precipitates can be completely separated and removed through subsequent sedimentation and filtration processes, breaking the heavy metal pollution chain in water bodies at its source.

This helps wastewater meet the "Discharge Standard of Pollutants for Municipal Wastewater Treatment Plants" (GB 18918-2002), achieving compliant discharge or recycling, thus saving water resources and reducing environmental pressure.

Furthermore, this product plays a crucial role in the sludge disposal stage of water treatment. Its alkaline properties can disrupt the cell walls of microorganisms in the sludge, decompose organic sticky substances in the sludge, effectively reduce the sludge's water content, and significantly reduce its volume. This not only facilitates sludge transportation and storage but also reduces the labor and material costs of sludge disposal, further improving the operational efficiency of water treatment plants and lowering overall operating expenses.

This powerful alkaline cleaning agent boasts a 99% purity, stable alkalinity, and is free of impurities. It rapidly emulsifies and decomposes various stubborn greases, heavy oil stains, scale, and organic pollutants, providing significant cleaning results with minimal residue. Suitable for cleaning needs in various industrial and production scenarios, it is particularly ideal for water treatment plants and food processing facilities with high cleanliness requirements.

In the daily operation and maintenance of water treatment plants, core equipment components such as ultrafiltration membranes and reverse osmosis membranes are crucial for water purification. Over long-term operation, organic matter, colloids, and microorganisms in the water adhere to the membrane surface, forming a fouling layer. This leads to decreased membrane flux and reduced filtration efficiency. Failure to clean promptly will shorten the lifespan of the membrane components and increase equipment replacement costs.

The cleaning solution prepared with industrial-grade 99% pure caustic soda tablets can have its concentration adjusted according to the degree of membrane fouling. Through a combination of gentle soaking and circulating rinsing, it quickly penetrates the fouling layer on the membrane surface, efficiently decomposing and stripping organic pollutants, thoroughly removing deposits from the membrane surface, effectively restoring membrane flux, ensuring the filtration effect of the membrane module, extending its service life, and reducing the equipment operation and maintenance costs of water treatment plants.

In food-related applications, the uses of industrial-grade and food-grade sodium hydroxide must be strictly distinguished, and they must not be used interchangeably. Industrial-grade 99% pure caustic soda tablets are only for cleaning and disinfecting equipment, containers, and production environments in food processing workshops and should not be used in direct contact with food or during food processing.

During cleaning, the caustic soda tablets can be slowly dissolved in clean water at a concentration ratio of 0.5%-2%. After stirring evenly, the cleaning solution is prepared. The equipment and containers are then immersed in this solution for 10-20 minutes. Its strong alkalinity rapidly decomposes grease, food residue, and various stains on the equipment surface. Simultaneously, its alkaline properties can destroy the cell walls of microorganisms, inhibiting their reproduction and achieving a dual effect of cleaning and disinfection.

After cleaning, the equipment and container surfaces must be thoroughly rinsed with plenty of running water to ensure no caustic soda residue remains. Only after testing confirms compliance with relevant hygiene standards for food production sites can the equipment be used again, ensuring the compliance and safety of the food production environment from the source.

Furthermore, as an alkaline cleaning agent, it can also be used for cleaning in other industrial settings, such as cleaning oil stains from chemical plant floors and pipes. It provides highly effective cleaning without leaving harmful residues, meeting environmental protection requirements.
