This product is a fully organic scale inhibitor and corrosion inhibitor specifically designed for power plants, composed of a copolymer of multi-functional organic phosphonic acid, phosphonic acid carboxylic acid, and copper corrosion inhibitor. It interacts with divalent metal ions in water, making insoluble substances less likely to settle, keeping crystals in a small particle range and exhibiting lattice distortion effects, thus providing good dispersion performance for calcium carbonate scale; the copper corrosion inhibitor can form a dense protective film on the surface of equipment, alleviating the corrosion rate. This product is specifically used for scale inhibition and corrosion inhibition in the cooling water of condensers in thermal power plants. Its effectiveness is also very significant under high pH values and high concentration ratios.

This product is an efficient liquid scale inhibitor/dispersant used to control scaling caused by the precipitation of silicates, carbonates, sulfates, and iron oxides in membrane separation systems. It can effectively control the scaling of silica, calcium carbonate, calcium sulfate, barium sulfate, and strontium sulfate. It has sufficient dispersing ability to disperse blocking particles on the membrane surface; it is suitable for all major membranes; effective over a wide range of feed water pH; compatible with aluminum and iron oxides in the feed water; can be added directly or diluted for addition. It is suitable for different water sources. Using this scale inhibitor/dispersant can extend the system cleaning cycle, prolong the membrane life, and reduce operating costs. It is particularly important to note that if the raw water contains a high amount of Si, long-term operation can lead to the deposition of Si on the surface of the reverse osmosis membrane, causing contamination. Using this scale inhibitor/dispersant can extend the system cleaning cycle, prolong the membrane life, and reduce operating costs.

This product is a highly effective bactericide and algaecide based on active chlorine. Unlike solid chlorine products, it does not cause the system to produce white scale while disinfecting and eliminating algae. For water bodies that have already developed algae or have a lot of system slime, a shock dosage of this product at 100-200 mg/L can quickly kill and remove them. It works better when alternated with active bromine or quaternary ammonium salt bactericides and algaecides. It is suitable for industrial circulating cooling water in various industries. It is usually recommended to use a shock dosage, with a dosing concentration of 60-80 mg/L.

This product is an aldehyde-based biocide, highly effective and low in toxicity. It has a killing and inhibiting effect on heterotrophic bacteria, sulfate-reducing bacteria, and iron bacteria in oilfield systems. It does not produce drug resistance. This product includes an enhancer, which changes the past shortcomings of single-agent use, such as bacterial drug resistance and high usage costs. It is suitable for industrial circulating cooling water and oilfield injection water in various industries. It is recommended to use a shock dosing method, with a dosing concentration of 50-100 mg/L.

V529 is a broad-spectrum, highly effective bactericide and algaecide that acts quickly by breaking the protein bonds in microbial cells, thereby inhibiting cellular respiration and the synthesis of adenosine triphosphate, leading to microbial death. Microorganisms can no longer synthesize enzymes or secrete adhesive substances and biofilm-forming materials before cell death. It is widely used in industrial circulating ion cooling water systems, breweries, paper industry, and other fields as a bactericide, algaecide, or slime prevention agent.
