The main components of oxidative bactericidal and algal killing agents usually include the following:
Chlorides: such as sodium hypochlorite (NaOCl), trichloroisocyanuric acid (TCCA), dichloroisocyanuric acid (DCCA), etc. These compounds oxidize and destroy the cellular structure of microorganisms by releasing chlorine, thereby achieving bactericidal and algal killing effects.
Peroxides: such as hydrogen peroxide (H2O2), persulfate, etc., can release reactive oxygen species, which have strong oxidation ability and can effectively kill bacteria, viruses, and algae.
Bromine preparations: such as bromochlorohydrin (BCDMH), these compounds destroy microbial cell walls and membranes through oxidation, leading to leakage of cell contents and ultimately killing microorganisms.
Ozone: Ozone (O3) is a strong oxidant that can effectively kill bacteria, viruses, and algae in water, while also degrading organic matter.
Chloramine: Chloramine is a compound formed by the reaction of chlorine and ammonia, such as monochloroamine (NH2Cl) and dichloramine (NHCl2), which have long persistence and can maintain a long-lasting bactericidal effect in water.
Stabilizers and corrosion inhibitors: In order to improve the stability of oxidizing bactericides and reduce corrosion on metal equipment, stabilizers and corrosion inhibitors are usually added.
These components can be combined and proportioned differently based on the specific use and purpose of the bactericidal and algal agents.

Surfactants are a type of chemical substance, also known as surfactants. They can reduce the surface tension of liquids in water or other solvents, making them easier to disperse, emulsify, and dissolve other substances. The molecular structure of surfactants gives them both hydrophilicity (hydrophilic groups) and hydrophobicity (hydrophobic groups), which allows them to form a thin film on the surface of the liquid and alter its surface properties.
Surfactants have a wide range of applications in various fields, including cleaning agents, personal care products, food processing, agriculture, medicine, lubricants, etc. In cleaning agents, they help remove dirt and grease; In food processing, they are used as emulsifiers and stabilizers; In personal care products, they endow products with foam and cleaning ability; In the field of medicine, they are used for drug delivery, etc.
Overall, surfactants play an important role in modern industry and daily life, providing critical support for the manufacturing and functionality of many products.

Non ionic surfactants are a type of surfactant that do not produce ions in aqueous solutions. This means that they will not decompose into positively or negatively charged ions in aqueous solutions. Unlike ionic surfactants (such as cationic or anionic), the molecular structure of non-ionic surfactants does not contain dissociatable ionic groups.
The general structure of non-ionic surfactants includes a hydrophilic (polar) head and one or more hydrophobic (non-polar) tails. The hydrophilic head is usually an ether bond structure containing multiple oxygen atoms, such as a polyoxyethylene (EO) chain. Hydrophobic tails are usually long chain hydrocarbons.
Some of the main characteristics of non-ionic surfactants include:
Mildness: They are usually less irritating to the skin and eyes, so they are commonly used in personal care products such as shampoo, shower gel, and detergent.
Foam stability: compared with ionic surfactants, non-ionic surfactants can also produce stable foam in hard water.
Compatibility: They can be compatible with various types of chemicals, including other types of surfactants, making them very useful in formula design.
Cleaning ability: Non ionic surfactants have good cleaning ability and are commonly used in cleaning products.
Biodegradability: Many non-ionic surfactants have good biodegradability and are environmentally friendly.
Low temperature stability: They can also maintain stability at low temperatures and are suitable for cleaning agents that need to be used under low temperature conditions.
Common non-ionic surfactants include:
Alkyl phenol polyoxyethylene ethers (APEOs), such as nonylphenol polyoxyethylene ethers (NP EOs) and octylphenol polyoxyethylene ethers (OP EOs).
Fatty alcohol polyoxyethylene ethers (AEOs), such as sodium dodecyl sulfate (Laureth).
Polyoxyethylene fatty acid esters, such as polysorbate.
Polyethylene glycol fatty acid esters, such as carbitol.
Non ionic surfactants are widely used in fields such as cosmetics, pharmaceuticals, textiles, paints, cleaning agents, and agriculture. However, some types of non-ionic surfactants, such as APEOs, are gradually being replaced by safer and more environmentally friendly alternatives due to their environmental and health risks.

KR-801 is a cationic polymer compound of cyanoguanidine series, which has various functions such as decolorization, flocculation, and CODcr degradation. It is mainly used to treat wastewater from high concentration and high chromaticity dyes, printing, and intermediate dyeing processes, especially for the treatment of wastewater from reactive dyes, acidic dyes, and dispersed dyes.
KR-801 water decolorizing agent can be used to treat industrial wastewater in industries such as textiles, printing and dyeing, pharmaceuticals, papermaking, and chemical industry, with a decolorization rate of over 95% and a CODcr removal rate of over 65%. When using, it is recommended to dilute KR-801 with 10 to 40 times water and directly add it to the wastewater. After stirring for a few minutes, precipitate or perform air flotation to obtain clear water after decolorization. In addition, adjusting the pH value of wastewater to 7 to 10 can improve treatment efficiency. When the color and CODCr value of the wastewater are high, in order to save treatment costs, KR-801 can be alternately used with polyaluminum chloride (PAC), but KR-801 and PAC cannot be mixed together. Whether to add polyaluminum chloride first or use KR-801 first should be determined based on laboratory testing and processing.

1、 Performance and Usage
DTPMPA is a non-toxic chaical substance that can dissolve in acidic solutions. It has excellent scale and corrosion inhibition effects and good taperature resistance performance. This substance can inhibit the formation of carbonate and sulfate scales, and exhibits better scale and corrosion inhibition performance than other organic phosphines in alkaline and high-taperature environments (above 210 ℃). In the field of water treatment, DTPMPA is widely used as a scale and corrosion inhibitor for circulating cooling water and boiler water. Especially suitable for alkaline circulating cooling water, it can be used as a pH regulator, and can also be used as a scale and corrosion inhibitor for oilfield water injection, cooling water, and boiler water with high carbonate content. In addition, DTPMPA can be used as a peroxide stabilizer, especially under high taperature conditions, which has a better stabilizing effect on hydrogen peroxide. It can also serve as a chelating agent in textile printing and dyeing processes, a dispersant for pigments, an oxygen delignification stabilizer, a carrier for trace elaents in fertilizers, and a concrete additive. In addition, it has also been widely used in fields such as papermaking, electroplating, metal pickling, and cosmetics. In addition, DTPMPA can also be used as a stabilizer for oxidizing fungicides.
