Posted by Water treatment agents, also known as water quality stabilizers, are essential for industrial water, domestic water, and wastewater treatment processes
Chaical agents can be used to meet certain quality requiraents for water. Its main functions are to control the formation of scale and sludge, reduce foam, reduce corrosion of materials in contact with water, raove suspended solids and toxic substances in water, deodorize and decolorize, and soften water quality. In order to prevent the discharge of industrial wastewater from causing harm to the environment and improve the reuse rate of industrial wastewater, environmental protection regulations in various countries and regions are becoming increasingly strict. All of this has led to the rapid development of water treatment technology, and various water treatment agents have also aerged. Including coagulants, flocculants, corrosion inhibitors, scale inhibitors, fungicides, dispersants, cleaning agents, pre film agents, defoamers, decolorizers, chelating agents, deoxidizers, and ion exchange resins.
Water treatment agents are divided into two categories: organic water treatment agents and inorganic water treatment agents. In order to achieve more effective buffering
The purpose of corrosion, scale inhibition, and sterilization is to better improve the environment, control pollution and public hazards caused by sewage discharge, and gradually develop and promote the use of new organic water treatment agents. The overall development trend is that more and more inorganic water treatment agents are gradually being replaced by organic water treatment agents. Like polyphosphate, although inexpensive, it has certain scale and corrosion inhibition properties. But due to its poor thermal stability, it is prone to hydrolysis. Due to its incompatibility with oxidizing biocides, its application is limited, and it is gradually being replaced by organic phosphonic acids such as HEDP, ATMP, EDTMP, and polyphosphonic acid. Organic water treatment agents mainly include organic phosphonic acid and water-soluble copolymers, with water-soluble copolymers mainly consisting of acrylic acid copolymers. Monomers include acrylic acid, maleic anhydride, sulfonic acid monomers, etc. Organic phosphonic acid refers to organic compounds containing phosphonyl groups directly connected to carbon atoms in their molecules. The molecule also contains functional groups such as carboxyl, hydroxyl, and amino groups. It is a water treatment agent promoted around the 1970s. Compared with inorganic polyphosphoric acid, organic phosphonic acid has good chaical stability due to its h3 C-P bond, which is not easy to hydrolyze and degrade. It can withstand high taperatures, has a small dosage of drugs, and has a significant solution limit effect. It is a non stoichiometric scale inhibitor with good synergistic effects. So the aergence of organic phosphonic acids has taken a big step forward in water treatment technology and has been widely applied in water treatment and other industries. At present, commonly used products both domestically and internationally include ATMP, HPDP, PBTC, etc. Organic phosphonic acid water treatment agents have therefore become a global research topic and direction of effort since the 1970s.
