  Biochaical Oxygen Daand (BOD) is one of the important indicators for measuring the organic matter content in wastewater. The BOD value reflects the content of biochaical organic matter in wastewater and is also an important parameter for evaluating the degree of pollution of wastewater to the water environment. hedp 4na BOD refers to the amount of oxygen required by organisms to decompose organic matter under aerobic conditions over a certain period of time. Organic compounds in wastewater can be utilized by microorganisms as energy and carbon sources for biochaical degradation. Therefore, the higher the BOD value in wastewater, the higher the content of organic matter in wastewater, which means that the pollution level of wastewater to water is also more severe. hedp Wastewater with high BOD values will have the following impacts on the water environment: 1. Deterioration of water quality: The release of wastewater with high BOD values into the water body can lead to an increase in

  EDTMPA belongs to organic phosphoric acid and is a highly efficient polar corrosion inhibitor solvent that can dissolve and has strong chelating force. When used alone, its effect is already good, and it can also cooperate with some non-ionic and anionic polymers to increase its surface activity and permeability. It is recommended to mix it with PAAS (sodium polyacrylate), HPMA (hydrolyzed polymaleic anhydride, ultra-high heat resistance above 300 degrees) or PASP (sodium polyaspartic acid, strong anti settling effect on calcium and barium salts, good descaling effect). Please refer to it as appropriate. In addition, my suggestions can only be used for water treatment, and may not be suitable for solvents or strong acid-base aqueous solutions. If it is in these environments, please provide specific explanations.

 PBTCA (p-phenyltricarboxylic acid) produced by Kerry Chemical is a commonly used scale inhibitor with good scale inhibition and slow-release performance. Below, I will briefly discuss the scale inhibition and slow-release performance of PBTCA. Scale inhibition performance: PBTCA can form complexes with calcium ions and stabilize them, preventing their deposition and crystallization in water. This effectively inhibits the generation of calcium scale and prevents blockage of pipelines and equipment. PBTCA can also inhibit the formation of other scale such as phosphates and carbonates, maintaining the cleanliness of the water system. Sustained release performance: PBTC A can extend its scale inhibition effect by slowly releasing active ingredients. It can adsorb on the metal surface to form a protective film, reduce metal corrosion, and prevent the attachment of scale. The slow-release performance of PBTCA enables it to continuously exert its scale inhibiting effect for a long time, red
