The impact of BOD levels on wastewater

 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.

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 oxygen consumption, thereby reducing the dissolved oxygen content in the water body. This will hinder the survival and reproduction of aquatic organisms, and have a negative impact on aquatic ecosystas.



2. Causing eutrophication of water bodies: High BOD wastewater is rich in nutrients such as nitrogen and phosphorus. When wastewater enters the water body, these nutrients can promote the growth of algae and other plants. Excessive algae and plants can lead to eutrophication of water bodies, causing algal blooms, reducing the transparency of water bodies, and affecting the survival of aquatic organisms.hedp 2na



3. Water hypoxia: After high BOD value wastewater enters the water, due to the need for a large amount of oxygen for microbial decomposition of organic matter, the dissolved oxygen in the water will be quickly depleted. This will lead to insufficient oxygen in the water, making it difficult for aquatic organisms to breathe normally, and even leading to large-scale death of fish and other aquatic animals.

多元醇磷酸酯 PAE

  Performance and Usage : PAPE is a novel water treatment chemical with good scale inhibition and corrosion resistance properties. The introduction of multiple polyoxyethylene groups in the molecule enhances its corrosion resistance and the ability to disperse calcium scale and suspended solids. It effectively inhibits the deposition of barium and strontium scales, which are challenging for existing scale inhibitors, and also provides excellent scale inhibition for sparingly soluble salts like calcium carbonate and calcium sulfate. PAPE offers cathodic protection for steel and is more effective than similar products available domestically. It is miscible with polycarboxylate, organophosphonates, inorganic phosphates, and zinc salts, making it versatile for use with other water treatment agents. The product is suitable as a scale inhibitor for oilfield water injection and as a corrosion and scale inhibitor for circulating cooling water treatment. Technical Specification

What is the function of EDTMPS

 EDTMPS， Ethylenediamine tetramethylphosphonic acid sodium is a nitrogen-containing organic polybasic phosphonic acid mainly used as a cathodic corrosion inhibitor. Compared with inorganic polyphosphates, it has a higher corrosion inhibition efficiency, about 3 to 5 times higher. EDTMPS is miscible with water, non-toxic and pollution-free, with good chemical stability and temperature resistance, and can maintain its scale inhibition effect even at high temperatures of 200 ℃. In aqueous solution, EDTMPS can dissociate into 8 positive and negative ions, forming chelates with multiple metal ions, thereby disrupting the normal crystallization of calcium scale and exhibiting good scale inhibition effects on calcium sulfate and barium sulfate scales. The main uses of EDTMPS include as a corrosion and scale inhibitor for circulating water and boiler water, a chelating agent for cyanide free electroplating, a chelating agent for the textile printing and dyeing industry, and an ox
