The circulating water process is a water treatment technology that effectively utilizes water resources, reduces costs and environmental emissions. It uses a circulating water system to recycle water to achieve the purpose of reducing water consumption and sewage discharge. The circulating water process is an efficient, energy-saving and environmentally friendly
Flocculation sedimentation tanks and inclined tube sedimentation tanks have significant differences in working principles, structural characteristics and application scenarios. 1. Working principle Flocculation sedimentation tank: mainly achieves the aggregation and sedimentation of suspended matter through physical and chemical effects. The flocculation equipment is equipped with a diversion mechanism
1. Structural differences Ultrafiltration (UF) technology is a membrane separation technology that uses pressure difference. It is a physical filtration membrane with a filtration accuracy range of 0.001-0.1 microns. It can effectively remove harmful substances such as rust, sediment, suspended matter, colloids, bacteria and macromolecular organic matter in water, while
I. Project Background and Objectives The coal chemical industry generates a large amount of wastewater in its production process, which contains high concentrations of inorganic salts, organic matter, ammonia nitrogen and other pollutants, posing a serious threat to the environment. In order to achieve clean production and environmental protection, a
What’s the types of sludge? Sludge is a heterogeneous body composed of organic debris, bacteria, inorganic particles and colloids. It is difficult to separate solids and liquids thoroughly through sedimentation. The sludge produced by sewage treatment is a typical organic sludge, which is characterized by high organic content (60%~80%), fine
The carbon source used in water treatment is generally considered to be a carbon-containing element that is easily utilized by microorganisms and promotes the growth of microorganisms. It is a carbon-containing organic matter with a short carbon chain and a simple molecular structure. For example: monosaccharides, polysaccharides, oils and fats,
1. How to clean the RO membrane? Taking reasonable preventive measures can reduce the degree of membrane element contamination, but it is impossible to completely eliminate membrane contamination. 1.1 When does the RO membrane need to be cleaned? ★Water output decreased by about 15% ★The pressure difference between each section
Function: Remove impurities such as granular mud, colloids, microorganisms, etc. in seawater;Purpose: The treated water quality meets the inlet water quality requirements of the reverse osmosis membrane, so that the reverse osmosis membrane can maintain good performance and operation, prevent surface pollution and scaling precipitation of the reverse osmosis membrane
1.1 Project Overview Drilling wastewater generation 610,000 tons/Years, approx.8 ton/h, which contains various salts, chemicals and petroleum residues. 1.2 Water quality analysis The main characteristic pollutants of the drilling wastewater provided by the owner are: oil,TDS, chlorides, etc. Due to the chlorides and TDS concentration up to 200000mg/L and 267588mg/L, biochemical treatment is no longer applicable. Therefore, the
