The difference between RO reverse osmosis membrane and ultrafiltration membrane First, the reverse osmosis membrane (RO membrane): RO is the abbreviation of Reverse Osmosis membrane in English. Chinese means (reverse osmosis). Generally, the flow of water is from low concentration to high concentration. Once water is pressurized, it will flow from high concentration to […]
(1) Connection ring type: buckle the horizontal rings of the two skeletons into the semi-circular grooves of the connection ring. The connection ring type is a relatively stable connection method, but its processing procedures are relatively cumbersome, the cost is high, but the strength and verticality are better. At present, many large filter bag dust […]
The filter bag is the key element that determines the dust removal efficiency and working temperature of the bag filter. The cost of replacing the filter bag is also the main maintenance cost of the bag filter. Therefore, the working life of the filter bag is related to the operating condition and cost of the […]
The dust collector frame is also called the dust collector bag cage, also known as the dust collector frame. The framework of the dust collector is the rib of the filter bag. It should be lightweight and easy to install and maintain. The quality of the frame directly affects the filtration state and service life […]
The filter bag is damaged When the bag filter is working normally, the wear of the dust on the filter bag’s surface will cause “needle” holes in the bag after a long period of wear. Sometimes during the cleaning process, under the impact of low-pressure wind speed and large airflow, the bag will also be […]
Common pharmacy With reasonable water treatment process and deep treatment with water, the treated water can reach GB5084-1992, CECS61-94 water recycling water standard, etc., can be recycled for a long time, saving a lot of water resources. The following are commonly used pharmaceuticals for wastewater treatment: (1) Flocculant: Sometimes called coagulant, it can be used […]
Approach 3.Biological treatment Through the metabolism of microorganisms, the wastewater, which is a solution, a colloid and a micro-suspended organic pollutant, is converted into a stable and harmless substance wastewater treatment method. According to the different microorganisms, the biological treatment method can be divided into two types: aerobic biological treatment and anaerobic biological treatment. Aerobic […]
Approach 1.Physical processing The method of separating and recovering undissolved suspended state pollutants (including oil film and oil beads) in the wastewater by physical action can be classified into a gravity separation method, a centrifugal separation method, and a sieve filtration retention method. The processing unit belonging to the gravity separation method has sedimentation, floating […]
Wastewater type Industrial wastewater B.heavy metal wastewater Heavy metal wastewater mainly comes from wastewater discharged from mines, smelting, electrolysis, electroplating, pesticides, medicine, paints, pigments and other enterprises. If the heavy metal wastewater is not treated, it will seriously pollute the environment. The types, contents and forms of heavy metals in wastewater treatment vary with different […]
Wastewater type Industrial wastewater Many types of pollutants are produced in industrial production, and the types and concentrations of pollutants produced by different industries are significantly different. A . electroplating wastewater The main source of zinc in electroplating and metalworking wastewater is electroplated or pickled tow. The contaminants are transferred to the rinse water by […]
