What is Hydraulic Retention Time (HRT) ? Hydraulic Retention Time (HRT) refers to the average residence time of water or sludge in the treatment system in the reactor, that is, the average reaction time of sewage or sludge and microorganisms in the bioreactor. It is one of the important parameters
What is an upflow anaerobic sludge blanket (UASB reactor) ? The UASB reactor is an efficient and energy-saving wastewater treatment technology that mainly uses anaerobic microorganisms to degrade organic matter in water and purifies wastewater through biodegradation reactions. How does a UASB reactor work? Wastewater enters the reactor through the
The anoxic/aerobic process is a sewage treatment method that connects the front anoxic section with the rear aerobic section in series . How does A/O works? The A/O process hydrolyzes organic matter such as starch, fiber, and carbohydrates in sewage through heterotrophic bacteria in the anoxic section to improve its
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
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
