1. Activated sludge technology: Activated sludge technology is a biological method that introduces air into wastewater to allow aerobic microorganisms to multiply and cultivate to form activated sludge with strong adsorption capacity. Biological methods have gradually become the mainstream method of sewage treatment technology. The basic process of activated sludge
In the field of wastewater treatment, PAC (polyaluminum chloride) and PAM (polyacrylamide) are two indispensable chemical reagents, each playing their own role and working together to improve water quality. Then, How do they work? What are the advantages and application areas? Let’s take a look. In Wastewater treatment:PAC acts as a coagulant to condense pollutants through
IntroductionSugar wastewater mainly comes from the sugar production process and the comprehensive utilization of sugar by-products. It is mainly the wastewater discharged from the sugar production process using beets or sugarcane as raw materials, mixed with chute wastewater, sugar pressing wastewater, distillation wastewater, ground washing water and other comprehensive wastewater.
Raw material washing wastewater: This is the largest part of food processing wastewater, usually accounting for 60%-70% of the total wastewater. When washing raw materials such as vegetables, fruits, and meat, a large amount of wastewater containing mud, sand, peels, and minced meat will be generated. This type of wastewater
1.Coking wastewater is a typical toxic and difficult to degrade organic wastewater.Sources of coking wastewater Coking wastewater mainly comes from multiple links in the coal coking production process, among which residual ammonia accounts for the largest proportion, followed by wastewater generated by processes such as coal gas purification and chemical
2. Classification of electroplating wastewater based on pollutant composition and process linksIt can be mainly divided into three categories. 1). Chromium-containing wastewater: mainly hexavalent chromium (Cr⁶⁺), which is highly toxic and carcinogenic. It needs to be converted into low-toxic trivalent chromium (Cr³⁺) through chemical reduction (such as sodium sulfite), and
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
