1. Activated sludge method.Municipal domestic sewage is mostly treated by the activated sludge method, which is the most widely used biological treatment process in the world. It has the advantages of high treatment capacity and good effluent quality. This method mainly consists of an aeration tank,
Activated carbon, known for its exceptional adsorption capabilities, is a cornerstone in the field of water treatment, effectively eliminating a wide range of contaminants and improving water quality.
Chlorine is a very important substance in the process of tap water treatment. It has a very good effect on disinfection and improvement of water quality. However, the pollution caused by excessive use and residual substances cannot be ignored. With the improvement of living standards, the awareness
Water is an essential resource for our survival, but unfortunately, it is not always as clean and pure as we would like it to be. Contaminants such as chemicals, pesticides, and heavy metals can find their way into our water sources, posing a serious threat to our health. Thankfully, there is a rema
Coal-based activated carbon for water purification
Activated carbon is a versatile material widely used in various industries for its exceptional adsorption properties. Among the different types of activated carbon available, coal-based impregnated activated carbon stands out for its unique characteristics and numerous applications.
In today’s rapidly developing industrial society, soil pollution has become a major challenge before us. The continuous erosion of pollutants such as sewage, waste gas, chemical fertilizers, pesticides, etc. has caused the soil to lose its ecological functions. In order to solve this serious problem
In recent years, with the decreasing availability of petroleum resources and rapid industrial development, the demand for engine oil has increased significantly. However, the issue of recycling, treating, and utilizing waste engine oil cannot be ignored. Due to its high content of harmful substances
Overview of ozone-biological activated carbon technology1.1 Ozone preoxidationOzone can oxidize and decompose some simple macromolecular organic matter in water, while oxidizing organic matter that is difficult to biodegrade into small molecular organic matter, improving its biodegradability, and ma
Have you ever walked into a room and immediately regretted it because of the funky smell? Or maybe you've encountered a toxic spill and wished there was a way to magically make it disappear? Well, fear not, because coal based granular activated carbon is here to save the day!Now, I know what you're
Activated carbon comes in different forms, and currently granular and powdered forms are still the main ones used in water treatment. Powdered carbon is used for intermittent adsorption, that is, the powdered carbon is added to the water to be treated in a certain proportion, mixed evenly, and the c
1. Filtration speed: 8-12m3/h2. Working temperature: normal temperature working pressure3. Backwash compressed air volume: 18-25L/m2.S4. Filter material layer height: 1000-1200mm, expansion rate 50%5. Backwash intensity: 9-15L/m2.S6. Backwash time: 4-6 minutes
How to accurately use powdered activated carbon can make the water purification effect better and ensure its effectiveness. In fact, as long as you pay attention to the two characteristics of powdered activated carbon, you can make excellent use of powdered activated carbon.First of all, we must pay
1. Water purificationBiological activated carbon refers to a new type of water purification carbon material that allows microorganisms to reproduce in the pores of activated carbon and has aerobic biological activity. Domestic and foreign research and practical applications have shown that in the in
The fine particle size of powder activated carbon facilitates rapid adsorption kinetics, ensuring swift and efficient contaminant removal. Powder activated carbon is different from granular activated carbon in that cannot be used in mobile carbon filters. It is designed for single-use only, meaning
In the process of food production, the national quality inspection department will have a set of strict requirements on product quality, raw materials, packaging, etc., in order to protect the safety of consumers. Therefore, relevant food manufacturers will have strict requirements on their own prod
Activated carbon is used in sewage treatment, and coal-based activated carbon is the first choice. According to the use environment, coal-based granular activated carbon is selected for fixed bed equipment, and coal-based powdered activated carbon is selected for biochemical pool adsorption pool dos
Activated carbon is distinguished by its advanced adsorption properties, thanks to its highly porous structure derived from carbon-rich materials like wood, coconut shells and coal. This structure provides an extensive surface area—up to 3,000 square metres per gram —enabling it to capture a wide ar
If your filter tank space is ideal, then in order from top to bottom: filter cotton, biochemical cotton, activated carbon, ceramic ring, filter cotton. Then it's best to replace the activated carbon once a month or so because it's full.Another point is to pay attention to the PH of the water quality
Introduction to modified/impregnated activated carbon:Modified/impregnated activated carbon uses high-quality columnar activated carbon or granular activated carbon as a carrier and is refined by impregnation (impregnated with silver, copper oxide, molybdenum, phosphoric acid, KOH, NaOH, etc.). It h
