What are the methods of using nutshell activated carbon to treat production wastewater?
Nutshell activated carbon is a kind of activated carbon refined from fine almond shells, peach kernel shells, walnut shells and jujube shells through carbonization, activation, superheated steam catalysis and other processes. It has the appearance of black amorphous particles. Processed by production technology. It has the advantages of good wear resistance, developed gap, high adsorption performance, high strength, easy regeneration, economy and durability.
Nutshell activated carbon can effectively treat four common water reasons:
1. Tap water treatment: The purpose of treating water with nutshell activated carbon is to improve water quality and remove peculiar smells, odors, humus, oil, pesticides, detergents and other substances harmful to the human body.
2. Production water treatment: Shell activated carbon is widely used in various production water treatments. For example, in the brewing industry, cold drink industry and ice industry, activated carbon is used to remove colors, odors, colloidal substances, detergents, pesticides and other organic substances in groundwater, or to remove free chlorine and odors in tap water;coal activated carbon supplier Activated carbon is used to treat boiler water and boiler return water for deoiling in industrial sectors such as, chemical industry; activated carbon is used in the pharmaceutical industry to remove heat sources in water; activated carbon is used in the electronics industry to produce ultrapure water; activated carbon is used in marine industry to produce drinking water; Remove chlorine in the aquarium's tap water. In addition, shell activated carbon is also used to protect ion exchange resins and purify circulating water in factories.
3. Production wastewater treatment: The wastewater discharged from various production processes contains different impurities, but the treatment is simple and easy. Therefore, it should be treated before discharge or recycling.
4. Sewage treatment: Sewage is sewage collected from various waste water, and its composition is very complex. In order to improve the treatment effect and reduce the treatment cost, coagulation precipitation method (physical method), activated carbon sludge method (biological method) and activated carbon adsorption method are usually used. Activated carbon treatment of the husk is usually combined with biological methods, or placed thereafter as the final treatment. After treatment, colors, pesticides, detergents, odors, and BOD, COD, TOC and other impurities can be removed and reused or discharged as industrial and agricultural water.
Nutshell activated carbon is widely used in life, industry, liquid phase adsorption, water purification, and gas phase adsorption.chinactivecarbon.com
Especially suitable for power plants, petrochemicals, oil refineries, printing and dyeing textile industry, food and beverage, medical water, electronic high-purity water, drinking water, industrial water reuse and other industries. It can more effectively adsorb free chlorine, phenol, sulfur, oil, gum, pesticide residues and other organic pollutants in water, residual chlorine, semi-dechlorination value, and recovery of organic solvents.
