Drinking water treatment

Drinking water and high-purity water must meet certain quality requirements to ensure taste and safety. Huahuang can provide professional granular activated carbon (GAC) and coconut shell activated carbon series. It forms a large number of fine pores of various shapes during the activation process and constitutes a huge surface area with adsorption effect. The specific surface area is 500-1200m2/g. The larger the specific surface area, the better the adsorption effect.

Activated carbon can purify urban drinking water, dechlorinate, and deodorize; it is also a high-level purification material in the production process of high-purity water and artificial mineral springs; large boiler feed water can remove harmful impurities such as COD in advance. Granular activated carbon can improve boiler efficiency, extend boiler life, and effectively remove COD, pigments, odors and other toxins in water. Large granular activated carbon can fill filters and purify air, etc.

Wastewater treatment

Activated carbon, used in sewage treatment, can effectively deodorize, decolorize, and remove harmful substances in water. Huahuang can provide granular activated carbon (GAC) and powdered activated carbon (PAC), which are very suitable for different chemical and urban wastewater treatment. With a developed pore structure and good adsorption, it is widely used in waste gas treatment, industrial and domestic water purification, etc.

Activated carbon mainly removes volatile organic compounds (VOC) and chlorine. It can also remove odor, odor, color, residual chlorine, colloids, organic matter (synthetic detergents, pesticides, herbicides, insecticides, synthetic dyes), heavy metals (such as mercury, silver, cadmium, chromium, lead, nickel, etc.). ), is the earliest and most widely used water purification material in water purifiers. Activated carbon is used not only in general activated carbon water purifiers, but also in household reverse osmosis water purifiers, as well as most ultrafiltration, ceramic, KDF, UV and other water purifiers.

Industrial water treatment

Industrial wastewater mainly comes from heavy metal wastewater discharged by mining, smelting, electrolysis, electroplating, pesticides, medicines, paints, pigments, chemicals and other enterprises. If industrial wastewater is not purified, it will seriously pollute the environment. Different production enterprises have different types, contents and forms of heavy metals in industrial wastewater. Therefore, the treatment of heavy metals in chemical wastewater is very important.

Huahuang granular activated carbon and columnar activated carbon are made of high-quality coal. With strong adsorption and high strength, it is very suitable for industrial water purification, decolorization, deodorization, purification and dechlorination and industrial wastewater.

Ultrapure water treatment

Ultrapure water, also known as UP water, refers to water with a resistivity of 18MΩ*cm (25°C). This water has almost no impurities except water molecules, and no organic substances such as bacteria, viruses, and chlorine. Of course, there are no trace elements of minerals needed by the human body, that is, water that has been removed from almost all atoms except oxygen and hydrogen. It can be used to prepare ultrapure materials (semiconductor raw materials, nano-fine ceramic materials, etc.) using distillation, deionization, reverse osmosis or other suitable supercritical fine technologies.

Huahuang coconut activated carbon is the best choice for ultrapure water purification. Its adsorption capacity is related to water temperature and water quality. The higher the water temperature, the stronger the adsorption capacity of activated carbon; if the water temperature is higher than 30 degrees, the adsorption capacity will reach its limit and may gradually decline.
