Activated carbon for water purification: At present, coconut shell activated carbon is an activated carbon used for purification of drinking water, dechlorination, algae removal, oxygen absorption, and catalytic carrier. It can be used in water purifiers, core fillers, etc. Water purification equipment; can be used for carbon slurry method, heap leaching method and gold extraction, and separation and extraction of precious metals in metallurgical industry, and can also be used for water purification. Coconut shell activated carbon can remove odor, color, residual chlorine, colloid, organic matter, heavy metals, radioactive substances, etc. in water, and is a widely used water purification material in water purifiers. It is not only used in general activated carbon water purifiers, but also in coconut reverse activated carbon water machines and in most ultrafiltration water purifiers.
