Description of Active Block Carbon Filter Cartridges(CTO)

The active block carbon filter cartridge is made of high-grade active block carbon with food-grade binder as an auxiliary material and is manufactured by a special extrusion molding process without worrying about the falling off of the toner. This extrusion process needs to ensure a low pressure difference, and can also combine more activated carbon, prolong its service life, and effectively remove organic matter, residual chlorine and other radioactive substances in the water, and have the capacity of decolorization and odor removal.

When the filter cartridge is filtered, the filtrate is first filtered through the fibers of the outer layer, then passed through a filter cloth layer containing activated carbon particles, and finally passed through the inner layer precision fiber filter layer, which has excellent adsorption capacity and filtration efficiency.


Activated carbon filter is suitable for process water and solution purification in semiconductor, electronic device, printed circuit board, electroplating industry, food, and beverage industry. Applicable to the following industries:
Electronics and power industry: pure water, gas, electric liquid, printing line, and so on.
Pharmaceutical and pharmaceutical industry: hospital water, pharmaceutical injections, liquids, etc.
Food industry: food, beverages, drinking water, alcohol, etc.
