1. Properties：

The waste water and sewage have big amount of organic elements, color, metal element which is difficult to be treated. The waste water from papermaking, textile printing and dyeing, food production, coal industry, alcohol factory and plating needs deep purification by activated carbon adsorption.

2. Activated Carbon Adsorption：

According to the different pollutant in the waste water or sewage, we adopt different activated carbons which have high iodine number, high methylene blue adsorption in order to adsorb the organics, metal elements and reduce the COD,BOD,TOC etc.
