Biological Activated Carbon Filter could provide ideal habitats for invertebrates, but invertebrates may lead to aesthetic problems and adverse health effects of drinking water. This paper studied the invertebrates in biological activated carbon filters in a water plant of the south of China during Sep. 2006 to Sep. 2007. The results implied that BAC filters were colonized by invertebrates, in which 23 species of invertebrates were found, the dominating organism group was the rotifer, and others included Copepoda, Cladocera, Oligochaeta, Nauplii and Nematoda.

We used wood tar as a blending agent to produce shaped activated carbon and the abrasion resistance of it is larger than 85%; the BET surface area is 1577.55m2/g. The abrasion resistance of unshaped activated carbon is 80% and BET surface area is 1789.87m2/g. The ash contents of powdered activated carbon, and unshaped activated carbon prepared by physical method are less than 0.2%; the iodine number is 1200 mg/g; the maximum 0.15% methylene blue adsorption value is 18ml/0.1g.
