discussion today on wastewater treatment. (Kim, et al., 1997, No, et al., 2000, Knorr, 1983) Prepare of the chitin, chitosan and regenerated chitosan Chitin prepared from shrimp waste was treated with 0.5 N NaOH at ambient temperatures to hydrolyze the surface flesh. The alkali-treated waste was washed, then dried and disintegrated to obtain powder.

In the last time, the use of natural additives that are biocompatible, are biodegradable, have low toxicity and are from renewable resources attracted attention of many researchers due to their high ability to retain different pollutants from wastewaters. In this context, there are many research studies that highlight the biosorbent ability of chitosan and their composites for the pollutants ...

Carboxymethyl Chitosan Carboxymethyl Chitosan powder is the higher ramification of chitosan, which have 100% water solubility, film forming ability, heavy metal chelation. It has been applied in advanced cosmetics, heavy metal chelating agent, drug sustained release agent, plant growth regulator agent , wastewater treatment, etc.

Chitosan as a Drinking Water Treatment Coagulant. With less efficient coagulation at the higher pH, more biodegradable chitosan monomer remained in solution. Treated water COD levels were higher for chitosan than for alum or ferric. Treated water COD increased somewhat for all three coagulants as the pH increased.

However, chitosan has high degree of hydrogen bonding and polycationic nature owing to the repeated amino groups in its molecular chain resulting in poor solubility in the majority of organic solvents, poor electrospinnability and low productivity [27,28]. Hence, it hinders the pure chitosan nanofibers from the practical wastewater treatment.
