Chitosan Coagulation to Improve Microbial and Turbidity Removal by Ceramic Water Filtration for Household Drinking Water Treatment

The use of porous ceramic filters is promoted globally for household water treatment, but these filters are ineffective in removing viruses from water. In order to increase virus removal, we combine a promising natural coagulant, chitosan, as a pretreatment for ceramic water filters (CWFs) and evaluate the performance of this dual barrier water treatment system. Chitosan is a non-toxic and biod...

The Study of Coagulation Process in Medium Turbidity Removal from Drinking Water Using Various Inorganic Coagulants: A Comparative Study

Background and aims:  Colloidal impurities are one of the natural contaminants in surface water that cause turbidity and color. Turbidity in spite of create undesirable appearance, can be a haven for disinfection of microorganisms. This study aimed to evaluate the effectiveness of various coagulants in removing average turbidity of water and also their impact on the electrical conductivity and ...

Coagulation and Flocculation Treatment of Wastewater in Textile Industry by Using Chitosan

Aluminum sulfate (alum), ferrous sulfate, ferric chloride and ferric chloro-sulfate were commonly used as coagulants. However, a possible link of Alzheimer’s disease with conventional aluminium based coagulants has become an issue in wastewater treatment. Hence, special attention has shift towards using biodegradable polymer, chitosan in treatment, which are more environmental friendly. Moreove...

Modeling and Optimization of the Coagulation–Flocculation Process in Turbidity Removal from Aqueous Solutions Using Rice Starch

Natural coagulants have received much attention for turbidity removal, thanks to their environmental friendliness. The present study investigates potential application of rice starch for removal of turbidity from aqueous solutions. It considers the effects of four main factors, namely settling time (40-140 min), pH (2-8), slow stirring speed (20-60 rpm), and rice starch dosage (0-200 mg/L), eac...
