Abstract Coagulation and flocculation provide a rather straightforward method towards water clarification. However, ongoing debates over worrying health issues linked to chemical coagulants have paved the way to develop plantbased natural coagulants. Natural coagulants are not only water clarifying agents, but they also have antimicrobial and heavy metal removal properties in some instances. Th...

The use of novel flocculants in combination with a sequencing batch reactor (SBR) for the treatment landfill leachate and municipal wastewater has been shown to be an effective method reducing polluted effluents. Co-treatment mixture was performed at 5%, 10%, 15% 20% SBR effluent treated by coagulation–flocculation. 6 d hydraulic retention time (HRT) 30 solids (SRT) removed 58 70% COD, 86 93% a...

abstract  introduction: during extrinsic coagulation pathway, a complex is developed between factor vii, calcium and tissue factor (a cell membrane lipoprotein that is exposed after cell injury). factor vii needs calcium and vitamin k for its biologic activation. coronary artery disease (cad) can be induced by increased level and activity of the coagulation factors vii, viii and ix. in postmeno...

introduction saline wastewaters contain mineral salts which are often produced by industries such as seafood processing, cannery, vegetables, and tanning. they are imported into the sewage collection network. in coastal cities, saline water consumption seems indifferent in household parts and highlevels ofground water, leaksaltwater, precipitation duringdifferentseasons,and sea level are the ot...

colloids are small suspended particles in water which can not be settled or removed naturally due to their light weight and stability. these particles pose some degree of stability and cause water turbidity. there are some concerns regarding colloid removal efficiency in water treatment plants of iran. in this study, the effectiveness of aluminium sulfate and poly-aluminum chloride was evaluate...

Dyes and other chemicals laden wastewater is a main environmental concern for increasing the textile industries in many parts of world. Textile consume different kinds manmade dyes or release huge extents highly polluted water into environment. This excessive dye has great impacts on photosynthetic activity aquatic plants animals, example, fish. It may also affect human health due to presence c...
