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...

A study on the treatment of Kraft pulp mill effluent by ozonation alone, and by combined treatment of ozonation preceded by chemical coagulation, activated carbon adsorption or membrane filtration has been conducted. Initial effluent pH was a major factor deciding the treatment efficiency. When ozonation was conducted alone, more than 70% reduction of color and phenolic compounds could be achie...

The convergence between complement and the clotting system extends far beyond the chemical nature of the complement and coagulation components, both of which form proteolytic cascades. Complement effectors directly enhance coagulation. These effects are supplemented by the interactions of complement with other inflammatory mediators that can increase the thrombogenicity of blood. In addition, c...

This work studied the combination of a chemical coagulation/flocculation step with an aerobic biological process, using feed-batch operation, to treat real paint manufacturing wastewater (PMW). The results indicate that the combination of coagulation flocculation and biological process is an efficient alternative in the treatment of PMW. For initials COD of 18590 mg/L, BOD of 1492 mg/L and colo...

Landfill leachate is an important pollution factor resulting from municipal landfill sites. Physical and chemical processes are the better option for pretreatment or full treatment of landfill leachate. This article presents a combination of pre-treatment method (coagulation and adsorption) for leachate collected from municipal solid waste open dumping site. Physico chemical characteristics of ...

The coagulation curve obtained by the technique previously reported by the authors has been recently interpreted by J. B. Graham and E. M. Barrow as explainable to a large extent by a variation of the ionic force of the medium during dilution. In order to overcome the influence of this physico-chemical factor and to reveal the action of the biological coagulation factors, the authors have perfo...

Industrial sector is a backbone of the economy throughout world. Despite that there are lot benefits; such as development urbanization, major contributor in economy’s growth sign industrial development. There adverse effects on environment including depletion and damage our natural precious resources. Textile, cement, paper pulp, sugarcane, food, pharmaceuticals, chemical, paint other industrie...
