This study investigated two methods for the removal of COD and colour from sanitary landfill leachates. The first method involved the use of coagulation/flocculation process using FeCl3 as a conventional coagulant and Ca(OH)2 as base-precipitant. The second method involved integration of Fenton’s reagent into the coagulation/flocculation process. Concentration of FeCl3 that reduced chemical oxy...

This paper present the possible alternative removal options for the development of safe drinking water supply in the arsenic-affected areas. Each alternative option was studied in the Environmental Engineering Laboratory at Indian Institute of Technology (IIT) Kharagpur, India. In this paper conventional precipitation (Alum and Iron salt) and adsorption (With various types of adsorbent) method ...

<p>This goal of this study was to evaluate the effectiveness a new coagulant extract from pumpkin seeds (PSC) for removing turbidity and organic compounds different natural surface waters. Two design experiment methods, namely central composite (CCD) response methodology (RSM) were used optimize PSC removal matter via chemical oxygen demand (COD) water. The CCD results indicated that more...

The purpose of this study was to conduct a literature review determine the understanding current research on use Cassava Peel (CP) in field wastewater treatment, especially as coagulant. This reports types coagulant modification CP, coagulants characterization CP for each modification, performance under various conditions, and applications treatment. takes references from 51 articles period 201...

Ischemic heart disease is caused by a combination of and interaction between a number of genetic and environmental factors. In a study of a group of healthy men from the United Kingdom, such an interaction was identified between the levels of plasma triglycerides and genetic variation determining plasma levels of factor VII, a clotting factor that is associated with risk of ischemic heart disea...

the efficiency of existing municipal wastewater treatment plants has been affected by the increase of incoming organic load caused by the expansions in developing countries. in the present investigation, the effect of chemically enhanced primary treatment (cept) process was studied on the enhancement efficiency of a municipal wastewater treatment plant in tehran, iran. jar test results showed a...
