Reduction of Turbidity of Water Using Locally Available Natural Coagulants
Turbidity imparts a great problem in water treatment. Moringa oleifera, Cicer arietinum, and Dolichos lablab were used as locally available natural coagulants in this study to reduce turbidity of synthetic water. The tests were carried out, using artificial turbid water with conventional jar test apparatus. Optimum mixing intensity and duration were determined. After dosing water-soluble extrac...
متن کاملWater Melon Seed as a Potential Coagulant for Water Treatment
This paper reports the potential of watermelon seed as a natural coagulant for water treatment. It was aimed at identifying watermelon seed as a possible replacement for alum and other synthetic polyelectrolytes in treating water. Laboratory scale studies using jar test experiments were performed on medium turbid water to determine the effect of dosage, pH stirring time and speed on coagulation...
متن کاملChitosan as a Drinking Water Treatment Coagulant
Inorganic aluminum or iron salts have been used for many decades to coagulate colloidal particles in surface water prior to flocculation, sedimentation and/or filtration. Although effective, inorganic coagulants have several disadvantages including large chemical dosages required for treating eutrophic waters, large volumes of chemical sludge produced, and toxic effects of metallic coagulants o...
متن کاملEvaluating the Efficiency of Tragacanth Coagulant Aid in Removing Colloidal Materials and Suspended Solids Creating Turbidity from Karun River Water
Introduction: Colloidal materials and suspended solids cause turbidity in water. To remove turbidity, clarification method is used that includes processes of coagulation, flocculation, and sedimentation. Due to the long duration of coagulation process, coagulant aids are applied. Despite the favorable efficiency of synthetic polyelectrolytes as a coagulant aid, due to their harmful effects on h...
متن کاملProteins from Natural Coagulant for Potential Application of Turbidity Removal in Water
Coagulation-flocculation followed by sedimentation and filtration is the most commonly used water treatment process , in which turbidity or particles removal is strongly dependent on proper coagulant dosage, effect of pH ,effect of time, jar test and settling column tests were perform. In the method the seeds were treated with different solvents of NaCl and NaOH to extract the active coagulant ...
