Improvement of coagulation-flocculation process using anionic polyacrylamide as coagulant aid.
A physicochemical treatment (coagulation-flocculation) was applied to a slaughterhouse wastewater, using anionic polyacrylamide as coagulant aid to improve the settling velocity of the flocs formed with the coagulants used: ferric sulphate, aluminium sulphate and polyaluminium chloride. The optimum speed and stirring time for the flocculation stage were ascertained along with the optimum pH and...
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 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 کاملEvaluation of the Coagulation and Flocculation Process Using Plantago major L. Seed Extract as a Natural Coagulant in Treating Paper and Paperboard Industry Wastewater
Introduction: Paper and paperboard industry wastewater has potentially damaging effects on the ecosystem of the receiving environments due to the presence of toxic compounds. As a result, the treatment of such wastewater is necessary prior to discharge into the environment. In this study, the potential of Plantago major L. seed extract as a natural coagulant in treating paper and paperboar...
