The optimization of coagulation-flocculation process in a conventional treatment water plant

Abstract

The assurance of the protection for the delivered drinking water against the secondary pathogenic increases in the distribution network will become a prime importance target for water treatment plants. In the waterworks there are used the multi barrier concept, and each treatment step will have to be optimized to obtain a maximum reduction of the compounds which are a health hazard to consumers. The optimization of the coagulation flocculation process in order to obtain an advanced reducing of suspensions, organic substances and microbiological constituents has a positive effect on the other technological phases such as decantation, filtration, disinfection, ensuring the risk reduction of bacterial growth in the distribution network.

Nitrate Water Contamination from Industrial Activities and Complete Denitrification as a Remediation Option

“…There are a variety of mitigation and remediation strategies for removal of high NO 3 − concentrations in both water and soil, which can either be biological [90] or chemical [91]. Nitrate is removable in low amounts is possible by conventional physical water remediation techniques such as filtration, sedimentation, flocculation, and coagulation; however, due to its water solubility and various oxidation states, these methods are not always feasible [19,92]. Biological systems are applied globally to remove NO 3 − in industrial wastewaters, although mostly without the production of N 2 as the terminal product of the system [42].…”
