A Review on Conventional and Alternative Methods for Defluoridation of Water
Abstract: Occurrence of fluoride in groundwater is due to anthropogenic influences on its natural formation and geological settings. Consuming fluoride has both beneficial and detrimental effects on dental and bone structures. This review article is aimed at facilitating precise information on the various methods applied to remove fluoride from water. The defluoridation techniques are divided into coprecipitation, adsorption ion exchange, contact precipitation, electro-coagulation and membrane process. The mechanism involved in each …

Review of Recovery Methods for Acetic Acid from Industrial Waste Streams by Reactive Distillation
Abstract: This paper addresses an industrially important problem of recovery of acetic acid from a wastewater streams via reactive distillation. The separation (or recovery) of organic residues from aqueous waste streams released from chemical and petrochemical industries is critical and indispensable from the points of view of pollution control and recovery of useful materials. The disposal of wastewaters containing most widely used industrial organic acids such as acetic acid, formic acid …

Removal of Heavy Metals using Combination of Adsorbents - A Case Study using Industrial Waste Water
Abstract: Heavy metals are widely used in numerous industries such as paints and pigments, glass production, mining operation, electroplating, battery manufacturing and textile industries. The significant losses of heavy metals occur during the manufacturing processes and these lost heavy metals are discharged in the effluent. As they move from one ecological trophic level to another, metallic species start damaging the ecosystem. They also become difficult to track as they move up …
