REMOVAL OF HARDNESS IN WASTEWATER EFFLUENT USING MEMBRANE FILTRATION

Microalgae cultivation in wastewater: nutrient removal from anaerobic membrane bioreactor effluent.

This study investigated the removal of nitrogen and phosphorus from the effluent of a submerged anaerobic membrane bioreactor (SAnMBR) by means of a lab-scale photobioreactor in which algae biomass was cultured in a semi-continuous mode for a period of 42 days. Solids retention time was 2 days and a stable pH value in the system was maintained by adding CO(2). Nitrogen and phosphorus concentrat...

Biosorptive Removal of Ni(Ii) from Wastewater and Industrial Effluent

The objective of the present work was to investigate the removal of Ni(II) by the fresh biomass (FBM) and chemically treated leached biomass (LBM) of Calotropis procera. The scope of the work included screening of the biosorbents for their metal uptake potential, batch equilibrium, column mode removal studies and kinetic studies at varying pH (2-6), contact time, biosorbent dosages (1-25 g/L) a...

Colour Removal Technology Using Ozone in Textile Industrial Wastewater Effluent: an Overview

The elimination of pollutants from waste water is a serious challenge that needs to be addressed. The conventional treatment process has limitation of not completely removing colour from wastewater. Oxidation with ozone proves to be one of the most efficient methods of treatment of colored aqueous effluent from textile industries. The study highlights the importance of ozone in colour removal t...
