DYE WASTEWATER TREATMENT: REMOVAL OF REACTIVE DYES USING
In the present work, we report experimental work on treatment of synthetic waste containing pure reactive dyes, removal of reactive blue dye, using various commercial coagulants such as alum, polyaluminium chloride (PAC), polydiallyldimethylammonium chloride (poly-DADMAC) and polyamines.
In this work, the removal efficiency of chemically treated coir pith activated carbon towards three highly used reactive dyes in the textile industry was investigated. The adsorption capacities of such an activated carbon for the anionic reactive dyes, namely; Procion Reactive Orange 12, Reactive Red 2, and Reactive Blue 4 were determined.

- Polymers are often used as mobility controller for enhanced oil recovery. The present paper deals with the application of partially hydrolysed polyacrylamide (PHPA) polymer in enhanced oil recovery after the conventional water flooding.
- Can partially hydrolysed polyacrylamide polymer improve oil recovery after water flooding?
- The present paper deals with the application of partially hydrolysed polyacrylamide (PHPA) polymer in enhanced oil recovery after the conventional water flooding. Experimental results show that viscosity of PHPA solution increases significantly on addition of small quantity of polymer, which in turn decreases the mobility ratio.
