Abstract

The feasibility of treated industrial wastewater as mixing water and effect of its constituents on cement mortar was experimentally evaluated. Cement mortar specimens were cast using deionised water (DW), tap water (TW), treated paint industry wastewater (TPIWW), and presence of zinc (Zn), lead (Pb), copper (Cu), cadmium (Cd), nickel (Ni), iron (Fe) and chromium (Cr). The results, when compared with the results of reference specimen made with DW, showed that TPIWW significantly and TW insignificantly increased the setting times and were made indistinguishable strength variations. Compressive and flexural strength increased as the concentration of metals increased, when compared with reference specimens. Therefore, TPIWW is found to be suitable for mixing water in cement mortar with no adverse effects and metal ions are positively interacted with cement mortar.

Abstract

Textile effluents pose considerable impact on soil and water due to indiscriminate discharge of partially/untreated effluent. Development of effective treatment technology for colour removal is difficult, since dyes are continually being upgraded to suit market demands. This investigation aims at feasibility of sorption for colour removal of spent orange dye effluent using powdered activated carbon (PAC). Experimental results show that the colour removal efficiency is maximum (93%) at pH 2 for a dose of 1.5 g/L of PAC.
