Health Impact due to Pollution from the Fine Chemical Manufacturing Industries Operating at Gove Industrial Belt of Bhiwandi (Maharashtra)
Abstract: The present study performed to understand the toxicity level of heavy metals like Zn+2, Ni+2, Cu+2, Cr+6, Fe+3, which are present in the industrial effluents released from fine chemical industries situated at Gove industrial belt, Bhiwandi, Maharashtra. The concentration level of Zn2+ in the present study was found to be 26.35 ppm which was above the limits of 5.0 ppm set by CPCB in industrial wastewater discharge. Such high Zn2+ …

Use of Rice Straw as an Adsorbant to Eliminate Waste Color of Textile Industry Wastewater
Abstract: Textile wastewater contains different colors which are harmful to the environment. The removal of dyes from effluent using adsorption process provides an attractive alternative treatment, especially if the adsorbant is inexpensive and readily available. In this present research paper natural adsorbant rice straw is used for removal of color from waste effluent of textile industry. The adsorbant prepared was employed for the removal of color at the different doses. The …

Effect Of Different Shapes Of Air Diffusers On Removal Of Chemical Oxygen Demand Of Wastewater In Activated Sludge Process
Abstract: AbstractOne of the challenges faced in activated sludge process is the low solubility of oxygen in wastewater, affecting the microbial activity due to mass transfer limitations and ultimately hampering the effluent quality. To overcome this limitation various types of diffusers have been in use but the configuration in which the aerators must be placed is still an open question. A series of experiments were conducted using different shapes of diffuser …

Treatment of Textile Industrial Wastewater using Hydrophilized Polyamide Nanofiltration Membrane for Water Recovery and Reuse
Abstract: The textile industry is very water intensive. Water is used for cleaning the raw material and for many flushing steps during the entire production process. During the process a large quantity of wastewater is produced which consists of dyes, heavy metals, pigments, and surfactants in high concentration levels all around the world. Dyes and other chemical laden wastewater released by textile industries is a major concern for the treatment which …
