Electrochemical treatment of sugar industry wastewater: process optimization by response surface methodology

Abstract: Wastewater from sugar industry has multiple combinations of organic and inorganic contaminants. It has an adverse impact on nearby environment and requires specific type of treatment to minimize the effect. To treat the sugar industry wastewater, an attempt has been made with the electrochemical process by using aluminum electrode. Four process parameters were selected, namely initial pH (pH 4–10), current density (44.5–133.5 A/m2), electrode spacing (10–20 mm), and experimental time (20–100 min) to optimize the condition with surface response methodology. At optimum condition maximum, 69.2% chemical oxygen demand and 88.6% color reduction were archived at pH 7, current 1 A, electrode distance 1.5 cm and treatment time 60 min. The coefficient of the model predicted (R2) value of 0.87 and 0.48, and adjusted (R2) value of 0.64 and 0.45 for chemical oxygen demand and color reduction were obtained. The physicochemical characteristic indicates that settling sludge has more inorganic material as compared to floating sludge; hence, settling sludge has low calorific value than floating sludge.

Microbial Detoxification of Residual Organophosphate Pesticides in Agricultural Practices

Abstract: Bioremediation is a term which defines the use of microorganisms for the removal of pollutants or other toxic agents from a contaminated site or industrial waste. Microorganisms provide natural defense mechanisms to counter the need to get rid of the pollutants and to maintain a less toxic environment. Almost every industry generates some amount of waste products that are released in the environment leading to pollution and thus efforts are being needed and made to remove these pollutants from the environmental resources or at least detoxify them to prevent their hazardous effect on human population. Agriculture industry directly affects the human health and need in comparison to any other industry. Thus agricultural industry can introduce such contaminants in human system through food chain and web, via water bodies, soil and the food products. However, being the industry which feeds inhabitants of earth, it also remains the most important industry to all mankind. One of the major agricultural contaminant of soil and water bodies is synthetic pesticides routinely used in agricultural practices to enhance the productivity. They can have their health hazardous effect on humans ranging from throat and lung problem, irritation in eyes and even death depending upon the exposure time and quantity.
