Treatment of pesticide intermediate industrial wastewater using hybrid methodologies

AbstractAbatement of water pollution is being a major concern to be dealt with, as the scarcity of water for basic needs of human beings is increasing drastically. As a part of diminishing water pollution, treatment of industrial wastewater prior to disposal plays a paramount role. Due to the typical characteristics of pesticide, intermediate industrial waste water the treatment is also challenging issue. In this study three different sequential methodologies (Methodology-I: combined rotavapour distillation, fenton and anaerobic biological process, Methodology-II: combined rotavapour distillation, photo fenton and anaerobic biological process, Methodology-III combined coagulation, fenton, electro oxidation and anaerobic biological process) has been evaluated for the treatment of pesticide intermediate industrial wastewater. Among the three sequential methodologies opted in this study for the treatment of pesticide intermediate industrial wastewater, percentage removal of COD was 95% in methodology-1 (i.e. combined rotavapor distillation, fenton and anaerobic biological treatment).

Ozonation Process

While developing the technology of using ozone for the destruction of organic substances in industrial wastewater, it is important to determine the required dose of ozone and the period of water treatment. In some cases, for example, when the dyes are destroyed in textile sewage, the color reduction occurs earlier than the decomposition of the organic matter of the dyes. Thus, there is a need to control the purification process by several indirect indicators, such as oxidability, total organic carbon content and etc. There is also the difficulty in determining the required dose of ozone for the decomposition of contaminants. We carried out experimental researches and examined the material balance of the ozonation process. A generalized method for determining the consumption of ozone in the oxidation of contaminants in sewage waters is proposed. The indicator "chemical demand of ozone" is used. During the trial ozonation of waste water the method allows to obtain the dependence of ozone consumption on the processes of pollution destruction and to determine the required specific dose of ozone for the destruction of contaminants.

The Zarqa River is Jordan's major surface and ground water basin, where most of the industries are located. A summary of an industrial waste water survey is presented, with quantity and quality of the discharges and methods of disposal. Compliance with the effluent standard and the effect on the environment is discussed. It is concluded that there is contamination of surface water and a potential of contamination of ground water, the river bed and soils adjacent to the river. The existing regulation, standard and practices in industrial wastewater management are reviewed and new principles are suggested to be adopted for setting a sustainable policy in wastewater management.

An investigation was made to ascertain heavy metals concentration in effluent samples collected from textile industries located at Bhaluka industrial area, Mymensingh, Bangladesh during August to November, 2013. Atomic absorption spectrometer (AAS) was used to evaluate the concentration of Zinc (Zn), Copper (Cu), Nickel (Ni), Cadmium (Cd), Chromium (Cr) and Lead (Pb) in the samples. The study revealed that heavy metals were present in variable amounts, where the concentrations of Cu (0.0405 ppm) and Pb (0.0003 ppm) were found lower than recommended level for industrial waste water. Among the present trace metals, the highest concentration (0.2-1.0 ppm) was found in Zn. Although the concentration is suitable for irrigation, it is unsafe for aquaculture. Besides, all of the wastewater samples possessed no Cr, Cd and Ni, which comprised less of the minimum acceptance level, indicating no possibility of contamination. However, comparing findings of this study with the safe limits for industrial wastewater, it can be concluded that the waste water of the study area except some sampling sites can be used for irrigation and aquaculture.

Maximum Decrease

As we all know that water is essential to all forms of life and makes up about 70% of the human body weight. Due to the direct link of water quality with human welfare, the quality of water is of vital concern. Industrialization plays major role in the development of a country’s economy. However, these plants and industries generate hazardous by-products and discharge them directly or partially treated into the environment which contaminates the surface water, ground water and soil causing a great threat to the life of human beings, animal and plants. In the present investigation an attempt has been made to identify the potential of water hyacinth (Eichornia crassipus) and Duckweed (Lemna minor) for the treatment of industrial waste water generated from Dehradun industrial area using phytoremediation technology on the basis of different physicochemical parameters such as pH, EC, DO, ORP, Salinity, TDS, BOD, COD, Hardness and Temperature. Eichornia crassipus shows maximum decrease in pH, TDS and COD and Lemna minor shows maximum decrease in EC, ORP, Salinity, BOD and TH. In case of DO maximum decrease was observed in control experiment. During the assessment period Lemna minor was found highly efficient in comparison to Eichornia crassipus. Both water hyacinth (Eichornia crassipus) and Duckweed (Lemna minor) shows maximum removal between 1st to 5th day of treatment but the removal goes down as the experiment proceeds towards the end as the retarded growth of plants was observed due to toxicity of accumulated pollutants inside the palnts.
