These systems have been turned out to be effective in treating expansive volume of textile industry effluents.The proponent also established an Environmental Health and Safety Unit.This included a laboratory for conducting environmental management activities related to operating the ETP, and collecting, testing, and disposing of solid and liquid wastes.
It was noted by way of observation that the project proponent had put due efforts into managing contaminated waste released by the power plant. The treated waste is collected and disposed of by the contractors as approved by the DOE. Despite the satisfactory arrangement for the management of solid and liquid wastes, the informants, however, expressed their concerns that the waste management activities undertaken by the proponent should be closely and regularly monitored and verified by the DOE. In the absence of the DOEs regular monitoring, the project proponent may not operate ETP at all and release toxic waste into the river water. This is a common phenomenon in Bangladesh where industries often tend to release toxic waste without treatment. Effluent Treatment Plant Process Trial Proponents TendTherefore, particularly during the rainy or flood seasons, many industrial proponents tend to discharge the effluents directly into water without any treatment. The researchers observed that this concern was compounded among the community people surrounding the MPPP. ![]() Effluent Treatment Plant Process Full Chapter URLView chapter Purchase book Read full chapter URL: Bioremediation of dyes from textile and dye manufacturing industry effluent Razia Khan. Zeenat Khan, in Abatement of Environmental Pollutants, 2020 11 Conclusion and suggestions The aim of the effluent treatment plants in the textile and dye manufacturing industrial clusters is to actualize innovations giving minimum or negligible water contamination. These effluent treatment units in the textile and dye manufacturing industrial clusters are the most acknowledged methodologies toward achieving environmental safety. In any case, sadly, no particular treatment approachtechnique is suitable or all around appropriate for a wide range of textile and dye manufacturing industry effluents. Along these lines, the treatmentremediation of textile and dye manufacturing industry effluent is performed by combining several methods or techniques, which contain physical, chemical, and biological frameworks relying on the sort and quantum of contamination load and contaminants included. In this section we have examined a few methodologies that can be adjusted to treat the dye in textile and dye manufacturing industry effluents and to decrease the pollution load. Physical and oxidation strategies are compelling for the removal of dye compounds in dye-containing effluents only if the colored effluent volume is small. Cost of utilization of membrane filtration confines its utilization in large-scale treatment. Effluent treatment plants using biological treatment approaches, instead of chemical methods, guarantee that their inclination is because of low generation of inorganic sludge, low expenses, and complete mineralization of dye compounds in the biological method. By and large, textile and dye manufacturing industry effluents after biological treatment are not in consistence with the wastewater release standards. So as to meet effluent release standards and to lessen the impact of harmful or inhibitory substances on microorganisms, initially, recalcitrant compounds and dye compounds ought to be oxidized by chemical oxidation or advanced oxidation technique to change over it to biodegradable constituents previously exposing the wastewater to bacterial treatment is favored. Cavitation can be utilized to obliterate microbial life in water assuming any. The treated water after removal of microorganisms can be reused for cleaning purpose. Uses of eco-friendly and cost-effective frameworks, for example, constructed wetlands for the treatment of dye-containing industrial effluents, have been all around examined.
