Industrialization has become more essential for economic growth and employment generation in Bangladesh in the last few decades. But the speeding up of the process of industrialization without adequate waste management and treatment facilities have become the cause of degradation of environment and quality of life. The Buriganga, the Dhaleswari, the Lakhya and the Balu rivers have become highly contaminated due to their location in the industrial clusters as untreated wastes have been disposed indiscriminately beyond their assimilation capacity in the recent years. The objectives of this research work are characterizing the effluents of fertilizer factories, estimating the discharged water pollution load, analyzing water quality of the Lakhya River to assess the impact of fertilizer factories effluent and finally recommending interventions to minimize the adverse impact. The study will help in formulation of policy for minimizing the surface water pollution contributed by the fertilizer factories.

Study aimed to treat wastewater by ultrasonic bath at 25, 35 and 130 kHz by estimating biological, physical and chemical parameters. Ultrasound (US), nanoparticle (NP) or in combination (US + NP) may offer an attractive proposition in the area of water purification. The basic phenomena of US irradiation is that acoustic cavitation can affect a number of mechanical, acoustic, chemical and biological changes in wastewater. Such changes occur due to US or NP by generation of free radicals. Owing to US and NP treatment, the enhance level of ROS may generate in water samples, and disrupt the bacterial cell. Present study is focused on US treatment but for better understanding, NP studies were also done in combination. Observations showed that the combined effect of US + NP, treatment alone with ultrasound or nanoparticle are very effective than other treatment processes. Also the ultrasonication of sludge sample is more effective with increasing time and frequency. Most of the research, either in laboratory or full-scale studies showed that US significantly improved the aerobic and anaerobic digestibility. A futuristic approach of US, UV & NP for wastewater treatment is also established

This project was initiated in response to the establishment of mercury TMDLs around the country and issues raised by this process, specifically concerning the issue of mercury bioavailability. While many of these studies recognize that point sources constitute a small fraction of the mercury load to a water body, a question has been raised concerning the relative bioavailability of mercury coming from various sources. For instance, is the mercury discharged from a wastewater treatment plant more or less bioavailable than mercury in precipitation, mercury in urban stormwater, or mercury in sediments? This project seeks to address this question by developing a reliable definition and approach to estimating bioavailability, by profiling various sources of mercury in a watershed with regard to the species of mercury present and by profiling those factors or conditions in either the effluent or the receiving water that enhance or mitigate the bioavailability of those forms. There were several important objectives relevant to the estimation of bioavailability and potential bioaccumulation of mercury from wastewater treatment plants and other sources in receiving waters. The first was to develop a working definition of bioavailability. For purposes of this project, this definition includes not only methylmercury, the form of mercury that readily bioaccumulates in aquatic food chains, but also bioavailable and potentially bioavailable inorganic mercury species that can be converted to methylmercury within a reasonable time frame. It is concluded that the strength of binding to solids and mercury-sulfur-organic matter associations are major factors in determining the bioavailability of inorganic Hg. A second major objective was to identify those factors or conditions in both the effluent and the receiving waters that enhance or mitigate the transformation of inorganic mercury to methylmercury and its subsequent bioaccumulation. Profiles were developed for various sources of mercury in watersheds, including wastewater treatment plants, with regard to bioavailable and potentially bioavailable mercury, and key factors in effluents and receiving waters that enhance or mitigate it. A procedure to assess the relative bioavailability of mercury from various watershed sources, including wastewater treatment plants was developed and tested using data from a US location. The project also features a literature review of conventional and emerging technologies for the removal of mercury from effluent streams and their effects on mercury bioavailability. A review of the salient aspects of mercury TMDLs completed by EPA and the states is also included. This project concludes that, based on available data and bioavailability as defined in this report, wastewater effluent is one of the lowest among the sources evaluated with respect to mercury bioavailability, along with urban runoff and mining runoff. Atmospheric deposition and contaminated sediments tend to be among the highest sources with respect to mercury bioavailability.
