Coal mining activities generates huge amount of effluent containing various pollutants. These pollutants are discharged into surrounding water body, thereby polluting it. Major pollutants from coal mining effluents are total suspended solids (TSS), total dissolved solids (TDS), hardness, heavy metals (Fe, Cr, Cd, Cu, Ni, Mn), sulphates, nitrates, phosphates, oil and grease, chloride. When discharged into the aquatic ecosystem, it affects the system. The effects can be also observed by measuring biological properties of aquatic ecosystem. Bina open cast coal mine discharges its effluent to the GBP Sagar. Which was found contaminated with different pollutant. For the waste water management two technologies were used, in first methodology biological treatment of heavy metals using aquatic macrophytes was performed. Different species were tested for their pollution removal capacities and it was shown that they can be used for water pollution management in coal mine area. Second methodology was chemical treatment of suspended solids by the use of coagulants like lime, alum and true floc .
Hospital wastewater is a reservoir of potentially harmful microorganisms. The discharge of hospital effluent directly into the municipal sewerage system or into the river without treatment could be hazardous to human health and receiving environment (water, soil and air). Randomly, triplicate hospital effluent samples at two sampling points from each 10 hospitals of Kathmandu were selected to determine bacterial load and presence of antibiotic and disinfectant resistant solates.The study showed occurrence of high bacterial load (both heterotrophic bacteria and coliform count) in all the hospital effluents under investigation, indicating high levels of pollution as safe discharge of such wastewater category should not exceed 100 CFU/ml for (TVB), 30 CFU/ml for (TC) according to the EPA Guidelines.Most of the isolates were found to be MDR.Disinfectant resistant organisms were also observed in the hospital effluent sample.Untreated liquid waste disposal into surface water directly or indirectly, has huge number effects including the addition of pathogenic microorganism, multiple drug resistance bacteria, disinfectant resistance bacteria and resistant gene in the environment.
Phosphate is an important resource for modern agriculture and food supply. But phosphate released into water bodies can lead to eutrophication. Therefore, a major focus in wastewater treatment is the removal of phosphate. This is currently done with a focus on phosphate elimination rather than recovery. As microalgae can take up phosphorus at high rates and can subsequently be used for valuable products such as biofuel and fertilisers, their potential for alternative wastewater treatment needs to be evaluated. In this thesis, the two microalgae species Chlorella vulgaris and Scenedesmus obliquus were tested in respect to growth and phosphate uptake performance in different wastewaters. Also, the effect of glycerol as an organic carbon source to overcome light limitation with mixotrophic growth was tested. Additionally, a lab-scale rotating algae biofilm reactor was developed and tested with secondary wastewater effluent and a hydraulic retention time of 5 days.
Shorttitle:Treated wastewater may be reused for different purposes such as landscape irrigation, industrial uses, groundwater recharge or in agricultural use. Reusing effluent for irrigation can be the best way to utilize the wastewater since it removes many of the nutrients that are not removed with primary and secondary treatment processes. The feasibility of wastewater reuse ultimately depends on the cost of reclaimed wastewater relative to alternative supplies of water, and on public acceptance of the reclaimed wastewater. For social efficiency, every wastewater treatment decision must balance many variables and find the combination with greatest net benefit. This report presents an assessment of the viability of wastewater reuse in agriculture taking a commune in Cambodia as a case study. Following the definition of general guidelines for wastewater reuse for irrigation, the assessment examines the main challenges for developing water reuse, with emphasis on the choice of treatment method, economics, water quality issues, and social value of recycled water. The study showed that the utilization of treated effluent in irrigation is profitable for some crops.
Pollution is increasing throughout the world in different ways, mostly by inhuman activities, creating problems to the entire living creature. Sago is an edible starch produced from tapioca, a tuberous root, though the indigenous technology in most of the countries of the world. During the process, huge amount of water is required and released as an effluent with increased toxicity and low pH, which pollutes the water bodies nearby and the land where it is thrown. This effluent decreased the pH of the soil which is not fit for cultivation. On the other hand, lignite fly-ash is a deadly air pollutant with high alkalinity (Indian). In our study, the effluent has been treated with a definite amount of lignite fly-ash and used for the culture of black gram at different concentrations. Also the effluent has been treated with some acids and the results have been evaluated, showing that acid treated cum fly-ash neutralized effluent is more efficient for the culture of black gram. The lignite fly-ash treatment of sago factory effluent seems to be cost effective and eco-friendly. So, I am hopeful that interested students and researchers may get the insight from the published research work.
Many water demands such as industrial, agriculture can be satisfied with water of less than potable water quality. The use of reclaimed water for non-potable purposes offers the potential for exploiting a new resource that can be substituted for the existing sources. By replacing the potable water used for non-potable purposes an increased population can be served for the existing source. The greatest benefit of urban reuse systems could be their contribution in delaying or eliminating need to expand potable water supply and treatment facilities. The usual constraints are lack of financial resources, absence of indigenous technology, and absence of trained manpower and lack of motivation for environmental protection. The major aim of the proposed work was to examine the effects of dairy effluent on Brinjal or eggplant (Solanum melongena), onion plant (Allium cepa) and Tomato plant (Lycopersicum esculentum).
