The lakes of India are getting significantly polluted due to the rapid growth industries, plastics, and anthropogenic waste. Due non-functioning industries human activities during COVID-19 pandemic lockdown, industrial other waste going was reduced. Moreover, with reduction tourism in cities lakes, pollution also Turbidity is key indicator water lakes. It has a direct relationship surface refle...

hospital wastewater has special importance since having pathogens, radioactive materials, pharmaceutical wastes and heavy metals. removing them into environment without any treatment may cause serious problems for the public health. membrane biological reactor is the combination of the activated sludge and membrane filters. this research has investigated the performance of the nano-filtration i...

From studies on 11 different proteins (including native albumin and albumin with reduced disulfide-bridges) treated with sulfosalicylic, 2-naphthalenesulfonic, toluenesulfonic, dichloroacetic, or trichloroacetic acids, we elucidate the interactions determining the resulting turbidities and other factors affecting turbidities, and we discuss the clinical utility of such turbidimetry. At least th...

The objectives of this research work was to evaluate the reduction of THM precursors by cationic pDADMAC and determine the correlations between the chlorine demand and trihalomethane formation in the presence of electrolyte solutions and ambient light. The chlorine demand was found to be significantly reduced provided that the H2SO 4 electrolyte was fed to the sample solutions. The amount of CH...

This study presents results of the photocatalytic inactivation of two groups of microorganisms: spores of the anaerobic bacterium Clostridium perfringens and coliphage. A cylindrical reactor impregnated with titanium dioxide and irradiated with ultraviolet light (15 W) was used. Parameters such as color, turbidity, hydraulic detention time (HDT) and initial concentration of microorganisms were ...

background: electrocoagulation is a technique involving the electrolytic addition of coagulating metal ions directly from sacrificial electrodes. these ions coagulate with turbidity agents in the water, in a similar manner to the addition of coagulating chemicals such as alum and ferric chloride, and allow the easier removal of the pollutants. purpose of this study was to conduct experimental i...

Water disinfection is a vital control-point to minimize transmission of diverse pathogens from water sources or produce within and among lots at harvest, during initial postharvest handling, and within subsequent postharvest re-packing and processing. The use of ClO2 as an alternative to NaClO for water disinfection is being adopted by the fresh tomato postharvest handling industry. Lack of dat...

background: contamination of swimming pools’ water can lead to the transfer of different diseases to humans. the aim of this study was to investigate the quality of water in kerman swimming pools. methods: in this cross-sectional study, sampling from swimming pools was performed before and after swimming, every week. total number of samples collected was 150 samples. samples were investigated i...

The wastewater generated by the textile industry is rated as the most polluting among all industrial sectors considering both volumes discharged and effluent composition. Present investigation intended for COD and color removal from textile wastewater using naturally prepared coagulants i.e. Surjana Seed Powder (SSP), Maize Seed Powder (MSP) and Chitosan. Effect of coagulant dose, flocculation ...

Article history: Received 30 August 2017 Accepted 18 September 2017 Available online 02 October 2017 The textile industry is a field which has strong environmental impacts due its high consumption of water and emission of pollutants, specially the dyes. The dyes are organic or synthetic substances which alter the physicochemical characteristics of the water body in which they are released, incr...
