Disposal of tannery effluent will result in heavy metal contamination of land and will lead to many important health and environmental hazards. Aim of the work is to determine the effects of untreated tannery effluent and treated tannery effluent on seed germination and to biodegrade the effluent using fungi. Chemical methods of remove the heavy metals in tannery effluent will have metal bearin...

Coastal sandy soil is characterised by low fertility and poor physical properties. Distillery effluent, a liquid waste from the distillery industry contains large quantities of soluble organic matter and plant nutrients. It does not contain any toxic elements / compounds. In order to improve the physical properties and fertility of the coastal soil by utilising the distillery effluent, field ex...

Membrane biological reactors combine the use of biological processes and membrane technology to treat wastewater. The use of biological treatment can be traced back to the late nineteenth century. It became a standard method of wastewater treatment by the 1930s (Rittmann, 1987). Both aerobic and anaerobic biological treatment methods have been extensively used to treat domestic and industrial w...

Membrane separation is an emerging technology for secondary effluent (SE) recycling as alternative water source. However, SE contains metabolites which form a film on membrane surfaces, leading to decrease in hydraulic capacity. This extensive study of the effect fouling UF performance, with detailed analysis foulants composition and morphology, evaluation most effective – either physical or ch...

In northern coastal industrial park, inlet of the wastewater treatment plant (WWTP) had characteristics low carbon source and high chloride ion concentration, which resulted in its poor biodegradability. this case, experiment explored an electrochemistral method to remove nitrogen. Cathodic potential, Ti/IrO2 was confirmed as anode − 1.6 V taken potential order nitrate-N. The findings include: ...

Wastewater reuse is essential for sustainable water management. However, it requires tertiary treatment within the plant to ensure suitable quality. This project aims investigate comparative performance of conventional (sand filtration) against membrane filtration technology demonstrate viability wastewater reuse. Sand along with two filtrations, Nano Filtration (NF) and Reverse Osmosis (RO), w...

A new sand filtration water disinfection technology is developed which relies on the antimicrobial properties of hydrophobic polycations (N-hexylated polyethylenimine) covalently attached to the sand's surface. The efficacy of the filter disinfection process was evaluated both with water spiked with E. coli and with real aqueous effluent from a wastewater treatment plant. For the former, over 7...
