The uncontrolled discharge of organic and inorganic substances causes overenrichment of water bodies by nutrients resulting in eutrophication which disturbs the flora and fauna balance of the lake ecosystem affecting its water quality. Therefore, it is necessary to remove excess nutrients from contaminated lake water. The present investigation was...

Rapid development of the industrial and domestic sectors has led to the rise of several energy and environmental issues. In accordance with sustainable development and waste minimization issues, biohydrogen production along with biomethane production via two-stage fermentation process using microorganisms from renewable sources has received conside...

The excessive utilization of fossil fuels consequently causes global climate change because of the emission of greenhouse pollutants. Hence, hydrogen is considered as the major energy carrier in the future because of its high conversion capability, recyclability and non-polluting nature. The present study focuses on the enhancement of fermentative...

Microalgae cultivation using organic wastewater like kitchen wastewater (KWW) and sewage wastewater (SWW) are recommended for wastewater treatment along with simultaneous biomass production which is a cost effective strategy. KWW is rich in nutrients which might be an efficient wastewater feedstock for microalgae cultivation to achieve reasonably h...

The upsurge in the concerning issues like global warming, environmental pollution and depletion of fossil fuel resources led to the thrust on third generation biofuels. Algal research has gained a lot of importance in the recent years. Effective utilization of algal biomass in a single step is necessary as it can produce Bio-oil (BO), gases and in...

Phycoremediation or microalgae cultivation using sewage with industrial flue gases is a promising concept for integrated nutrient removal and sequestration respectively with subsequent biomass generation in order to control environmental pollution. In the present study sewage wastewater (SWW) and industrial flue gas was supplied in batch and contin...

Chlorination has been employed extensively for sewage disinfection so that it can be reused, but the health issues related to its disinfection byproducts (DBPs) have forced to search for safer options. The present study focuses on the efficiency of chlorine disinfection on five dominant coliform bacterial species present in the secondary treated ef...

Ozone is an attractive disinfection alternative to chlorine as chlorine has some environmental consequences due to its disinfection byproducts potential. In the present study ozone was used for the disinfection of secondary treated effluent of sewage treatment plant which is based on rotating biological contactor, process, Malaviya National Institu...

This paper presents a critical review on sewage disinfection process using chlorine, which is shrouded with lot of controversies. The review highlights the general applications and limitations of chlorination of sewage for disinfection including its low efficacy against resistant coliform bacteria that results in excess chlorine dosing. Excessive d...

Chlorination is one of the most widely used methods to disinfect wastewater, despite innumerable objections raised due to the resultant by-products. Any attempt to reduce the dosage of chlorine can be very useful in lowering the concentration of the disinfection by-products, many of which have been reported to be carcinogenic. This study examines t...
