Application of effective orifice jet length for treating SST effluent of STP by hydrodynamic cavitation.

Advanced oxidation process in general and hydrodynamic cavitation, in particular, has emerged as a promising technology for the treatment of wastewater in the last few years as the process is energy-efficient and cost-effective. In this process, cavities are generated due to local pressure drops caused by constrictions. This work aimed to investigate the potential of hydrodynamic cavitation as a tertiary treatment to treat the secondary sedimentation tank effluent of a sewage treatment plant, with two laboratory-scale experimental setups having an orifice plate of a 1 mm diameter hole.

Microalgae based wastewater treatment: a shifting paradigm for the developing nations.

Decreased water quality in freshwater resources due to untreated or partially treated wastewater disposal resulting in eutrophication has led to water scarcity. Hence, the present work was aimed to determine the effectiveness of for municipal wastewater treatment in terms of various physico-chemical parameters and nutrient removal. Primary treated effluent was collected from a sewage treatment plant as an influent for the study.

Sustainable treatment of domestic wastewater through microalgae.

The present work evaluated the optimum concentration of microalgal cells for domestic wastewater treatment in terms of removal in nutrients and physicochemical parameters. In the study, three different concentrations (20, 30, and 40%) of microalgae was considered at 8 hours and 24 hours of Hydraulic Retention time (HRT). Among the different microalgal concentrations studied 30% microalgae concentration gave maximum removal at both the HRTs.

A small-scale study of plant orientation in treatment performance of vertical flow constructed wetland in continuous flow.

In constructed wetland (CW) ecology, plants play a vital role in wastewater treatment. The plants provide an adequate surface to various microorganisms, transfers oxygen and uptake nutrients to treat wastewater. This study deals with the treatment of greywater by using vertical flow constructed wetland system (VFCW).

Sustainability and performance analysis of constructed wetland for treatment of greywater in batch process.

In the current scenario, there is a rising interest in the treatment of greywater to be used for non-potable purposes. However, there is a need to understand the role of plants in the treatment process. In this context, this paper addresses the comparison of the treatment efficiency of planted systems with the unplanted system.
