Opportunities for rotating belt filters in novel wastewater treatment plant configurations

Dairy Wastewater Treatment using Three-Stage Rotating Biological Contactor (NRBC)

Dairy wastewater is enriched in organic matter (about 45-72 g/l, COD) and also contains biodegradable carbohydrates. A three-stage system, NRBC was fabricated as a bench scale unit for lab experiments, to remove organic carbon from the whey. The fabricated NRBC had several advantages, such as quick start-up, high biomass concentration and was additionally able to handle high organic loading rat...

Electrical Energy Management in Industrial Wastewater Treatment Plant

In this study, the energy consumption of Nasirabad Industrial Park (NIP) treatment plant was evaluated. A combination of up-flow anaerobic baffled reactor (UABR) and aerobic integrated fixed-bed activated sludge (IFAS) processes were employed in NIP. To find out the average electrical energy use per m3 influent wastewater, the rate of energy usage of the plant was calculated by data ...

Positively charged filters for virus recovery from wastewater treatment plant effluents.

Positively charged Zeta Plus filters were used to concentrate enteroviruses from 19 liters of effluent from activated sludge units. Neither the addition of salts nor the acidification of the effluent was required for adsorption of viruses to the filters. Viruses adsorbed to the filters were eluted by treating the filters with a solution of 4 M urea buffered at pH 9 with 0.05 M lysine. Eluted vi...

Efficiency of electrical coagulation process using aluminum electrodes for municipal wastewater treatment: a case study at Karaj wastewater treatment plant

Background: The reuse of treated municipal wastewater is an important source of water for different ,purposes. This study evaluated the efficiency of the electrocoagulation process in removing turbidity,a total suspended solids (TSS), chemical oxygen demand (COD), nitrate, and phosphate from wastewater at the treatment facility in Karaj, Iran. Methods: This experimental study was performed at ...
