The physical characteristics, microbial activities and kinetic properties of the granular sludge biomass were investigated under the influence of different hydraulic retention times (HRT) along with the performance of the system in removal of color and COD of synthetic textile wastewater. The study was conducted in a column reactor operated according to a sequential batch reactor with a sequenc...

Anaerobic digestion can be used to degrade food waste and recover energy. Methane is a biogas that can be efficiently converted in electricity. Organic loading rate, temperature, time, pH, carbon to nitrogen ratio are important factors to be operated in the bioreactors and still are challenges in this process to increase biogas production. It has been reviewed the single phase and two-stage bio...

A study has been conducted to investigate the effect of loading rates on membrane fouling in a moving bed biofilm membrane reactor process for municipal wastewater treatment, especially analysing the fate of submicron colloidal particles and their influence on membrane fouling. Two operating conditions defined as low and high organic loading rates were tested where the development and fate of t...

The UASB Reactor concept represents a very promising proposition for the anaerobic treatment of a variety of industrial wastes and even of domestic wastes. In the present study, after careful acclimatization, the granules were found to be well adapted to fish processing effluent and the COD reduction was upto 96% at organic loading rates from 150 mg l–1 d–1 to 2,200 mg l–1 d-1. The biogas produ...

Anaerobic digestion for biomethane production is an important tool regarding sustainable energy production. The objective of this study was to investigate the effects substrate composition and operating parameters on during anaerobic digestion, focusing use flotates slaughterhouse waste as substrates with a high organic content. A novelty here moving bed biofilm reactor (MBBR) circulation pump ...

The anaerobic digestion of sewage sludge in South Korean wastewater treatment plants is affected by seasonal factors and other influences, resulting lower efficiency gas production, which cannot reach optimal yields. aim this study was to improve the production a plant (WWTP) using data mining techniques adjust operational parameters. Through experimental obtained from WWTP Daegu City, Korea, a...

Oral lichen planus (OLP) and oral lichenoid reaction (OLR) are clinically and histopathologically similar diseases. Whereas OLP is a consequence of T cell mediated autoinflammatory process to a still unknown antigen, OLR might be caused by drugs, dental restorative materials and dental plaque. Pubmed was searched and 24 publications published over the last three years regarding etiology, diagno...

feasibility of methanolic wastes treatment containing chlorophenol in experimental uasb reactors i.e. r-i and r-ii working side by side constantly for a couple of almost 32 weeks were studied. uasb reactor r-i was initiated by utilizing the digested sludge alone, whereas, the uasb reactor r-ii was startedup by adding an activated carbon of an effective size 1.5-2.5mm to the digested sludge with...
