Sentence examples for of sludge production from inspiring English sources

Previous studies already demonstrated that titanium salts not only provide a cost-effective alternative to conventional coagulants by producing a valuable by-product but also minimise the environmental impact of sludge production.

A mass balance for DEHP was calculated using data from field studies and estimates of sludge production at the works.

An integrated methodology is recommended involving the application of ion exchange resins that recover dissolved iron without the need of sludge production.

Although the reduction of sludge production happens by adding degradation-resistant materials and toxicants, reduction of pollutants to an acceptable value in effluent is necessary due to environmental standards.

Increased attention has been given to minimization of sludge production from activated sludge process since environmental regulations are being more and more stringent in relation to excess sludge disposal.

The MBR has several advantages such as complete removal of suspended solids, compact plant size, high rate of degradation, flexibility in operation, low rate of sludge production, disinfection and odour control, prolonged microorganisms retention time and treatment of recalcitrant and toxic organic and inorganic pollutants.

In other words, if the problem of excess sludge production is solved, most of the problems would also be solved considerably in the treatment and disposal of the biomass [7, 8].

The reason of decreasing sludge production coefficient was energy spilling because of uncoupled para- nitrophenol in the reactor as the result of less electron transportation from electron donor [42].

Thus, these early results indicate that even with weakly loaded systems, a MFC system has great potential as a wastewater treatment process since organic loadings of COD can be easily converted into electricity with a concomitant reduction of excess sludge production.

The results imply that reduction of excess sludge production is due to uncoupled metabolism at low TCS dosage, but microbial death at high TCS dosage.

This paper, therefore, reviews strategies developed for minimization of excess sludge production, such as oxic-settling-anaerobic process, high dissolved oxygen process, uncoupler-containing activated sludge process, ozonation-combined activated sludge process, control of sludge retention time and biodegradation of sludge in membrane-assisted reactor.
