The study was undertaken to examine feasibility of biological treating of landfill leachate in anaerobic submerged membrane bioreactor. The aim of the work was to estimate the optimal concentration of leachate in the reactor influent and process... estimate the optimal concentration of leachate in the reactor influent and process parameters on the base of anaerobic digestion efficiency. The treatment efficiency under different feeding condition of leachate dilution in the range of 5–75% (v/v) with a synthetic wastewater was studied. A highe ...

The comparative performance of three pilot-scale anaerobic sequencing batch reactors treating domestic sewage from the University of Sao Paulo (Sao Carlos City, Brazil) was evaluated. Physical, chemical... geometric characteristics (ratio L-length/D-diameter) and mixing type (mechanical mixer or liquor recirculation) and were designed for the treatment of 1.95 m3.d!1 of domestic sewage. The reactors were operated at 8-h sequential batch cycles during 70 days (loading rate: 0.6–1.2 kgCOD.m-3. ...

To remove soluble organics on the other hand, although both chemical oxidation processes and biological treatment such as aerobic systems; anaerobic technologies or a combination of both anaerobic and aerobic processes can be applied, biotreatment overcomes chemical oxidation due to economi ...

Wastewater from olive mills in Jordan has been characterized and treated using a lab scale anaerobic sequencing batch reactor (ASBR). It was found that this wastewater has an average COD:N:P ratio of about 900:5:1.7. At this ratio, the wastewater... wastewater was found to have sufficient nutrients that it was not necessary to add nutrients or combine it with other wastewaters. For effective treatment it was necessary to reduce the strength of the wastewater with an average COD value of about 97 g/L, to about 16 g/L by keeping part of th ...

A carrier anaerobic baffled reactor (CABR), containing hollow-sphere bamboo carriers, was used to examine the effects of organic and temperature shock loads for a... first chamber. Therefore, the CABR had high shock resistance and adaptability irrespective of temperature and feed strength.

... of water quality by constructed wetland systems is increasingly practiced world wide. The use of a treatment train consisting of an up-flow anaerobic sludge blanket (USAB) reactor followed by free water surface and subsurface flow constructed wetlands in series has been investigated. The commo ...
