The results of experiments on municipal wastewater primary effluent are presented for a pilot-scale submerged membrane bioreactor (SMBR). The SMBR pilot plant employed an ultrafiltration membrane with a nominal pore size of 0.035 microm and was operated at a constant membrane flux of 30 L/m(2)h. The mixed liquor suspended solids (MLSS) concentration was maintained at 8+/-2 g/L and steady-state ...

This work provides insights on the solubilization products after a simultaneous combination of alkaline and ultrasonic (ALK+ULS) pre-treatment of sewage sludge. Soluble chemical oxygen demand (SCOD) increased from 1200 to 11,000 mg/L after such treatment. Organics with molecular weight around 5.6 kDa were solubilized because of the synergistic effect of ultrasound and alkali. Organics with mole...

Scarcity of water resource recommended developing innovative technology to reclaim wastewater. Greywater is an appropriate source reuse through advanced treatment. Meanwhile, MBRs are novel techniques wastewater, which composed activated sludge processes and membrane filtration. Characteristic application Hybrid MBR, MBMBR OMBR were reviewed in this article. And sources, analysis methods contro...

A small molecule derived from a marine natural product with the ability to inhibit biofilm formation and also disperse established proteobacterial biofilms is presented.

Synergistic microbial communities are ubiquitous in nature and exhibit appealing features, such as sophisticated metabolic capabilities and robustness. This has inspired fast-growing interest in engineering synthetic microbial consortia for biotechnology development. However, there are relatively few reports of their use in real-world applications, and achieving population stability and regulat...
