Almost a third of Earth’s freshwater resources are used by municipalities, agriculture and industries therefore very large quantities wastewater generated discharged into surface water or groundwater. If inadequately without previous treatment, can cause chemical pollution, affect aquatic life as well human health have negative impact on the environment. An emerging technology for treatment is ...

wastewater treatment and re-use of industrial process water are critical issues for the developmentof human activities and environment conservation. the present study was undertaken to evaluate the degradationof organic pollutants taking phenol as the model compound over aluminium pillared montmorillonite and therare earth exchanged analogues, underlining the use of environ friendly clay cataly...

Cork boiling wastewater pollutants were fractionated by sequential use of four ultrafiltration membranes and five fractions were obtained: four retentates (>100, 50-100, 20-50 and 10-20 kDa) and one permeate (<10 kDa); which were used to study the correlation of molecular size with biodegradability and toxicity before and after ozonation. The results show that molecular size is correlated with ...

OBJECTIVES To evaluate the merit of a new alginate efficacy film test to determine the bactericidal activity of the high-level disinfectant ortho-phthalaldehyde (OPA). METHODS The efficacy of OPA was investigated using a new sodium alginate surface film test against Mycobacterium chelonae NCIMB 1474 and Epping, and Pseudomonas aeruginosa NCIMB 10421 under different test conditions. RESULTS ...

Petroleum refineries discharged large amount of wastewater -during the refining processthat contains hazardous constituents that is hard to degrade. Anaerobic treatment process is well known as an efficient method to degrade high strength wastewaters. Up-flow Anaerobic Sludge Blanker (UASB) is a common process used for various wastewater treatments. Two UASB reactors were set up and operated in...

With rising environmental concerns on potable water safety and eutrophication, increased media attention and tighter environmental regulations, managing animal waste in an environmentally responsible and economically feasible way can be a challenge. In this study, the possibility of using granular anammox process for ammonia removal from swine waste treatment water was investigated. A rapid dec...
