Waste lagoons move into the environmental risk management spotlight
12 March, 2013Underperforming open industrial wastewater treatment lagoons are on the way out, according to an anaerobic technology advocate, as industry counts the cost of its pollution, odours, leakage, energy wastage and relative inefficiency in fixing the problems it set out to address.
Wastewater treatment technique protects fish from antidepressants
11 March, 2013Researchers at KTH Royal Institute of Technology in Stockholm have developed a new technique to prevent pharmaceutical residues from entering waterways and harming wildlife.

Anaerobic technologies cleanly transform wastewater into green energy
20 November, 2012Anaerobic wastewater digestion technologies respond not only to industry’s need to thoroughly clean up the wastewater it discharges to the environment, but also to the need for industry to break free from the cost and pollution of fossil fuels.
Mechanical pre-treatment for membrane plants
20 November, 2012 by Stefan Reber and Christian Frommann Huber, GermanyThe introduction of membrane technology solutions for the treatment of municipal wastewater fundamentally changed the requirements on mechanical wastewater treatment systems. Conventional screening systems with bar spacings or perforations from 6 mm were not sufficient to guarantee the stable and low-maintenance operation of downstream membrane plants.This extract article describes the history of fine screens as pre-treatment systems for membrane plants, with particular emphasis on the importance and influence of operational experience.
