Southern water to increase investment in ‘green’ power
Southern Water has pledged to utilise low-carbon technologies and sustainable best practices to improve water supplies.
Eighteen years old, and still pumping
Like the human heart, pumps in industrial processes do not really do anything specifically interesting. But without them no other process could work properly. If you run an internet search on effluent treatment or primary sludge, you can find lots of sites describing the processes. But, says Toby Clarke, none of them describe the pumps that are used to move materials between each process stage
Disposal route protection, bioenergy production and increased volatile matter conversion are the new market drivers for sludge treatment in the UK. Aidan Cumiskey and Dorian Harrison of Monsal explore some of the issues when considering investment in the new generation of technologies
France extends Europe’s largest WWTP
Europe's largest and oldest wastewater treatment plant, the Seine Aval near Paris, was failing to meet new European discharge standards. Natasha Wiseman reports on the construction of a new nitrification-denitrification unit, using Biostyr technology from French engineering group OTV France (Veolia Water), which will remove the nitrogen contained in the effluent passing through the plant and improve the quality of water returned to the river Seine
Treat less, treat faster – a Seine decision
The Seine Aval wastewater treatment works near Paris is claimed to be the world's second largest. With the help of OTV France (VeoliaWater) and to improve the quality of water returned to the River Seine, the plant is adding a new nitrification-denitrification facility to remove nitrogen from effluent.
Thermal dried sludge meets EU standards
Efficient sludge management is facing the twin challenges of more stringent land disposal regulations and an increase in the quanity of wastewater. Doris Thamer, senior sales manager, and Werner Jenewein, senior process manager, of Austrian sludge specialist Andritz claim that drying technologies can meet both these demands.
Rebuild for world’s largest underground WWTP
Plans to expand residential, commercial and business faciliites near to the world's largest underground wastewater treatment plant in Stockholm, Sweden, necessitated rebuilding the plant. Johnny Stohne, senior engineer for SWECO, reports on the £30 million project, which includes new mechanical treatment, transportation and ventilation facilities.
