Control of acid mine drainage using flue gas desulfurisation sludge cap with coal combustion residues
The long-term physical and chemical effects of using coal-combustion residues (CCRs), in particular fixated flue gas desulfurisation (FGD) sludge, have been monitored as a major component in the reclamation of a pyritic refuse deposit. This was undertaken to determine the consequences of placing these controversial materials in an unrestricted environment.
Effects of anthropogenic inputs on organic quality of urbanised streams
Dissolved organic carbon is examined in streams with varying anthropogenic influences, using a technique to determine organic quality with and without upstream wastewater treatment plant inputs. Effluent-derived organics can persist for a long way downstream of discharge points.
Radioactive wastewater purification using titanosilicate materials
This study reviews the literature on the uptake of radiocations on titanosilicate materials, in particular the influence of physicochemical parameters on uptake. The use of titanosilicates is found to be beneficial as cleaning agents for radioactive effluents.
Replacement predictions for drinking water networks through historical data
This study uses historical data from more than 100 years to predict the future replacement needs for drinking water distribution networks. The historical data provide a reliable prediction, and the data fit well with commonly used lifetime distribution curves.
Possible impacts of floods and droughts on water quality
This paper reviews changes in water quality, with all its consequences, during selected recent extreme hydrological situations in the Czech Republic.

Maintaining deep well submersibles
Maintenance of submersible pumps is complex due to the depth at which they are installed, which makes access difficult. Correct facility design to extend the time between failures and the monitoring of several parameters to determine the pumps’ performance during operation are therefore vital factors, as Miguel Ortiz from FACSA and Alejandro Palomo from Salinas y Perez report.

Paris fountains get a new lease of life with KSB
When the fountains in the Trocadero Gardens near the Eiffel Tower in Paris needed extensive renovation work, it was not only a question of what equipment to choose but also how to get it through very restricted access routes. KSB's solution was to dismantle and then rebuild the machines powering the fountains in situ.

Energy optimization for Grundfos booster sets
C. Kallesøe, J. Aarestrup and K. Rokkjær of Grundfos analyse the control and design of booster sets from an energy perspective. They investigate how the structure and control can be used to minimize energy consumption, and demonstrate that equally sized pumps equipped with speed control and running at the same speed are a safe design choice.
Surge protection in tall buildings
As water companies reduce water pressure in the domestic mains to reduce leakages, tall buildings are becoming reliant on booster pumps to provide water at sufficient pressure to enable normal daily living. This has revealed a potential threat – hydraulic shock, says Gary Wheatley from Wilo (U.K.) Ltd.
