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.

Submersible pump solution for Kenyan water
A water services provider in Kenya's coast province has installed a new set of vertical multistage pumps at its water treatment plant following a failure. Mawasco, based in Malindi, Kenya, procured a set of Poldap Dalgic Pump sets from Konya in Turkey as replacements. Shem Oirere tells the story.
Calculating pipes and duty points with Vogel Software tools
Energy savings can be obtained in several ways, but before manufacturers turn to hydraulic optimisation of units or apply new electrical drives or powerful control systems, they should look at the dimensions of the pipelines and make sure they get the duty point specifications right. This can be done with the aid of web-based tools from Vogel Software.
Drinking water: Ensuring the future of US drinking water supplies
The future availability and quality of drinking water are undoubtedly pressing issues for the US government, as predictions of climate change point to increasing pressures on procurement and supply. Norrie Hunter investigates what the US national and local governments, together with the US EPA are doing to ensure the volume and integrity of the nation's drinking water is maintained and improved.
