Premium Efficiency Wastewater Pumping - Optimising energy consumption and preventing blockages [Dec 2009]
There is no doubt that the pressures on a wastewater business have changed regardless of whether you are a publicly funded municipality, privately owned water company or a private operator of a wastewater collection system. We clearly see an increased focus on energy use with regard to cost and CO2 footprint, along with the demand to reduce the number of blockages and the associated risk of overflows.
Dry Chemical Odour Scrubbers [Sep 2008]
The principle of distributed odour control
Dry chemical scrubbers are uniquely suited for use in collection system pump stations and in waste water treatment plants for the control of odours. They are inherently simple in their operation and function continuously without operator attention for extended periods of time. This type of scrubber, through the use of specialised gas-phase or dry-scrubbing air filtration media types(medias), is essentially able to achieve the complete removal of odours without the need for additional dilution air.
Getting the Measure of Methane [Jan 2008]
Geotech looks at the world of biogas with focus through two case studies
Methane makes money. It generates energy revenues, carbon credits and is part of bio-treatment sludge processing. In most of the world it has only just begun. Measuring what we are doing and being responsible with this potentially damaging greenhouse gas makes good sense.
Sludge and Biosolids Management [Sep 2007]
There is a need for proportionate and consistent approach to regulation
This is the second paper on this series. In the first1 I reviewed a broad breadth of issues related to managing sludge and biosolids including anaerobic digestion, the potential of biogas, drying and land application. This paper will build on, rather than repeat the information in that first paper. Save to say that sludges are an inevitable consequence of treating wastewater and, because the type of wastewater treatment affects their character, consideration should be given to the fate of the sludge at the earliest stage in design of wastewater treatment. Having said that, there are exciting advances and retrofits that will be discussed in this paper.
Filamentous Species and Industrial Wastewater [Sep 2006]
Identification and control of filamentous micro-organisms in industrial wastewater treatment plants
The activated sludge process is widely used for treating domestic as well as industrial wastewater. Excellent treatment results can be obtained in properly designed and operated plants as long as the activated sludge flocs settle well in the final clarifier.

Making Sure We Make the Best Use of Them
The specification and use of online/field instruments and test kits can be a complicated business. Making the wrong choice could prove expensive.
Tim White explores the range of International Standards and related guidance which can help when specifying equipment and validating the data against required performance set by standard methods advocated by regulatory bodies.
