PMS motors deliver cost-effective and greener wastewater treatment
The treatment of water and wastewater is an essential task to protect water resources and reduce our impact on the environment. However, the energy consumed in carrying out such treatment processes also have an impact on the environment; not to mention an impact on the wallet as energy prices continue to rise, as Mark Venables discovers
Pulsar ultrasonics are no slouch to sludge
Wessex Water is reporting success with seven new sludge blanket monitors, from Pulsar Process Measurement, at its Christchurch sewage treatment works.
Pump prediction
Modern non-invasive motor condition monitoring equipment is proving its worth at Wessex Water. Brian Tinham talks to operational services manager Dave Durkin
Pumping challenge
Engineering invariably involves a balancing act - mostly between, on the one hand, keeping within budget, while, on the other, developing robust, dependable solutions that meet parameters, such as design life and risk mitigation.
Lay waste to poor treatment
There are many ways to clean up performance of water and effluent treatment units in industrial plants. Steed Webzell takes a look at some of them
Testing the waters
No one likes being overburdened with regulations, and plant engineers are no exception - fact. However, in a world forced into a rather late, reactionary effort to clean up its act, pollution in the waste water and effluent sector was always going to be fair game, and we have had to adjust to living in a tightly regulated climate where awareness is all.
Hot water systems - Better tanks give quick and clean hot water
Hot water tanks made by a small German company use a patented system to ensure that they deliver hot water soon after heat has been applied to the water. This makes them especially suited to systems fuelled by solar energy.
Legionnaires' disease - are you protected?
As this issue of Plant Engineer goes to press, a design services manager for Barrow Borough Council is facing seven charges of manslaughter over an outbreak of Legionnaires' disease in August 2002. A further 140 people were infected by the disease, which investigators believe was spread by an air-conditioning unit at an arts centre in Barrow-in-Furness.
Liquid assets
Water and waste treatment plants are among the oldest around anywhere, but don't imagine they're bereft of developments. Brian Tinham reports
Babies and bathwater
Plant, equipment, instrumentation and the regulatory frameworks have all been evolving to meet the challenges of pollution and climate change. Brian Tinham examines the issues
