The Problem of APIs
For many years we have seen growing evidence of the deleterious effects of active pharmaceutical ingredients (APIs) in the natural environment. Feminisation of fish, increasing susceptibility to predation and increasing antibiotic resistance have all been linked APIs but the extent of this pollution has never been truly assessed. A new study[i], carried out by a […]

Tackling Active Pharmaceutical Ingredients in Wastewater
The water industry national environment programme (WINEP) is concentrating on catchment and nature-based solutions to prevent pollution of watercourses, and this will work well for “traditional” pollutants like agrichemicals including nitrate fertilisers, herbicides and pesticides. However, there are many other contaminants that cannot be reduced by nature-based solutions and are not removed by conventional wastewater […]

Reducing Sludge Bulking without Chemicals
There are few activated sludge wastewater treatment plants – both municipal and industrial – that haven’t, at some time, suffered from the phenomenon of sludge bulking. This is when sludge refuses to settle and forms a layer of dense brown foam on the surface of the aeration tank and final settling tank. The result of […]

Using Artificial Intelligence to Reduce Carbon Footprint
Over a decade ago, ‘A Low Carbon Water Industry in 20501 ’report was issued by the Environment Agency as part of its Resource Efficiency Programme. It was a response to the Climate Change Act, which imposed a legally binding target of reducing, by 2050, UK greenhouse gas emissions by 80% from their 1990 levels. How […]

Asset Optimisation powered by Createch360
Artificial Intelligence – The Future of the UK Water Industry Most process industries, from oil refining through to pharmaceutical manufacturing, have consistent operating conditions: feedstocks are controlled and production is carefully planned. The water industry’s “feedstock” is whatever comes down the sewer, with huge variations in flow and quality depending on the season, weather and […]

Get your ACT together with accurate UV dosing!
Portsmouth Water’s Westergate WTW treats up to 22Ml/d of water from three boreholes and supplies potable water to Littleheath service reservoir. Originally, disinfection of the water was by super-chlorination and de-chlorination using chlorine and sulphur dioxide respectively. In order to provide protection against the possibility of Cryptosporidium, Portsmouth Water decided to install ultraviolet lamps as […]
