Embracing change with VeoliaWaterTechnologies UK


FollowingOfwat’s final determinations on the price reviewfor 2019 (PR19), water companies across the UKmust nowmeet tighter phosphorus discharge consents than ever before. Here,Mike Froom, Business DevelopmentDirector at VeoliaWater Technologies UK (VWT UK) examines the potential technologies and services that can help to achieve reliable results. The latest price review(PR19), issued by thewater services regulation authorityOfwat, has caused a great deal of concern formanywater companies. In fact, a record number of related complaints about the financial restraints of the final determinations have beenmade to the Competitions andMarketsAuthority.Whilst companies await appeal decisions, it is important that they begin planning forwhat comes next, should the regulations be upheld. In doing so,water companies are looking at newways to bring innovative, cost-effective working practiceswithin their operations, as well as becomingmore familiarwith the technologies available for phosphorus (P)


their operations. Fortunately, there are a number of innovative solutions,which allow companies to remove P frominfluentwaste water efficiently and effectively.Depending on the individual treatment plant’s


discharge permit,water companies removal. These pressures of the PR19 price reviewaremagnified by


the obligation to alsomeet the targets of the Government’s ambitiousNational Environment Programme (WINEP) by 2025. This programme outlines theGovernment’s expectation £5 billionwill be invested into newmeasures to help boost natural environment protection. In particular,The EnvironmentAgency expects the investment to further protect and improve standards across the country’swaters, shellfish sites, protected nature conservation sites, aswell as making other river and biodiversity enhancements.Despite the positives,many companies remain unsure about the practicality of finding newefficiencieswithin

may need to combine different solutions together to achieve compliant results.Moving forward,water companies looking tomeet discharge permits of>1.0mg/L should look to utilise Enhanced Biological Phosphorus Removal (EBPR) solutionswhere possible. When implemented by awater technologies expert, such asVWTUK, EBPR solutions allow companies to reduce operational costs and chemical sludge levels. Furthermore, the solution can be used to create biogas, aswell as providingmore scope for recycling the waste P than alternative systems. Forwater companies preparing to dealwith even tighter discharge limits, it is oftenmore suitable to combine a biological P and chemical treatmentwith a tertiary stage, as well as an enhanced tertiary treatment on consent levels as lowas<0.1mg/L.AtVWT
