W.T.O.S. delivers savingsfrom day oneWastewater treatment plants must not only treat wastewater but also workcost-eff ectively. With the soaring cost of energy and chemicals, coupled withever increasing pressure to fi nd sustainable solutions, saving money whilstmaintaining compliance is becoming more and more diffi cult. W.T.O.S. meetsthese needs with low cost solutions and provides simple integration, deliveringcost reductions from the start. Comprehensive control strategies ensure longtermsavings, whilst ensuring plant compliance and stability.Optimisation without added building work and constructionW.T.O.S. enables process optimisation and robust effl uent compliance without costlynew building work or construction of e. g. tanks or aerators.Quality solutions come as standardOptimise without the cost of trial and error. There are many W.T.O.S. reference installationswith both major water companies and industry leaders.The complete HACH LANGE serviceHACH LANGE guarantees consulting, service and availability from the startwith short lead times for effi cient operation without signifi cant expenditure.

Reduced energy consumptionW.T.O.S. controls aeration for nitrifi cation and denitrifi cation, dependingon the situation, resulting in signifi cant reductions in energy consumption.Reduced chemical consumptionW.T.O.S. accurately controls and doses depending on the load to be treated,which considerably reduces precipitant and polymer use.Peace of mindQuick implementationW.T.O.S. can be implemented within the existing infrastructure and as a result no timeconsuming planning or approval is required. The standard modules can be installed easilyand without programming.W.T.O.S. responds automatically with no manual intervention. HACH LANGE can signifi cantlyreduce the requirement for monitoring and process trouble shooting.

“ W.T.O.S. has reduced power demand by 25%. This representsa substantial reduction in our carbon footprint and saves aroundone sixth of the plant’s operational costs.”Matthew Crowhurst, Senior Wastewater Scientist, Wessex WaterLeigh, Greater ManchesterStockport, Greater ManchesterColne, LancashireChicester, SussexHoldenhurst, DorsetEvery wastewater treatment plantcan make savingsThe standardised W.T.O.S. modules optimise wastewater treatment plants of any size as theycan be arranged in a customised manner for all requirements. Standard interfaces allow forsmooth integration into existing systems. Commissioning is simple and fast, ensuring reliableproject implementation.
