Water & Wastewater Treatment

PUMP CENTRE CONFERENCE & EXHIBITION 2014 PREVIEW 11 G How advanced rotatinG equipment sealinG tecHnoloGies Help improve operational efficiency Steve Saunders, AW Chesterton As many waterworks and sewage treatment works struggle to maintain profitability, plant management is continuously looking for ways to increase their internal efficiencies. The biggest impact in overall cost reduction is to focus on the operating costs of production equipment. For rotating equipment, the primary variables are equipment component reliability. Increasing equipment reliability lowers component usage which directly leads to reduced acquisition costs. Advanced sealing technologies exist today that can improve sealing reliability at plants tremendously. Maintainability is greatly improved with today's split-sealing technology, leading to further reductions in maintenance costs. H nine ways to fail a seal Steve Moore, Pump Centre This presentation quickly outlines the key parameters that determine the things that can significantly shorten the life of pump seals. i cHoosinG tHe riGHt motor for tHe application – How to naviGate tHrouGH tHe modern cHoices available Dan Banks, ABB With the release of commercially competitive IE4 synchronous reluctance (SR) motors, permanent magnet options, induction motors IE2/IE3/IE4, this presentation guides the purchaser through the key points to consider both for operational and optimisation of the overall 'wire to water' efficiency. J intelliGent drive train selection Daniel Crosthwaite, Siemens IA & DT Intelligently matching the mechanical and electrical elements of a drive train solution to the application to reduce whole life costs. K benefits of usinG vsd for pump control Stephen Takhar, Vacon Drives AC drives dedicated to improving flow control in water and wastewater applications. Combining core functionality with features that are specifically designed for flow control applications, such as single and multi-pump solutions. l vsd tecHnoloGy to boost system efficiency and performance Ian Anderson, Danfoss This technical presentation will explain how pumping system performance and efficiency can be maximised with the implementation of the latest VSD technology when applied correctly. m pump cHaracteristics: an introduction to pressure-surGe analysis Joana Amorim, BHR Group Potentially dangerous scenarios may arise when pumps trip or valves suddenly slam shut. Pipeline integrity may be at risk. This breakout looks at some of the causes, consequences and amelioration of pressure-surge events in pumped systems. n use of damped non-return valves for surGe mitiGation John Sheppard and David Mitchell, Atkins Global Example pumping station design, with significant static head, where good modelling and fine tuning of a damped non-return valve reduced the effects of surge to acceptable levels, removing the need for surge vessels. o an introduction to resilient HinGe-cHecK valves Jason Dean, MGA Controls This session gives an introduction to resilient and recoil resilient hinge-check valves, designed for clog-free vertical or horizontal flow of raw sewage and sludge. Non-return valves (NRV) now incorporate many innovative features, which minimise persistent health & safety and maintenance issues, while maximising operational performance, with a significant reduction in valve energy consumption. The release of WIMES 8.09 valve specification heralds a new development for NRVs in the UK, providing a product being viewed as offering 'significant whole life cost benefits' to UK water companies.
