The Vantage M83 RO system from Siemens uses energy-efficient components, such as a variable frequency drive (VFD) and controlled feed pumps, resulting in potential energy savings ranging from 15%, up to 60%, compared to conventional in-line starter controlled pumps. It also has enhanced water recovery and a streamlined chemical cleaning process. Unnecessary water consumption can be avoided by modifying system settings during startup, standby, and shutdown conditions that reduce waste without jeopardising product water quality. Other features include system commissioning and touch screen controls with operational trending displays for monitoring system performance.
The system requires a footprint of just 82.5×429.5 cm and has a height of 237.8 cm, which allows it to fit through standard doorways of industrial buildings.
In Europe, the Vantage M83 RO units are available in three equipment models: Economy, Deluxe and Select. Each unit is a single-pass RO system mounted on an industrial coated structural steel frame or a stainless steel frame for the Select package. The RO unit includes a cartridge filter, high pressure feed pump, glass fibre reinforced plastic (FRP) side-entry pressure vessels and spiral-wound thin film composite RO membranes.
All system models are controlled by a programmable logic controller (PLC) with a colour touch screen Human-Machine Interface. The Deluxe and Select models include a VFD-controlled feed pump to save energy with flexible flow demand and an integrated CIP system to facilitate ease of cleaning without additional equipment. 
The system can be used for the production of process and boiler feed water as well as for wastewater and process water recycling. It is suitable for a range of industrial applications such as the food and beverage, power, microelectronics and solar industries.
