With global efforts shifting towards achieving a more sustainable future, it has never been more important for companies in the pharmaceutical sector to follow suit and begin incorporating energy efficient measures into every aspect of their operations.
In 2019, the European Commission (EC) outlined its strategic approach to reducing the environmental impact of the pharmaceutical industry, as part of its goal to achieve a sustainable Europe by 2030. Among the key areas listed for action were the promotion of greener manufacturing methods and the encouragement of innovation in water treatment technology for the sector.
In pharmaceutical manufacturing, a reliable and consistent supply of purified, treated water is essential for production. At VWT Ireland, our Orion Series offers the ideal solution to ensure a continuous supply of high-quality process water in the necessary quantities to optimise a company's processes. The system combines softening, reverse osmosis (RO), and continuous electro-deionisation (CEDI) technologies, which can be fully or partially hot water sanitised and is available with a range of flow rates, from 0.5 to 20 m3/hr.
Our premium Orion S Series integrates tried and tested processes with a range of sustainable features, providing an unrivalled water technology package that can help pharmaceutical companies meet their environmental targets. Developed to provide greater long-term operational savings compared to the classic (C series) and mid-range (E Series) Orion models, the Orion S optimises energy and water consumption to deliver our most sustainable water purification solution yet.
By installing or upgrading to the Orion S Series, customers can benefit from several sustainable features and advantages, including:
- Chemical-free sanitisation
- Integral recovery RO and concentrate recycle
- Low energy full fit membranes
- Increased water efficiency process enhancements
- Reduced energy process enhancements
- Reduced water discharge and product flow during recycle
- An energy saving ‘standby mode’
- A sustainability display detailing CO2, water and energy usage
- And full compatibility with VWT’s AQUAVISTA digital monitoring services.
Through the use of the Orion S Series it is therefore possible to achieve a number of savings including up to a 30% reduction in the level of CO2 released during a plant’s operation, up to a 40% water footprint recovery and a minimal chemical footprint. Users can also rest assured that the system is made from 99% recyclable materials and supplied with an end-of-life recycle guide.
Moreover, by integrating our AQUAVISTA digital services, engineers can remotely access and monitor operational data, maintenance schedules, performance, and cost KPIs. This is particularly beneficial for manufacturers in Ireland as it helps reduce downtime, waste from spoiled batches of product, and optimises maintenance costs and operator time. With AQUAVISTA Assist, operators can also have peace of mind with real-time online support from Veolia's team of process experts.
With the introduction of the Orion S Series, we have successfully incorporated technology that would have previously been provided on a case-by-case basis. In the past, VWT Ireland collaborated with large-scale pharmaceutical manufacturers to install more sustainable devices to support second-generation Orion plants. Specifically, this involved the installation of additional recovery RO systems. However, with the launch of the Orion S, which includes recovery RO systems as standard, we have created an ideal system that meets the needs of pharmaceutical manufacturers. As a result, several companies have approached VWT Ireland to upgrade to this latest system.
We are dedicated to providing lifetime service to our customers in Ireland. Our team, spread across the country, offers preventative and corrective after-sales programs to ensure the long-term efficient operation of our installed plants.
