Water is a precious resource and we, at RHI we are fully committed to its protection. This enthusiasm for protecting water coupled with our passion for innovation that drives RHI to find ways of using water better. The HYDRAPRO® GR is the result of this pursuit. Our greywater recycling system turns bathing water into hygienically clean process water. Using a fully automated mechanical process without the need for chemical additives the water is available for re-use. Toilet flushing, cleaning buildings and irrigation constitute the principle uses. Membrane technology is at the centre of the system. This ultra filtration method ensures the removal of suspended solids as well as bacteria and viruses ensuring that the EU guidelines for bathing water quality are adhered to.

The controls for the HYDROPRO® GR can be fully integrated into the central building management system or operate as a standalone unit. At the heart of the controls lies powerful PLC technology which monitors every aspect of the process to ensure optimal performance is maintained. Ease of servicing and maintenance is paramount in the design.Aeration of the filtering plates ensures that these are kept clean and maintenance and  chemical requirements are kept to a minimum.

The HYDRAPRO GR offers not only the benefits of recycling water but, the option to combine an advanced heat recovery system and / or rainwater harvesting system is also available. As a result your business can reap additional energy and water savings.

Due the high volumes of bath and shower water used within hotels, leisure centres, and residential apartment blocks these building types are ideally suited for greywater recycling. The recycled bath and shower water can be re-used to flush toilets and for irrigation.
