Reverse Osmosis treatment for high quality water without chemicals

From the smallest café to the largest production facility, BWT has a range of Reverse Osmosis units designed and developed to protect a single appliance, process or whole facility.

Installed as a single unit or as part of a modular water treatment solution, BWT Reverse Osmosis is the most effective and reliable form of water treatment available for the removal of undesirable elements from a given water supply. It will remove 90-99 % of all dissolved solids and 98% of all bacteria and fine suspended particles below 1 micron particle size. Reverse Osmosis is a physical process that makes use of a semi-permeable membrane to separate water from substances dissolved in it.

How RO system works

Reliable and maintenance-friendly

Reverse osmosis is a membrane separation process which, by means of a high water pressure, is capable of separating (retaining) the dissolved salts (ions) present in the raw water and letting the pure water molecules pass through the membrane. In reality it is the water molecules which are removed from the dissolved salts and not, as you know from ion exchange, the ions that are removed from the water. The dissolved salts are removed almost 100 % and the membrane pores are so small that even micro organisms such as bacteria and pyrogenes cannot penetreate.

The pure water (permeate) is collected in the reservoir and from here pumped to point of use. The “dirty” water (concentrate) is fed to drain. Programmable logic controllers (PLC) are often used for monitoring conductivity levels and other operating parameter making even larger systems easy to monitor and control.

BWT PERMAQ® Pro 1800

The BWT PERMAQ® Pro 1800 is the perfect solution for large autoclaves, steam generators, dishwashers, laundries and car washes, where a low conductivity (< 20 μS/cm) is required and where space is limited. The design is compact, maintenance-friendly and allows for easy installation in confined spaces. It has been designed to be simple to use and with a suitable water softener as pre-treatment reliable and stable in operation.

BWT bestaqua 14 ROC

The BWT bestaqua 14 ROC was designed for tough applications in the food service sector. It is ideal for producing very pure water, such as that needed to produce steam for combination steamers or steam ovens, or for a steam feed when baking. It also enables all unwanted substances to be removed from the water effortlessly, allowing the water to vaporise entirely without residues. Reverse osmosis developed specifically for the restaurant trade.

BWT PERMAQ® Pro 2500

The BWT PERMAQ® Pro 2500 supplies high quality permeate for boilers, closed/open cold water cycles in climate systems and cooling towers, closed hot water systems and other process water for industrial applications where a low conductivity (< 20 μS/cm) is required. The high quality, reliability and efficiency of the system is ensured by the inclusion of membranes and pumps selected for their technology and durability.

BWT PERMAQ® Pro 2700

The BWT PERMAQ® Pro 2700 covers a permeate flow range between 6 and 20m3/h for industrial applications. High quality permeate suitable for car washes, boiler water, steam production and district heating, autoclave, evaporators and technical water installations where the reduction of the TDS in the water is very important. Its small foot print, smart design and easy access to all of its components makes it ideal for smaller plant rooms.

BWT PERMAQ® Pro 2900

The BWT PERMAQ® Pro 2900 supplies high quality permeate for use with boilers, closed/open cold water cycles in climate systems and cooling towers, closed hot water systems and other process water for industrial applications, where a low conductivity (< 20 μS/cm) is required. Components are selected with a focus on the latest technology, efficiency and quality. This ensures a reliable and efficient system with high capacity.

BWT PERMAQ® Pro 2000

The BWT PERMAQ® Pro 2000 is ideal for heating and technical process water, where a low conductivity (<20μS/cm) is required. The system has been designed to be used with suitable pre-treament like a water softener to provide an emphasis on simple and stable operation. The advanced control system ensures automatic disconnection should the water supply fall below a prescribed level, protecting the unit and any subsequent installations.
