Reverse osmosis units are used for production of demineralized water without use of hydrochloric acid and sodium hydroxide. Among other things, the units are used in boiler houses, district heating plants, hospitals, dialysis centres, and laboratories, for process water in the pharmaceutical industry and the chemical industry, as well as in connection with humidification plants. RO units remove pyrogenics as well as bacteria and cause no wastewater problems. The units remove up to 90% of the organic substances and retain 98-99% of the salt in the water.

Advantages

Storage and handling of acid and lye are avoided. The units are extremely space-saving thanks to the compact design. The plants are of high quality, need minimum maintenance, and the reliability of operation is very high.

Unit description

Flow rates for standard modules: 50 l/h - 60 m³/h. RO plants are either produced as standard modules or custom-made according to requirements. The units comprise selected components of high quality. They are automatic with electronic quality monitoring.

Custom-made plants

There are many possibilities of custom-made solutions. Nearly all parametres and components can be varied and combined. EUROWATER has great experience in producing RO pipe systems in many types of materials such as PP, PE, PVDF, and stainless steel. The foundation and frame, too, can be delivered in stainless steel.

3D drawing of container


Above, you see an example of a fully equipped container. The container has been designed for a power plant and the water will be used for cooling water (8 m³/h), boiler water for high pressure steam turbine (6 m³/h), and drinking water. The container includes the following plants: Active carbon filter, pressure filter plant, softening plant with brine tanks, dosing stations, bag filters, doubble-pass reverse osmosis plant, dealkalization plant, booster pumps, and control cabinet. The shown container is insulated and equipped with door-in-door, light, and air-conditioning.

 

The concept


A water treatment solution consists of several treatment steps, e.g. filtration, softening, and demineralization - all controlled from a central control cabinet. These units must be put together on site. If the end-user or the contractor is uncertain if the installation can be carried out locally within the determined economic and temporal scopes, it can be an advantage to order a water treatment plant (container or frame-mounted) which is ready for use when supplied.

The solution is complete with all internal piping and wiring factory-built. The whole plant has been performance and pressure tested in our factory. This safety can be achieved with a EUROWATER frame-mounted plant or a container-installed plant.

With a container, you also have the advantage that the container itseslf is an actual building which in this way can be left out in the project. The containers can be delivered with and without insulation and can be equipped with lighting, air-conditioning, door-in-door, emergency shower, etc. We have constructed many different custom-made plants adapted to specific demands and wishes. Below, you can see different examples of this. We are happy to make quotations for start-up of plants and training of the operating crew.

  • Complete water treatment plant in a 20 feet container. The solution consists of dosing, carbon filtration, softening, and demineralization through a reverse osmosis plant.

Nanofiltration is often used for treatment of drinking water and industrial process water.

Drinking water

  • Reduction of sulphate, chloride, and fluoride
  • Partial softening without use of regeneration chemicals

Industrial process water

Partial softening and reduction of colour and humus from surface water in e.g. the iron and metal industry and paper mills.

Nanofiltration or reverse osmosis?

Reverse osmosis is typically used for demineralization of water, since this filtration method covers the widest field of application (see the diagram). Nanofiltration, on the other hand, is applied in order to reduce unwanted components in full or in part. Unlike reverse osmosis, nanofiltration applies a lower pressure, typically under seven bar, resulting in lower energy consumption compared with a reverse osmosis plant with the same productivity.

You must also choose a nanofiltration plant over a reverse osmosis plant if you want a certain hardness, because a potential demineralization will make the water aggressive and lead to problems with corrosion in the supply network. 

Designed for your needs

EUROWATER offers a broad product range of fully automatic nanofiltration units – based on our well-known modular standard system, which makes it possible for us to combine an optimal plant for your needs.  

The technique behind

Nanofiltration is a membrane technology, which in its mode of operation and construction is very similar to reverse osmosis. A nanofiltration membrane primarily restrains divalent ions and larger molecules. When it comes to the filtration process, a nanofiltration unit is placed between reverse osmosis and ultrafiltration – see the diagram.
