Mobile RO station for field and municipal tasks

WODARO PRO-M-500-PLUS is a complete water treatment station designed as an all-in-one solution. The design has been developed for service companies, municipal utilities, municipalities, and users who need efficient and repeatable water treatment without building an extensive fixed installation.

The unit performs well wherever high-quality treated water is needed during operational work, periodic tasks, service interventions, and crisis situations. The mobile frame with transport wheels makes it easy to move the station between facilities, intake points, and work areas.

Main advantages

• Mobile, self-contained solution – the entire station mounted on a durable frame with transport wheels.
• Plug & Play – quick installation and start-up, without extensive fixed piping.
• High-capacity filter cartridge with anti-scale effect – effective protection of membranes and pumps.
• Mixed post-filtration that ensures exceptionally low electrical conductivity of the permeate – ideal for PV washing and filling central heating systems.
• Intelligent controller that simplifies operation even in demanding field conditions.
• Output of up to 500 l/h with low energy consumption – approx. 0.65 kWh.
• Designed for applications that do not require a constant water supply, e.g. periodic work, emergency points, service interventions.

Applications

For municipalities, utility companies, service firms and emergency services

• Creating mobile water treatment points during supply interruptions or contamination of the water network.
• Support for operations in crisis situations such as floods, intake failures, and local contamination – after appropriate pre-treatment of raw water.
• Filling central heating and cooling systems in municipal buildings with water of very low conductivity.
• Washing photovoltaic panels, glazing, façades, and municipal vehicles with water free of streaks and deposits.
• Supporting operational work in industrial plants, wastewater treatment facilities, water utilities, and cleaning companies.

How the WODARO PRO-M-500-PLUS station works

The unit operates as a mobile water treatment station based on reverse osmosis technology. The applied water filtration system has been built to combine effective raw water preparation, protection of components, and the production of very good permeate quality.

Full filtration process

In the first stage, raw water enters the VIKING pre-filter housing with a B520-PRO-AS cartridge. This element is responsible for retaining mechanical impurities and limiting scale precipitation, thereby effectively protecting downstream components, including the pump and membranes.

The water is then directed to two XLP11-4040 RO membranes. This is the key stage of the reverse osmosis system, where the vast majority of dissolved salts and other contaminants are removed. The reduction of dissolved salts reaches approximately 90–95%.

After passing through the osmotic membrane, the purified permeate goes to a 14-liter buffer tank. An additional mixed-bed ion-exchange cartridge is installed at the outlet. This post-filtration stage further lowers the electrical conductivity of the water, which is particularly important wherever water with very low mineral content is needed, for example for washing PV panels or filling central heating systems.

Stable operation is provided by an efficient GRUNDFOS pump, and the entire system is supervised by an intelligent controller. Configured this way, the reverse osmosis filter allows convenient field operation, reduces deployment time, and supports safe use in municipal and technical conditions.

Optional upgrades

Suction-pressure pump with sand filter

For an additional fee, the WODARO PRO-M-500-PLUS can be equipped with an external suction-pressure pump set together with a sand filter. This is a practical solution especially for municipalities and emergency services when drawing water from rivers, open reservoirs, or wells.

Such a set helps with the initial removal of sand and suspended solids, as well as ensuring stable feed pressure for the station. As a result, the mobile water treatment station operates more safely, and the RO membranes are better protected against silting and damage.

Safety and operation

The station has been designed as an industrial-grade device using materials approved for contact with water. This makes it suitable for more intensive use in technical, municipal, and emergency applications.
