Nitrate removal filter OPD 15-125

Product detailed description

These devices for the removal of nitrates from water are designed for connection to the main water supply of the building and for central filtration.  

The OPD series filters are intended for the removal of nitrates for the entire building, specifically for medium and larger properties. They are an excellent choice in terms of price/effectiveness ratio.   

They are fully automated modern devices that efficiently remove nitrates from the water. The OPD series filters are usually installed in the technical room on the main water supply into the building. The product is certified and designed for contact with drinking water.

The OPD series filters have a high-quality control unit PENTAIR Autotrol 255/760 with proven diaphragm technology. These sturdy control units are an affordable solution from a leading manufacturer of water treatment components - PENTAIR - while maintaining proven quality. 

Installation is very simple. All models have a 1” connection to the pipe with external thread. Just connect it using a braided hose or other connecting material to the water supply. 

During operation, nitrates are removed using a special filtering medium. The filter contains ion-exchange resin (ionex, anex type), which exchanges nitrates (NO3-) for chloride ions Cl-. During the regeneration of the device, nitrates are removed from the filtering medium and flushed into the drain. At the same time, the filtering capabilities of the medium are regenerated using a salt solution. 

During operation, the OPD series filters utilize 7 regeneration cycles. The control unit is responsible for directing the water flows in the filtering system during operation and regeneration. Through the regeneration of the filtering medium, the filter is ready for operation again. Regeneration is performed in automatic mode, consuming only about 6 kg of salt. The salt container is connected to the control unit using a PE hose of max. 2m long. 

Extended warranty 3 years.

Transportation of the filtration device

We recommend sending the device on a pallet to avoid damage during transport. If you are purchasing regeneration salt together with the filtration device, you can add the pallet to your cart along with the salt.

Installation and service of the device

Installation and delivery will be handled by our own service technicians (we have 14 authorized service technicians throughout the Czech Republic and Slovakia). If you are interested, we are happy to create a price quotation for you. The installation price depends on the complexity and the materials used (connecting hoses, valves, etc.).

We recommend performing regular
service exchanges once a year. The price of a service exchange is 1,990 CZK + travel expenses, which is charged a flat rate of 590 CZK (for Prague and Brno 990 CZK) if the technician's trip is associated with other installations or services along the way.
