NP Filters Water treatment for aquaculture The success of fish farming is totally dependent on the water quality. Securing good water conditions to allow for good fish health and high production yield, is therefore one of the most vital factors.

State of the art solutions for particle removal With focus on land-based fish farming, NP Innovation have refined the design of aquaculture filters. The products have been developed with a strong focus on functionality, performance, and robustness – but also on minimizing the investment and running costs, to make the products both technically and commercially attractive. NP Innovations mechanical self-cleaning filters for aquaculture applications are designed for high performance in water-treatment systems, where it is essential to minimize particle break-up.

at a very low footprint, ensuring not only favor- able capex but also a very low opex over time. How drum filters and disc filters work As the name indicates, the drum filter is built around a drum-shaped skeleton enclosed with external filter panels. The untreated water flows into the drum, and gravity drives the water through the filter panels and out of the drum (figure 1a). In the disc filter, the influent water also enters a central drum. The drum has a number of openings that distributes the water to the filter discs (figure 1b). The disc segments are made up of several filter...

Model Range 1. Stainless steel tank version 2. Drumfilter with FRP tank (Fiberglass Reinforced Plastic) 3. Freestanding stainless steel tank version 4. Stainless steel frame version

NP Innovation have adapted the disc filter technology for aquaculture criteria and made our Discfilter the most optimized disc filter solution on the aquaculture market. NP Discfilter The filter has several filter media discs attached to a drum. The filter is rotated by a helical worm gear motor via a lubricant-free chain, running on the peripheral of the centre drum, leading to lower power consumption and reduced maintenance costs. The optimized way of filtering water The NP Discfilter is a mechanical self-cleaning filter for removal of suspended solids, specially designed for aquaculture...
