The Kaldnes® RAS solution
The concept of RAS (Recirculating Aquaculture System) is to reuse a volume of water through continual treatment and delivery to organisms being cultured.
The RAS design and water treatment components used need to accommodate the input of the high amounts of feed required to sustain high rates of growth and high stocking densities, typically required to meet financial outcomes.
Our Kaldnes® RAS semi-closed loop system, with aeration and particle removal, is designed to maximize production while reducing pollution and water consumption.
Solids removal: Particle separation is achieved through our globally recognized Hydrotech Drumfilters™, specifically designed for Aquaculture applications and initially introduced to the market more than 25 years ago.
Biological treatment: Our AnoxKaldnes™ MBBR (Moving Bed Biofilm Reactor) is a continuous process biological treatment of carbon and/or nitrate using biomass attached to a moving carrier. The compactness and lack of backwash are ideally suited for Aquaculture requirements.
All operations and water quality are continuously monitored online via our industrial SCADA System for surveillance, operation and alarm management.
