How we used Belt screens to ensure trout a continuous supply of clean water

The trout farm uses surface water from a river for its flow-through system. In autumn and during storms, the water intake was heavily clogged with leaves, twigs, and other coarse debris. This required frequent manual cleaning, caused unplanned outages, and burdened downstream pumping and oxygenation equipment. The solution was to install fully automatic self-cleaning Belt screens at the water intake point. The goal was to ensure a continuous supply of clean water to the trout tanks.

Return on initial investment in the equipment
The initial investment in automatic Belt screens pays back within 3 to 5 years purely on the basis of tangible savings resulting from reduced labor and avoided repair costs. If the invaluable benefit of reducing the risk of potential mass fish mortality is also taken into account, the system proved to be a crucial and highly effective solution for ensuring the long-term sustainability and profitability of the trout farm operation.

Benefits
Installation of the Belt screens brought the trout farm significant operational and financial benefits, primarily by protecting sensitive and critical downstream components. Consistency of treated water supply is essential for process stability. Clean and consistent flow ensures that critical downstream equipment, especially aeration and oxygenation units, receives the required flow. This guarantees optimized oxygenation and maintains high dissolved oxygen levels that are absolutely crucial for the optimal health and growth of trout. The system is designed for seasonal resilience in colder climates. An integrated tilting mechanism for winter operation ensures zero risk of frost damage. By allowing the entire belt to be fully removed from the water during sub-zero days, it prevents ice formation that could cause structural damage.
