High productivity

The raw water flows through the inlet opening, entering the filter element located behind it. The reductions in cross-section bring about a proportional increase in the axial flow velocity in the filter element of 5-7 m/s. The raw water is filtered according to Bernoulli's law in the last third section of the filter element. The raw water flows through the filter element from the inside to the outside. The clean water exits the JET Filter S through the clean water nozzle on the side of the filter.

The axial flow velocity in the filter element of 5-7 m/s guides the dirt particles into the dirt collection container. The filter backwash process is initiated by the differential pressure (the pressure difference between the raw and clean water side). An adjustable timer in the electrical control system additionally enables the filter backwash process.



At the start of filter cleaning, the motor-driven backwash valve opens. A small amount of the raw water then flows through the backwash opening. This flushes the dirt particles in the dirt collection container out of the filter. During backwashing, the axial flow velocity in the filter elements increases to up to 10 m/s. This high axial velocity additionally cleans the filter element.

Furthermore, a vacuum is generated in the filter element, which guarantees that backwashing proceeds from the outside to the inside with clean water. The backwash process is complete after 10-20 seconds and the backwash valve is closed automatically. Filtration is not interrupted during backwashing.

Mussels and mussel larvae are fast becoming a major threat to industry. Once mussels or their larvae are in your system, they can multiply unhindered and incapacitate entire pipeline networks. The unique MUSSEL STOP system from DANGO & DIENENTHAL offers reliable protection for your plant components against unwanted mussel infestation, thereby minimizing breakdowns and maintenance costs.
