JET FILTER (JET)
Filtration in any position
The JET filter is an inline filter without any moving internal parts. Its patented design enables very high flow rates, a high diversity of materials and flexible installation in pipelines.
The JET filter is ideally suited for all installation situations, and with minimal wear.
- High cleaning speed (up to 10 m/s)
- Any installation position (horizontal/vertical)
- Easy installation (inline design)
- Low wear (no moving parts in the filter)
- Low flushing water losses
- No increase in differential pressure during filter operation
- Diversity of materials
- Completely wired and tested unit
- Special design solutions for special customer requirements
The raw water flows through the openings in the clamping plate, entering the filter elements located behind them. The reductions in cross-section bring about a proportional increase in the axial flow velocity in the filter elements of 5-7 m/s. There is a conical dirt collection container located at the end of the filter elements, into which all the filter elements are brought together.
The raw water is filtered according to Bernoulli's law in the last third section of the filter elements. The raw water flows through the filter elements from the inside to the outside. The clean water then flows around the dirt collection container and exits the JET Filter on the clean water side.
The axial flow velocity in the filter elements of 5-7 m/s guides the dirt particles into the conical 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 time relay 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 elements. Furthermore, a vacuum is generated in the filter elements, 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.

HOW TO GET RID OF MUSSELS
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.
