BACKWASH DRUM FILTER S (RTF-S)
Tried-and-tested technology in a new design
This filter impresses with excellent backwash performance and a compact design. A customized selection of materials is possible for the most difficult media.
An automatic filter specially devised for low flow rates.
- High cleaning speed (4-10 m/s)
- 100% cleaning of the entire filter area
- Low flushing water losses
- Robust design
- Fine filtration ≥ 5 μm possible
- Uniform feeding of the entire filter area
- Completely wired and tested unit
The raw water enters the filter via the inlet flange and flows through the filter element from the inside to the outside. The solids in the raw water are retained on the outside of the filter element. The purified water leaves the filter through the clean water outlet.
A differential pressure measurement in the raw water inlet and the clean water outlet determines the degree of contamination of the filter element. At a defined differential pressure, the backwash process is activated. An adjustable time relay in the electrical control system additionally enables the backwash process. At the start of filter cleaning, the motor-driven backwash valve opens, generating atmospheric pressure in the backwash line and the flushing window in the filter housing. Due to the excess pressure inside of the filter element on the clean water side, the solids retained on the outside of the filter element are now forcibly backwashed into the atmosphere against the direction of filtration.
The rotation of the filter element guarantees the 100% cleaning of the filter surface. The flushing process is complete after 15-20 seconds and the backwash valve is closed automatically. Filtration is not interrupted during backwashing.
- Wound wedge-wire screen cylinder with shaft support
- Wedge-wire screen based on welded triangular rods
- Highly robust design
- Can be manufactured in various stainless-steel grades
- Filter fineness ≥ 5μm
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.
