Does sludge collect evenly over the entire radius of the clarifier?
Yes, it does. The sludge is removed evenly through the adjustment diaphragms equipped on each suction unit. Thus, the suction units farthest from the center of the clarifier ensure sludge intake in accordance with the vast serviced bottom area. The suction units closest to the center of the clarifier run under a lower vacuum, since they service a significantly smaller bottom area.
How is it possible to ensure minimal passing out of suspended solids?
The minimum passing out of suspended solids is achieved due to: (1) the sludge is completely removed from the bottom, it does not accumulate and does not decay; (2) the only sludge suction pipe has a sufficiently low surface area compared to other systems, which allows for a laminar flow of liquid in the clarifier during the movement of the suction scraper.
What is the maintenance frequency of the standard Ekoton radial suction scraper?
The standard maintenance frequencies:
- Lubrication of the traction trolley bearings: 1 time in 3 months,
- Oil change for drives: 1 time in 2 years,
- Sludge pipe maintenance: 2 times a year,
- Replacement of the track cleaner brush: 1 time in 2 years,
- Replacement of the weir cleaner brush: 1 time in 3 years,
- Replacement of suction unit rubber apron: 1 time in 4 years,
- Replacement of polyurethane wheels: 1 time in 6-8 years.
- For information only, data may vary depending on specific operating conditions.
