SuperDrum is an automatically self-cleaning micro-screen filter designed for removal of suspended solids. SuperDrum is available in a variety of sizes and designs so you can find one to suit your needs. SuperDrum filters water through the machine by gravity and has a low pressure drop. In addition SuperDrum also has a low energy cost, which together with a proven design provides a low life-cycle cost.
Proven robust construction
The SuperDrum filter comprises several filter panels mounted around a rotating inlet drum and provides a simple yet robust solution for the removal of particles.
SuperDrum is available in five different sizes: 0.6 m, 0.8 m, 1.2 m, 1.6 m and 2.0 m in diameter and provides up to 22.5 m2 net filter surface per machine.
The woven filter fabric, with a density down to 10 microns, sits firmly on the filter panels and is uniformly tensioned to maximise fabric life and minimise the number of attachment points.
A proven and robust design that provides high efficiency filtration with minimum pressure drop.

How SuperDrum works
The water to be filtered enters the drum via the inlet and gravitates out through the filter in the drum outer edges. The particles are separated and stick to the inside of the filter.
When the water level in the drum reaches a preset level, the drum starts to rotate and the filter backflush starts. By means of high-pressure washing SuperDrum uses the filtered water to remove the accumulated particles and deposit them in the pan. SuperDrum operates at a 65% level of immersion and the filtered water is controlled by a dam.
Advantages of SuperDrum
• Fewer parts per drum segment for easy maintenance and reduced weight.
• The fabric is bonded to the filter panels, which maximises densification and allows a high fabric tension, thus extending the operating life cycle.
• Low weight allows the installation of up to 22.5 m2 effective filtration per DynaDrum.
• The amount and load levels are based on the actual rather than theoretical filter surface.
Compact width overflow and bypass:
• Internal and external width opportunities.
• Space saving, expandable width overflow.
• Protection against foreign objects in the backwashing system.
• Backwashing systems that minimise water and energy consumption.
• Light, lubrication-free and corrosion-resistant chain drive.
Two variants – one method
SuperDrum is available as a standalone unit with a chassis in stainless steel or with a framework for installation in a concrete tank. Whichever you choose, you get the same reliable industry-leading rugged design.
