DynaDisc

With a DynaDisc filter, you get superior filtration performance for water, wastewater, and water re-use applications. The DynaDisc filter combines intelligent design and modern technology to give you clear advantages in filtration applications. The unique design features ensure efficient and reliable filtration day after day, year after year.

Intelligent design – efficient filtration
The DynaDisc filter, consisting of multiple filter discs constructed from modular demountable cassettes attached to a revolving inlet drum, maximises the filtration area in an industry leading compact footprint.

Available in two disc sizes, 1.9m or 2.4m diameter, providing up 197m2 net filter area per DynaDisc with up to 35 discs.

Woven filter media, with filter openings down to 10 microns, is bonded to the one-piece modular cassette ensuring optimum uniform media tension maximising filter media life and minimising the number of sealing joint interfaces.

A proven design providing you with high efficiency filtration and high flow rates within the minimum of space.

Filtration Applications

The versatile DynaDisc design is suitable for a variety of filtration applications such as:

• waste water final effluent polishing (tertiary filtration)
• waste water primary filtration
• pre-treatment for MBR processes
• intake and raw water filtration
• algae removal
• recycle and reuse water filtration
• filtration of water for industrial process plants
• pre-filtration before the sand filters
• pre-treatment & protection filtration for membrane plants
• water treatment in the paper and pulp
• water treatment in fish farming (aquaculture)

How the DynaDisc works
The water to be filtered flows via the inlet channel into the rotor drum and then flows by gravity into the filter disc segments through openings in the drum, and passes through the filter media. Suspended solids are separated and accumulated on the inside of the filter cloth.

When the water level inside the filter rotor increases to a pre-set point, the filter rotor starts rotating and the backwash of the filter media starts. The high pressure backwash spray removes the accumulated suspended solids into the reject backwash trough inside the filter. The suspended solids are then discharged via the reject pipe. The discs are submerged to approximately 65 % and the water level of the filtrate is maintained by a level tank.
