Disc Filters
high capacity on a small footprint
revolutionize your Filtration performance
From raw water screening to waste-water polishing, each DynaDisc filter delivers superior filtration performance for water, waste-water, and water re-use applications.
Raw water treatment
The raw water is pre-filtered in the DynaDisc filter before being treated in the Nordic Water DynaSand filter. The sludge is separated and concentrated in a Nordic Water Lamella separator. This system delivers high-grade processed water, with the least possible amount of reject.
Process water treatment
A DynaDisc filter combined with a DynaSand filter delivers high-efficiency filtration for a wide variety of applications.
superior Design
superior performance
combining intelligent engineering with sophisticated technology, the DynaDisc filter offers a distinct advantage when it comes to filtration applications. our unique design enables professionals in the water treatment industry to get maximum reliability day in and day out, year in and year out.
The filter cassettes are easily replaced in a minimum of down-time. Each disc consists of 8 or 10 filter cassettes. The cassettes are easily removed by loosening a nut. The new cassette is then installed by sliding the cassette over the rod and tightening the nut again.The filter is equipped with an inlet channel
connected to the raw water inlet when installed in a concrete tank. The water flows by gravity into the center drum, into the disc cassettes and through the filter cloth.The rotation of the disc filter is
driven by a helical-bevel gear drive via a non corrosive synchronous carbon fiber reinforced cog belt.The moving spray bar backwash system and the integrated level tank are some of the specific design details that make the Nordic Water DynaDisc a reliable filtration unit which requires a minimum of maintenance.
complete systems stream line D-operations
in order to meet the demands from municipalities and industrial facilities requiring complete water and waste-water package solutions, we have developed complete system configurations based on our competence and proprietary product line. these proven configurations meet stringent requirements while increasing water recovery and eliminate the need for you to allocate resources for detailed planning and implementation costs.
Benefits
The patented filter cassette:
• Fewer parts – the DynaDisc by Nordic Water has 8
or 10 cassettes per disc, which is several times
fewer than in disc filters from other manufacturers.
This means faster replacement and less weight.
• Filter cloth fastened directly to the cassette body –
reduces the seal length to a minimum.
• Low weight – allows for up to 35 pcs 2.4 m diameter discs to be installed in one unit, providing up to 197 m2 effective filter area.
• Strong cassette body – allows high tension on the filter cloth, prolonging its service life.
The level tank:
• Integrated level tank – provides a long level weir for the filtrate which reduces fluctuations at different
water flows.
• The filtrate in the level tank is used for backwash – less risk for biological flocks compared to when the
backwash water is taken from a much larger concrete tank.
• The chemical solution for cleaning the filter cloth is collected in the level tank, thus reducing acid
corrosion of the concrete.
