The Seradisc filter includes 16 discs which screen particulates of approximately 4mm and above. Screening of smaller particulates is achieved by installing additional discs (packs of 16 available separately) onto the assembly. The maximum number of discs that should be installed is 42, providing screening of 0.1mm and above.
To enable the filter to operate in a relatively shallow water depth without the ingress of air, the discs have break-off tabs allowing a portion of the disc to be broken off to facilitate lower immersion. In this case, the minimum depth of water is 130mm.
The Seradisc filter can be cleaned by simply running a finger along the discs. Heavier contamination may be removed by rinsing the Seradisc in a container of water, or by hosing down.
For increased capacity or larger diameter pipes, Seradisc units may be connected in multiple configurations as illustrated in the examples below. Note the flexible coupling shown is included in each Seradisc kit.

filters connected in parallel

filters in parallel configuration
Particulate sizes are calculated. Due to the flexible nature of the discs, Seradisc filters fitted with lower numbers of discs may allow ingress of particulates slightly larger than as indicated
filter with 16 discs
filter with 32 discs
filters in series configuration
By configuring a number of filters in series, the flow rate will remain the same as for one filter. However, the benefit is that the cleaning interval is increased.
