Technical FAQ
Questions before selection
How do I select the correct filter size?
Selection requires source water, peak flow, target filtration, working pressure and irrigation application.
Which filtration degrees are listed?
The catalogue lists 20, 50, 100, 130 and 200 micron disc options.
How does automatic backwash work?
The filter bank reverses flow through the disc elements to release retained particles. Detailed control and pressure requirements are confirmed in the proposal.
Can disc filtration follow another technology?
Yes. It can be used after media or centrifugal/screen pretreatment when water quality requires multiple stages.
