- After-sales service and spare parts
A multimedia sand filter is the most fundamental treatment stage. Raw water enters at the top and flows down through anthracite, graded quartz sand and support gravel, where suspended solids, turbidity, sand and rust are trapped. As the bed loads up and pressure drop increases, an automatic backwash reverses the flow, lifts the bed and flushes captured dirt to drain — so the media keeps working for years without replacement.
We size every filter from your flow rate and water analysis, selecting vessel diameter and filtration rate to balance outlet quality against backwash water use.

04Frequently asked questions
01How often does a sand filter backwash?
Typically every 1–3 days depending on raw water quality; ΔP-controlled systems start automatically as the filter loads.
