Tube Settler Media — PP & PVC Inclined Lamella for Clarifiers
Inclined tube settler (lamella) media in PP or PVC for clarifier upgrades and new settling tanks. Three tube sizes — 35 / 50 / 80 mm — supplied as welded modules sized to your clarifier, with support frames quoted on request. Send us your clarifier dimensions and flow, and we will calculate the settler area and module count.

Tube settlers multiply the effective settling area inside a clarifier without new civil works: wastewater passes up through inclined tubes at 60°, solids slide down the tube walls, and clarified water leaves at the top. Sheets are heat-welded into rigid modules (no adhesive), sized to the clarifier, and installed on a support frame. Choose PP for chemically aggressive or high-temperature wastewater and outdoor tanks (UV-stabilised); choose PVC for municipal and general industrial clarifiers where budget matters most.

Which tube size?
35 mm gives the largest settling area and suits well-pretreated industrial wastewater; 50 mm is the standard choice for municipal and industrial secondary clarifiers; 80 mm passes solids more freely and suits raw-water pretreatment and high-solids water. If you are not sure, send us your water data and we will recommend the size — a tube that is too small for your solids will clog, and we would rather tell you that before you order.
What to send for a quotation
(1) clarifier length × width × depth (or diameter for circular tanks), (2) design flow (m³/h), (3) wastewater type and suspended solids. We return the required settler area, module layout and a quotation; support frames in stainless steel or FRP can be included.
