Lamella Replacement
Lamella pack renewal
Replacing worn or damaged lamella plates restores the effective settling area of a clarifier and returns effluent quality to design performance.
Lamella Replacement
Lamella plates provide the inclined settling surfaces that give a lamella clarifier its compact footprint. Over a long service life they may suffer mechanical damage, deformation or irreversible fouling that cleaning cannot correct.
When effective settling area is reduced — by displaced, bent or missing plates — the clarifier can no longer handle its design flow at the target surface loading rate, and effluent quality falls. Replacing the affected lamella plates is the direct fix.
R+F supplies stainless steel lamella packs matched to the original geometry so the clarifier returns to its rated capacity. For older or third-party units, R+F can assess the existing geometry and supply a compatible replacement pack as part of a retrofit.
The procedure mirrors plate pack replacement: isolate and drain the unit, remove the affected lamella section, install the matched replacement, and verify flow distribution and effluent quality on return to service.
Replacement Procedure
Assess the pack
Identify damaged, deformed or fouled lamella plates and confirm replacement over cleaning.
Isolate and drain
Take the clarifier offline, isolate flows and drain for safe access.
Remove and inspect
Extract the affected lamella section and inspect the frame, feed and hopper.
Install matched pack
Fit the replacement lamella pack with correct angle and spacing.
Commission
Refill, restore flow, and confirm even distribution and target effluent quality.
