Technical overview

PVC-Alloy Hollow-Fibre UF — Module Variants

Litree describes its LH-series modules as inside-out ultrafiltration modules built on a self-developed PVC-alloy hollow-fibre filament, with a pore size of 0.01 µm. Three module sizes — LH3-0650-V, LH3-1060-V, and LH4-1080-V — cover 10 to 74 m² of membrane area per module. Litree prints "Volume" as a range in m³/h for each model without stating its basis (flux, temperature, feed quality or filtration mode), and lists dead-end or cross-flow filtration. It names three process steps — filtration and production, backwashing, and maintenance cleaning — and publishes no figures or cleaning chemistry for them.

Generated illustration of a rack of eight tall slender white PVC ultrafiltration membrane modules standing vertically in a parallel array on a steel frame, with upper and lower horizontal manifold headers connecting the module ports, in an industrial plant room. A compact text block at the top-left carries the headline "Module rack", with "Module" picked out in cyan, and the subtitle "Illustration · not a Litree-published rack design".
Close-up product photograph of the top end of a hollow-fibre UF membrane module — black threaded top end cap with a small round pipe port fitting at the top face, stainless-steel circumferential band clamp at the cap-to-body junction, upper portion of the white PVC cylindrical body visible below the clamp.

Cyan arrows: feed enters the fibre bore (arrow up the fibres), permeate crosses the fibre wall (arrows pointing outward), filtrate collects on the shell side. Callouts: 1 Feed enters the fibre bore; 2 Permeate crosses the fibre wall, 0.01 µm-pore PVC-alloy wall; 3 Filtrate collects on the shell side, outside the fibres, inside the PVC shell. Footer: Schematic · fibre count and ports not to scale.
