Solid-Liquid Separation Equipment, Engineered and Built in One Factory
Every machine below is designed, manufactured and tested by Loway — not rebranded, not assembled from bought-out parts. From coarse headworks screening to the driest filter cake, the equipment range covers the whole separation train: filter presses, belt presses, screw presses, drum screens, drum filters, bar screens and grinders. Proposal sized from your sludge sample, exported to 56+ countries.
- 10equipment lines, all in-house engineered
- 5+plate, cloth and frame materials available
- 56+countries we have shipped complete lines to
- 1factory — one supplier, one warranty, one P&ID
Dewatering — Make Dry Cake From Any Sludge
Three machine classes for three operating realities. Filter presses push solids highest; belt presses run continuously at scale; screw presses handle oily, greasy and hard-to-condition sludge with the least maintenance.
Dewatering — batch
Filter Presses
Recessed chamber, plate & frame, and membrane squeeze presses for the driest cakes a plant can ship.
- Up to 25 m³
- 16 bar
- 1.5–40% feed DS

Dewatering — continuous
Belt Filter Presses
Continuous belt presses for high-throughput municipal and industrial sludge, with low polymer consumption.
- 24/7 operation
- 8–25 m³/h
- 2–5% feed DS

Dewatering — low maintenance
Screw Presses
Multi-disc screw presses, self-cleaning and low-energy, for oily, greasy and hard-to-condition sludge.
- 24/7 operation
- Self-cleaning rings
- 2–6% feed DS

Fine Screening & Filtration — Protect What Follows
Two machines for the fines that survive coarse screening. Rotary drum screens stop hair, fibres and grit upstream of the dewatering stage; rotary drum filters polish process water and recover solids downstream.
Fine screening
Rotary Drum Screens
Internally fed rotary drum screens for fine wastewater screening and MBR protection — screening, washing and dewatering in one unit.
- 0.2–3 mm cut
- MBR-ready
- 3-in-1 design

Filtration
Rotary Drum Filters
Self-cleaning vacuum rotary drum filters for liquid-solid separation and microfiltration of process water.
- 1–50 m² area
- Vacuum
- 50 μm filtration

Headworks Protection — Stop Wipes and Grit Early
Coarse screening and inline size reduction at the front of the plant. Catches what would otherwise shred pumps, blind nozzles and jam dewatering presses.
Coarse screening
Rotary Bar Screens
Heavy-duty chain-driven multi-rake bar screens for WWTP headworks and pump stations, with jam-free design.
- SS304 / SS316L
- 1–6 mm spacing
- Deep-channel rated

Inline grinding
Twin-Shaft Channel Grinders
High-torque inline grinders shred wipes, rags and plastics directly in the wastewater flow, protecting downstream pumps.
