STARK Stainless Steel Ultrafiltration System (Whole-House, Dual Canister, Auto Backwash)

Stainless Steel Ultrafiltration System Overview

The STARK Stainless Steel Ultrafiltration System is a compact, whole-house solution for municipal tap water. Two stainless UF housings deliver clear, hygienic water to all household taps while preserving beneficial minerals.

How UF Works

UF is a physical barrier process. 0.01–0.02 μm hollow fibers block suspended solids, bacteria and colloids. Periodic backwash/forward flush automatically removes fouling and restores flux.

Key Features

• All-stainless build: SS304 (SS316L optional) housings and rigid frame.
• Auto backwash valve: programmable cycles; manual option available.
• Stable whole-house flow: consistent pressure for kitchens, showers and appliances.
• Food-grade materials with chlorine-tolerant PVDF/PES membranes.
• Easy service: front access, quick drain, lockable casters.

What It Removes / What It Doesn’t

Removes: turbidity, rust, sand/silt, bacteria, protozoa, microplastics, colloids, some organic macromolecules.
Does not remove: dissolved salts, hardness, nitrate or fluoride. For TDS/fluoride reduction, combine with a STARK RO unit at point of use.

Installation & Maintenance

• Install on a level floor near inlet, drain and power. Add a bypass and pressure gauge.
• First start: forward-flush 5–10 minutes until clear.
• Set automatic backwash every 2–3 days (adjust by water quality/use).
• For high turbidity areas, add a 5 μm prefilter upstream.
• Typical membrane life: 24–36 months depending on feed water and maintenance.
