Water Treatment

Sintered metal filters for municipal water systems, RO pre-filtration, membrane protection, and ultrapure water production — where long service life and reliable pore retention matter more than cost-per-cartridge.

Industry Overview

Why Metal Filters Outperform Polymer in Water Treatment

Water treatment processes — from municipal intake to final RO membrane protection — place heavy demands on filter media. High suspended solids loads cause rapid polymer cartridge fouling. Temperature swings during CIP cycles destroy pleated polyester elements. Chlorine and oxidising agents attack polypropylene housings.

Sintered stainless steel and titanium filters address all three failure modes. In RO pre-filtration and similar duties, backwashable metal elements are often selected where longer service intervals and reusable media can offset the higher initial cost of polymer replacements.

FILTURE supplies SS 316L and titanium sintered filter elements in pore sizes from 0.22 µm to 100 µm — sized for the specific suspended solids load and membrane sensitivity of your process. For aeration and sparging duties, our sintered porous tubes and diffuser discs provide uniform bubble distribution with minimal energy input.

Custom end caps, housing dimensions, and connection types are produced through our OEM/ODM manufacturing process, with documented pore-size and pressure test reports shipped with every order.

Applications

Where Our Filters Are Used in Water Treatment

RO Membrane Pre-filtration

Protect reverse osmosis membranes from particulate fouling. Sintered SS filters at 1–5 µm upstream of RO arrays dramatically extend membrane replacement cycles.

1–5 µm · Backwashable

Desalination Pre-treatment

Titanium sintered filters are often specified for corrosive seawater environments at SWRO desalination plants, especially where chloride exposure makes long-term SS selection less favourable.

Ti Grade 2 · Seawater service

Ultrapure Water (UPW) Systems

Sub-micron pore sintered elements for semiconductor-grade and pharmaceutical-grade ultrapure water production, with an all-metal filtration structure and low media migration risk.

0.5–2 µm · Low media migration

Municipal Water Intake

Large-format sintered filter housings for raw water intake straining — removing silt, algae, and suspended solids before primary treatment stages.

10–200 µm · High flow

Wastewater Polishing

Final-stage metal filter elements for treated wastewater polishing before discharge or reuse — fine filtration with regulatory compliance documentation.

0.5–10 µm · Certified

Cooling Tower Filtration

Side-stream sintered filter units controlling particulate and biological fouling in cooling tower circuits — backwashable for minimal downtime.

5–50 µm · Chemical-resistant

Ti Sintered Powder Filter Element

Often specified for desalination and seawater handling where chloride exposure makes titanium a more conservative choice than standard SS grades. Material selection should still be confirmed against actual chemistry and cleaning conditions.

Why FILTURE

What Water Treatment Engineers Value Most

Consistent Pore Performance

Unlike polymer media that degrades under backwash pressure, sintered SS retains its rated pore size throughout its service life — providing predictable downstream water quality without manual monitoring of differential pressure trends.

Full Test Documentation

Bubble point test data for filter elements, dimensional records, and material certifications are available on request — meeting the documentation requirements of both municipal utilities and regulated industrial water users.

Custom Fit for Existing Housings

We machine elements to match the exact OD, length, and end-cap specification of your existing filter housings — enabling drop-in replacement without housing modification. Standard dimensions for most major housing brands are on file.

What Water Treatment Customers Say

"

We replaced polymer cartridges with FILTURE sintered SS elements on two sedimentation pre-filter trains. Backwash cycles dropped from every 8 hours to twice a week — a meaningful maintenance saving for our operators.
