Process requirements

What the filtration duty must achieve

Chemical filtration duties vary from removal of reactor solids and catalysts to polishing before packaging or protection of downstream equipment. A media recommendation begins with complete fluid composition—including minor solvents, oxidisers and cleaning chemicals—because compatibility can change sharply with concentration and temperature.

Viscosity, solids abrasiveness, particle shape and valuable-product recovery affect whether a pad, wound depth cartridge, spun cartridge, pleated element or reusable stainless-steel filter is most appropriate.

Process design

A staged filtration approach

Start with bulk solids removal where needed, then use a depth stage for variable fine-particle loading. Activated carbon pads can be trialled where a confirmed adsorbable colour or odour compound is present. Pleated cartridges provide polishing, while stainless-steel elements suit selected high-temperature, high-pressure or reusable duties.

For batch processes, define endpoint by filtrate quality and pressure/flow. For continuous service, include duty/standby capacity and a safe change-out or backwash strategy.

Selection variables

Data that changes media performance

04

Pressure profile

Record clean and terminal differential pressure.

05

Product recovery

Assess hold-up, flushing and valuable solids or filtrate recovery.

06

Disposal or cleaning

Select single-use depth media or validated reusable metal elements.

Technical questions

Application FAQs

How is chemical compatibility confirmed?

Review every wetted material against the full formulation at actual temperature and concentration, then trial where interaction data is uncertain.

When is activated carbon useful?

When the target dissolved compound is demonstrably adsorbed under the process pH, temperature, concentration and contact time.

Why select stainless steel?

It may suit temperatures, pressures, solvents or cleaning cycles that challenge polymer media, provided the selected alloy resists corrosion.

What causes short cartridge life?

High solids, gels, precipitation after cooling, too-fine prefiltration, excessive flux or chemical swelling can all contribute.
