Precision filtration for cleaner, compliant wastewater.

Baldwin Industrial Systems designs and manufactures industrial filtration and polishing units that remove sediments, oils and contaminants with proven efficiency.

Engineered in Australia, these systems provide reliable, compliant performance and integrate seamlessly into broader wastewater treatment processes.

What Is Water Filtration?

Cleaner water. Sustainable results.

Water filtration removes solid waste, sediments and pollutants from wastewater before discharge or reuse.

It improves water quality, protects downstream stages and enhances the overall performance of treatment plants.

Baldwin filtration systems may incorporate multiple stages, including coarse filter screens, sieve bend screens, and multimedia filtration, to achieve effective contaminant removal.

How the Filtration & Polishing Process Works

Two stages. One high-performance result.

  1. Filtration: Removes larger solids and suspended matter using coarse or fine media.
  2. Polishing: Targets residual suspended solids and trace chemicals to achieve high-quality effluent suitable for discharge or recycling.

Polishing media may include hydrocarbon-specific filters, activated carbon, or multimedia cartridges, depending on site requirements.

Modules can operate as stand-alone units or be integrated into complete wastewater treatment systems for enhanced performance.

Industries Using Filtration & Polishing Media

Trusted across the Australian industry.

Filtration and polishing units are widely used in:

  • Mining
  • Ponds, lakes and dams
  • Manufacturing
  • Petroleum and petrochemical facilities

Each system handles varying contaminant loads while supporting compliance with environmental regulations.

Frequently Asked Questions

What is filtration in wastewater treatment?

It is the process of removing solid and dissolved contaminants from wastewater before reuse or discharge.

What is the difference between filtration and polishing?

Filtration removes larger solids, while polishing targets finer particles and trace chemicals to achieve cleaner effluent.

Can filtration units be used on their own?

Yes. Baldwin filtration units can operate independently or as part of a complete treatment system.

What filtration media are available?

Options include coarse and fine filter screens, hydrocarbon-specific polishing media, activated carbon and multimedia configurations.

Where are filtration and polishing units used?

They are installed across mining sites, refineries, water plants and manufacturing facilities requiring compliant discharge.
