Wednesday, August 20th, 2025

Location: Adelaide, Australia 

Time:  May 2025 – present 

Job#  16199

 

Taurus Engineering was engaged by sister company Fowlerex to fabricate a customised wet scrubber system to support a client’s pilot mineral processing plant in Australia. 

Our role was to bring that design to life – delivering a precision-built system that met the client’s unique operational parameters and on-site installation requirements. The scope included the complete wet scrubber unit along with all supporting recirculation and supply pipework. 

Scrubbers play a vital role across many industries, helping businesses meet environmental compliance standards, improve air quality, and protect people and equipment from hazardous or corrosive substances. In this case, the system was designed to “scrub” exhaust air from the client’s pilot plant before it is released into the environment, ensuring strict environmental standards are met. 

The system’s fabrication required a high level of detail and accuracy to ensure seamless installation by the client. This pilot-scale unit will also act as a proof of concept for a potential full-scale plant in the future, with the scrubber’s performance helping inform the next stage of development. 

Outcome
Taurus delivered a robust, custom-fit scrubber system. The project demonstrates our capability to work closely with our sister companies to provide vertically integrated solutions, from process design through to final fabrication. With its tailored design and high-quality build, the system will support the client’s ongoing water and chemical treatment processes while ensuring environmental compliance.
