When industrial systems stall due to coolant clogs, wastewater buildup, or sludge overflow, productivity suffers. These issues often arise before any obvious warning signs. That’s where industrial filtration systems play a critical role, keeping operations smooth by maintaining fluid quality, preventing blockages, and reducing unnecessary downtime. Whether you’re dealing with wastewater treatment, coolant recycling, or sludge removal, having the right filtration setup can make a measurable difference in performance. The following real-life examples show how Interfil’s specialised filtration solutions have helped clients across sectors maintain output, extend equipment life, and improve operational efficiency.
Steel Rolling Plant
Running a rolling mill around the clock requires coolant that can remain clean at high volumes. That’s not possible with manual systems or standard filters that clog under load.
The Hoffman filter is designed to handle flow rates from 6,000 to 18,000 litres per minute in high-speed sheet and coil lines. It continuously removes fine metal swarf and foreign matter from the coolant, keeping the system clear and reducing heat build-up across the machinery. Operators using the Hoffman filter report fewer coolant changes, less abrasive wear, and more consistent surface finishes. Stabilising coolant flow across shifts also helps reduce thermal fluctuations and unexpected wear, both key factors in keeping production on schedule.

Waste Services Recycling Plant
Wash bays that handle trucks or machinery used in waste and construction services often recycle tens of thousands of litres of water per day. This water picks up oil, soil, and road debris that, if left unfiltered, can lead to spray system blockages, water quality issues, and downtime between cycles.
The RF6/300 sludge dewatering system is designed to manage this load, filtering up to 15,000 litres per hour. Keeping contaminants out of spray nozzles and storage tanks, it removes solids and suspended waste so that water can be reused reliably throughout the day.
Some high-use sites even have a daily reuse volume that exceeds 100,000 litres, with filtration and productivity improvements closely tied to the quality of the treated recycled water onsite.
Avoiding the disposal of contaminated water also helps sites meet environmental expectations. CSIRO research highlights how industrial facilities benefit from keeping treated water in circulation by lowering both environmental risk and infrastructure strain.

Having Trouble Matching the Right Filter?
Frequent clogs or unstable flow often signal that the filter in place isn’t well-matched to your industry. Check out Interfil’s sludge dewatering systems and coolant filtration products, designed to meet demands across fluid types, pressures, and operational conditions.
Centrifuge for Vibrating Finishing System
In polishing and vibratory finishing systems, clean water is required to carry abrasives and remove fine particles as the media breaks down. Without filtration, those particles accumulate quickly and form a slurry that settles in tanks, clogs moving parts, and blocks outlets over time.
With a flow capacity of up to 60 litres per minute, the Interfil IC45AV Centrifuge is built to remove ceramic residue before it reaches pumps or discharge points. In consultation with our team, many sites also add a small dose of coagulant once a week to thicken the waste for easier removal and reduce the frequency of bin changes.
Furthermore, if ceramic waste reaches the sewer or bypasses filtration, sites may face both downtime and fines for improper discharge. With the centrifuge in place, the system runs more efficiently, and polishing results stay consistent over longer cycles. This video shows how the IC45AV Centrifuge prevents fines from entering discharge lines here.
Oil Skimmer BS2000
In engine bays, washdown areas, and water catchments, floating tramp oil gradually builds into a surface layer that’s difficult to break up. Left untreated, it causes odours, supports bacterial growth, reduces the quality of recycled water, and risks non-compliance.
The Interfil BS2000 Belt Oil Skimmer collects up to 5 litres of surface oil per minute. It’s commonly used across industrial yards, workshops, and wash pits where oils collect in storage ponds or tanks. By removing the oil before it spreads or emulsifies, the skimmer makes reuse more viable and reduces chemical input further downstream.

When Filter Choice Slows Everything Dow
Most industrial filtration issues don’t start with neglect. They start when the system isn’t designed for the volume or type of waste it’s handling. At Interfil, we work directly with operators to pinpoint where media filters are falling behind: where ceramic fines slip through, tramp oil resurfaces, or recycled water no longer meets basic quality standards.
