Automated workflow
Full automated side stream filtration and system cleaning
From continuous draw to automated cleaning and return, the skid operates autonomously to maintain water quality across the system lifetime.
Continuous Side Stream Draw
A fixed percentage of the main system flow is continuously drawn from a low-velocity point in the return pipework. This ensures representative sampling of debris and particulate from across the entire loop.
Magnetic Filtration Stage
Ferrous oxide (magnetite) and other magnetic debris are captured by a high-intensity rare-earth magnetic assembly. This is the primary defence against the black sludge that destroys seals, valves and heat exchangers.
Depth Media Filtration
Non-magnetic particulate passes through a depth-media cartridge rated from 5 to 100 micron depending on application. This removes sand, scale, installation debris and corrosion by-products.
Differential Pressure Monitoring
Integrated DP sensors continuously measure pressure loss across the filter element. As the media loads, the control system tracks performance and raises an alert when a change-out is required — no guesswork.
Automated Backwash & Cleaning
On preset intervals or DP thresholds the skid initiates an automated backwash sequence. The magnetic rod is cleaned in-situ and the media vessel is flushed to drain — all without interrupting system flow.
Clean Water Returned to System
Treated, debris-free water is returned to the main circuit at a point that promotes good distribution. The result is continuously improving water quality, reduced chemical demand and extended plant life.
System benefits
Healthier systems, lower lifetime costs.
Continuous side stream filtration removes the root cause of premature plant failure — delivering measurable improvements in water quality, energy efficiency and asset life.
Stop corrosion
Continuous removal of magnetite and oxygen-laden sludge halts the corrosion cycle inside closed loops.
Protect boilers and pipework
Cleaner system water means longer asset life for boilers, pumps, valves and heat exchangers.
Dark water to clear water
Visible improvement in water quality — black, sludge-laden circuits return to clean, clear condition.
Lower running costs
No filter bags or mixed media to swap out — eliminates the recurring consumables bill of bag filtration.
Restore plant efficiency
Removing fouling from heat transfer surfaces brings boiler and HX performance back to design duty.
Operates 24/7 unattended
Fully automated backwash and self-cleaning — no operator intervention, no system downtime.
Technical specifications
Engineered for continuous performance.
Every skid is built from robust carbon steel housings with SS304 screens, delivering reliable automated filtration with minimal water loss and uninterrupted system flow.
