FAQ

To assist procurement managers and site engineers in their evaluation process, we have compiled detailed answers to the most common technical inquiries regarding our rotary drum filters.

How does the automatic backwash system determine when to clean the mesh?

The system is governed by a highly sensitive liquid level induction control. As suspended solids accumulate on the mesh, the water flow is restricted, causing the internal water level to rise. Once the water hits a pre-set sensor threshold, the PLC instantly activates the high-pressure backwash pump and rotates the drum, blasting the debris into the collection trough without halting the overall filtration process.

Can this filter handle high-salinity environments like seawater aquaculture?

Absolutely. For highly corrosive environments such as Recirculating Aquaculture Systems (RAS) or coastal desalination pre-treatment, we upgrade the standard SS304 construction to premium SS316L stainless steel. Additionally, critical internal fixtures are crafted from advanced corrosion-resistant engineering plastics, ensuring decades of rust-free operation.

What is the typical maintenance schedule for the filter screen?

Thanks to the continuous self-cleaning mechanism, routine maintenance is exceptionally low. We recommend a visual inspection of the mesh and nozzles once a month. Because we utilize a quick-release modular screen design, if a section of the mesh is accidentally damaged by sharp debris, a single operator can replace that specific panel in under 15 minutes, drastically reducing maintenance labor.

Is it possible to integrate this equipment into an existing SCADA system?

Yes, integration is seamless. Our filters come equipped with advanced PLC control panels that feature standard industrial communication protocols. This allows your central SCADA system to monitor real-time data such as motor status, backwash frequency, and fault alarms, enabling centralized, smart facility management.

How do I determine the correct model and mesh size for my facility?

Proper sizing depends on three primary factors: your peak hourly flow rate (m³/h), the concentration of Total Suspended Solids (TSS), and the target effluent clarity. Our engineering team provides comprehensive consultation services. By analyzing your specific water quality reports, we will recommend the optimal model (from RBWL 1 to RBWL 6) and the precise mesh density (60-250 mesh) to guarantee maximum efficiency and cost-effectiveness.
