Rotary Drum Filters vs. Bead Filters
Why Switch to Bead Filters?
For industrial and commercial filtration, drum filters aren’t your only option – bead filters can be a better choice for your application.
Compared to rotary drum filters, AST bead filters can offer:
- Lower per-unit cost for equivalent flow rates
- Full, turnkey solution in one unit
- Lower energy consumption
- Superior solids capture
- Finer solids capture
- Integrated bio-filtration
- Zero water loss
- Smaller footprint
- Easier cleaning (no more screen filter clogs)
- Less downtime and easier maintenance
No More Drum Screen Filter Cleaning
AST filters feature an incredibly easy, fast, and clean backwash function. Compared to the cumbersome cleaning process that can be required with a rotary drum filter, bead filters are painless.
Because the backwash process is so fast, bead filters also significantly reduce the downtime and maintenance time compared to equivalent drum filters.
Eliminate Redundancies
With an AST bead filter system, you can reduce the complexity of your filter solution and remove unnecessary or redundant components. A bead filter system can eliminate the need for moving bed bioreactors (MBBR) or other bio-filtration, as well as low head oxygenators that are often paired with a drum filter.
Add-on Clarification
If you already have a reliable drum filter solution, AST bead filters can also be a simple way to add additional and more thorough clarification and water polishing to your filtration process.
Unit Flow Rate Price Comparison
Compared to drum filters, a bead filter offers competitive pricing, often resulting in lower overall costs with equivalent flow rates.
