Filter Pretreatment
Protecting Filters with Upstream Clarification
Plate settler pretreatment reduces solids loading to sand, disc, and media filters — extending run times and cutting backwash frequency.
Filter Pretreatment
Granular media and disc filters perform best when influent solids are low and stable. High or variable solids loading shortens filter runs, increases backwash water use, and can cause turbidity breakthrough.
A plate settler ahead of filtration removes the bulk of suspended solids, delivering consistently low-turbidity feed. This extends filter run times, reduces backwash frequency, and stabilizes filtered water quality.
The compact plate-settler pretreatment stage is a cost-effective way to protect and de-bottleneck existing filtration without expanding the filters themselves.
Key Benefits
Longer Filter Runs
Lower influent solids extend time between backwashes.
Less Backwash
Reduces backwash water and energy consumption.
Stable Feed
Delivers consistent low-turbidity feed to filters.
