Sand Filtration
Granular media filtration for suspended solids and turbidity control.
Water-system note: treatment requirements depend on source water, intended use, equipment, permits and local rules. Real systems require qualified design, operation and laboratory verification.
What this topic covers
Granular media filtration for suspended solids and turbidity control.
Core water-treatment ideas
Sand filters retain particles within and on the media bed.
Pretreatment can improve performance where very fine colloids otherwise pass through.
Filtration does not remove most dissolved ions.
Important limits
Filter loading changes pressure loss and can reduce effective flow or quality.
What to monitor
Monitoring upstream and downstream quality provides evidence that the filter is doing its job.
Lifecycle perspective
Filter housings and pressurized systems require equipment-specific safe maintenance procedures.
