Features
Features & Benefits
- Carbon or stainless-steel housings Suitable for use with sand, DMI-65, and similar granular solids filtration media
- Skid-mounted units with forklift pockets for easy offload and relocation
- Automated backwash controllers with adjustable time- or differential pressure based backwash setpoints
- Three-way valves allow for backwash and forward flow without flow adjustment
- Filter influent and effluent pressure gauges enable easy differential monitoring
- Parallel operational configuration
- 8-pronged hub and lateral distribution systems to optimize filter area use and prevent quiet zones
- 110 VAC power requirement
Installation, Startup & Operation
The SF236, SF348, SF448, and SF454 sand filter housings are shipped as skids with interconnecting piping so the pods operate in parallel. The systems
are modular and require minimal field assembly and site connections.
Evoqua can provide a total service package that includes optional polymer pretreatment, settling, and post-filtration bag filters. Evoqua also uses OSHAtrained personnel, providing onsite system operation and maintenance.
Loadings
Sand filters are designed to remove suspended solids at higher loadings than those suitable for bag filters.
Systems with suspended solids loadings greater than 100 mg/L or relatively large particle sizes (>50 micron) commonly use self-backwashable sand filter units in order to prevent solids intrusion on water discharge locations or contamination of downstream treatment technologies.
In order to determine whether sand filters are suitable for each process location, Evoqua has laboratory capabilities, including turbidity measurement, particle size screening, and bench-scale testing of turbidity removal. In pilot and full-scale operations, sand filters are commonly used in conjunction with bag filters, settling tanks, and/or injection polymers tailored to meet site characteristics.
