SWT Lateral with 3 Slot Widths
 
 
SWT LATERAL CONFIGURATION
SWT designs laterals for many types of distribution systems to significantly improve efficiencies and performance in filter media or resin beds. We will recommend materials of construction, hub design, and lateral configurations best suited to your system requirements.
• Efficiencies up to 40 percent better than standard laterals
• Reduced regenerant consumption
• Eliminate dead zones and channeling
• 100% non-corrosive materials
• Made in USA
SWT designs laterals to minimize dead zones in the media bed and to maximize the efficiency of the total area of the media bed.
When configuring SWT machined slotted laterals, the following criteria must be considered.
