The Clearwater Industries Model 522 Polymer Feed System is in essence two small make down units. The 817-gallon tank is split in two and is linked with a 4" ball valve. Each half has its own dry make down equipment and disbursement pump. This allows the consumer the ability to use both a dry cationic and dry anionic polymer simultaneously. This system is ideal for:

• Moderate to small applications that require two distinct dry chemicals
• Small Belt Presses and Clarifiers

Features:

• Can be "up and running" 1 hour after unloading
• Solution without the formation of "fish-eyes"
• Two stainless steel 110 lb. Hoppers (200 lb. Hopper optional)
• Variable speed screw feeder with solid shaft auger
• Low water pressure protection
• Fully automatic, continuous batching operation
• Two progressive cavity polymer disbursement pumps. Variable speed pump drives with 4-20 mA input. Maximum pump delivery is 15 gpm each
• Tank is constructed of rugged 1/2" polypropylene triple welded inside and out and is capable of holding 817 gallons of solution (408 gallons on each side)
• 3" square steel framework painted with aliphatic urethane epoxy paint, which yields a high chemically resistant finish that fades little under UV rays
• Single tank split design with internal baffle and weir is a simple design that assures proper mixing and aging of polymer
• Hand/Off/Auto switches provide manual or automatic sequencing
• Two stainless steel mixing shafts each turning two stainless steel 10" props for individual chemical mixing

Optional Features:

• Allen Bradley Panel View display allows the controller push button controlling options
• Wedgewood Auto Floc Controller adjusts polymer dosage depending on solid content in wastewater
• Multi-gang manifold allows polymer solution to be pumped to several different locations
• Remote speed pot allows controller to adjust polymer pump speeds while away from the unit

Utilities:

• One point electrical hook-up, 460/230 volt 3-phase, or 240/120 volt single phase. Customer to specify
• One point clean water hook-up, 1-1/4" line at 25 to 80 psi

Dimensions:

• Framework is 5'(W) x 9-1/2'(L) x 7'(H)
• Approximate shipping weight is 1600 lbs.
