SLOW PHOS Bulk Phosphate (5 lb.)

SLOW PHOS Bulk Phosphate (5 lb.)

$ 59.40

Ø Scale Prevention
Used to sequester hardness, inhibit precipitation, and 
formation of deposits. 
Ø Corrosion Inhibition
Used to form a protective coating on metal surfaces and 
provide corrosion protection against acidity, alkalinity, and 
many other mineral salts which may lead to the "rusting 
out" of water system pipes and equipment. 
Ø Iron Control 
Used to sequester dissolved iron up to 10 ppm and 
prevent the iron from precipitating, staining, 
discoloring, and distasteful flavor. 
Ø Convenience 
Offers operator convenience in feeding; only requiring 
addition of the product at monthly or quarterly 
intervals; expensive proportioning and feeding 
equipment is not required. 
SLOW PHOS can be fed at different concentrations in 
order to fit particular treatment situations or requirements. 
Normally a concentration of SLOW PHOS at threshold 
levels of 0.5-5.0 ppm polyphosphate will inhibit scale and

1. Start with a clean system. Drain and flush the entire 
system and remove any scale or debris present. 
2. Determine the amount and type of SLOW PHOS 
required. For most water, 0.5 to 1.0 pounds per ton of 
refrigeration is sufficient. Use 5.0 to 10.0 pounds of 
beads per feeder. The feeder should be placed in an 
area where there is good water flow. 
3. A proper bleed off system is absolutely essential for 
proper maintenance of concentrating recirculating 
water systems. This prevents the build up of mineral 
salts on equipment surfaces. 
4. To increase polyphosphate levels and feed rate, use 
multiple phosphate cartridges or larger feeder.
