We sell NSF Certified liquid chlorine and powder chlorine products
to meet compliance with government regulations and/or food processing
standards. The Buying Network sells complete systems from injection
pumps, tanks and engineers the system for you. We stock test strips and
test kits to assist in monitoring and regulating your chlorine levels.
Please contact for pricing on any of the below chlorine sanitation items:
*Dissolving 1.6 lbs of 65%
calcium hypochlorite powder into one gallon of hot water approximately
yields a 12% chlorine solution.
POTABLE DRINKING WATER
Acceptable chlorine levels for potable drinking
water ranges from 0.3 - 0.9 PPM. Most water district standards are
Household Bleach: To obtain 0.5 PPM dilution,
it takes 3 fl. oz. of 4% liquid household bleach for each 1,000 gallons
Commercial Bleach: To obtain 0.5 PPM dilution,
it takes 1 fl. oz. of 12.5% commercial liquid chlorine for each 1,000
gallons of water;
65% Powdered Chlorine: To obtain 0.5 PPM
dilution, it takes 3/8 oz. of 65% calcium hypochlorite for each 1,000
gallons of water;
FACTORY PROCESSING WATER
Acceptable chlorine levels for factory process water ranges from 3.0 - 9.0 PPM.
Dissolving 2.0 oz. of 65% calcium hypochlorite
powder in 10,000 gallons of water will impart approximately 1.0 PPM
Dissolving 3.75 oz of 65% calcium hypochlorite
powder in 1,000 gallons of water will impart approximately 5.0 PPM
CALCULATING INJECTION RATES - LIQUID CHLORINE
To calculate the amount of chlorine to inject to obtain a desired chlorine residual, use the following formula:
IR = 0.006 Q C / S
IR = Injection Rate (gallons / hr) Q = System Flow Rate in gallons per minute C = Desired Injection Concentration in PPM S = Strength of chlorine bleach being injected in whole number %.
EXAMPLE: You want to inject 15 PPM chlorine
into a 250 gallon per minute system, and you are using a 12%
sodium hypochlorite solution. The formula will tell you how many
gallons per hour of 12% bleach to add I order to achieve 15 PPM in a 250
gallon per minute flow:
IR = (0.006) (Q) (C) / (S) IR = (0.006) (250) (15) / (12) IR = 1.875 gallons per hour
SHOCK STERILIZING TANKS & WATER SYSTEMS
Tanks and potable water systems require sanitation
after repair. Before these systems are put back into service, they
need to be disinfected. This process is called
"super-chlorination". In order for "super-chlorination" to be
effective, a minimum chlorine concentration of 50 PPM and a minimal
contact time of four hours is required.
PROCEDURE 1. Finish tank / system repairs; 2. Hose down and flush tank / system to remove loose contaminants; 3. Drain water; 4. Obtain fresh bleach; 5. Fill tank / system to about ¼ full; 6. Calculate bleach to impart 50 PPM for entire system volume;
7. Pour bleach into tank / system; 8. Fill tank / flood system; 9. Open taps to vent air - to insure system is filled with chlorinated water; 10. Test chlorine residual at taps; 11. Maintain chlorine residual at 50 PPM; 12. Add additional bleach and open taps to circulate throughout system; 13. Dose additional chlorine to maintain minimum 50 PPM; 14. Maintain 50 PPM contact time for four hours; 15. Drain system, fill and flush with water; 16. Drain and refill & put system back into service
Calculations are considered an approximate starting
point only and are based upon using non-chlorinated water. A
chlorine test kit is recommended to confirm chlorine levels and for
making chlorine level adjustments.
