SWIMMING POOL WATER DISINFECTION
For a new pool or spring start-up, superchlorinate with
107 to 213 fl. oz. of product for each 10,000 gallons
of water to yield 5 to 10 ppm available chlorine by
weight. Check the level of available chlorine with a test
kit. Adjust and maintain pool water pH to between 7.2
to 7.6. Adjust and maintain the alkalinity of the pool
to between 50 to 100 ppm. To maintain the pool, add
manually or by a feeder device of 22 fl. oz. of this
product for each 10,000 gallons of water to yield an
available chlorine residual between 0.6 to
1.0 ppm by weight. Stabilized pools should maintain a
residual of 1.0 to 1.5 ppm available chlorine. Test the
pH, available chlorine residual and alkalinity of the
water frequently with appropriate test kits. Frequency
of water treatment will depend upon temperature and
number of swimmers. Every seven days, or as necessary,
superchlorinate the pool with 107 to 213 fl. oz. of
product for each 10,000 gallons of water to yield 5 to
10 ppm available chlorine by weight. Check the level
of available chlorine with a test kit. Re-entry into treated
pools is prohibited above levels of 4.0 ppm due to risk
of bodily harm. At the end of the swimming pool season
or when water is to be drained from the pool, chlorine
must be allowed to dissipate from treated pool water
before discharge. Do not chlorinate the pool within
24 hours prior to discharge.
Winterizing Pools – While water is still clear and clean,
apply 6.5 fl. oz. of product per 1000 gallons, while
filter is running to obtain a 3.0 ppm available chlorine
residual, as determined by a suitable test kit. Cover pool,
prepare heater, filter and heater components for winter
by following manufacturers instructions.
SPAS, HOT-TUBS, IMMERSION TANKS, ETC.
Spas/Hot Tubs – Apply 11 fl. oz. of product per
1,000 gallons of water to obtain a free available
chlorine concentration of 5.0 ppm, as determined by
a suitable chlorine test kit. Adjust and maintain pool
water pH to between 7.2 and 7.8. Some oils, lotions,
fragrances, cleaners, etc. may cause foaming or
cloudy water as well as reduce the efficiency of the
product. To maintain the water, apply 11 fl. oz. of
product per 1000 gallons of water over the surface to
maintain a chlorine concentration of 5.0 ppm. After
each use, shock treat with 17 fl.oz. of this product
per 500 gallons of water to control odor and algae.
Re-entry into treated spas is prohibited above levels of
5.0 ppm due to risk of bodily harm. During extended
periods of disuse, add 6.5 fl. oz. of product per
1,000 gallons of water dailyto maintain a 3.0 ppm
chlorine concentration.
Hydrotherapy Tanks – Add 2.5 fl.oz. of this product per
1,000 gallons of water to obtain a chlorine residual of

1.0 ppm, as determined by a suitable chlorine test kit.
Pool should not be entered until the chlorine residual
is below 3.0 ppm. Adjust and maintain the water pH to
between 7.2 and 7.6. Operate pool filter continuously.
Drain pool weekly, and clean before refilling.
SEWAGE AND WASTEWATER EFFLUENT TREATMENT
The disinfection of sewage effluent must be evaluated
by determining the total number of coliform bacteria
and/or fecal coliform bacteria, as determined by the
Most Probable Number (MPN) procedure, to ensure that
the chlorinated effluent has been reduced to or below
the maximum permitted by the controlling regulatory
jurisdiction.
On the average, satisfactory disinfection of secondary
wastewater effluent can be obtained when the
chlorine residual is 0.5 ppm after 15 minutes of contact.
Although the chlorine residual is the critical factor in
disinfection, the importance of correlating chlorine
residual with bacterial kill must be emphasized. The
MPN of the effluent, which is directly related to the water
quality standards requirements, should be the final and
primary standard and the chlorine residual should be
considered an operating standard valid only to the
extent verified by the coliform quality of the effluent.
The following are critical factors affecting wastewater
disinfection:
1.
2. Contacting: Upon flash mixing, the flow through the

SEWAGE AND WASTEWATER TREATMENT
Effluent Slime Control – Apply a 100 to 1,000 ppm
available chlorine solution at a location which will allow
complete mixing. Prepare this solution by mixing 22 to
213 fl. oz. of this product with 100 gallons of water. Once
control is evident, apply a 15.0 ppm available chlorine
solution. Prepare this solution by mixing 3.5 fl. oz. of this
product with 100 gallons of water.
Mixing: It is imperative that the product and the
wastewater be instantaneously and completely
flash mixed to ensure reaction with every chemically
active soluble and particulate component of the
wastewater.
system must be maintained.
extremely dependant on response to fluctuating
chlorine demand to maintain a predetermined,
desirable chlorine level. Secondary effluent should
contain 0.2 to 1.0 ppm chlorine residual after a 15
to 30 minute contact time. A reasonable average of
residual chlorine is 0.5 ppm after 15 minutes
contact time.
