Treating Drinking
Water
 The
chemical makeup and varied benefits of the Accu-Tab®
tablet chlorination system provide a remarkable solution for drinking
water chlorination. Specifically, PPG has answered the challenge
of providing an easy-to-use and safe method of chlorination. Below
are some key points about the product and its impact on the water
industry:
- Chlorination is recognized and
widely accepted as the effective method of disinfecting drinking
water. 98% of drinking water is chlorinated.
- Today, many companies and municipalities
are looking for alternatives to chlorine gas cylinders and liquid
bleach (sodium hypochlorite) due to safety & handling concerns
and are choosing PPG calcium hypochlorite as a viable alternative.
- Accu-Tab® tablet
chlorination systems provide a consistent and accurate method
of drinking water chlorination.
- NSF 60 and 61 Listed AWWA -
B300

Customer Case Study
Company Profile:
Water district in south eastern U.S.
Provides drinking water to 13,000+ households, or 36,000 people.
The district pumps approximately 4.5 million gallons of water
a day; peak days average 6.5 million gallons. Total service area
relies on 450 miles of pipe to reach 140 square miles.
Situation Analysis:
The water district is a consecutive water system, meaning it purchases
its finished water supply primarily from the nearby water system.
However, its customer base has continued to expand to the outer
limits of its service area, and the chlorine residual has, on
occasion, fallen short of the required levels needed to maintain
water quality to some outlying areas. As such, it actively sought
a system to provide booster chlorination to those outer limits.
Initially, the water district
considered three methods of booster chlorination:
When reviewing the methods,
the final solution had to meet all three of the water disctrict's
criteria:
Both chlorine gas and liquid
bleach scored low marks for ease of operation and safety, as far
as the water district was concerned. Because both are considered
volatile forms of chlorine, the water district believed it would
not only put its employees and the public at risk, it would spend
more time and money in safety equipment and safety training. The
decision to test PPG's calcium hypochlorite chlorinating system
was unanimous.
Solution:
The water district and two neighboring water districts just completed
a 90-day test of the PPG system -- the first system of its kind
to be tested in the state. The test was favorable, and, as such,
the water district is recommending the system be approved for
use throughout the state.
Overall, the PPG system provided
consistent chlorine delivery throughout the area being treated
-- even the outer limits they originally sought to reach. Additionally,
the PPG system proved to be safe and user-friendly, as well as
affordable.
Company Quote:
"We considered chlorine gas, but our concern was safety.
Then we looked at liquid bleach and safety was also a concern.
When we factored in costs, we decided it would be to our advantage
to use the PPG system. In fact, we think the system has great
potential for use throughout the entire state."
