Accu-Tab Tablets are safer, easier to handle and have a much more consistent delivery of chlorine than any other method used today.

I. PPG Accu-Tab Tablets vs Granular Chlorine

Characteristics	SES Accu-Tab Tablets	Granular Chlorine
Safety	Easy to handle; no spills; convenient 55 lb drums	Airborne dust particles; easy to spill on petroleum base products, causing fire
Material Compatibility	Self-buffering, scale inhibitor added to protect pipes and equipment from clogging	Inconsistent strength; calcium scale build-up on pipes
Convenience	55 lb pail of tablets; easy to handle; only add tablets once per week	100 lb containers are hard to maneuver; daily dosage needed
Chlorine Levels	Delivers precise, controlled, steady chlorine levels	Uncontrolled chlorine levels; cannot sustain any consistent ppm level
Chlorine Strength	Guaranteed 65% available chlorine	Inconsistent chlorine levels with many impurities remaining
Chlorine Delivery Control	Consistent strengths make for easy, reliable delivery	Manual dosing makes for inconsistent chlorine levels
Certifications	NSF Stds 60 & 61; USDA; AWWA Std B-300; EPA registered; Kosher approved	Must be certified by specific application

II. PPG Accu-Tab Tablets vs Chlorine Gas

Characteristics
SES Accu-Tab Tablets
Chlorine Gas
Safety
Easy to handle; no spills; no process safety management required
Major gas leak concerns; strict process safety management required
Charging Chemical Easy to add tablet; 1 person only 2 trained people needed; breathing protection required
Material Compatibility Self-buffering (calcium) less corrosive to equipment Low pH; very corrosive
Convenience 55 lb pail of tablets is easy to handle Dangerous; hard to maneuver cylinders; special training required to handle
Effect on pH pH (10.5) reduces acid usage for pH control by 50% or more Very low pH - requires large amounts of soda ash for pH control
Water Balance Chemicals SI tablets provide scale inhibitors to keep water lines & equipment clean Requires regular application of extra calcium and alkalinity additives
Chlorine Strength Small change over a full year Consistently 100% chlorine
Chlorine Delivery Control Consistent strength makes for easy, reliable delivery Troublesome regulators needed; difficult to automate delivery
Storage Convenience 55 lb pails stacked 3-high uses the same space as a 150 lb cylinder; no separate room required Separate room with special access required; fans and scrubbers also needed
Auxillary Equipment No moving parts in chlorinator itself Eductors, regulators; both have small orifices prone to plugging
III. PPG Accu-Tab Tablets vs Liquid Bleach (Sodium Hypochlorite)
Characteristics
SES Accu-Tab Tablets
Sodium Hypochlorite
Safety Easy to handle; no spills; no process safety management required Spill and leak concerns
Water Appearance Typically more sparkling due to calcium presence Cloudy as a result of high total dissolved solids (TDS)
Material Compatibility Self-buffering (calcium) less corrosive to equipment High pH causes metal discoloration to aluminum chillers
Convenience 55 lb pail of tablets; 400 lb bulk bags Hard to maneuver drums; small volume carboys; large bulk storage tanks
Effect on pH Lower pH (10.5) reduces acid or CO2 usage for pH control by 50% or more High pH requires more acid or CO2 pH control
Water Balance Chemicals SI tablets provide scale inhibitors to keep water lines and equipment clean Application of additional scale inhibitors are required regularly to balance water
Concentration 65% available chlorine 10% - 12% available chlorine
Maintains Chlorine Strength Small change over a full year Significant loss in just 1 week
Control of Chlorine Delivery Consistent strength makes for easy, reliable control Ever-changing strength makes control difficult
Storage Convenience Chlorine equivalent of 55 gallon drum of bleach in only a 6 gallon pail; 400 lb bag (size of 55 gallon drum) is equal to 400 gallon tote Drums or bulk tanks require space and possibly containment pad
Auxillary Equipment No moving parts in chlorinator itself; systems use industrial duty multistage centrifugal pumps with backup High maintenance of metering pumps is required
