The EES
Model 1000 or 1001 Tablet Feeder is a complete, one-piece system for highly reliable
disinfection of treated effluent from any sewage plant having a designed capacity of up to
50,000 gpd. Two tablet feeders in parallel will handle plants with capacities as high as
100,000 gpd. The tablet feeder is used in conjunction with SANURIL tablets, a disinfecting
agent that provides a chemically stable source of chlorine for wastewater disinfection.
Two models are available: Model 1000 with a six-inch pipe inlet, or Model 1001 with
solid inlet end for easy field adaptation to the outlets of existing plants. Either tablet
feeder can be installed in existing treatment plants where wastewater chlorination is
being added or to replace troublesome, unreliable or complicated chlorination systems.
Either is equally suitable for factory assembly into new package plants. |

Superior Performance at a Lower Cost |
- Better Performance - The
entire plant flow passes through the chlorinator where thorough mixing of wastewater with
a controlled amount of chlorine takes place. This means more effective bactericidal action
and less bacteria regrowth.
- Low Initial Cost - In
addition to low investment in the Mini-San Chlorinator, savings are compounded because no
pumps, mixing tanks or costly control devices are required as with most other chlorination
systems
- Simple, Low-Cost Installation - One-piece chlorinator construction requires only inlet piping. No electrical power,
wiring, bypasses or other piping required.
- Lower Operating Costs -
Chlorinator operates up to 60 days on a single charge. No time-consuming premixing of
chemicals or costly cylinder handling. Recharging SANURIL 115 tablets is quick and easy.
No costs for electrical power or auxiliary power.
- Maintenance-Free Operation - No tanks, pumps, cylinders, external control devices or other moving parts to break
down. System is non-mechanical and rust and corrosion proof.

Operating Principle |
| The EES
Tablet Feeder is a one-piece system which operates on the flow-through principle to
provide constant, controlled dosage of chlorine to the effluent of wastewater treatment
plants.
The entire flow of treated wastewater passes into the tablet feeder through the
inlet pipe. As the stream of water flows past the feed tubes containing SANURIL tablets,
active chlorine is released into the wastewater by the dissolving action of the water
stream contacting the tablets.
Each tablet feeder is furnished with a selection of weir plates, with weirs ranging in
size from 1 to 3 inches in width for insertion at the outlet end to control the internal
water level, depending upon plant capacity and the residual chlorine required. Each weir
plate is calibrated, enabling the user to tell, instantaneously, the flow rate of the
plant. The weir in turn automatically controls the chlorine concentration regardless of
surges of wastewater flow. As the incoming flow rate increases, the water level in the
tablet feeder rises, immersing a greater number of SANURIL tablets. When the incoming flow
decreases, the water level in the tablet feeder drops, exposing fewer tablets to the
water. Since the amount of SANURIL tablets dissolved depends on the number of tablets
immersed in the water, the chlorine concentration remains constant regardless of the rate
of water-flow through the tablet feeder.
The chlorinated wastewater then
flows into the chlorine contact tank where it is held for the required time to permit
effective bacteria killing action.
Each tablet feeder is furnished with four feed tubes. The number of tubes to be filled
with SANURIL tablets is determined by the average daily flow rate and the required
residual chlorine content or dosage. |
Installation |
| The EES
Tablet Feeder is designed for installation in any sewage plant having sufficient space to
permit mounting. The tablet feeder can be located on or preceding the chlorine contact
tank as near as possible to the inlet so as to channel entire plant flow through the
tablet feeder before it enters the chlorine contact tank. |
Specifications |
| The
tablet feeder is made of tough, corrosion resistant rotomolded polyethelene and polyvinyl
chloride. Compact and easy to handle, the tablet feeder measures 26 inches long, 18 inches
wide, and 16 inches deep. The feed tubes are 24 inches long with an outside diameter of 3
1/2 inches. Each tube hods 29 SANURIL tablets which measures 2 5/8 inches in diameter and
are 13/16 " thick. The Model 1000 has a 6" diameter inlet pipe size, the Model
1001 has a solid inlet end for easy field adaptation to the outlets of existing plants. |
Other Applications |
| In
addition to wastewater chlorination, the EES Model 1000 or 1001 tablet feeder can also be
used for dechlorination and the chlorination of drinking water. For dechlorination, the
Model 1000 or 1001 is used in conjunction with the EES D-CHLOR tablets. These tablets are
a sodium sulfite based formulation having compatible dimensions for use in the EES Model
1000 or 1001 tablet feeder.
For drinking water chlorination, the Model 1000 or 1001 is
used in conjunction with the EES AQUAWARD chlorinating tablets. The AQUAWARD tablets are a
calcium hypochlorite based formulation also having dimensions compatible for use in the
EES Model 1000 or 1001 tablet feeder. This system is ideal for open channel flow operation
and/or remote installations where other methods of disinfection are not practical or
economical. |
