RECHARGE SEQUENCE
The Klear-Flo II filter system is comprised of two individual pressure vessels each having plumbing connections providing a
means for installation into a continuously pressurized water system. The vessels are installed in series with the Oxidizer Ves-
sel positioned ahead of the Filter Vessel. A demand for treated water causes flow to occur through both vessels. Raw water
entering the filter is first oxygenated then filtered. This cycle of operation is referred to as SERVICE. Eventually the filter
system requires a recharge of oxygen and a thorough cleaning of the filtration media. This multi step process is referred to
as the RECHARGE SEQUENCE.
Each vessel is individually recharged in succession during a time period when treated water demand is low. The recom-
mended times for recharge are AM for the Oxidizer Vessel and AM for the Filter Vessel. The time intervals must be staggered
so each vessel has access to an adequate water supply. Each vessel is equipped with an adjustable calendar clock control-
ler capable of initiating the recharge sequence at a user-deterrnined schedule. (Refer to Determining a Recharge Schedule)
The following is a description of each step in the RECHARGE SEQUENCE.
The Oxidizer Vessel is sequenced first (Steps # 1 - 4) followed by the Filter Vessel (Steps # 5 - 7). Water pressure and flow is
available during all steps of the RECHARGE SEQUENCE, however the water quality may be unsatisfactory during this time
interval.
1.
FLUSH #1
- Raw water is by-passed directly to the Filter Vessel. The Oxidizer Vessel is repressurized with water
compressing the new air charge. The down flow of water is directed to the bottom of the vessel and discharged to
drain. The compressed air remains at the top of the Vessel.
2.
BACKWASH #1
- Raw water is by-passed directly to the Filter Vessel and is also directed into the bottom of the
Oxidizer Vessel. The top of the Oxidizer Vessel is vented to atmosphere and routed to a drain. The remaining air
charge is released. Simultaneously the trapped particles in the pH neutralizing granular filter media are removed by
a reverse flow of water and discharged to the drain.
3.
AIR INJECTION
- Raw water is by-passed directly to the Filter Vessel. All water is removed from the Oxidizer Vessel
and replaced with a fresh supply of air at atmospheric pressure. This process is accomplished with a venturi. There
will be a low flow of water to the drain.
4.
OXIDIZER RETURN TO SERVICE
- Oxygenated, pH neutral, filtered water is available for the recharge of the Filter
Vessel. There will not be a flow to the drain.
5.
BACKWASH #2
- Oxygenated, pH neutral, partially filtered water is by-passed directly to the Filter outlet and is
also directed into the bottom of the Filter Vessel. The top of the Filter Vessel is vented to atmosphere and routed to a
drain. Trapped particles in the granular filter media are removed by a reverse flow of water and discharged to the
drain.
6.
FLUSH #2
- Oxygenated, pH neutral, partially filtered water is by-passed directly to the Filter outlet.The down flow of
water is directed to the bottom of the vessel and discharged to drain. Remaining particles are flushed from
both Vessels.
7.
SYSTEM RETURN TO SERVICE
- Oxygenated, pH neutral, odor free, filtered water is available at the Filter System
outlet. There will not be a flow to the drain.
