F2 JOWA Ag-S
Silver Ion Water Treatment System
Standard
6/32
The valve V01 is controlled by the Ag-S and will open when the unit is actively
producing Silver Ions. The water will then go through the silver chamber; in at the
bottom and out at the top. The flow switch FS01 will tell the system if there is water
flow going through the chamber.
The Ag-S can be controlled by a remote signal. A signal from a watermaker can start
the unit and the Ag-S can send a signal to the watermaker to stop if the Ag-S unit
stops. This can happen with certain error conditions.
The system can operate in a Volume mode where the User enters a known quantity
of water when bunkering water from shore or a known amount of water has been
produced.
3.2 Direct Flow Mode
If a storage tank is not available to support the recirculate mode the unit can be
setup in the Direct Flow mode and dose the Silver Ions into the stream only when
water is produced or flowing in the main line. In this mode the unit has a reduced
flow and PPB range. See Fig 5.1.2 Note that a 4 hour contact time is still required
for the Silver Ions to be effective.
3.3 Options
A flowmeter can be installed in the water production plant line. The Ag-S will
determine the correct dose of silver based on the flow signal from the meter. A
second flowmeter can also be installed if you want to monitor both bunker and
production water lines.
NOTE! An optional flowmeter (PN 92000-00023 or other
pulse output flowmeter) is required if the unit is to be run in this mode.
As an extra protection a shut off valve V02 can be installed on the main pipe to stop
the water flow from the watermaker or the bunker line. This is can be done to avoid
any non-treated water from being produced or bunkered. In the case of using this
valve with a watermaker there should also be a stop signal connected from the
Ag-S to the watermaker.
The standard Ag-S is designed to be hard wired to an electrical supply. An external
power switch can be install by the user or if desired an optional switch can be
mounted to the left side of the enclosure.
The system can be modified for non-standard installations. JOWA will give you
support when you have special installation requirements.
