Page 4: Introduction
Electrolysis with Water Flow The JOWA Ag-S electrode unit consists of two high purity (99.99%) silver plates. The water passes through the center of the electrode and between the two silver plates. The released silver ions, following the current direction between the plates, are forced by the water to flow out of the electrode chamber and into the piping system. - Page 5 Today silver is used in thousands of products to prevent biological growth. The JOWA Ag-S can have the concentration of silver ions set for any value between 0.025 mg/l (25 ppb) and 0.10 mg/l (100 ppb). The most common settings are either 0.04 mg/l (40 ppb) or 0.10 mg/l (100 ppb) silver.

Page 8: Treatment Of Water
Pressure for the Ag-S is provided by the hydrophore pump. The Ag-S unit doses silver into the branch line. This branch line is then directed back to the ship’s storage tank where the silver ions can treat the entire ship’s fresh water supply. -
Page 9: Direct Flow Mode
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. -
Page 10: Installation
Installation Mounting The JOWA Ag-S consists of a standard cabinet with all the electronics, an electrode chamber made with high grade electro-polished stainless steel, shut off valve, flow setting valve with flow indicator, flow switch, and two ball valves to isolate the chamber. -
