Page 3 Over 25 years of experience of engineering and extensive lab testing has gone into the design of your watermaker. In fact many industry standards are a result of innovations made by FCI Watermakers, including one‑touch commands, multiple station operation, remote system control, touchscreen displays, and automated pressure control.
Page 4: General
The term system will be used throughout this manual, and it generally refers to the FCI Watermakers System. Reading this manual in its entirety will familiarize you with the system and the operation of its components. By understanding the system in its entirety, one can readily operate and diagnose problems.
Page 5: Glossary Of Terms
GLOSSARY OF TERMS Following terms are helpful in becoming familiar with a FCI Watermakers Reverse Osmosis System. BOUNDARY LAYER / CONCENTRATION POLARIZATION When water permeates through the membrane, nearly all the salt is left behind in the brine channel. In any dynamic hydraulic system, the fluid adjacent to the wall of the vessel is moving relatively slow.
