Force Field Analysis | ASQ

Force Field Analysis. Quality Glossary Definition: Force field analysis. Force field analysis is a basic tool for root cause analysis that can help you take action once the root cause has been identified. The technique is based on the assumption that any situation is the result of forces for and against the current state being in equilibrium.

Iron removal by physical chemical way

Pourbaix diagram of Iron. However ground waters are naturally anaerobic: so iron remains in solution and therefore it is important to remove it for a water use. The elimination of the ferrous iron, by physical-chemical way, is obtained by raising the water redox potential by oxidation thanks to oxygen of the air and this by simple ventilation.
