Iron in Your Water Supply WQP Water Quality Products

When iron is dissolved in water you cannot see it. Iron normally wants to revert back to its natural state as iron ore. Iron very easily comes out of solution and precipitates to a solid particle of ferric hydroxide [Fe (OH)3] often referred to as “red water iron.” Simple changes to the water supply such as temperature, pressure or even a
