Lecture #07- Mid-Ocean Ridges

Lecture #07- Mid-Ocean Ridges. Mid-Ocean Ridges (MOR). Mid-Ocean ridges are divergent plate boundaries; these are regions where plates move away from one another As you might imagine, they occur only between oceans and oceans (continents are not involved). Mid-Ocean Ridges.

Phosphorus Removal

Phosphorus Removal. The most common method to remove phosphorus from a waste stream is chemical precipitation. The common precipitating cations are Ca, Al and Fe. Calcium. Calcium is usually added as lime (Ca(OH) 2 ). The reaction is represented as:.
