Sewage/ Wastewater Treatment
By: Akshaya Madduru
The inventor of Eisenhower Matrix is Dwight David Eisenhower – an American army general and statesman who served as the 34th President of the United States from 1953 to 1961. His method helps us prioritize by urgency and importance.
ENVIRONMENT
These tasks are not important but they still need to be done. The question you have to address yourself: Who can do this for you?
What is the environmental impact of sewage treatment?
Introduction
Tasks that are not urgent nor important should be eliminated so you will not waste time doing them.
WHAT ARE THE EQUATIONS:
Net ionic equation:
the removal of Manganese(II):
Mn2+(aq) + Cl2(aq) → Mn4+ (aq) + 2Cl-(aq) : Mn4+(aq) + O2(g) → MnO2(s)
= Mn4+ was created in the product side, and makes insoluble precipitates, which caused problems. So to eliminate that, you have to add oxygen to balance out the Mn4+.
Net ionic equation:
3Fe2+(aq)+ MnO-4(aq) + 2H2O(l) → 3Fe3+(aq) + MnO2(S) + 4OH-(aq)
= Fe3+(aq) + 3OH-(aq) → Fe(OH)3(s)
= As you can see a precipitate is formed. and repetition of ions and elements on both sides did occur.
