need by tuesdayQuestion 1 1. Consider that you are treating a liquid phased waste stream with high concentrations of heavy metals in solution. You need to precipitate the heavy metals out of the solution in order to continue your treatment process. Describe your decision to either increase the pH or decrease the pH of the wastewater treatment system in order to effectively precipitate the heavy metals. Be diligent to defend what you suggest. Your response should be at least 200 words in length. Question 2 1. Discuss the techniques of coagulation, flocculation, and sedimentation as they relate to an engineered precipitation process for wastewater treatment. Your response should be at least 200 words in length. Question 3 1. Discuss the aspects of a chemical flocculation process design that must be considered during the engineering process. Your response should be at least 200 words in length. Question 4 1. Discuss the aspects of a secondary circular clarifier process design that must be considered during the engineering process. Your response should be at least 200 words in length.
