Sample interview questions: How would you handle a situation where a water treatment system is experiencing excessive organic matter levels?
Sample answer:
Steps to Handle Excessive Organic Matter in Water Treatment Systems:
-
Identify Source: Determine the potential source of the organic matter, such as decaying vegetation, faulty septic systems, or industrial discharge.
-
Assess System Capacity: Evaluate if the water treatment system is adequately sized to handle the current organic matter load. Upgrade or expand the system as necessary.
-
Mechanical Filtration: Implement mechanical filtration units, such as cartridge filters or granular media filters, to remove larger organic particles.
-
Coagulation and Flocculation: Introduce coagulants (e.g., alum) and flocculants (e.g., polymers) to agglomerate organic matter into larger particles for easier removal.
-
Sedimentation or Clarification: Use sedimentation tanks or clarifiers to settle out suspended organic matter.
-
Activated Carbon Adsorption: Utilize activated carbon filters to remove dissolved organic compounds by adsorption.
-
Oxidation: Deploy oxidation processes, such as ozone … Read full answer
