Sample interview questions: Are you familiar with different types of water purification systems and their installation requirements?
Sample answer:
Yes, I am familiar with different types of water purification systems and their installation requirements.
Types of Water Purification Systems:
-
Reverse Osmosis (RO): Removes up to 99% of contaminants through a semipermeable membrane. Requires pretreatment and a separate storage tank.
-
Ultraviolet (UV): Disinfects water by irradiating microorganisms with UV light. Requires an electrical connection and regular bulb replacement.
-
Distillation: Boils water to produce clean steam that is condensed back into pure water. Requires energy consumption and produces a limited amount of water.
-
Activated Carbon Filtration: Removes organic contaminants, chlorine, and odors by passing water through carbon-based filters. Requires regular filter replacement.
-
Ion Exchange: Exchanges unwanted ions (e.g., calcium, magnesium) with desired ions (e.g., sodium). Requires periodic regeneration of the resin bed.
Installation Requirements:
-
Water source: Determine the type of water supply (e.g., city, well, tank) to select the appropriate system.
-
Water quality: Analyze the water to identify the specific contam… Read full answer
