In a wet well, electrode devices can be rendered ineffective due to which issue?

• A. They could use too much power
• B. Grease and fats will coat and cause it to lose conductivity
• C. Better in a big well
• D. They produce stronger readings

Answer: (B)

Electrode readings depend on good electrical contact with the wastewater. When grease and fats are present in a wet well, they can coat the electrodes and form an insulating layer. That coating blocks conductivity and prevents accurate sensing, making the electrode device unreliable or ineffective.

Other ideas don’t fit the issue: simply using too much power doesn’t cause the coating problem, a bigger well doesn’t inherently improve or fix fouling, and the notion of stronger readings contradicts the actual effect of a coating, which would blunt or distort signals. Regular cleaning to remove grease buildup helps keep the electrodes responsive.
