Which of the following is not correct with reference to Bio-sand Water Filter? A. It deactivates or kills pathogens B. Sedimentation removes larger particles. C. Filtration removes smaller particles D. High-quality water is always assured Correct Answer D

  • Bio-sand Water Filter: It is a water treatment system adapted from conventional slow sand filters.
  • It does not always assure a high-quality water supply.
  • Primarily biological and physical processes are used for separation of the pathogen.
  • It kills pathogens and other germs present in water.
  • Sedimentation removes larger particles. Filtration removes smaller particles.

What is the role of ultraviolet (UV) radiation in the water purification systems? 1. It inactivates/kills the harmful microorganisms in water. 2. It removes all the undesirable odours from the water. 3. It quickens the sedimentation of solid particles, removes turbidity and improves the clarity of water. Which of the statements given above is/are correct? 
A rotary drum filter with 30% submergence is used to filter concentrated aqueous slurry of calcium carbonate containing 15lb of solids per cubic foot of water. The pressure–drop is 2011Hg. If the filter cake contains 50% mixture (wet basis), calculate the filter area required to filter 10 gal/min of slurry. The filter cycle time is 5 min. The specific cake resistance depends on the pressure–drop as: α (ft/lb) = α (Δp)0.26, where α = 2.90×1010 Viscosity of the filtrate = 6.72×10-4 lb/ft-s. Density of calcium carbonate = 168.8 lb/ft3. Neglect filter medium resistance.
