Drinking Water

WHO estimates that, in India, about 38 million people are affected by waterborne diseases each year, of which over 75% are children; 780,000 deaths are attributable to contaminated water and more than 400,000 can be attributed to diarrhea alone. India ranks a dismal low 120th out of 122 nations for its water quality and 133rd out of 180 nations for its water availability. Keeping in mind the above points; following problems are commonly faced by our current drinking water facilities

  • Traces of inorganic contaminants(As, Cr, Mn, Fe, etc)
  • DBP formation due to Chlorine (THM, HAA, etc)
  • Traces of organic contaminants
  • Endocrine disruptors ( DDT, Oxybenzone, Atrazine, etc)
  • Tastes and odours
  • Improper Disinfection( Presence of E. Coli, Cryptosporidium, Salmonella, Streptococci etc)
  • Color

Oxidation

  • COD/TOC
  • Increased DO so that no anaerobic condition is generated
  • Fe/Mn
  • Hydrogen Sulfide
  • Taste and Odor
  • Color
  • Specific Chemicals (Endocrine Disruptors etc)

Disinfection

  • Bacteria (The subsequent inability to divide and form colonies.)
  • Virus (The inability of the microorganism to form plaques in host cell.)
  • Parasites (The inability to replicate.)

Effect on Flocculation

  • Less chemical coagulant
  • Lower solids handling
  • Lower turbidity and particles
  • Longer Run Time
  • Less Backwashing

Pre-Treatment using Ozone does the following

  • Remove pathogens thus reducing challenges at final disinfection especially Cryptosporidium which is highly resistant to chlorination
  • Make the water more responsive to final disinfection by reducing chlorine demand and removing constituents of TOC- turbidity, color, DOC, endocrine disruptors.
  • Reduce the probability of THM by-product formation by removing precursors to its formation in the initial stage itself.
  • Longer Run Time
  • Less Backwashing
