POLLUTION
     

Industrial waste water:

  Industries discharge millions of gallons of effluent as hazardous toxic waste, full of color and organic chemicals from dyeing and finishing salts. Presence of sulphur, naphthol, vat dyes, nitrates, acetic acid, soaps, chromium com- pounds and heavy metals like copper, arsenic, lead, cadmium, mercury, nickel, and cobalt and certain auxiliary chemicals all collectively make the effluent highly toxic. Other harmful chemicals present in the water may be formaldehyde based dye fixing agents, hydro carbon based softeners and non-bio degradable dyeing chemicals. The Industrial effluent is also often of a high temperature and pH, both of which are extremely damaging.

After effect of effluent discharge in environment:-

  • The colloidal matter present in the Industrial Waste Water along with colors and oily scum increases the turbidity and gives the water a bad appearance and foul smell.
  • Highly Polluted and contaminated Industrial Waste water prevents the penetration of sunlight necessary for the process of photosynthesis
  • Industrial Waste Water interferes with the Oxygen transfer mechanism at air water interface. Depletion of dissolved Oxygen in water is the most serious effect of Industrial Waste as dissolved oxygen is very essential for marine life.
  • In addition when this effluent is allowed to flow in the fields it clogs the pores of the soil resulting in loss of soil productivity. The texture of soil gets hardened and penetration of roots is prevented. .
  • If allowed to flow in drains and rivers it effects the quality of drinking water in hand pumps making it unfit for human consumption.
