Jan. 18, 2011 - PRLog -- In the  industrialised  countries  the  first  water  treat- ment  techniques  involved  processes  of  a  purely physical  and  mechanical  nature  to reduce the solid content.  The  limitations  of  both  the  results  and  the applicability  of  these  processes  later  led  to  the  use  of treatments  of  a  chemical  nature.  At  the  beginning  of the  20th  century  water  hygiene  problems  were  over- come  by  adding  chlorine.  At  the  same  time  other types  of  treatment  were  introduced,  with  specific objectives,  such  as  rendering the water  softer  or  re- ducing the iron content.

The  various  Wastewater Treatment Plant  processes  have  the following  objectives:

to  confer  and  preserve  the  inherent  physical chemical  and  biological  qualities  of water of dif- ferent  origins  which  make it suitable  for  specific uses  such as  water  for  drinking and  for  use  in productive  processes; to permit  astewater  treatment  which will pro- tect the public  from  health  risks  without  causing any  damage to the environment; to  confer  and  preserve  those  characteristics  of water in its natural  environment  which  are  nec- essary for the conservation  and  development  of ichthyo  fauna  and  aquatic  vegetation,  and  for provision  of  drinking  water  for  cattle  and  wild
animals  or  for  recreational  and  aesthetic  purposes.

Waters that are used for drinking, manufacturing, farming, and other purposes by residences (toilets, baths, showers, kitchens, sinks), institutions, hospitals, commercial and industrial establishments are degraded in quality as a result of the introduction of contaminating constituents. Organic wastes, suspended solids, bacteria, nitrates, and phosphates are pollutants that commonly must be removed.
