Abstract

Argichi  river  is  the  deepest  river  running  into  the  lake  Sevan.  The  river  waters  irrigate areas under crops of more of villages of Gegarkunik region in Armenia. The river Argichi is a habitat for reproduction brought in the Red book of fauna of Armenia for fishes. Hence, for the purpose of maintenance  of  safety  of  fauna  of  the  rivers,  it  is  necessary  to  treated  river  water.  This  research includes a situation of sewage in river Argichi, type and quantity of polluted materials and products,
the  attempts  to  present  of  the  sewage  treatment  systems.  and  the  development  of  technology  for sorbent with polysorption properties with application of natural materials widespread on territories of Armenia. The  results  of  purposeful  researches  are  submitted  in  the  field  solutions  and  waste  water  of application natural zeolites as sorbents  for removal of organic substances from water. High level of adsorption of organic substances natural zeolites is provided with their initial saturation by ions of calcium and magnesia. It has been found advantageous to organic compounds sorption by natural   zeolites.   The   advantages  of   natural   zeolite   in  comparison   with   other   sorbents   are technological stability, low cost, availability, filtering properties. Thus, the sequence of operations in sorption will be the following: the first is  sorption of metals and ammonia, the second is sorption of organic substances.
