ECOLOGICAL ASPECTS OF SLUDGE DISPOSAL IN SLOVAKIA

Abstract

There are monitored “ Great Boom” by building of new sewage systems in Slovakia in last years, especially in areas, where was low connection to the public sewage systems. There is coming
great amount of finances for building a new sewage system in Slovakia. But at first we have to find the general  idea  how  to  build  this  system  with  the  view  of  technical  and economical  relations. Quantitative  production  of  sludge  from  urban  waste  water  treatment  as  well  as  the  issue  of  their contamination  has  been  continuously  monitored  in  Slovakia  since  1998.  Basic  principles,  together with  the  monitoring, have been  derived  from  the  concepts  of  management  of  sludge from  municipal wastewater  treatment  plants.  Controlled  land  application  of  sludge  was  stipulated  as  the  principal method of handling sludge. This process has not only been selected for being relatively the cheapest way  for  the final  disposal  of  sludge,  but  is  assumed  to  be  the most acceptable  option  in the  Slovak conditions, as well.
