  1. 1. POLAND KRAKÓW
  2. 2. Republic of POLAND• Location: Central Europe• Capital city: Warsaw• Member of European Union since 2004• Area: 312,685 km2 (water: 3.07%)• Population: ~38 mln• Terrain: mostly flat, mountains on the south• Coastline with Baltic sea: ~491km
  3. 3. Kraków• Second biggest city in Poland (after Warsaw)• Lies in the southern part of Poland, on the Vistula River (Wisła) 219 m above sea level• City area: 327 km2• Population (31 December 2011): ~756 000 (~1,400,000 in metropolitan area)• Density: ~2,300 / km2
  4. 4. GABRIELA | KAROLINA | WERONIKA | MACIEK VIII PALO
  5. 5. Water sources• Possible water production per day – 297.4 thousand m 3• Total length of water supply network – 2056 km• Estimated number of citizens exploiting from the water supply network - 99.5%
  6. 6. Water Treatment Plants (WTP) in Kraków• The “Bielany” WTP - Zbiornik Dobczycki• The “Rudawa” WTP - Rudawa river – Podkamyk reservoir• The “Dłubnia” WTP – Dłubnia river and Mistrzejowice deep wells• The “Raba” WTP – Sanka river
  7. 7. Water distribution
  8. 8. Water production 2007-2011
  9. 9. Process of water purification
  10. 10. Process of water purification• The process of purification and of becoming drinking water for our school takes place in ZUW (place of water conditioning) Raba. It consists in mixing water with ozone, coagulation, sedimentation, filtration and disinfection.• Mixing water with ozone is one of the ways of disinfection of water. It provides microbiological purity of water.• Coagulation consists in joining of colloidal molecules present in water into larger aggregates that falls down rapidly. As a result a precipitate is created and above it there is a clear water.
  11. 11. Process of water purification• Colloids – natural elements of water coming of mineral or organic origin which cause the opacity and influence the colour of water.• Sedimentation – the process of self-acting subsiding of particles present if water if their density is greater than the density of water.• During the filtration water is put through a filter that puts a physical barriers of undesirable particles• Disinfection consists in deactivation and destruction of killing and pathogenic particles. It results in termination of their growth and reproduction.

  25. 25. Is water from our taps drinkable?• YES!• but... there is still a common conviction that it should not be drunk without boiling, otherwise it may be dangerous• Even though bottled water market is doing well - in general there is a broad variety of tastes (depending on water source)
  26. 26. Industrial water treatment• In Kraków there are six waste water treatment institutions.• Two main : „Płaszów” and „Kujawy” and four small local ones : „Bielany” , „Łęg” , „Kliny” and „Dąbie”.• „Płaszów” is the biggest and the oldest, it is one of the first water treatment institutions in Poland.• „Kujawy” is right after „Płaszów”, before year 2003 it used to be the most modern institution in whole region of Poland, now „Płaszów” institution extension has been finished
  27. 27. „Płaszów”
  28. 28. „Płaszów”• It used to purify water mechanically, but now after modernization from 2003-2007,is more environmental friendly and purified in biological ways• It supports needs of over 780 thousands of Kraków inhabitants.• Average daily flow of sewage is about 165 000m3
  29. 29. „Kujawy”•From the beginning which is 1999 purifies water in biological ways•Average daily flow is about 52 000 m3

  33. 33. A few facts about sewage system inour city• It consists of two independent parts which end in different industrial water treatment institutions• It is about 1680 km long and still growing• Soon with growth of agglomeration of Kraków we will reach sewage capacity limits.
