Kursuse eesmärk on anda teadmisi veereostusallikate, reostusainete toime ja reostuse vähendamise looduslike ja tehnoloogiliste meetodite kohta. Aines omandatakse teadmised reovee, selle omaduste, käitlemise ja puhastusmeetodite kohta, samuti reoveemuda ja sajuvee käitlemise ning kasutamise kohta.

The aim of the course is to enable the students to develop knowledge about water pollution sources, the effects of pollutants and natural and technological methods of pollution reduction. The subject acquires knowledge about wastewater, its properties, treatment and purification methods, as well as the treatment and use of sewage sludge and rainwater.

Kursuse eduka läbimise järel üliõpilane:
- tunneb veereostuse põhjuseid, toimet ja leevendamise meetodeid;
- omandab reoveekäitlemise põhitõed ja tunneb peamisi meetodeid;
- tunneb reoveesette käitlemise põhimõtteid ja oskab kasutada reoveesetet;
- tunneb looduslähedase reoveepuhastuse eeliseid ja puudusi.

After completion of the course, the student:
- knows the reasons, consequences and mitigation methods of pollution of waterbodies;
- knows the principles of wastewater treatment and the most usable methods;
- knows the principles of sewage sludge management;
- knows the principles of natural treatment of wastewater.

Kursusel käsitletavad teemad:
Veereostusallikad, reoained ja nende toime veekogule, eutrofeerumine ja veekogu isepuhastusvõime. Reovee koostis ja hulk. Reostuskoormus. Reovee kogumine ja ärajuhtimine. Eelpuhastusseadmed. Reovee mehhaaniline puhastus. Bioloogilise puhastuse alused, seadmed. Reovee õhustamine. Keemiline puhastus. Reovee järelpuhastus. Väikepuhastid. Reoveemuda ja selle omadused. Muda käitlemise põhimeetodid ja seadmed. Muda utiliseerimine. Sajuvee puhastamine. Heitvee juhtimine veekogusse ja pinnasesse. Looduslähedased puhastusmeetodid.
