Influence of Water Treatment Technology on the Stability of Tap Water

Control of water quality changes in the distribution system is an important issue, due to consumer health, and a threat technical infrastructure. Annual monitoring allowed us analyze physical, chemical, biological stability produced two different technological systems. The article examines extent which purification technology affects possibility uncontrolled during its transport (the risk secondary pollution has been estimated). Based on obtained results, it was found that groundwater treatment based following processes—aeration, coagulation, sedimentation, filtration, disinfection—does not ensure effective elimination biogenic substances determine sanitary safety. extended by additional biofiltration process granulated activated carbons (GAC) contributed improvement treated (lowering content nutrients) reduced losing system. did change physical chemical water; calculated corrosiveness indicators showed waters are devoid aggressive properties, with tendency precipitate CaCO3. production stable step forward controlling from source tap.
