Removal of phosphorus compounds from water experience from technological research
The aim of the technological research was to determine the technology which would enable reduction of the concentration of phosphorus compounds in water to the level of 0.02 mg PTot/dm3. The raw water during the study period was characterized by a pH of 6.66 to 7.62 and a variable concentration of p...

| Summary: | The aim of the technological research was to determine the technology which would enable reduction of the concentration of phosphorus compounds in water to the level of 0.02 mg PTot/dm3. The raw water during the study period was characterized by a pH of 6.66 to 7.62 and a variable concentration of phosphorus compounds ranging from 0.150 to 0.366 mg PTot/dm3, including phosphates in the range of 0.039 to 0.089 mg PO4/dm3. The concentration of chlorides was below 10 mg Cl/dm3 and sulphates did not exceed 14 mg SO4/dm3. Treated water was intended for soil application therefore its quality after treatment could not exceed the limit values set forth in the regulations in force during the study period. The conducted research has shown that the use of the coagulation process based on the ferric coagulant PIX 112 combined with rapid filtration ensures the required quality of the treated water, among other things, through lowering the concentration of PTot to 0.02 mg/dm3. |
