28-76 ÎNDEPĂRTAREA IONULUI FOSFAT DIN APELE UZATE PRIN METODE FIZICO-CHIMICE

REMOVAL OF PHOSPHATE ION FROM WASTE WATERS WITHPHISICAL AND CHEMICAL METHODS
In these paper comparative studies we made for the removal of phosphate ions from wastewaters using two different methods. First method is precipitation-coagulation using ferric sulphate or ferric chloride like coagulation reagent and the second method is electroflotocoagulation with iron disposal anode.
Keywords: phosphat ions, waste water, precipitation-coagulation, electroflotocoagulation

28-75 STUDII PRIVIND EPURAREA APELOR UZATE CU CONŢINUT DE ULEIURI VEGETALE PRIN PROCESUL DE ELECTROFLOTOCOAGULARE

STUDIES REGARDING TREATMENT OF WASTEWATER WITH VEGETAL OILS CONTENT BY ELECTROFLOTOCOAGULATION PROCESS
Wastewater treatment means the combination of measures and processes by which the impurities of chemical or microbiological nature contained in wastewater are reduced under certain limits, so these waters will not cause any harm to the receiver which is discharged and not to endanger its water use. One of the advanced methods for this removal is electroflotocoagulation. In this paper we studied the optimal condition and efficiency of electrocoagulation process in the removal of vegetal oils from waste waters. The studied conditions are intensity of electrolysis current, electrolysis time and dynamic water flow rate through electrolysis cell.
