Abstract (croatian)
Najčešći izvori fosfora u vodama uključuju industriju, poljoprivredu, stočarstvo i kućanske otpadne vode, a povećane količine fosfora u vodi izazivaju onečišćenje vode, smanjenje količine kisika i eutrofikaciju. Stoga je u ovom radu analizirana učinkovitost elektrokoagulacijskog uređaja sa željeznim elektrodama na smanjenje koncentracije fosfata u vodi. Na pilot uređaju provedeno je pet različitih eksperimenata u kojima su varirani različiti operativni parametri kao što su jakost struje, protok, vrijeme rada reaktora i dodatak elektrolita. Nakon 120 minuta rada reaktora, pri protoku od 0,05 l/s i jakosti struje od 5 A, koncentracija fosfata se smanjila sa 50 mg/l na 10 mg/l, a nakon 24 sata taloženja, na 2 mg/l. Pokazalo se da dodatak soli od 2 g/l ne utječe na učinkovitost uklanjanja, ali utječe na smanjenje potrošnje električne energije, a time i na smanjenje operativnih troškova procesa.
Abstract (english)
The most common sources of phosphorus in water include industry, agriculture, livestock and domestic wastewaters, and the increased amount of phosphorus in water can cause eutrophication, water pollution and oxygen depletion. In this paper the efficiency of the electrocoagulation using iron electrodes was analysed in order to reduce the phosphate concentration in water. Five different experiments were conducted on a pilot device and different operation parameters were varied, such as current, flow rate, operation time and the addition of supporting electrolyte. After 120 minutes, with flow rate of 0,05 l/s and current of 5 A, the phosphate concentration decreased from 50 mg/l to 10 mg/l, and after 24 hours of sedimentation to 2 mg/l. It was shown that the electrolyte addition does not affect the phosphate removal efficiency, but decreases electrical energy consumption, and thus, decreases operational costs of the process.
