INTECNA DP 4 ELECTRO ELECTROCOAGULATION COMPACT PLANT
INTECNA BASIC PRINCIPLES In electro-coagulation plant, process is realized by an electrolytic cell where anodes and cathodes are connected with a DC generator. At the ANODE reaction is Al (metal) ==== Al 3+ + 3 e- At the CATHODE reaction is 2 H2O + 2 e- ===== H2 + 2 OH- In aqueous environment, Al3+ + 3 H2O ==== Al(OH)3 + 3H+ Total Reaction is 2Al(metal) + 6H2O + 2 OH- ==== 2 Al(OH)4- + 3 H2 (gas)
INTECNA Aluminium Hydroxyls create a flocculation and on the flocks surface, all suspended material (Oil, fats, dyes, paints...) are quickly absorbed. Hydrogen developing improves the floatation of suspended materials. In the second part of flocculation tank, floating material is aggregated by special aqueous Polymer dispersion ( series HYCRAM ELECTRO) and flocks passes to filtration.
INTECNA TYPICAL GENERATOR CHARACTERISTICS FEEDING Power 400 VA three phases Frequency 50 – 60 Hz Power absorbed 8,6 KWA GENERATED DIRECT CURRENT (DC) Current 300 A Potential 24 V Power (theory) 8,6 KWA Regulation 0-100 %
INTECNA TYPICAL ELECTRODES ASSEMBLY
INTECNA Retention time in electrolytic cell is regulated by calibrating starting process by our Technical Service. Substantially, retention time is connected with Aluminium Hydroxyls formation. Such parameter is regulated by Faraday’s Law m = 1/95600 * A / V * I *t Where m = mass in grams of Aluminium dissolved A = Atomic Mass of Aluminium ( 27) V = Valence of Aluminium ( 3) I = Current (Amperes) t = time in second By our proprietary software we can evaluate the connections between : Flow-rate of wastewater Retention time in electrolytic cell Aluminium dissolved Equivalent to Aluminium Hydroxyls compounds
