Abstract

A METHOD AND APPARATUS FOR INHIBITING SCALING IN AN ELECTRODEIONIZATION SYSTEM (10) OR IN A COMBINED REVERSE OSMOSIS/ELECTRODEIONIZATION SYSTEM (62, 10FOR WATER TREATMENT AND, MORE PARTICULARLY, FOR INCREASING TOLERANDE TO HARDNESS IN THE FEED WATER AND FOR INCREASING EFFICIENCY OF THE ELECTRODEIONIZATION UNIT (10) IN WHICH A CONCENTRATE STREAM RECYCLING (12) THROUGH CONCENTRATING COMPARTMENT (18) AND ANODE AND CATHODE COMPARTMENTS (20, 22) CONTAINING EFFECTIVE AMOUNTS OF AN ANTISCALANT TO INHIBIT PRECIPITATION OF SCALE. ONE OR MORE PRELIMINARY REVERSE OSMOSIS UNIT (62,72, 74, 90, 100, 110, 120, 130, 140,) IN SERIES WITH THE ELECTRODEIONIZATION UNIT (10) PREFERABLY RECEIVES APORTION OF THE ANTISCALANT IN THE CONCENTRATE STREAM (12,44). THE ANTISCALANT IN THE WATER FED TO THE REVERSE OSMOSIS UNIT (62) CAN BE SUPPLEMENTED AND ADJUSTED. ELECTROLYTE CAN BE PROVIDED TO THE CONCENTRATE STREAM (44) OF THE ELECTRODEIONIZATION UNIT FROM PRODUCTS OF THE REVERSE OSMOSIS.(FIG 1)
