ELECTROLYSIS METHOD, AND METHOD AND PLANT FOR THE PRETREATMENT OF RAW WATER

摘要

The invention relates to an electrolysis process using iron particles and an aqueous solution containing sodium hypochlorite. This process is characterized in that it uses direct current, in that the iron particles constitute the anode (46) and in that the concentration of sodium hypochlorite in the aqueous solution is at least 1 g / l. The invention also relates to a raw water pretreatment process and installation intended to produce a water which can then be treated to give a drinking water or a so-called technical water, that is to say unsuitable consumption, but can find household, agricultural and industrial uses, such as cleaning, washing, washing, flushing, watering a garden or irrigation. The pre-treatment facility includes an electrolysis device and biological filters.
