Abstract
The invention concerns a method of treating liquids by means of oligodynamy, particularly of sullage waters. The waters are passed between metal electrodes supplied with electric current before being allowed to settle. The waters which have been subjected to the oligodynamic treatment are then submitted to at least one positive degassing operation and/or a part at least of the flocculate being formed is recovered and said flocculate is re-introduced into the water which has just flowed between the metallic electrodes. The flocculate resulting from the treated waters is then separated.
Claims16
A method for purifying liquids by means of oligodynamy, consisting essentially of:
- regularly passing the totality of the liquids between electrically supplied metal electrodes, whereby the liquids are treated and metal ions are homogeneously dissipated in the treated liquids to provide formation of flocculates;
- subjecting the treated liquid to a physical treatment which causes a substantial quantity of gas bubbles to separate from the flocculates just being formed in the liquid;
- removing the separated air bubbles;
- and
- separating the flocculate and evacuating purified liquids.
