Waste water cleaning assembly, at washing machine outflow, has tubular vessel with electrodes to generate a pulsed high voltage field for acceptable release of grease/oil and organic/inorganic matter into drains

摘要

Assembly to clean the waste water from washing machines, has a vessel with a tubular wall (5) to take the waste water which is fitted with two insulated electrodes (2,4) to generate a voltage field, with at least one electrode within the vessel. A high voltage unit (3) generates a pulsed direct voltage of =1 kV and preferably =20 kV and especially =70 kV in a pulse frequency of 500 Hz to 200 kHz. Assembly to clean the waste water from washing machines, has a vessel with a tubular wall (5) to take the waste water which is fitted with two insulated electrodes (2,4) to generate a voltage field, with at least one electrode within the vessel. A high voltage unit (3) generates a pulsed direct voltage of =1 kV and preferably =20 kV and especially =70 kV in a pulse frequency of 500 Hz to 200 kHz. One electrode has a ring and/or serpentine shape and one or more counter electrodes are near the wall. The vessel is of a plastics resistant to alkali and/or acid, with an upper inflow (1) and a lower outflow (17).
