  • Method for treatment of effluents using pulsed electric fields and solid/liquid separation
    Patent number: 7854851
    Abstract: This invention discloses the treatment of effluents in which a flow of the said effluents is subjected to a pulsed electric field that modifies physicochemical and biologic characteristics of the medium, this modification being used during a solid/liquid separation operation, of the settlement or membrane filtration type. The solid/liquid separation operation (13, 14, 15) and the application of a pulsed electric field (12) are operations carried out at different locations along the effluent flow. The pulsed electric field has voltage value, current value, pulse repetition frequency and voltage front shape characteristics chosen such that the required effluent treatment can be achieved as a function of the locations at which these membrane filtration operations are carried out and a pulsed electric field is applied.

  • Process for the treatment and purification of water by the flocculation of suspended particles in a fluidized bed
    Patent number: 4954259
    Abstract: The invention involves a process for the flocculation of matter suspended in water. According to the invention, the water is passed through a granular medium in a fluidized bed, without prior saturation of the granular medium in a fixed bed, and flocculated aggregates are collected downstream and subjected to settling or some other liquid/solid separation procedure, in order to obtain an effluent which is partially freed of its pollution.
