  • Method for treating an aqueous liquid by means of a filter determined as a function of the interfacial tension of the liquid
    Patent number: 10745298
    Abstract: The present invention relates to a method for treating an aqueous liquid comprising oil droplets and a surfactant and/or a base. For this method, a pore size threshold of a filter is determined taking into account the interfacial tension between the oil droplets and the water, and a filter is selected whose pore size is less than or equal to this threshold for filtration of the aqueous liquid.
    Type: Grant

  • Process for treating an acidic waste water stream
    Patent number: 4035293
    Abstract: Disclosed is a process for purifying an effluent containing acids such as phosphonic and phosphoric acids by the addition of CaO or Ca(OH).sub.2 in an amount ranging from 55-93 per cent by weight basis acids at a temperature of 35.degree. to 100.degree. C to a pH of 8 to 12. After removing the precipitated material, the effluent can be neutralized with CO.sub.2 gas. The precipitate can be calcined to tri calcium phosphate.
