The present invention relates to a method of preparing N-acyl amino acids selected from N-acyl cysteine compounds, N-acyl serine compounds, N-acyl aspartic acid compounds and N-acyl glutamic acid compounds. The present invention also relates to the use of N-acyl cysteine, N-acyl serine, N-acyl aspartic acid and N-acyl glutamic acid surfactants, in removing per- and poly-fluoroalkyl substances (PFASs) from mixtures containing PFASs, such as soil and groundwater contaminated with PFASs and for use in cleaning compositions, detergent compositions and toothpaste compositions.

Method of acylating amino acids and uses of N-acyl amino acid products

The invention provides a method for removing a dissolved heavy metal from an aqueous solution. The method comprises dissolving in the aqueous solution a foaming agent of formula (I) or a salt thereof. The method further comprises passing a gas through the aqueous solution to form a foam and separating the foam from the aqueous solution. 

Method for removing heavy metals from an aqueous solution

This disclosure relates to a method, system and apparatus for inactivating microorganisms in an aqueous solution. The method comprises passing bubbles of a gas through the aqueous solution, wherein the gas comprises at least 10% CO2 by volume and has a temperature of at least 18&#xb0; C. The system comprises a gas supply to supply gas comprising at least 10% CO2 and having a temperature above 18&#xb0; C., a gas-delivery apparatus to receive the gas and deliver it into the aqueous solution in the form of bubbles. The apparatus comprises a gas-permeable material having a flow surface configured to enable the flow of the aqueous solution across the flow surface, a chamber arranged at an opposite side of the gas-permeable material to supply a gas that inactivates microorganisms such that the gas is able to pass through the gas-permeable material and into the aqueous solution as gas bubbles.

Sterilization method

This disclosure relates to a system for reducing cavitation at a surface that moves relatively with respect to a first fluid. The system comprises a degasser configured to at least partially degas a second fluid. The system also comprises a reservoir in communication with the degasser and configured to house the at least partially degassed second fluid, the reservoir having an outlet that is arranged for directing the second fluid towards the surface. The system is configured such that the directing of the at least partially degassed second fluid towards the surface forms a boundary layer at the surface. The boundary layer is adapted to at least partially increase the negative pressure required to initiate cavitation at the surface so as to reduce the occurrence of cavitation during such relative movement.

Prevention of cavitation

Disclosed herein is a method for assisting a thermally-induced change to a nano-sized solute or dispersed-phase in a liquid. The method comprises the step of passing gas bubbles through the liquid, the gas in the gas bubbles having a temperature higher than the bulk temperature of the liquid.

Method for assisting thermally-induced changes

Methods for the formation of colloidal suspensions. The method includes combining an aqueous substance with a second substance that is normally immiscible with the aqueous substance, to form a mixture, and before, during or after the combining removing dissolved gases from one or both of the aqueous and second substance, whereby the aqueous and second substances mix and form a colloidal suspension. The methods for the formation of colloidal suspensions include methods for the formation of emulsions as well as particulate dispersions. The methods used to form the colloidal suspensions in accordance with the present invention produce colloidal suspensions that are stable for periods from an hour to several weeks in the absence of surfactants or stabilizing agents.

Process for the production of emulsions and dispersions

The invention provides a method for the removal of biological species, such as, from water using aluminium based media which contains surface Al&#x2014;OH groups.

Method of water purification

Apparatus and methods for determining the minimum film formation temperature of a latex are disclosed based upon the measurement of the conductivity of the latex as the temperature of the latex is varied. By plotting the latex's conductivity and temperature relationship, the minimum film formation temperature is determined.
