Title: Device for performing field asymmetric waveform ion mobility spectrometry
Inventor: ROGER GILES
IPC: H01J49/42
Filed: 2019-08-30
Abstract: A FAIMS device has segmented planar electrodes 820. Voltage waveforms are applied such that the asymmetric time dependent electric field has (near) straight electric field contour lines within the analytical gap, when viewed in a plane perpendicular to the analytical axis. This corresponds to establishing a linear gradient electric field across the gap. The straight/ linear contours may be achieved by using the segmented electrodes to emulate (Figs. 10C-D) the field due to truncated concentric cylindrical electrodes (Fig. 10B). This electric field focuses ions along the contour lines. Each ion species having a distinct differential mobility is focused on a distinct electric field contour line. The gradient may be adjusted to control the amount of focus. The length of the straight contours may be at least a quarter of the gap width. May have a transparent mode, exit slit and may be coupled to a mass spectrometer.

Title: High efficiency water treatment process
Inventor: ALEX DRAK
IPC: C02F103/10
Filed: 2019-11-14
Abstract: A process for treating water comprises delivering feed water to an input chamber (2, Fig. 1), passing pressurised feed water from the chamber through a semi-permeable membrane (8, Fig. 1) to produce product water and brine and removing sparingly soluble salts in the brine by passing it through a salt removal unit (20, Fig. 1), e.g. a fluidised bed crystalliser containing seed particles. The brine is subject to a series of re-circulation steps comprising: (i) returning the brine to the input chamber in a recirculation step to pass the brine through the semi-permeable membrane for re-concentration of the brine; and (ii) carrying out a series of step-by-step recirculation steps for continued re-concentration of the brine and crystallisation of low soluble salts from the recirculated brine for the purpose of increasing the recovery by membrane separation. The saturation indexes of low soluble salts during these steps are maintained within a controlled crystallisation zone: calcium carbonate logarithm of saturation index (Log SI) of 0.5 - 2.0; calcium sulfate saturation index of 100% - 400%; silica saturation index of 100% - 220%; and a barium sulfate saturation index of 100% - 5000%. The process may also include anti-scalant and/or deactivation steps.
