Project Type: Design, supply, and installation of two Reverse Jets
Welcome to our thrilling journey where innovation meets environmental responsibility. Today, we’re diving into the heart of a groundbreaking project designed to cleanse our air, tackling the notorious sulphur dioxide (SO2) and leaving behind nothing but a breath of fresh, clean air.
The Gas Scrubber Ballet: Picture this – inlet gas gracefully pirouetting into our specialised scrubber, a dynamic choreography that sets the stage for a mesmerising performance. Travelling down the vertical inlet barrel, it encounters not one but two Reverse Jet stages in a seamless series. The gas meets its partner in crime, the scrubbing liquid, injected upward with flair. The result? A standing wave of pure turbulence is known as the Froth Zone, where the magic unfolds. performance.

The Froth Zone Symphony: As the gas and liquid waltz through the Froth Zone, a symphony of highly turbulent flow ensues. This is no ordinary dance; it’s a process where the gas is quenched to the adiabatic saturation temperature. Here, amidst the swirling waves, sulphur dioxide is captured and whisked away from the gas phase into the liquid embrace, ready for the next act.
Meet the Scrubbing Reagent Maestros: Enter our scrubbing reagents, the unsung heroes of our story. Witness the meticulous dosing of reagent slurries into the Pilot Plant sump from the Reagent Tank, orchestrated by the Reagent Dosing Pump. The dry reagent material, manually fed into the Reagent Tank, takes centre stage, twirling with a mechanical agitator and a make-up water line. The result? A perfectly prepared reagent slurry, poised for its moment in the limelight within our system.
Pilot Plant Drama: The gas and liquid duo, having waltzed through the Reverse Jet stages, take their bow in the Pilot Plant disengagement vessel. Here, the liquid slurry is collected and gracefully stored in the Sump before making its grand entrance into the Oxidization Tank. This is where the real drama unfolds: a tantalising mix of mechanical agitation and aeration sparge oxidises the slurry, ensuring the desired residence time for the ultimate transformation.

Effluent Ballet: Our production includes an eco-conscious ballet where a small portion of scrubbing liquid gracefully exits as effluent, masterfully controlling the concentration of the scrubbing liquid slurry. And for those who demand an encore, an Effluent Tank awaits.
Grand Finale: Gas Liberation! The scrubbed and de-entrained gas takes its final bow, ascending through the outlet barrel with finesse. A mist elimination section ensures the parting is clean and elegant. The grand finale? Two centrifugal blowers, operating in series, propel the gas to the terminal point or stack, releasing it into the world with the grace and poise it deserves.
Our air-cleaning odyssey, blending technology with environmental harmony, showcases a commitment to a cleaner, healthier world. Join us in this dance towards sustainability, where every step brings us closer to breathing in the beauty of a pollution-free future.
A clear PFAS extraction pathway helps utilities and biosolids operators move from monitoring and pilot testing to scalable, compliant infrastructure for long-term PFAS management.
What does pilot-scale PFAS extraction really prove? This article explores how pilot-scale validation bridges the gap between laboratory research and scalable infrastructure solutions for PFAS removal from biosolids and wastewater streams.
