Australian / Field-capable / Engineering-led
Engineering and Chemistry. Together. Finally.
We help civil contractors, design engineers, water utilities and industrial operators solve site water and sewer treatment problems. We test and supply chemistry, supply and support dosing systems, and provide in-house RPEQ engineering. We support suitable projects across Australia, subject to scope and mobilisation logistics.
Why Critical Elixirs
One field-capable team from chemistry selection to measured dosing.
Chemistry that fits
Bespoke formulations and standard market options, selected through testing against your water and treatment objective.
Field-ready dosing
Trailer-mounted and IBC-mounted stations, with commissioning, calibration and recovery support.
Independent performance checks
We can calibrate and report dosing performance using your existing chemistry, whether supplied by us or another provider.
In-house RPEQ support
Engineering input for certification and optimisation of site operations and treatment performance.
Priority offer
HES Basin Solutions
Trailer and IBC dosing stations, proprietary and standard chemistry options, jar testing, calibration and RPEQ support for High Efficiency Sediment Basins on civil sites. Our own formulation, dosing and engineering, from one field-capable team.
From the field
Our dosing equipment, proprietary HES coagulant, sample testing and basin field work — photographed during real operations.
Trailer-mounted dosing station deployed in the field. 
CLEARFLOW GO™, our proprietary HES coagulant. Specifications supplied on enquiry. 
Jar test sample. Jar testing compares options on your own water. 
Basin field work: water conditions inform treatment selection.

The right chemistry is only part of the result.
Septine, Suppressor and magnesium hydroxide (pH Elixir Basic and Premium) are distinct options for sewer treatment. We also calibrate and report dosing performance independently of the chemistry selected—including products supplied by another provider.
