For design engineers / specification support

Specify from evidence. Scope the engineering.

Bring treatment objectives, representative water data and design constraints together. Critical Elixirs can help assess chemistry and equipment options, with a clear route to in-house RPEQ support where the project scope calls for it.

Field conditions vary / scope each deployment

Testing / specification / engineering

Make the assumptions visible before the specification hardens.

Water-treatment selection depends on the actual matrix, treatment objective, operating conditions and project constraints. A useful specification begins by documenting what is known, what needs testing and who owns each design decision.

  1. 01

    Define the duty

    Share water-quality data, target conditions, basin arrangement, flow expectations and the requirements that govern the project.

  2. 02

    Build an evidence base

    Representative testing can compare chemistry, dose response, pH behaviour and settling to support option selection and design assumptions.

  3. 03

    Match the equipment

    Review trailer or IBC-mounted dosing stations, chemical storage, pumping, mixing, power and site access as one arrangement.

  4. 04

    Agree engineering scope

    Bring the design team in early to confirm deliverables, design inputs, review boundaries and any certification requirement before work begins.

Option development

Compare the chemistry and the delivery system.

Jar testing can inform candidate chemistry, starting dose, pH response and settling behaviour. Pair those observations with a practical dosing arrangement: pump duty, chemical format, mixing, controls, storage, access and maintenance.

  • Chemistry

    Standard market and bespoke options can be assessed against the water and treatment objective.

  • Dosing equipment

    Trailer-mounted or IBC-mounted stations can be reviewed against layout, utilities and operating responsibilities.

  • Test evidence

    Record representative sample conditions and treat bench results as guidance for field verification, not a performance guarantee.

Engineering route

Need RPEQ input? Define the certification scope first.

In-house RPEQ support is available for suitable, agreed engineering work, including review, optimisation and certification-related support. Before engagement, align on design basis, supplied information, deliverables, review boundaries, interfaces and exactly what certification is being requested.

A clear scope protects the design decision

Engineering support does not imply that a design has been certified, that project approvals are satisfied, or that a site outcome is guaranteed. These depend on the agreed scope, complete inputs, applicable requirements and site implementation.

Coordinate the next step

Support is available for suitable projects across Australia, subject to scope, timing and mobilisation logistics. Share location, project stage, water data and any certification expectations.
