Service packages

Start simple. Add what your site needs.

Begin with a competitive standard maintenance package, then add Purus sidestream filtration if your site needs it. Pricing is prepared after a short site assessment.

Package 1

Standard Maintenance

Scheduled visits, water sampling and on-site checks, chemical top-ups and dosing verification using Viva Blu products, visual system inspection and clear reporting. The straightforward entry point for most sites.

Package 2

Purus Plug-and-Play Sidestream Service

Optional. Blue Quest deploys a plug-and-play Purus unit that continuously draws a sidestream from your circuit, filters it and returns the treated water, and operates and maintains it for you. Backed by a trial on a manufacturing chiller circuit with biological fouling, with samples analysed by ALS Laboratories. Site assessment required.

Packages can be combined. Request details below for a site-specific quote.

Plug-and-play sidestream

What the sidestream service aims to do.

A continuous recycle-and-return approach that polishes circuit water online. Outcomes are site-dependent; the strongest supporting result comes from a closed-loop industrial chiller circuit with biological and suspended-solid fouling.

Continuous online polishing

Treats a portion of the circulating water while the system keeps running, returning cleaned water to the circuit.

Potential chemical savings

Removing suspended solids and biofilm precursors can make biocide and inhibitor programs work more effectively. Any reduction is site-specific and something we would measure with you, not promise upfront.

Potential lower water use

Cleaner circulating water may allow higher cycles of concentration and less blowdown, depending on system design and water chemistry. Dissolved solids and hardness still need to be managed by your treatment program.

Energy & capacity recovery

Reduced fouling can help restore heat-transfer performance. In the Evolve Group chiller trial, 10 m of head pressure was restored and operating costs fell; results are site-specific.

Less maintenance & downtime

Fewer manual cleans of heat exchangers, sumps and strainers may be needed. Blue Quest looks after the unit, so site labour stays low.

Longer equipment life

Less under-deposit corrosion, abrasion and scale from suspended solids may help protect chillers, piping and pumps.

Evidence note. The strongest supporting result is the Evolve Group manufacturing chiller trial, with samples analysed by ALS Laboratories: a significant reduction of bacteria and suspended solids, 10 m of head pressure restored and reduced operating cost. See the case studies. Savings are potential and site-specific, not guaranteed. Laboratory results (up to 7-log MS2 bacteriophage removal in university laboratory tests on a fresh gel layer) are not a site result and need verification on your system. Detailed reports available on request.
Indicative pricing

A rough monthly figure for the Purus sidestream service.

Three questions give you a ballpark before a site assessment. It is an indication only, not a quote, and it covers Package 2 only.

If you are not sure, leave this on Standard. We confirm it at the site assessment.
Indicative service rate (ex GST)
 
 

Includes the plug-and-play unit, scheduled servicing, consumables and a chemical allowance. Commissioning and decommissioning are one-off charges quoted per site. Final pricing follows a site assessment.

Discharge cleanups & polishing

Other water-polishing duties, assessed site by site.

There is no trial data yet for these duties. The same plug-and-play approach can be evaluated for temporary or permanent polishing of water that must meet discharge limits or be reused, but suitability, any supplementary treatment and expected performance are worked out per site.

Construction dewatering discharge

Mobile or containerised units can be assessed for polishing excavation and groundwater toward the limits in your approval or council requirements. Iron-rich or complex waters usually need supplementary steps such as pH adjustment, oxidation or settling.

Concrete washout & process water

Possible for reuse or discharge polishing, but washout water is typically highly alkaline and sediment-heavy, so neutralisation and settling usually come first. Feasibility depends on solids loading and chemistry.

Industrial blowdown polishing

Can be assessed as a suspended-solids stage ahead of other treatment, such as RO or softening, to support reuse or lower discharge. It does not remove dissolved salts or hardness.

Stormwater & site runoff

Temporary polishing of sediment-laden runoff may help during earthworks, as part of a broader sediment-control plan.

Groundwater & iron-rich water

Filtration can address suspended loads. Dissolved metals and pH need additional treatment beyond filtration.

Other polishing duties

Tank clean-outs, pre-treatment ahead of other systems or short-term needs, each confirmed against your feed quality and treatment goals.

These applications go beyond the chiller-circuit trial. A site assessment determines suitability, any complementary treatment, and whether your discharge criteria can be met.
Why these packages

Options that fit how your site runs.

Routine maintenance, with optional advanced filtration where your circuit needs it.

Reduced fouling

Sidestream filtration targets the suspended solids and biofilm precursors that foul heat exchangers.

Chemical program support

A cleaner circuit gives your dosing program a better chance of holding control. Savings are measured with you, not assumed.

Energy & maintenance

Cleaner circuits can mean less unscheduled cleaning and better heat-transfer performance.
