A better future for wastewater · Mexico
Better biology.
Better economics.
Make the infrastructure you already have
work better.
Puro Agua brings The Ydro Process® to wastewater treatment in Mexico — targeting less sludge, lower energy use and better plant performance.
Biological treatment. Practical implementation.Built around your existing plant.
The opportunity
Change the biology.
Change the economics.
Treating water shouldn’t mean accepting ever-higher operating costs.
Sludge handling and aeration put daily pressure on plant budgets. The Ydro Process® enhances the biological treatment already taking place, helping operators address these costs without material plant reconstruction.

The business case
The saving matters
after the treatment
is paid for.
We build the business case using your sludge disposal costs, electricity consumption and proposed Ydro requirement.

View model assumptions
Illustration from the September 2026 deck. Sludge and electricity cost assumptions are extrapolated from operating data supplied for PTAR Aurea to a representative 75 L/s plant. The model assumes 70% sludge reduction and 20% electricity reduction.
$243,750 gross operational savings − $111,000 Ydro spend = $132,750 net annual savings. This is an illustrative model, not a measured plant result or a quotation. Other operating costs are outside the comparison.

A few practical questions
Start with
the right information.
Does the plant need to be rebuilt?
The Ydro Process® is introduced into the existing biological treatment process. Material reconstruction is generally not the starting point. Dosing arrangements, equipment needs and any operating changes are determined during the plant assessment.
What information do you need to assess a plant?
We begin with flow, process configuration, recent influent and effluent results, sludge production and disposal costs, electricity use and a plant schematic. An initial conversation identifies any gaps before an application is designed.
How are outcomes measured?
We agree a baseline and success criteria before implementation. Depending on your objectives, monitoring can include sludge volume, electricity, effluent parameters and odour. Consistent sampling and operating records help distinguish treatment effects from normal plant variation.
Are the savings guaranteed?
No single savings figure applies to every plant. Flow, organic loading, process conditions and local costs all matter. The figures shown here are targets or labelled illustrations; your technical assessment and trial establish the relevant case.
