Proof, not promises
Anonymised cases with client-confirmed figures — effluent taken to zero discharge, municipal water displaced by on-site treatment, corrosion stopped at its cost. No invented numbers, ever.
Three different plants, three different waters: acid effluent at a steel coating line, borehole water at a food factory, a small cooling circuit at a plastics moulder. They are on one page because they answer the same question a plant manager asks before trusting a water treatment supplier: what changed on a site like mine, and how do you know?
Each write-up follows the same order — the problem as the plant felt it, the programme, and the result in figures the client has confirmed. The clients are not named; the numbers are theirs.
Three write-ups
Each one opens with the situation it fits, so you can go straight to the case that reads like your own site.
Effluent & heavy metals removal
Read this if a metals limit decides whether your effluent can be discharged or reused.
Overall heavy metal reduction above 99.9%
The chemistry was verified at laboratory scale before full-scale work, then sampled daily on site against the old lime-only treatment. The proof came from the plant, not from a data sheet.

Read this if the municipal water bill is a growing line on your cost sheet.
Around 1,140 kl treated against 239 kl of municipal top-up in a reference month
A borehole feed and a reverse osmosis system turned municipal supply into a backup. The case is five years of running, not a commissioning-day snapshot.

Read this if a small circuit is running up a large maintenance bill.
Moulds going out for polishing at around R3,000 each — corrosion resolved
A circuit of roughly 2 m³/h was damaging production moulds. The size of a system says little about the size of its cost; the programme was designed for the circuit and the mould metallurgy.
Read the case study| Case | Problem | Programme | Result |
|---|---|---|---|
| Steel pipe coating plant | Acid pickling effluent with dissolved iron, zinc and lead; lime-only treatment left iron high | EPSE chemistry verified at laboratory scale, then full-scale with pH control automated to a 9.5 target | Overall heavy metal reduction above 99.9%; fully recycled water, zero discharge |
| Food producer, Cosmo City | Rising municipal water consumption costs | A 4.5 m³/h reverse osmosis system on borehole feed, commissioned October 2020 | Around 1,140 kl treated against 239 kl of municipal top-up in a reference month; operational for over five years |
| Plastics moulding plant, Pretoria | Corrosion through a roughly 2 m³/h cooling circuit damaging production moulds | A cooling water chemistry programme designed for the circuit and the mould metallurgy | System fully operational; corrosion problem resolved |
The common thread
Different sectors, different chemistry — the same way of working.
01
A full plant clean every three months. A municipal water bill that kept rising. Moulds sent out for polishing. None of these began as a chemistry question — they began as money leaving the site.
02
Laboratory verification before a full-scale effluent change. A reverse osmosis system engineered for a borehole feed. Cooling chemistry matched to the metal in the moulds. No programme was taken off a shelf.
03
Milligrams of iron per litre. Kilolitres of municipal top-up. Months between cleans. These are numbers the client measures, and they are the numbers the programmes are judged on.
What to take from them
If you can state your water problem as a cost, a fix can be measured against it. Before a site assessment, gather what you already have: water bills, discharge limits or licence conditions, lab results, and the maintenance records that show what the water is costing you. That is the baseline every result on this page was measured from.
The method behind all three is set out on how we work. Two further projects, a rainwater harvesting scheme and an effluent reuse scheme, are summarised with the company record on the about page. If you are weighing up suppliers, our guide to choosing a water treatment company sets out the proof worth asking for.
Book a site assessment. We survey your systems, sample your water, and state exactly what we would do — then prove it with your own plant's data.
