Hardness-free drinking water for 55,000 residents of Antonio Ante
We designed, assembled and installed the filtration and softening system of the «General Enríquez» drinking water plant. It treats 20 L/s of well water and meets NTE INEN 1108.

Well water with almost four times the hardness of very hard water
The deep wells that supply Atuntaqui delivered water with 700 mg/L of hardness as CaCO₃. The municipal government needed to remove it without interrupting service.
- Scale in the networkDeposits in pipes and distribution networks.
- Affected equipmentDeposits in water heaters, faucets and equipment in homes and businesses.
- Standard to meetWater fit for human consumption according to NTE INEN 1108.
Total water hardnessmg/L as CaCO₃
According to the USGS classification, water is very hard from 180 mg/L. The well water was almost four times that value.
- 20 L/scontinuous flow
- 50 PSIoperating pressure
- 0 mg/Lhardness in the treated water
- < 5 NTUturbidity
Treatment train: from the well to the network
Three stages and 12 fiberglass tanks treat 20 L/s of well water before delivering it to the distribution network.

1
Pumping
Draws water from the well and drives it through the whole train with stable flow and pressure.
- 3 centrifugal pumps
- 20 L/s continuous flow
- 50 PSI operating pressure
2
Sediment filtration
Retains suspended solids so the water reaches the resin clean.
- 6 fiberglass tanks
- High-purity zeolite over gravel
- Manual backwash valves
- Final turbidity below 5 NTU
3
Softening
The cation resin retains calcium and magnesium and delivers water with 0 mg/L hardness.
- 6 fiberglass tanks
- Ion exchange cation resin
- Automatic regeneration valves
- Brine suction and tank
From design to validation
A single team handled the entire project, and the treated water meets the national standard.
What Sanitron did
- Engineering and designTreatment system tailored to the well water.
- SupplyFiberglass tanks, zeolite, cation resin and valves.
- Assembly and installationComplete electromechanical installation at the plant.
- Start-up and validationTests and physicochemical control according to NTE INEN 1108.
Results
- 0 mg/L hardnessWell below the limit allowed by NTE INEN 1108.
- Scale-free networksPipes and distribution networks protected against scaling.
- Verified compliancePeriodic monitoring by the municipal government confirms the physicochemical and biological parameters.
