| Stages | Pre-treatment, RO, disinfection |
| Pre-treatment | Multi-media filter, carbon filter, softener |
| RO | Reverse osmosis with a storage and buffer tank |
| Disinfection | UV, ozone, or both |
| Key control | Raw water analysis, recovery rate, conductivity |
| Key decision | Which stages the raw water actually needs |
The raw water analysis decides it. Surface water usually needs multi-media filtration, carbon and RO; hard well water needs softening before the RO; low-hardness municipal water may only need carbon and disinfection. A package bought without an analysis is either oversized or short of a stage.
One month ago, we received a 2 ton per hour single loop automatic CIP station order from Saudi Arabia.
RO produces permeate and rejects concentrate. The recovery rate sets how much of the feed becomes product water, and the buffer tank size sets how long the line can run when the RO is in flush or maintenance. A filler that outruns the RO starves at shift start, which looks like a filler problem and is not.
| Stage | Removes | Driven by |
|---|---|---|
| Multi-media filter | Suspended solids | Turbidity of raw water |
| Carbon filter | Chlorine and organics | Municipal dosing and taste |
| Softener | Hardness | Calcium and magnesium in the analysis |
| RO | Dissolved salts | Conductivity target of the product |
| UV or ozone | Micro-organisms | Storage time and final barrier |
Throughput and change-part lists are on the Water Treatment page rather than in this note.
UV leaves no residue and acts instantly, but it has no residual effect in the bottle. Ozone leaves a residual that protects the water in storage, and it needs a destruction step before filling. Many plants run both: ozone for storage, UV as a final barrier.
Rated output, change parts and services are listed on the Pre-treatment page.
Flow, temperature, concentration and time, all four together. A CIP that meets the temperature but not the flow does not clean the far end of the circuit, and the failure appears as a micro result weeks later. The station is sized on the largest circuit it serves.
The same question is worked through from another angle in How to Select a Water Treatment System for Your.
On condition, not on a calendar. Track permeate conductivity, pressure drop and recovery; replacement follows a trend, and a sudden change usually means a pre-treatment failure rather than membrane age.
Pre-treatment removes suspended solids, chlorine and hardness that would foul or damage the membrane. RO removes dissolved salts. RO without correct pre-treatment fails early and expensively.
It can be used only after analysis. Borehole water often carries hardness, iron or manganese, all of which need a stage before the RO or before filling.
It is a controlled circuit that circulates cleaning solution at a set flow, temperature, concentration and time. Any line filling a product other than water needs one, and its capacity follows the largest circuit.
