| 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.
Modern lines instrument the wash with conductivity, temperature and flow sensors so every filling machine cycle is provably sanitary.
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.
This guide explains how conductivity confirms caustic/sanitizer presence, how temperature logging proves kill step, and how flow/turbulence assure full coverage — the three pillars of auditable CIP on a Combiblock.
| 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 |
Site requirements, air and power consumption sit with the Water Treatment.
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.
Validation demonstrates that each circuit reaches the required chemical concentration, temperature and contact time to deliver a specified log reduction of microbes.
The unit behind this configuration is the Pre-treatment.
The RO membrane, mainly. Hardness scales the membrane surface, which raises pressure and cuts recovery. A softener upstream is cheaper than a membrane replacement and is sized on the hardness in the water analysis.
The same question is worked through from another angle in How Water Treatment Improves Beverage Taste.
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 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.
On chlorine breakthrough and on the supplier recommendation, not on a fixed calendar. A carbon bed that is exhausted lets chlorine reach the RO membrane.
