Water Treatment Systems for
Bottled Water Plants and Food & Beverage Production.
Water treatment for bottled water plants and food and beverage production must meet one standard: every contamination event in the treatment train reaches the fill point. We engineer each system for drinking water bottling plant output targets, source water profile, and applicable food safety standard.

Which of these describes your production facility?
Three pre-engineered configurations for the most common food and beverage water applications. Find the description that matches your production type — then request the full specification from our engineering team.
Bottled water plant or beverage production
Water is the product · Consistent TDS and microbiological safety required
- Producing bottled water, soft drinks, juices, or ready-to-drink beverages where water is the product or directly contacts it
- Need consistent TDS, taste profile, and microbiological safety across every production batch
- Regulatory or customer spec drives output water quality — TDS target, bacterial count, and disinfection method
Filter suspended solids → RO to target TDS → Kill bacteria and viruses (UV + ozone) → Bottled water plant fill point
After you submit — an engineer reviews within 24–48 h. No complete water analysis required to start; send available data and we will identify what is still needed.
Food processing plant — wash water and process water
HACCP compliance · High volume · CIP and ingredient water
- Water used for washing produce, blanching, ingredient mixing, or food processing cleaning circuits — not bottled or beverages
- HACCP, ISO 22000, or local food safety authority compliance is required
- High daily volume and hardness causing scaling on heat exchangers or in-place cleaning pipework
Filter solids and residual chlorine → Soften to remove hardness → Disinfect → Supply to process and cleaning circuits
After you submit — an engineer reviews within 24–48 h. No complete water analysis required to start; send available data and we will identify what is still needed.
Brewing, dairy, or flavour-critical production
Mineral profile matters · Specific Ca, Mg, alkalinity target
- Brewing beer, producing milk, yogurt, or flavour-specific beverages where mineral balance affects product taste
- A specific water mineral profile (Ca, Mg, alkalinity, hardness) is required — not just clean water
- Colour, flavour, or fermentation consistency depends on water chemistry being reproducible batch to batch
Strip all dissolved solids (RO) → Remineralise to target Ca, Mg, alkalinity profile → Disinfect → Supply to production
After you submit — an engineer reviews within 24–48 h. No complete water analysis required to start; send available data and we will identify what is still needed.

Treatment train for bottled water plants and food production — fill-point quality from every source water type.
The treatment train for food and beverage water is a quality chain. Each stage protects the stages downstream and the product at the fill point. Skipping or undersizing any stage affects product quality, shelf life, or compliance status — not just equipment performance.
| Stage | Key Operating Parameter | Engineering Consequence if Undersized / Omitted |
|---|---|---|
| industrial activated carbon water filter | Mandatory ahead of RO; EBCT ≥ 10 min for free chlorine; ≥ 15 min for chloramine-bearing supply. | Residual chlorine above 0.1 mg/L oxidises polyamide thin-film composite membrane material irreversibly — salt rejection falls progressively and membrane requires early replacement. |
| RO membrane | Single pass: permeate ≤ 50 mg/L TDS; double pass: ≤ 10 mg/L for purified water classification. | Permeate TDS above target affects product taste, carbonation level, or ingredient water quality in every production batch. |
| uv disinfection water treatment (post-RO) | 254 nm; dose confirmed at rated flow and post-RO UVT; positioned in the post-RO distribution circuit. Final UV and 0.2 µm filter arrangement depends on filling-line hygiene design and product standard. | Without post-RO UV, any bacterial regrowth in distribution lines between the RO and fill point reaches the fill point unchecked. |
| ozonator for water treatment (storage tank) | Typically 0.1–0.4 mg/L where permitted; residual verified by in-line or routine measurement. Actual decay depends on water temperature, pH, organic load, contact time, and tank/pipework design. | Without ozone, biofilm establishes on tank interior and product water lines during the hold time between production runs — a recurring microbiological compliance risk. |
| Microporous filter (0.2 µm, fill point) | Final guard before fill; confirms microbiological barrier integrity at the point where water contacts the container. | Omitting the final barrier places full reliance on upstream equipment performing continuously at specification — a single upstream event passes through to product. |
Our industrial reverse osmosis machine configurations for food and beverage applications are sized to feed water chemistry and target permeate TDS — not to a standard product table. The activated carbon EBCT, cartridge filter micron rating, and UV dose are all calculated from your source water analysis and daily production volume.
UV or ozone — selecting the right disinfection method
UV at 254 nm inactivates bacteria, viruses, and protozoa without adding chemical residue or altering TDS or taste. It is the standard post-RO disinfection stage in most bottled water plants. Ozone is used in the treated water storage tank to suppress biofilm formation during production hold time — it decomposes to oxygen before the fill point so sealed product carries no chemical residual. The two methods are complementary, not alternatives: UV for point-of-use inactivation, ozone for tank and line hygiene.
Bottled water TDS targets by production category
Purified water (drinking water standard): typical permeate TDS 10–50 mg/L after single-pass RO, pH adjusted post-RO. Natural mineral water: source-dependent TDS maintained, not reduced through RO — treatment is limited to filtration and UV. Beverage ingredient water: TDS target set by product recipe; some applications require double-pass RO for ≤ 10 mg/L or specific conductivity targets. We confirm the TDS and conductivity requirement before specifying the RO recovery rate and pass configuration.
Engineering variables reference.
These variables determine whether the system requires single-pass or double-pass RO, whether ozone is needed alongside UV, and how the activated carbon stage must be sized.
| Parameter | Typical Range | Engineering Consequence | Configuration Approach |
|---|---|---|---|
| Source water TDS | 50–2,000 mg/L | Determines RO configuration: single-pass achieves ≤ 50 mg/L permeate; double-pass achieves ≤ 10 mg/L for purified water classification. | Confirm product TDS specification before selecting RO pass configuration and recovery rate. |
| Activated carbon EBCT | ≥ 10 min for free chlorine; ≥ 15 min for chloramines | Below EBCT minimum, residual chlorine at RO membrane inlet degrades polyamide material irreversibly within weeks. | Sized from inlet chlorine concentration and flow rate; service life typically 12–24 months; replaced on breakthrough, not calendar. |
| RO permeate TDS | ≤ 50 mg/L bottled water; ≤ 10 mg/L purified water | TDS above product specification affects taste, carbonation level, or ingredient water quality in every batch produced. | Single-pass for most bottled water; double-pass for purified water classification or beverage ingredient applications below 10 mg/L. |
| UV dose (post-RO) | ≥ 40 mJ/cm² at rated flow and post-RO UVT | Below dose threshold, bacteria passing through RO distribution reaches the fill point unchecked. | UV positioned downstream of final 0.2 µm filter; lamp replacement at 8,000–12,000 hours; UVT measured at commissioning. |
| Ozone residual in storage | 0.1–0.4 mg/L; decomposes within 20–30 min at plant temperature | Without ozone, biofilm establishes on tank interior and product lines during hold time between production runs. | Contact tank volume sized for minimum 4 minutes ozone contact time; ozone not present in sealed product at fill. |
| Microporous filter at fill | 0.2 µm pore size | Omitting the final guard places full reliance on upstream equipment performing continuously at specification. | Positioned immediately downstream of UV steriliser; replaced at differential pressure trigger. |
| Source water hardness | 0–600 mg/L CaCO₃ | Hardness above 0.5 ppm at RO inlet causes CaCO₃ scaling on feed spacers within months. | Softening required where source hardness exceeds 150 mg/L; confirm from source water analysis before specifying. |
| Pre-RO turbidity | < 1 NTU | Turbidity above 1 NTU blinds activated carbon to organic breakthrough and reduces UV transmittance. | multi media filter achieves < 1 NTU before carbon stage; backwash triggered by differential pressure. |
| Product water microbiology | Confirmed by applicable drinking water, bottled water, or food safety standard; total coliform and E. coli limits must be verified by jurisdiction and product classification. | Exceedance triggers production halt, regulatory notification, and potential batch recall. | Validated multi-barrier approach: source control + RO/filtration + UV + ozone/storage hygiene + 0.2 µm final guard + routine microbiological monitoring — |
| Bromide / bromate risk | Bromide must be checked before ozone design — especially for groundwater, coastal water, or high-mineral sources | Ozone can convert bromide to bromate; bottled water bromate limits must be confirmed per destination market regulation. | Controlled by source bromide testing, ozone dose optimisation, contact time management, pH control, and post-ozone monitoring. |
