Start from the water problem
What is your water doing wrong?
Six symptoms cover most commercial enquiries. Pick the one closest to your site to see the process that fixes it.
- 01 Hard water and scale Symptoms White spots on glassware, scale in boilers and hot-water loops, soap that will not lather. Treatment Ion-exchange softening, or antiscalant where salt is impractical. View system
- 02 High TDS and salty taste Symptoms Salty or metallic taste, white residue, TDS above 1,000 ppm, unsuitable for drinking or process. Treatment Single- or two-stage reverse osmosis, with blending if minerals are needed. View system
- 03 Iron and manganese Symptoms Orange-brown stains, metallic taste, dirty water after rain — common in boreholes. Treatment Oxidation by air, chlorine or ozone, followed by multimedia filtration. View system
- 04 Turbidity and sediment Symptoms Cloudy water, visible particles, cartridge filters clogging within weeks. Treatment Multimedia or sand filtration with automatic backwash, plus a 5 µm guard filter. View system
- 05 Bacteria and viruses Symptoms Positive coliform result, musty odour, contamination in storage tanks or pipework. Treatment UV at 30–40 mJ/cm² or ozone after filtration, with tank hygiene and recirculation. View system
- 06 Remote site, no plant room Symptoms No civil works, fast deployment needed, unstable grid, site far from a service team. Treatment Containerized plant from 4 to 25 m³/h, assembled and tested before shipment. View system

By venue
Where the systems are installed
The same train is configured differently for each building type. Open the venue closest to your project for the sizing formula and a recommended configuration.
-
01 Restaurants Clear ice, stable coffee and protection for dishwashers and steamers. -
02 Hotels Scale control in hot-water loops, laundry and guest drinking water. - 03 Offices Point-of-use drinking water without bottled-water logistics.
-
04 Schools Safe drinking water for canteens, dormitories and classrooms. -
05 Hospitals Microbiologically controlled water with continuous supply. - 06 Coffee shops Hardness and alkalinity balance for repeatable extraction.
Why buyers trust us
A factory, not a trading office
Stainless frames, tanks and pipework are fabricated in-house. Every unit is pressure-tested and run before packing, and ships with drawings, a test record and a spare-parts list.
- In-house stainless fabrication — frames, vessels and pipework
- Pressure test and run test on every unit before shipment
- CE and ISO 9001 documentation supplied with the equipment
- 12–18 month warranty, spare parts and remote support
- 01
Incoming inspection
Membranes, valves, pumps and instruments checked on receipt.
- 02
Welding and passivation
Stainless frames and vessels welded and passivated in-house.
- 03
Pressure test
Hydro-test at design pressure before electrical connection.
- 04
Run test and calibration
Flow, pressure, recovery and conductivity verified and recorded.
How buying works
From inquiry to commissioned plant
A project moves through five stages. You receive an itemised quotation, drawings and a factory test record before shipment.
- 1
Water analysis and demand
Lab report, daily and peak demand, site conditions and target standard.
- 2
Process design and quotation
Train, membrane area, pump duty and recovery fixed; equipment quoted line by line.
- 3
Fabrication
Frames, vessels and pipework welded, passivated and assembled.
- 4
Factory test
Pressure test, run test and calibration recorded for each unit.
- 5
Shipping and commissioning
Documentation, installation guidance, commissioning and operator training.
What you receive
Typical lead time: 15–30 days for standard skids, 30–60 days for containerized and turnkey plants, counted from drawing approval and deposit. OEM branding, nameplate and documentation are available.
- Itemised quotation with scope and exclusions
- P&ID and layout drawing for approval
- Factory pressure and run test record
- O&M manual and spare-parts list
Reference configurations
Eight trains that cover most enquiries
Use these as a starting point, not a quotation. Final capacity and train follow the water analysis.
| Application | Flow | Process train | Notes |
|---|---|---|---|
| Hotel, 100 rooms | 2–4 m³/h | Multimedia + carbon + softener + RO + UV | Protects hot-water loop and laundry; supplies guest drinking points. |
| Restaurant, 120 seats | 1–2 m³/h | Carbon + softener + RO + UV | Ice machines, coffee, dishwashers and steamers. |
| Factory or well water | 10–20 m³/h | Oxidation + multimedia + softener + two-stage RO | Iron and manganese removal; higher recovery for process use. |
| Office, 200 staff | 1–1.5 m³/h | Carbon + RO + UV + storage | Drinking, coffee and pantry points; replaces bottled water. |
| School, 1,000 students | 2–3 m³/h | Multimedia + carbon + RO + UV + loop | Break-time storage, canteen and classroom fountains. |
| Hospital, 150 beds | 3–6 m³/h | Multimedia + carbon + softener + RO + UV | Continuous supply and microbiological control; separate clinical stream. |
| Coffee shop, 300 cups/day | 0.3–0.6 m³/h | Carbon + softener + RO + blending | Stable extraction and clear ice; blend to target mineral level. |
| Remote camp or community | 4–10 m³/h | Containerized oxidation + multimedia + RO + UV | Prefabricated and tested; unattended operation with remote monitoring. |
Reference configurations only. A quotation is issued after the water analysis and site survey.
