Water Treatment Systems

For a 500 mL PET line running 10,000 bottles per hour on a continuous reverse osmosis system feed over 16-hour shifts, you are producing roughly 80 m³ of finished purified water per day once you account for the rinser, CIP cycles, and quality reject volume. That places the system at the MS-RO-5000 tier (5 T/H, ~120 m³/day) with comfortable headroom — we recommend sizing one tier above your bottling rating so the RO does not become the line bottleneck during peak shifts. The MS-RO-10000 tier becomes appropriate once you scale to 18,000–24,000 BPH or run continuous three-shift operations.

A carbon-only setup strips free chlorine and improves taste, but it does nothing about sediment above 5 microns, calcium and magnesium hardness, or dissolved solids in general. Running an RO membrane downstream of carbon-only pretreatment is the single most common cause of premature membrane failure in low-cost commercial systems — hardness scales the membrane and forces CIP cycles within months instead of years. Our four-stage stack (sand → carbon → softener → micron filter) brings SDI below 3 and free chlorine to non-detectable before the feedwater reaches the RO main, which is what allows the membrane to run toward the upper end of its industrial lifespan range of five to seven years.

Both. Our commercial RO water treatment system on this page covers the water-side path from raw water intake to storage tank — pretreatment, RO main, UV, ozone, and finished-water tank. For a turnkey bottling plant we extend the package downstream with filling lines (2,000–36,000 BPH for water, 50–2,000 BPH for 5-gallon barrels), heat-shrink labeling, OPP hot-melt labeling, bottle blow molding, and PET preform production. An integration advantage is one supplier for the full water-to-pallet path, which removes the interface coordination issue we see when buyers buy water treatment and filling lines from separate vendors.

DOW FilmTec BW30 elements are rated at 99.5% NaCl rejection minimum under the manufacturer’s standard test condition (2,000 ppm NaCl at 225 psi, 25°C, pH 8, 15% recovery). In real plant operation, system-level desalination lands in the 97–99.6% range depending on feedwater composition, recovery rate, and how long the membrane has been in service. Our engineers commission every plant against your specific feedwater profile during the FAT cycle, so the desalination rate you see in operation is documented before the system leaves our facility.

Industry data shows commercial RO membranes last three to five years on average, while industrial RO membranes reach five to seven years when the pretreatment is sized and maintained properly. Replacement frequency depends almost entirely on what reaches the membrane — feedwater quality, the integrity of the carbon stage chlorine removal, the softener regeneration cycle, and the quarterly CIP discipline. In a five-year operating window, a well-run plant on our specification typically sees one full membrane replacement cycle; under-pretreated plants see two or more. Membrane line item is one of the largest five-year OPEX components and the easiest one to extend through pretreatment investment.

Yes. Ladder above lists standard MS-RO model points, but the underlying chassis is modular — element count, pump sizing, and storage tank volume configure between tiers. A modular chassis lets us build 1.5, 3, 7, 15, 25 and 30 T/H plants when your bottling rating sits between standard rungs, with the 30–45 day lead time holding below MS-RO-10000.

The two-year warranty covers all machine parts on the commercial RO water treatment system — pumps, valves, control panels, instrumentation, frame, piping, and tank welds — for the full 24 months from FOB delivery. Consumables (RO membranes, UV lamps, cartridges, resin, ion-exchange media) are excluded because their lifespan depends on your operating conditions rather than build quality. A 24-hour engineer response means an application engineer from our Zhangjiagang team responds to your technical query within one business day across email, WhatsApp, and scheduled video calls; for warranty-covered failures, replacement parts dispatch via international courier within five working days.

Every plant of MS-RO-2000 capacity and above ships with on-site installation and operator training as part of the standard scope, scheduled jointly with your project timeline. Site work covers the system positioning, piping interconnect to your existing water source and bottling line, electrical and instrumentation commissioning, and a multi-day operator training program covering routine operation, CIP discipline, and the maintenance schedule that keeps the membrane on the longer end of the industrial lifespan range. Each Factory Acceptance Test runs at our facility against simulated feedwater matching your site analysis, and the FAT report — including permeate water quality logs across the test cycle, free chlorine and SDI readings at each pretreatment stage, and the recovery rate against your specified TDS — ships with the system records for your QA file. Where local regulations require a Site Acceptance Test, our engineers run that on your floor after commissioning is complete, with sign-off documentation prepared in the format your regulatory body or QMS framework requires. For plants exporting to the United States, European Union or GCC region, we coordinate the additional documentation packages that customs and food-safety authorities typically request during the import or registration cycle, so your bottled water plant can begin commercial operation on schedule rather than waiting for paperwork in transit.
