6,000L Automated RO / DI Water Purification System

Approx. 1,200L/day RO/DI production • 6 × 1,000L IBC storage tanks • RO + DI + UV + polishing • Automated filtration and transfer • Optional 150L/day distillation upgrade

Offered for sale is a substantial custom-built commercial reverse osmosis and deionised water purification system, designed as an integrated automated water-treatment plant rather than a single filtration unit. The system has now been dismantled and is held in storage in County Durham.

The complete installation combines pre-treatment, reverse osmosis, deionisation, water polishing, UV purification, silica filtration, water-quality monitoring, high-pressure pumping and approximately 6,000 litres of total storage capacity.

The system is capable of producing approximately 1,200 litres of RO/DI water per day, depending on incoming water quality, pressure, temperature, filter condition, membrane condition, resin condition and operating parameters.

Potential applications include commercial window cleaning, vehicle detailing, manufacturing, laboratories, aquariums, hydroponics, controlled-environment agriculture, precision rinsing, specialist horticulture and other processes requiring purified or low-conductivity water.

The installation includes 6 × 1,000-litre IBC tanks, providing approximately 6,000 litres total storage capacity.

The multiple-tank arrangement allows water to be staged, transferred or stored at different points within the purification process depending on the configured operating method.

A substantial steel IBC support frame is also included, measuring approximately 300cm × 120cm.

The primary purification stage includes a 6-stage cartridge-filter reverse-osmosis filtration unit.

This system provides staged pre-filtration before reverse osmosis treatment, reducing contaminants and dissolved solids before the water progresses through the additional deionisation, UV and polishing stages.

Following reverse osmosis, the system incorporates a 3-stage resin-filter deionisation system.

This provides an additional purification stage intended to remove remaining dissolved ionic contaminants and further reduce conductivity/TDS, subject to resin condition, configuration and incoming water quality.

• 1 × 5-stage final water-polishing unit with integrated UV light
• 1 × 3-stage pre-water-polishing unit
• 1 × high-pressure commercial UV water-purification unit

These additional treatment stages provide further polishing and UV treatment beyond the main RO and DI processes, creating a comprehensive multi-stage purification system.

Included is a high-pressure silica-media water-filtration unit with automatic cleaning function.

This forms part of the pre-treatment infrastructure and is designed to help remove suspended contaminants before water progresses through finer treatment stages.

The system was designed to operate as a largely automated water-production and storage installation.

Water can be processed through the filtration stages and transferred between the integrated storage tanks using the installed pumps, valves, controls and associated infrastructure.

The system includes 4 × high-pressure water pumps used throughout the filtration, transfer and pressure-management stages.

The installation includes 2 × inline water heaters, allowing water temperature to be managed where required within the treatment process.

Water temperature can influence RO membrane performance and production efficiency, making temperature management useful in some operating conditions.

Included is 1 × inline water-quality monitoring meter capable of providing up to 8 water-quality readings / monitoring values, subject to configuration and calibration.

This allows the operator to monitor water quality and assess purification performance across the system.

• 6 × 1,000-litre IBC tanks
• 1 × 6-stage cartridge-filter reverse-osmosis filtration unit
• 1 × 3-stage resin-filter deionisation unit
• 1 × 5-stage final water-polishing unit with integrated UV light
• 1 × 3-stage pre-water-polishing unit
• 1 × high-pressure silica water-filtration unit with automatic cleaning function
• 1 × high-pressure commercial UV water-purification unit
• 2 × inline water heaters
• 1 × inline water-quality meter with up to 8 monitored readings / values
• 4 × high-pressure water pumps
• 1 × steel IBC tank support frame, approx. 300cm × 120cm
• Associated installed pipework, flexible tubing, valves, connectors, pressure fittings, filtration housings and seller-owned control infrastructure forming part of the system

When combined with the main system, purified DI water can be further processed through distillation to create an additional high-purity treatment stage:

This optional configuration may be useful for applications requiring water that has undergone multiple independent purification processes.

• Approx. 6,000 litres total storage capacity
• Approx. 1,200 litres/day RO/DI production
• 6-stage RO filtration
• 3-stage deionisation
• 5-stage final polishing with integrated UV
• 3-stage pre-polishing
• Separate commercial UV purification
• High-pressure silica filtration with automatic cleaning
• 4 high-pressure pumps
• 2 inline water heaters
• Multi-point water-quality monitoring
• Optional approx. 150 litres/day distillation upgrade available separately

This is used specialist commercial water-treatment equipment. The system has previously been installed and operated and therefore shows normal signs of commercial use, including cosmetic marks, water staining, surface marks, pipework wear and general signs of previous operation.

Filters, RO membranes, DI resin, UV lamps and other filtration media should be treated as service/consumable items.

Following relocation, the buyer should expect to carry out appropriate cleaning, flushing, sanitising, leak testing, filter/media inspection or replacement, membrane/resin checks, UV-lamp inspection, pump testing, meter calibration, electrical testing and recommissioning as required.

The system has already been dismantled and placed into storage in County Durham. The filtration stages, pumps, IBC tanks, controls, pipework and associated components are no longer assembled as an operating installation.

Prospective buyers should satisfy themselves as to the stored inventory, component condition, loading arrangements, transport requirements and the work required for reassembly and recommissioning.

Optional Reinstallation & Recommissioning

Subject to location, access, site suitability and prior agreement, unpacking, reassembly, reconnection, leak testing and basic recommissioning at the buyer’s new location may also be available at additional cost.

Consumables, replacement membranes, filters, resin, UV lamps, electrical works, certification and independent water-quality testing are not included unless specifically agreed within a separate quotation.
