Max Water 600 GPD Commercial 5-Stage Reverse Osmosis System with Dual Booster Pumps
Produce high-quality reverse osmosis water for maple syrup production, restaurants, hydroponics, beverage preparation, aquariums, offices, and other commercial applications with the Max Water 600 GPD Commercial Reverse Osmosis System.
This five-stage system combines sediment filtration, two carbon pretreatment stages, two 300 GPD thin-film composite membranes, and a final polishing carbon filter. Dual booster pumps help provide the operating pressure required for stable membrane performance under suitable feed-water conditions.
The system is designed to reduce total dissolved solids and a broad range of dissolved impurities from biologically safe feed water. Actual output and rejection depend on water pressure, temperature, TDS, hardness, pretreatment quality, membrane condition, and system backpressure.

Five Stages of Reverse Osmosis Filtration
-
5-Micron Sediment Prefilter — 20" x 2.5"
Captures silt, rust, algae, dirt, cloudiness, and suspended particles before they reach the carbon filters, booster pumps, and RO membranes. Typical replacement interval: approximately every 2–8 months. -
Granular Activated Carbon Prefilter — 20" x 2.5"
Coconut-shell GAC helps reduce chlorine, unpleasant taste, odor, pesticides, herbicides, and selected organic compounds before the water reaches the membranes. Typical replacement interval: approximately every 2–6 months. -
CTO Coconut-Shell Carbon Block Prefilter — 20" x 2.5"
Provides additional chlorine, taste, and odor reduction while helping protect the chlorine-sensitive TFC membrane elements. Typical replacement interval: approximately every 2–6 months. -
Dual 300 GPD TFC Reverse Osmosis Membranes
Two 2412-size thin-film composite membranes provide a combined nominal production capacity of up to 600 gallons per day. This stage reduces total dissolved solids and a broad range of dissolved organic and inorganic impurities. Typical replacement interval: approximately every 2 years, depending on feed-water quality and operating conditions. -
Inline GAC Polishing Postfilter
Provides final taste and odor polishing before the treated water reaches the storage or delivery point. Typical replacement interval: approximately every 2–8 months.

Maple Syrup Application Guidance
Reverse osmosis can be used in maple syrup operations to remove a portion of the water before boiling. This can reduce the volume that must be evaporated, shorten boiling time, and lower fuel or energy consumption.
Hydroponic Application Guidance
Reverse osmosis water provides a lower-mineral starting point for preparing hydroponic nutrient solutions. This allows growers to manage nutrient concentration more precisely than when using source water with high or variable mineral content.
Feed-Water Pretreatment Requirements
Water containing hydrogen sulfide, rotten-egg odor, elevated iron, sulfur, manganese, or sulfur-reducing bacteria should be properly treated before it reaches the RO system.
Without adequate pretreatment, these contaminants may cause membrane fouling, slime formation, mineral buildup, unpleasant odor, and reduced water production. Hydrogen sulfide may also oxidize into sulfur particles that clog filters and membrane surfaces.
Reverse osmosis membranes are not intended as the primary treatment for hydrogen sulfide odor. Install suitable iron, sulfur, manganese, or disinfection equipment ahead of the RO system when testing shows these conditions are present.
The supplied product information limits feed-water TDS to approximately 1,000 ppm. Water above this level, or water with high hardness, requires proper pretreatment and may not be suitable for the standard configuration.
A properly sized water softener and compatible antiscalant treatment may help minimize membrane scale, improve efficiency, and extend membrane service life.
Liquid-Level Control Recommendation
To reduce frequent pump cycling and help protect the booster pumps, consider using the commercial liquid-level control switch, Part No. 105050 .
A compatible level-control system can provide more reliable storage-tank operation than basic float-valve arrangements. Final controls must be selected and wired according to the pump, tank, electrical supply, and installation design.
Installation and Maintenance Information
- Test the source water for TDS, hardness, iron, manganese, sulfur, chlorine, pH, and microbiological quality before installation.
- Install suitable pretreatment whenever source-water conditions exceed the RO system requirements.
- Connect the feed-water, product-water, and drain tubing according to the supplied flow diagram.
- Do not operate either booster pump without adequate incoming water supply.
- Install and test the low-pressure switch, high-pressure switch, and solenoid valve before continuous operation.
- Flush all new prefilters, postfilter, and RO membranes before using the product water.
- Replace sediment and carbon prefilters before chlorine or heavy sediment reaches the RO membranes.
- Monitor feed-water and product-water TDS regularly with a calibrated meter.
- Sanitize the housings, tubing, storage tank, and product-water pathway during scheduled maintenance.
- Check tubing, fittings, switches, pump operation, and drain flow regularly for leaks or abnormal performance.
Frequently Asked Questions
Does this system always produce exactly 600 gallons per day?
No. The 600 GPD figure is a nominal membrane rating. Actual output varies with feed-water pressure, temperature, TDS, hardness, backpressure, membrane condition, and pretreatment performance.
Why does the system use two 300 GPD membranes?
Two membranes allow the system to achieve a combined nominal production capacity of up to 600 GPD while using compact 2412 membrane elements.
Why are two booster pumps included?
The two-pump configuration supports the two membrane channels and helps provide the operating pressure needed for higher-capacity production. Adequate source-water flow and correct electrical controls are still required.
Can this system be used for maple syrup production?
It may be suitable for selected maple-sap concentration applications, but the final system must be evaluated for sap temperature, sanitation, membrane compatibility, production goals, and applicable food-processing requirements.
Can this system be used for hydroponics?
Yes. RO water can provide a low-mineral starting point for nutrient preparation. Growers must add the required nutrients back and monitor EC, pH, calcium, magnesium, and nutrient concentration.
Is this a conventional whole-house system?
No. It is a commercial RO production system rated in gallons per day. It is better suited to storage-tank filling or controlled product-water applications than unrestricted whole-house peak flow.
Why are both GAC and CTO carbon filters included?
The GAC filter provides initial chlorine, taste, odor, and organic reduction. The CTO carbon block provides an additional chlorine-removal and polishing stage before the chlorine-sensitive TFC membranes.
Can this system operate from a storage tank?
Yes, when the storage tank, level controls, pressure switches, tubing, and delivery system are properly sized. A compatible liquid-level control is recommended to reduce rapid pump cycling.
How often should the prefilters be replaced?
The supplied guidance lists approximately 2–8 months for the sediment and post-carbon filters and approximately 2–6 months for the GAC and CTO prefilters. Actual intervals depend on water quality and system use.
How do I know when the RO membranes need replacement?
Compare feed-water TDS with product-water TDS using a calibrated meter. A sustained decline in rejection or production after pressure, temperature, and prefilter condition are checked may indicate membrane fouling or the need for replacement.
Can this system be used on well water?
It may be used with properly tested and pretreated well water. Iron, manganese, sulfur, hydrogen sulfide, hardness, sediment, and bacteria must be treated before the RO system when present at problematic levels.
Why is a water softener recommended for hard water?
Calcium and magnesium can form scale on the membrane surface. Proper softening and antiscalant treatment can reduce scaling, support stable production, and extend membrane life.
TDS = Total Dissolved Solids. GPD = Gallons Per Day. GAC = Granular Activated Carbon. CTO = Chlorine, Taste, and Odor. TFC = Thin-Film Composite.
