4 Stage Value 75GPD RO/DI System - Bulk Reef Supply

BRS 4 Stage Systems are perfect for reefers who have water treated with chlorine or relatively clean well water. The 4 stage systems are self-contained on a single bracket making them ideal for tight spaces or where a non-permanent connection may be required. Installing a RO/DI system only takes a few minutes and can be done very easily without any permanent modifications to your home or the plumbing.

4 Stage Value RO/DI Features:

• Multiple source water connections
• Mur-lok Push Connect dual EPDM O-Ring fittings
• 10 Ft Each of 1/4" Blue, Red and Black Tubing
• Pre-installed NSF Certified Filters 

 All Bulk Reef Supply RO/DI Systems are covered by our Limited Lifetime Warranty.

Bulk Reef Supply RO/DI systems only use the latest filters and components in Reverse Osmosis technology. We have designed our RO/DI units especially for reef tanks, but they can produce perfect water for other types of saltwater and freshwater aquariums too. If you have a well, or you are connected to city water we provide a variety of RO/DI systems that will fit your aquarium's needs.

4 Stage RO/DI Systems - Perfect for city water that is treated with low amounts of chlorine, or well water with very minimal contaminants.
5 Stage RO/DI Systems - Our most popular system handles most types of well water along with most types of city water treated with chlorine including small amounts of chloramines.
6 Stage RO/DI Systems - If you are not sure what is in your water, or it contains excessive amounts of TDS or hard to remove contaminants like chloramines, phosphates, nitrates, silicates, etc. The BRS 6 Stage systems are designed to treat any water your home may have effectively. The Dual DI stage helps with the hard to remove ions like ammonia, phosphates, silicates, etc.

4 STAGES OF FILTRATION

Stage 1

Purtrex 5 Micron Depth Sediment Filter 

Sediment filters trap debris and other free-floating particles that would normally clog expensive carbon blocks and foul membranes. Purtrex filters are a true depth filter with a graded density that progressively gets tighter through as water passes through the filter allowing them to last longer than the competitors.

Stage 2

BRS 5 Micron VOC Block  (Chlorine 15,000 @ 1 GPM)

Our VOC carbon blocks are specially formulated to remove and reduce chlorine and volatile organic compounds from household water.

Stage 3

75 GPD Dow Filmtec Membrane (up to 99% rejection rate*)

DOW is hands down the industry leader for residential RO membranes. The 75 GPD Filmtec membrane can remove up to 99% of contaminants from traditional household drinking water. All membranes do require pressure to operate correctly, and DOW's membrane only requires 50 PSI of feed pressure to operate efficiently. For more info on DOW membranes - Click Here

Stage 4

Nuclear Grade Color-Changing Deionization Resin

Deionization resin is the final stage of the RODI system and will polish your water down to 0 TDS. The DI resin is a mixed bed with a color changing indicator to let you know when it is becoming depleted. The resin starts as a dark blue color that will turn gold when as it becomes exhausted and is a good indicator to let you know when to it should be replaced.

4 Stage Value RO/DI System Recommended Conditions:

• Minimum Water Pressure - 50 PSI
• Max Water Pressure - 90 PSI
• Recommended Water Temperature - 77°F
• Recommended Max TDS - <300ppm

Water pressure can be increased by adding a booster pump before your RO/DI system if a pressure increase is required. Low pressure will cause slow production of product water, with excess production of waste water. Pressure over 90 PSI may cause damage to the RO/DI units filters and components.

*DOW Filmtec 75 GPD Membranes have a 96% - 99% typical stabilized salt rejection rate that can be reproduced through the following conditions;

• Source Water Pressure - 50 PSI / Membrane
• Source Water Temperature - 77°F
• Source Water TDS - 250ppm Softened Tap Water
• Recovery - 15%
• Minimum Salt Rejection - 96%
