RO systems require specialized storage tanks that can handle the pressurized outflows from RO processes. RO storage tanks also have unique sizing, construction, and material requirements to prevent and minimize contamination.
VARIABLES TO CONSIDER:
- Tank design (flat bottom versus cone bottom, seal or vented manway)
- Material of construction choices (most commonly polyethylene, FRP, or stainless steel)
Specialized storage should be used in concert with any RO application, including:
- Boiler feed water
- Ion-exchange pretreatment
- Rinse water
- Food ingredient water
- Safe drinking water
- Manufacturing / Automotive
- Laboratory / Universities
- Medical / Dialysis
FREQUENTLY ASKED QUESTIONS (FAQ’s):
Why do you need a specialized RO storage tank? RO tanks act as a pressure break for the RO system. Relieving back-pressure on the permeate line that would harm RO system performance.
Why do I need a cone-bottom tank? Cone bottom tanks are more sanitary than flat bottom tanks. Cone bottoms can be drained completely, and pump suction is on the lowest point in the tank, which allows more complete defection, and easier easy rinse out of disinfecting chemicals This is why con-bottom tanks are commonly used in high purity applications like laboratory grade and dialysis waters.
