The purified water is collected in the storage tank, while the concentrated stream is typically discharged as wastewater.

Reverse osmosis storage tanks are typically made of durable materials such as polyethylene or fiberglass and are designed to withstand the pressure generated by the RO system. They are usually equipped with a pressure gauge, a drain valve, and a level sensor to monitor the water level and maintain optimal system performance. The storage tank plays a vital role in ensuring a continuous supply of purified water, eliminating the need for constant operation of the RO system.

The benefits of using a reverse osmosis storage tank include improved water quality, reduced maintenance costs, and extended RO system lifespan. By storing purified water, the tank allows the RO system to operate intermittently, reducing energy consumption and wear and tear on the system components. Additionally, the storage tank provides a reserve of clean water in case of power outages or other emergencies.

1. Capacity

The capacity of the reverse osmosis storage tank is a crucial factor to consider when selecting a system for your home or business. The capacity determines how much purified water can be stored, which in turn affects how often the RO system needs to operate to replenish the supply. A larger capacity tank will require less frequent operation of the RO system, which can save energy and extend the life of the system.

• Daily water needs: The first step in determining the appropriate capacity for your storage tank is to estimate your daily water needs. Consider how many people live in your household or work in your business, and how much water they typically use for drinking, cooking, cleaning, and other purposes.
• Peak water usage: Once you have estimated your average daily water usage, you need to consider your peak water usage. This is the time of day when you are most likely to use a lot of water, such as during the morning when everyone is getting ready for work and school, or in the evening when everyone is cooking and cleaning up.
• RO system production rate: The production rate of your RO system will also affect the size of storage tank you need. The production rate is measured in gallons per day (GPD), and it indicates how much purified water the system can produce in a 24-hour period. A higher production rate will require a larger storage tank.

By considering these factors, you can select a reverse osmosis storage tank with the appropriate capacity for your needs. A properly sized storage tank will ensure that you always have a supply of clean, purified water on hand, even during periods of peak usage.
