Reverse Osmosis Water Treatment Plant

Reverse Osmosis water plant

Since 1983, we’ve been the industry leader in RO expertise and membrane applications.

Applied Membranes has been at the forefront of reverse osmosis technology for nearly four decades, incorporating all advancements in the technology into our product lines to provide the greatest levels of performance and reliability available today. Membrane elements are designed and manufactured by AMI for a wide range of applications and water issues. Our knowledge in membrane technology is mirrored in our reverse osmosis systems, resulting in water treatment solutions that provide the greatest levels of performance currently accessible.

What is Reverse Osmosis?

RO is a membrane separation water purification technique in which feed water flows under pressure along the membrane surface. Purified water passes through the membrane and is collected, whereas concentrated water, which contains dissolved and undissolved debris and does not pass through the membrane, is released into the drain.

A membrane and water under pressure are two of the most important requirements for the Reverse Osmosis (RO) process. Prefiltration to remove suspended contaminants and carbon to remove chlorine are two more requirements (damages the membrane).

Depending on the pollutant and the nature of the water, most membranes remove 90-99 percent of dissolved impurities.

When paired with pre-filtration, reverse osmosis can remove 90 to 99.99 percent of the dissolved contaminants in your water.

Salts, bacteria, and numerous high molecular weight organics are removed via reverse osmosis systems (RO Systems). The capacity of the system is determined by the water temperature, total dissolved solids in the feed water, operating pressure, and overall system recovery.

How does a Reverse Osmosis Water Treatment Plant work?

A prefilter removes sediment and chlorine from the water before forcing it through a semipermeable membrane to remove dissolved particles in a reverse osmosis system. Before entering a dedicated faucet, water departs the RO membrane and flows through a postfilter to polish the drinking water. The quantity of prefilters and post-filters in a reverse osmosis system determines the stages.

The stages of a RO system

A reverse osmosis system is centered on the RO membrane, but it also contains other types of filtrations. RO systems have three, four, or five stages of filtration.

  • A sediment filter and a carbon filter are included in every reverse osmosis water system, in addition to the RO membrane. Depending on whether water travels through them before or after passing through the membrane, the filters are referred to as prefilters or post-filters.
  • One or more of the following filters are found in each system type:
  • Filter for sediment: Reduces particles such as dirt, dust, and rust.
  • VOCs, chlorine, and other pollutants that give water a foul taste or odor are reduced by using a carbon filter.
  • A membrane that is semi-permeable: Up to 98 percent of total dissolved solids are removed (TDS)
  1. Prefiltration is performed on the water before it enters a RO system. To remove sediment and chlorine that could clog or harm the RO membrane, prefiltration usually includes a carbon filter and a sediment filter.
  2. The water next passes over a reverse osmosis membrane, which removes dissolved particles that are too tiny to be detected with an electron microscope.
  3. Water goes from the filtration system to the storage tank, where it is kept until it is needed. A reverse osmosis system filters water until the storage tank is full, at which point it shuts off.
  4. When you turn on your drinking water faucet, water from the storage tank passes through another postfilter, which polishes the water before it reaches your faucet.

What is the purpose of a RO storage tank?

An RO storage tank stores reverse osmosis water so that you always have enough when you need it. A reverse osmosis system takes a long time to produce water. Two to three ounces of RO water are produced in one minute. If you turned on the faucet for a glass of water at the current membrane production rate, it would take at least 5 minutes for it to fill. Your glass fills up quickly with a storage tank.

Benefits

RO (Reverse Osmosis) Systems are used to purify water. Total Dissolved Solids (TDS) can be removed up to 99 percent of the time.

Reverse osmosis is a membrane separation method in which feed water flows under pressure along the membrane surface. Purified water passes through the membrane and is collected, whereas concentrated water, which contains dissolved and undissolved debris and does not pass through the membrane, is released into the drain. Salts, bacteria, and numerous high molecular weight organics are removed via reverse osmosis systems. The capacity of the system is determined by the water temperature, total dissolved solids in the feed water, operating pressure, and overall system recovery.

The Benefits of Reverse Osmosis Over Other Processes

Reverse osmosis has proved to be the most effective method of eliminating salts, chemical pollutants, and heavy metals like lead from drinking water when compared to other traditional water treatment methods. Reverse osmosis is less expensive than ion exchange for waters with total dissolved solids of 200 or higher. It is favored over ion exchange for the removal of silica and organics even when total dissolved solids are less than 200. Reverse osmosis uses a fraction of the total energy of distillation and does not have high-temperature issues, scaling, or corrosion. Today reverse osmosis systems have proven to be the most economical and efficient means of improving the quality of water.

It’s easy to use and maintain.

Reverse osmosis systems from Applied Membranes are fully assembled, factory tested, and ready to use. They are simple to use and maintain and are designed for efficiency. Membranes must be replaced every one to three years, depending on water quality, system size, and pretreatment, in addition to frequent monitoring and cleaning. Pumps also need to be serviced on a regular basis.

What is the average lifespan of a reverse osmosis system?

The average lifespan of a reverse osmosis system is 10 to 15 years. While the systems themselves are long-lasting, the RO membrane and filters must be replaced on a regular basis. Prefilters and post-filters should be replaced every 6 to 12 months. The RO membrane should be updated every 2-4 years, depending on your water conditions.

Here are a few pointers to help you keep your reverse osmosis system in good working order.

This RO Troubleshooting Guide will assist you in identifying and correcting any issues with your RO system.
