Industrial RO Plant
An Industrial Reverse Osmosis RO Plant can be used in various industries, such as water treatment, wastewater treatment, and other processes. They are extremely versatile and easily installed on a modular facility, such as an ISO container. Because of their modular design, these plants are easy to transport to remote locations and can be installed anywhere that you need water purification. They also have an advantage over conventional filtration in that they can clean and disinfect large amounts of wastewater.
The feedwater entering the unit is under pressure, and the high pressure needed to overcome the osmotic pressure in the water is required to prevent the passage of dissolved salts and contaminants. The reject stream, also known as concentrate water, can be re-used, which allows for a recycling process of water. The permeate water, or product, results from the entire process and contains up to 99% dissolved salts.
The industrial Reverse Osmosis RO Plant can remove all contaminants from water. After the process, it can be stored in tanks or re-used. The membranes are made from cellulose acetate, a type of plastic, and they are made of highly resistant materials that will not dissolve in the water. The water from an Industrial Reverse Osmosis RO Plant is completely free from any traces of chemicals.
Use of Industrial Reverse Osmosis (RO) Plant in Various Industry
The main aim of an Industrial Reverse Osmosis RO Plant is to produce ultrapure water for various industrial applications. Typically, up to 50% of industrial RO plants are used to desalinate seawater. The remaining 40% produce highly-pure water for pharmaceutical, energy production, and electronic applications. The remaining 10% are designed to purify water for drinking and industrial purposes. The rejection coefficient of an Industrial Reverse Osmosis (RO) plant is greater than 90 percent.
Various industries require spot-free rinsing of their products, and hard water causes scaling and hard surface spots and bleaches metal structures. Reverse osmosis systems provide a clean and spot-free rinse to avoid damage to equipment and extend a product’s life. The use of industrial Reverse Osmosis RO Plant in different industries will enhance your company’s productivity.
A Reverse Osmosis system uses high pressure to force dissolved salts through the semi-permeable membrane. This removes the contaminants in water, leaving only the purified water. A Reverse Osmosis system requires little to no maintenance, and the membranes can last between two and three years. Because the membrane is self-contained, the RO system requires no human interaction from the operator.
How Industrial Reverse Osmosis RO Plant Work?
The main function of an industrial RO plant is to separate wastewater and purified water. The recovery rate depends on the type of membrane used in the system. For industrial applications, the pretreatment stage is often considered necessary, and it removes particles that can foul the membrane and damage the pumps. The pretreatment cartridge is usually made of string-wound polypropylene. For residential applications, pretreatment is not necessary.
The main component of the system is the reverse osmosis membrane. This semipermeable membrane is designed to remove a variety of contaminants from water. Next, the treated water passes through a pressurized storage tank. Finally, the treated water goes through a final post-filter, typically a carbon filter. This last step removes any remaining tastes and odors in the water.
The water passes through the membrane. Normally, the solvent moves from low concentration to high concentration, but this is reversed in reverse osmosis. Unlike in normal osmosis, the industrial RO system essentially reverses the flow of pure solvent. By reducing the difference in the solute concentration and water potential, Gibbs free energy and creates osmotic pressure.
Specification of Industrial RO Plant
In an industrial reverse osmosis (RO) plant, the recovery rate is the amount of water that passes through the membranes. The higher the recovery rate, the greater the purified water. It is important to note that a good RO system should also include a pretreatment lockout system. This prevents the RO system from running when the permeate storage tank is full. The RO plant should also include a softener regeneration lockout, which protects the membrane from scaling.
When choosing a system for an industrial setting, you must consider the feedwater characteristics. The quality of your feedwater will determine how much treatment is required. Hard water with a hardness of more than 15 grains will generally require an additional water softener or anti-scale injection unit. Additionally, water with a high iron, manganese, or sulfide level will need an oxidation unit. Chemical injection is the best choice for reducing scale potential, but it is not cheap and not suitable for large-scale installations.
In industrial-scale applications, reverse osmosis systems are designed with a two-stage system in mind. Each stage comprises a series of pressure vessels with a number of RO membranes. These vessels have a particular TDS and are used as separate stages in a system. The concentrate from the first two vessels is fed to the next vessel in a 2:1 array.
