EQUIPMENTS FOR INDUSTRIAL RO
Reverse osmosis water filtration systems are commonly utilised to filter drinking water in industrialsettings. Heavy metals, pesticides, viruses, and bacteria are among pollutants that are removed using reverse osmosis technology. A reverse osmosis system's principal components are simple to maintain and operate at a reasonable cost.In power plants, industrial reverse osmosis (RO) equipment is only employed in the boiler water pre-treatment sector. Because most electric boilers run at high pressure (> 700 psi [4.8 MPa]), the quality of the boiler feed water must be very rigorous.
To do this, industrial reverse osmosis (RO) equipment is used, followed by a form of "purification", polishing equipment that reduces particles, particularly dissolved silica in supply water. This suggests that industrial reverse osmosis alone is incapable of producing the high-quality boiler feed water needed for high-pressure boilers.The scale of the polishing equipment for the demineralization of the power generation facility will be selected based on the performance of the industrial RO equipment (reduction in water quality and quantity). As a result, any issues with the RO device process will have a significant impact on the performance. The poor performance will result in a significant increase in expenses due to greater regeneration and acid/caustic use.Furthermore, the impact of defective industrial reverse osmosis equipment on power generating boilers could be substantial, potentially resulting in plant degradation and possibly boiler and turbine damage.
For the design of a Reverse Osmosis System, for a Power Plant,four primary components must be considered while designing producing facility which are:
- Array (Train)
Any reverse osmosis equipment system is incomplete without an industrial reverse osmosis component. The reverse osmosis process takes place only in this component.There are four key design elements:
1-Spiral Winding: The Most Popular Water Filtration Design is Spiral Winding.
2-Hollow Fibre: This architecture allows for very large membrane surface areas. It is employed in the desalination of saltwater.
3-Large Tube: In look and design, large tubes are similar to shell and tube heat exchangers. They're employed in a variety of applications, including food processing and wastewater treatment.
4-Flat Batten: A flat batten heat exchanger is similar to a plate and frame heat exchanger. It is used in the food processing industry.
To force pure water through the RO membrane and become permeate, high pressure and flow are required, regardless of the element design. Because high pressures are required, each element must be constructed so that the internal structures can resist a feed-water pressure of several hundred pounds per square inch.The number of elements required is determined by the amount of finished product required on a daily basis.The way the elements are joined together in the industrial RO equipment array, i.e. in series or parallel, is all that matters.
For the industrial RO stage:
1- Final water quality is required.
2- Daily amount of water is needed.
3- Inlet feed water quality is checked.
4- Cost to treat wastewater has to be considered.
5- Type of upstream feed water treatment equipment is required.
