How to select the best Reverse Osmosis Pre filtration system?
The reverse osmosis system, which typically produces pure water, has filter pores with a size of 0.0001 microns. Before the reverse osmosis, a pre-filtration system is installed to stop bigger contaminants from entering the system and causing obstruction.
Stainless steel, FRP, and micron filters systems are typically used in the RO Plants. Let's examine how to select an appropriate reverse osmosis pre-filtration system.
· Filtration System made of Stainless Steel
The filter housing and filter consumables make up the majority of stainless steel filter systems. High Flow Filter, Depth Filter Cartridge, or Liquid Filter Bag with a 5 micron rating are the most common filter consumables.
Stainless steel filter housing is typically used for liquid filtering with low salt concentration, because liquids with high salt content damage them.
1. A high-flow filtration system made of stainless steel
The pre-filtration system can directly employ a stainless steel filter housing with one or more high flow filters of varied specifications, or link multiple stainless steel filter housing in parallel, depending on the influent flow requirements of reverse osmosis.
2. Stainless Steel Cartridge Filter
The pre-filtration system can employ a single set of stainless steel filter housing or several sets, each housing running in parallel with a different set of depth filter cartridges with varying specifications.
3. System of Stainless Steel Bag Filters
Stainless steel bag filter housing and liquid filter bags are the typical components, of a stainless steel bag filtration system. The pre-filtration system can decide to use one or more parallel stainless steel filters directly, depending on the demands of the reverse osmosis influent flow.
· Fiber-reinforced plastic (FRP) filtering system
The high flow filter, liquid filter bag, melt blown cartridge, and FRP filter housing make up the majority of the FRP Filtration System. It is typically utilized in high-salt liquids like seawater and brackish water desalination, among others.
1. High flow filtration system made of FRP
The FRP high flow filter housing and High Flow Filter Cartridge typically make up the high flow FRP filtration system. According to individual requirements, you can select a vertical type or horizontal type high flow filter housing, and a matching number of different model high flow cartridge filters.
2. FRP Cartridge Filtration
Melt Blow Filter Cartridge and FRP Cartridge Filter Housing make up the majority of the FRP Cartridge Filtration System. The pre-filtration system can opt to employ a single unit or multiple FRP cartridge filter housing, with melt blown cartridge filters of varied lengths operating in parallel, depending on the demands of the reverse osmosis influent water.
· PPH filter
PPH (Polypropylene Homopolymer) filter housing with filtration consumables like high flow filter cartridge, liquid filter bag, or depth filter cartridge with 5 micron, make up most plastic filtration systems. The majority of the times extremely corrosive liquid filtration environments use PPH filtration systems.
1. PPH High Flow Filtration System
PPH high flow filter housing and a high flow cartridge filter are the typical components, of a plastic high flow filtering system. The pretreatment system can opt to directly employ one or several plastic filter housing, with 30" high flow filters running in parallel to meet the flow requirements of reverse osmosis influent water.
2. PPH Cartridge Filtration System
The depth filter cartridge and plastic filter housing make up the majority of the plastic cartridge filtration system. To create the pre-filtration system needed for a RO system, you can utilize one or more plastic (PPH) filter housing connected in parallel, as well as numerous depth filter cartridges measuring 20 inches or 30 inches.
Conclusion
When designing and choosing a RO pre-filtration system, it is important to determine which components and corrosion strengths the filtrate contains. You must also choose a filter housing and filter consumable that are compatible with the filtrate. Finally, you should compare the filtration costs of various solutions, and select the one that is most appealing in terms of both price and quality.
