What is RO or Ion exchange treatment of effluent water?
Water purification is a critical step in ensuring that the community has access to safe drinking water. Water purification is a multi-stage process that includes biological, chemical, and physical approaches. Ion exchange and reverse osmosis are two methods for purifying water. Both of these devices can remove dissolved particles from water. In some water purification processes, a combination of these technologies is used. Both are also frequently employed in a variety of sectors.
What's the difference between ion exchange and reverse osmosis?
you might wonder! If you're not sure how IX and/or RO might fit into your workflow, the following article compares the essential traits, benefits, and drawbacks of both IX and RO.
What is Ion exchange Process?
Ion exchange is a method of demineralizing wastewater and softening drinking water. This approach involves exchanging ions with another ionic species to remove ions from an aqueous solution. In this way, weakly bound ions can be displaced by a robustly binding ionic species. Ion exchange can be performed in batches or in real time. It is used in the purification of wastewater to remove nitrogen, phosphorus, and heavy metals. It's also used to remove pollutants selectively and recover essential trace elements including chromium, nickel, copper, lead, and cadmium from industrial waste discharges.
What is Reverse Osmosis?
Reverse osmosis is a system which allows water to pass through a semi-permeable membrane by supplying a pressure to the system that is higher than the hydraulic pressure. The movement is guided by a concentration gradient. The membranes used in reverse osmosis are known as reverse osmosis (RO) membranes. Almost all particles, including pathogens, organic materials, ions, and other particulate matter, may be filtered out by RO membranes.
Ion exchange Vs Reverse Osmosis
Ion exchange (IX) and reverse osmosis (RO) are two techniques that can be used to solve some of the same separation issues, and they're sometimes combined.IX and RO, on the other hand, differ in a number of ways that have an impact on their overall acceptability and cost-effectiveness in a given process or application.
Ion exchange is a physio-chemical approach for selectively removing pollutants by effectively exchanging ions with identical electrical charges, whereas reverse osmosis is a physical process in which water is forced through a semi-permeable membrane against a concentration gradient.
Comparison of RO andIX technology
1) RO purity remains constant, whereas IX quality deteriorates as the resin approaches renewal.
2) IX chemicals are more expensive than RO chemicals, therefore operating costs per gallon of cleaned water are higher.
3) RO membranes create a physical barrier that keeps bacteria, viruses, algae, and suspended solids out, whereas IX systems don't.
4) IX regenerates the resin beds with two hazardous chemicals: hydrochloric acid (HCl) and caustic soda (NaOH); these chemicals require particular storage and disposal.
5) The continuous concentrate effluent from RO systems is 15-35 percent, however it does not need to be treated before being discharged to drain.
6) Because RO cleaning chemicals are non-hazardous, no additional handling, storage, or disposal procedures are required.
7) In comparison to IX systems, RO systems are less expensive to operate and need less effort to maintain.
