Electro-deionisation is the latest and most modern of all water filtration techniques. The process sees the water through ion exchange membranes. It helps direct current electricity and ion exchange resin to effectively deionised water.
This process effectively removes the ionisable aqueous contaminants apart from the residual salts. For instance, it eliminates carbon dioxide, silica, ammonia and boron. These systems are chemical-free and give clean and fresh water.
The Kent RO service near me Bangalore provides servicing for filters that run on electricity. They do have some critical advantages over traditional ion exchange processes. The best thing about this process is that it uses less energy and yields more pure water.
The Process Of Deionisation
The electro-deionisation process functions on the principle of ion exchange. The ion exchange swaps the unnecessary ions for others with a similar charge. These ions get exchanged through the water purification process, and finally, the water gets purified and clean. The resin beads in the water purifier carry out the ion exchange process.
Conventional ion exchange process without electricity depends on the method of polymer resin beads. These beads attract unwanted ions. The ions build up over time on the resin beads. This saturation causes water pollution as they can re-enter the clean water. The ion-saturated water purifier beads need to get replaced from time to time.
However, in the electro-deionisation process in Kent RO Service Bangalore, the action gets carried out with the help of electricity. The electricity keeps the resin in good condition. There is a continuous flow of ions throughout the system. Therefore, the contaminants cannot saturate. The system stays in pristine condition for a long time. The resins regenerate continuously.
Trapping Ions And Removing Contaminants
The EDI or electro-deionisation process thoroughly removes all the particles. It is crucial to capturing electrolytes, minerals and other debris that are invisible to the naked eye. All these particles need to get filtered away while the ions and the minerals remain.
One administers EDI through a fixed and powered deionisation chamber already attached to the existing feed water system. The EDI systems are obscure and fast and come with an encased cylinder.
Functions Like An Ion Exchange Bed
The filter with the electro-deionisation process acts like an ion exchange bed. It goes through continuous electric regeneration. The ions get moved through the resins to filter out the particles. That happens with the help of the cation or anion-selective membranes. The membranes get charged either positively or negatively. This process, in turn, reacts to the ions in the water.
The H+ and the OH- ions get exchanged in the process. The ions become bound to the resins. They eventually end up in a separate chamber inside the filter. The extra ions get flushed out as water. Removal of excess and unnecessary ions are essential as it restores the water to its basic pH level.
Removes Carbon Dioxide
Here is where the electro-deionisation process gets all the extra credit. It is capable of removing carbon dioxide from water. It makes the water drinkable and fit for consumption. The process is not seemingly effortless, and carbon remains dissolved in water.
It makes it difficult to remove it. The EDI uses conductivity measurement to remove carbon dioxide from water. RO systems are incapable of removing carbon dioxide. Therefore, they rely on the EDI systems.
The EDI systems have the same process and other water purifying techniques. However, this process requires fewer automatic valves that do not need constant monitoring. This water treatment process may need only a few frequent electrode changes. This process is part of its maintenance schedule.
The system has reduced maintenance costs and labour costs as well. The ultra-purified water from the system is safe for consumption regularly. It also serves industry purposes, including pharmaceuticals. Electro-deionisation is an excellent process for a continuous flow of pure water without worrying about water pollution by chemicals and toxins.
Benefits of Electrodeionisation
EDI technology ensures that there is no build-up on the ion exchange beds. They get regenerated at regular intervals. The concentrates remove impurities, so they do not accumulate and exhaust the resin. This process means the ion exchange beds get operated in batch mode.
The electro deionisation process requires no chemicals to purify the water. This process is safe for the environment. All the ions get removed from the water, and they get collected for recycling and reuse purposes.
