We provide complete solution including Bulk storage tanks and storage tanks, transfer pumps. Demineralised Water also known as Deionised Water has its mineral ions removed. Mineral ions such as cations of Sodium, Calcium, Iron, Copper, etc. Because the majority of water impurities are dissolved salts, deionization produces a high purity water that is generally similar to distilled water, and this process is quick and without scale build-up.
Demineralised water systems are the main equipment used in the preparation process of high purity water and treatment water. It consists of following:. There are two basic types of resins: Cation Exchange and Anion Exchange resins.
Anion exchange resins will release hydroxyl OH- ions or other negatively charged ions in exchange for impure anions present in the water. Degasser Tower is filled with PP ranching rings.
Air is forced from the bottom of the tower by Centrifugal Blowers, while the water flows down through the packed bed of PP rings.
The carbonic acid present in the water splits up into Carbon dioxide gas and Water. This Carbon dioxide gas is stripped off and escapes from the top of the tower. The water free from carbonic acid is collected in the Degassed Water tank and is pumped to down-stream units for usage. In mixed-bed deionizers the cation-exchange and anion-exchange resins are commonly mixed in a single pressure vessel.
The thorough mixture of cation-exchangers and anion-exchangers in a single column makes a mixed-bed deionizer equivalent to a lengthy series of two-bed plants. The modular construction permits flexibility in the selection of cation and anion units to cater to different types of raw water.
The applications have it uses in food and beverages, pharmaceuticals and paper and pulp industry. As a result, the water quality obtained from a mixed-bed deionizer is appreciably higher than that produced by a two-bed plant. Language English German Italian Spanish. It consists of following: 1. Mixed Bed In mixed-bed deionizers the cation-exchange and anion-exchange resins are commonly mixed in a single pressure vessel.
Water Treatment. Enquiry Form.Kindly share with me. Regards, Yuvaraj. Hi Yuva. I can't understand your question I am probably misunderstanding you, but although you can use sodium chloride for removing water hardness the sodium replaces calcium and magnesiumyou can't regenerate dual bed cation and anionor mixed bed ion exchangers with sodium chloride. Good luck. Good morning sir, For cationic and anionic resin we regenerate with Sodium hydroxide and Hydrochloric acid.
My question is how much quantity of sodium hydroxide and hydrochloric acid is needed for regeneration of each resin. For example, in softening plant of liters resin we should regenerate 16 kg sodium chloride. For off-site regenerated cation and anion resins or co-currently regenerated systems, the strength is the same but the dosage is higher, typically about 6 pounds of chemical per cubic foot of resin. One other note about softeners.
Ion Exchange / DM plant calculations, p.2
The dosage required depends upon whether the softener is regenerated in a co-current or counter-current manner. Please tell me -- How to determine the concentration of acid or alkali as a regenerant of cation and anion resin respectively. Hi Sachin. Lyle Kirman's answer to Yuva Raj has been placed immediately before your question. If Lyle's response is not what you were looking for, please phrase your question in terms of what you have done and are trying to do, and write a few paragraphs describing it.
I can't tell from your abstract question if you are looking for an analysis method for acid and alkali, or for conversions from one scale to another, or if you are asking what is the standard concentration of acid and alkali to use for regeneration, or if someone has sold you regeneration chemicals that you are reluctant to use without testing, or if you are trying to judge the endpoint for the regeneration based on analysis of the remains or what I think I provided insufficient data, but still anyone know any way to calculate?
It is extremely difficult to get accurate pH measurements on high purity water. Resistivity is the best assurance that the pH is within a narrow range close to 7. Respected sir, I'm "jitu". I want to know about colloidal and reactive silica? You may consult your resin supplier a suitable flow rate.
Regards, David. It depends upon several factors. In residential applications, where there is a brief, but relatively high peak flow and long periods of no flow, rates of 40 BV per hour are common. This rate would not be suitable for a continuous flow. Dear sir, Our raw water parameters pH - 7- 7.
Hello Anand, Your IX resin supplier should be happy to do this for you. For the quantity of resin needed, you will also need to tell them the flow rate that you want to operate at. Hi Satish. That's a question that I hope one of our knowledgeable readers will address. But I have a question for you: Why are you interested in that approach?
What's the deal? Luck and Regards. Satish, If there is hardness in the water, then it will foul the anion resin and the system will not work.We have increased the output to m 3 per regeneration by increasing the run length to 26 hours instead of the design 20 hours. This is being done for one month.Demineralization Plant
The output water quality has not changed. Please let us know will there be any adverse effect by this prolonged run length on the resin. Also please tell us how to calculate the optimum output from a DM plant. Dear DEVU, By Doing the above you will not have any problem as you have already reduced the ionic load then you will not have any problem. Regarding the optimum OBR you can contact your supplier, as while designing the which resin he has taken we do not know.
To calculate the ionic load of water, first check the total dissolved solids, and then calculate resin proportionally. If your ionic load is less then the time of designthen you can take more water for demineralisation but you cannot change the rate of input or rate of output.
Because proper time should be given to exchange ions, for that you have to change the height of columnthen you can increase the feed rate with same quantity of resin if your ionic load is less then design.
Now your load is about 25 kgs then you can get double production with same resin with design feed rate. For that you cannot change the feed rate, but you can produce double water with same feed rate of design. Please provide several complete sentences, not a dependent clause :- Thanks. Please give your comment or suggestions for improving the OBR.
It will depend upon the resin exchange capacity.
What resin you are using for the ion exchange process? Outlet pH is coming down with MB's. Whether MB's can be bypassed or not. Please advise to get good results. Thank you.The SOP also covers preventive maintenance schedule and gives guideline for maintaining critical spares generally required for maintenance. The SOP specifies the responsibilities of staff for the various functions outlined here under.
DM Plant removes mineral salt by an ion-exchange process from the raw water. After demineralization water passes through the fine filtration and UV sterilizer so that the water meet all the specification of pharmaceutical for purified water 4.
It also helps to reduce the impurities like colour, taste etc. The Cation Exchange material, which exchanges Cations such as Calcium, Magnesium and Sodium for hydrogen ions to form the corresponding acids.
This process is reversed when the resin is regenerated by hydrochloric acid through column. The strongly basic Anion Exchanger will remove the acid formed by the cation exchange material and producing water, which is free from dissolved solids.
This process is reversed when the resin is regenerated by Caustic Soda solution Mix bed Exchange column of MSRL material contains Cation and Anion resins and thoroughly mixed with compressed air. When the water passes through Mixed Bed Column the traces of dissolved salt leaked out will be retained in the Mixed Bed Column. Conductivity meter is used to show the purity of dematerialized water. The conductivity is proportional to be the residual ionized solids in the water. Low conductivity indicates water of high purity.
UV as disinfections is used for removing microbial reduction. Ensure that the all valves are in operation. Check that all piping work is carried as per its piping drawing given in manufacturers manual. Ensure that there is no water leakage. Ensure that the DM plant feed water pump gives rated flow and pressure required for DM plant.
Test the water inlet quality. It should be as per specification given in design data.

There is a lot of great things in here, I just wish there were tables gathering all the types of plants based on where they are found for quick reference. It took me a bit to find it but it was well worth the wait. This is Ed Greenwood level thinking right here. Thank you for making the realms come alive that much more! Just finishing a campaign having my players traveling through Methmere in Unther.
Your book was excellent. Thanks, great fun for my players. Love the book I wonder why there is no mention of "Wolfsbane" here cures lycanthropy, it seems. Also, 31 pages, almost 40MB. This is my first purchase and I wonder if this is normal.
I absolutely love your guide, the plants and fungi are fantastic and the herbalism system works wonderfully! I was wondering if I could use some of the material from your guide in a compilation of fantasy plants I'm working on? I already purchased the PDF to look through and use in my own campaigns, but would it be okay to add to the compilation? I'd absolutely give you credit and mention that they can buy your guide to anyone I share it with.
