WebSep 17, 2024 · Besides, the resin regeneration rate of MFEDI is 11.8%, which is relatively low (Hu et al. 2015b). If the regeneration rate is to be further increased, the regeneration … Webthe resin bed. Properly compensating backwash flow rates vs. water temperature will help prevent these problems from occurring. Consult specific resin manufacturers' backwash expansion curves to find the proper flow rate at different temperatures. • Regeneration cycle. Strong-base anion resins operated in the hydroxide form are best regenerated

WebThis calculator helps you with the design of a ion exchange installation. The calculator is based on the following process: The calculations are made using theoretical equations. As a consequence this calculator ONLY gives you an indication about the different parameters that are necessary to design an Ion Exchange water treatment installation. WebFor the record, the use of “weak” resins in superimposed beds or separated beds permits rates of between 105 and 115% of stoichiometry to be reached for resin regeneration. “Strong” resins require much higher regeneration rates. Due to its simplicity, the UFD is perfectly adapted to the practical applications of superimposed beds.
WebFeb 1, 2024 · Furthermore, for this resin weak-base anionic resin, regeneration efficiencies within the same range (aprox. 98%) were confirmed upon both 2.5–5 L h −1 flow rates, thus it may be similarly efficient to operate the regeneration process at this higher flow rate to attain minor regeneration cycle times. Webcalculate the design by hand using resin manufacturers data. Each engineer had their own way to carry out in their calculation. Before starting the design ideally you need to know …
Web• Effective counterflow regeneration requires that the resin bed is not disturbed during regeneration. • Upflow of regenerants would tend to fluidise and mix the bed • The answer is to hold the bed in place by: – Air hold down – Water hold down – Split flow (Co-Counter flow regeneration) – Packed Bed Resin regeneration © WebThe regeneration is concentration dependent and not stoichiometric. It requires the salt concentration inside a resin bead to be at about 3+% NaCl. To achieve this, 10% NaCl solution is required. The regeneration flow direction is down-flow at …
