WebOct 5, 2024 · Thus these resins regenerate with very little excess chemical. Typically 20% more than stoichiometric requirement. - A slow rinse cycle removes chemical from resin … WebThe regenerating solution flow rate is low enough (2–4 m 3 /h m 3 of resin) to allow the chemical to diffuse into the resin and to allow the largest impurity ions to migrate out of …

Each engineer had their own way to carry out in their calculation. Before starting the design ideally you need to know some basic information: 1. Maximum / Average / Minimum flow rate and roughly how many hours per day the maximum flow rate is required (m3/h). 2. cliff richard congratulations mp3 download

WebOct 30, 2024 · How do you regenerate resin? Caustic soda, or sodium hydroxide (NaOH), is used to regenerate the anion resin. A concentration of 4% is applied at a flow rate between 0.25 and 0.5 gpm per cubic foot. A contact time of 45 minutes minimum, 60 minutes preferred, is required.Apr 7, 2006 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 regenerant must be displaced with water from the resin bed until only traces of the chemical are left. This displacement rinse is done at a low flow rate, the same as the regeneration flow rate. Final fast rinse. Finally, the resin bed is submitted to a fast rinse at service flow rate to remove the last traces of regenerant. boat 420
