Lewatit® MonoPlus MK 51 is a styrene-based, monodispersed, macroporous weak base anion exchanger with polyhydroxy groups showing a very high selectivity for the removal of boric acid or borates from water. The high selectivity of borate to the resin allows a separation of boric acid from water and aqueous electrolyte solutions also a high salt concentration. Lewatit MonoPlus MK 51 can especially be used for:- the removal of boron from waste water or contaminated ground water
- the removal of boron from RO permeate in purpose to produce water for irrigation
- the removal of boron traces in the production of ultrapure water or chemicals
- removal of boron from high concentrated magnesium chloride solution
- adsorption of oxoanions of W, Mo, V Ge, As, Sb, from processes streams
The resin is appropriately exhausted at a specific flow rate of 10…20 BV/h. The regeneration can be done with hydrochloric or sulfuric acid. To reach high capacity levels it is recommended to make a two stage regeneration using a sodium hydroxide solution for the second treatment (conditioning).Information provided by Lanxess. |
