Lanlang TA301D (A100) is supplied in the fully regenerated form to be put in to servce immedately we recommend however that the resin be backwashed to prevent channeling or pressure loss.A backwash expansion of 35 to 50% would be adequate. When A-100 is tollowed by a strong base resin (e.g.A-400), all or a portion of the regenerant can be used to regenerate the weak base resin.We recommend that this procedure be reviewed with us so that we can determine whether enough caustic is avalable to completely regenerate A-100
