A water softener has 0.1 m3 of ion-exchange resin with an exchange capacity of 100 kg/m3 . The consumption rate is 5,000 L of water per day. If the water contains 270.0 mg/L of hardness as CaCO3 and it is desired to soften it to 85 mg/L asCaCO3, how much should be bypassed? What is the time between regeneration cycles?
