Question

Example 9.36. Design a Zeolite-Softener for an industrial concern, using the
following data :
(i) Qty. of soft water required per hour = 25,000 litres
(ii) Hardness present in raw water as CaCO,= 400 ppm.
(iii) Hardness to be obtained in the treated supplies = 50 ppm.
(iv) Ion exchange capacity of the zeolite = 10 kg of hardness per cu. m. of zeolite
(v) Salt required for regeneration of exhausted zeolite = 50 kg per cu. m. of zeolite
Also assume that the industry works for 2 shifts of 8 hours each, per day
Make suitable assumptions where needed, if not given.
