Chlorine dose in water system depends on the type of water. If your
water source is undground, you can set your dose approximately 150 to
200 ppm(most probable) chlorine.It should be set on pretreatment of
water. If you use this water for drinking, you have to monitoring
microbiologically for bacterial count(<1000 cfu/ml), in that case dose
may be reduced. If you use this water for inlet of water treatment
plant(Purified water), microbial count should be within 100 cfu/ml.
That means you have to validate this dose accurately.
