Respected sir,

We are from Visakhapatnam, and we do all kinds of water treatment works. We design borewell water treatment for utility purposes only and we want to establish a filtration system at a low budget. What treatment method can be used to remove chlorides, CL is 2240 ppm, hardness at 2380 ppm and Nitrate as NO3 at 72.6 ppm from the water? This is bore water and treatment is needed for utility purpose only.

Per day requirement is 75000 liters and filtration system running hours is 4 hours.

Could you kindly recommend a good design for us?

Thank you.
