FLOW CHART:

In--- Online Lime Doser --- Aeration Tank with rotary type air blower --- Pump---Iron Filter ---- Softener—Treated Water Tank

UNITS OF THE SYSTEM PROPOSED:

Sr No Item Specification Qty Amount(Rs.)
1 Online Lime Doser with storage tank 01
2 Aeration tank RCC Tank 01
3 Rotary type air blower aeration grid in aeration tank 01
4 Main Water pump from aeration tank to Iron Filter 1W+1S
5 Pipe and Fittings LOT
6 Iron removal filter 80.00 CuM / Hr 01
7 Water Softener, 1000 CuM / Regn. @ 180 ppm rwh, 80 CuM / Hr 01
8 Treated Water Tank RCC Tank 01 OPTIONAL

NOTE:

The iron removal depends upon dissolved oxygen present in water. Please make sure that the raw water has at least 0.4 ppm dissolved oxygen. Failing which, an aeration system will be added to the Iron removal plant as mentioned in item no 2 & 3 .

So, testing of water sample is the first step.
