sop for Operation of Soft Water Plant
1.0 OBJECTIVE :
1.1 To lay down a procedure for operation of Soft water plant
2.0. SCOPE :
2.1 This procedure is applicable to operation of Soft Water plant
3.0. RESPONSIBILITY :
3.1 Operator Engineering Department shall be responsible for operation of Soft water Plant
3.2 Officer/Executive Engineering Department shall be responsible for to verify the proper operation of Soft water Plant
4.0. ACCOUNTABILITY :
4.1 Head Engineering Department shall be accountable for compliance of SOP.
5.0. PROCEDURE :
5.1 Operation Procedure of Soft Water Plant
5.1.1 Before starting the plant ensure backwash and rinse activity of MGF is done.
5.1.2 Keep Multiport Valve for backwash direction position (water flow down to up position) in MGF (Multi Grade Filter) for10 minute and drain the backwash water.
5.1.3 After backwash keep multiport valve position in rinse direction in MGF
(Multi Grade Filter ) for 10 min and drain the rinse water.
5.1.4 Start raw water pump, Water flows down to up position in Softener, Maintain flow 6000-7000LPH and water hardness less than 5 PPM
5.1.5 Collect Water in Soft Water Tank
5.1.6 Regenerate Softner after 100KL or if hardness more than 5PPM.
5.2 REGENERATION PROCESS
5.2.1 Make salt solution 35 Kgs in 100 Ltr Water in HDPE Tank and ensure that the solution shall be in clean condition.
5.2.2 Mix solution with compressed air/Stirrer. Keep Valve position in regeneration mode in Softner and connect solution tank with pipe and start soft water pump
5.2.3 Salt solution injection start from up to down direction, Drain the solution after 10 min rinse process.
5.3 METHOD OF SOFT WATER HARDNESS TEST
5.3.1 Take 50ml Soft Water and mix 10 drop solution ‘A’ after shaking solution.
5.3.2 Add solution ‘B’ few drops, If Water colour comes Pink, add solution ‘C’ drop by drop with counting. If colour change from Pink to light blue by one drop means 1PPM Water, If by 2 drop colour gets change, means 2PPM hardness of Water. Take reading dally basis.
