  • SCOPE:

This SOP is applicable for the Operation of Water Treatment Plant

  •  RESPONSIBILITY:

      Assistant Engineer/Above shall be responsible for implementation and compliance of the SOP.

  • ACCOUNTABILITY:

Manager-Engineering / Manager-Production / Head-QA shall be accountable for implementation and compliance the procedure mentioned in this SOP.

  • ATTACHMENT:

Not Applicable

  • PROCEDURE

     PRE START-UP:                                                                                                                 

  •   Ensure that electrical supply is available at the control panel
  • All the feed pumps are free without any obstacles.
  • All the valves are in proper position for operation.
  • Sand filter, Activated Carbon Filter, Multi grade filter should be backwashed before operation
  • Check adequate quantities of all required chemicals in stock.

6.1.6   Check for any leakages anywhere in the systems and take adequate precautions.

6.2       OPERATION PROCEDURE FOR PLANT I:

6.2.1    Check the water level in Under Ground Water tank .Start the raw water feed pump by pushing up

the MCB and fill raw water in storage tanks of water plant.

6.2.2    Start the water feed pump of Sand filter -1 and dosing of Sodium Hypo Chlorite from ON/OFF switch..Store this water in chlorinated water tank.

6.2.3   Open the outlet valve of chlorinated water tank and Switch ON the main panel of RO system .Start the water feed pump of sand filter -2 and activated carbon filter.

6.2.4   Start dosing of SMBS for neutralization of free chlorine in water. SMBS treated water will pass

through the Sand Filter-2 and Activated carbon filter

6.2.5   After treatment from sand filter -2 and Activated Carbon Filter, Start dosing pump of Anti Scalant

from main panel  to prevent scale formation in RO.

6.2.6   Switch ON the high pressure pump from main panel. After pumping from high pressure pump water

will pass through RO membranes. RO rejected water will be stored in Waste Water tank and RO pass

water be stored in RO water tank passing through UV lamps.

6.2.7   Switch ON the RO Water feed pump to lift water from RO water storage tank to Purified water tank

via Cation, Anion and mixing  bed .

6.2.8 Open the valve of purified water tank to use at user point.

6.2.9 Operator will update the following in the formats of their respective SOP”s

  • Dosing of Sodium Hypo Chlorite ,
  • Dosing of Sodium Meta Bisulphite,
  • Dosing of Anti Scalant,
  • Backwash of Sand Filter, Carbon Filter and Multi Grade Filter.
  • Cleaning and Replacement of Micron and Vent Filters.
  • Cation , Anion and Mix Bed Charging/Regeneration.
  • OPERATION PROCEDURE FOR PLANT II:
  •   Check the water level in Under Ground Water tank .Start the raw water feed pump by pushing up the MCB and fill raw water in storage tanks of water plant.
  •  Start the main panel of Ultra Filtration System.Ultra Filtration System will operate in Auto mode.Ultra Filtration System will be backwashed itself after 12 hours and come to service.
  •   Water from Ultra Filtration System enters in Ultra Filtered Tank.
  •  Switch ON the main panel of RO system.RO system will operate in Auto Mode. Start the water feed

pump of Multi Grade Filter and activated carbon filter.

  •    Start dosing of Sodium Hypo Chlorite ,SMBS and Anti Scalant
  •  Switch ON the high pressure pump from main panel. After pumping from high pressure pump water

will pass through RO membranes. RO rejected water will be stored in Waste Water tank and RO pass

water be stored in RO water tank passing through UV lamps.

  •    Switch ON the RO Water feed pump to lift water from RO water storage tank to Purified water tank via  Cation, Anion and mixing  bed .
  • Open  the valve of purified water tank to use at user point.
  • Operator will update the following in the formats of their respective SOP”s
  • Dosing of Sodium Hypo Chlorite ,
  • Dosing of Sodium Meta Bisulphite,
  • Dosing of Anti Scalant,
  • Backwash of Sand Filter, Carbon Filter and Multi Grade Filter.
  • Cleaning and Replacement of Micron and Vent Filters.
  • Cation , Anion and Mix Bed Charging/Regeneration.
