2.1. MECHANICAL EQUIPMENT PRE-COMMISSIONING
1. FLUSHING and CLEANING Flush inside of pipe with water for few minutes until effluent is clear. Open valves slowly to flush all dirt, debris, excess sealant and scale. Clean inner surface of filters and exchanger vessels.
2. CHEMICAL PREPARATION
Pre-caution:1. Person who prepares harmful or dusty chemicals should wear suitable protective equipment.2. Training and advises shall be given to workers in order to understand the cause of harm that
would occur while working with chemicals. Method of prevention and measures to be used
in tending to the accident should be explained clearly to the workers.3. Provide water for cleaning within the place of preparation.4. Consider which chemical uses service water for dilution, and which one uses filtered water.
Preparation:1. Alum is prepared as per the following procedure;
1.1. Coagulation dissolving tank (10GBN10BB001) Fill the tank with filtered water until half of required level H Load 255.5 kg/day of alum (flake) into the tank via electrical hoist manually Further fill the tank with filtered water until required level H = 1,600 mm Start Agitator (10GBN10AM001) for 1 hour or until alum is dissolved
1.2. Coagulation Feed Tank (10GBN10BB002)

4. RESIN LOADING
Precautions:1. It is important to cross check the resin volumes loaded into each vessel. Record the actual
resin level in delivery form after backwashing and settling.2. A careful measurement of the freeboard (in delivery form) should be made, reported, and
checked with the original design. If necessary, corrective action should be undertaken toeither load resin or download some.
3. Whenever possible, avoid the direct contact of the active resin with the nozzles.4. Resins to be loaded are listed in Table 3.
Procedure:1. Remove the top head of the vessel and top nozzle plate.2. Fill 1/3 of the vessel with water. Loading resin into water ensures that any air and dirt are
floated off the resin and come out to the surface of the water. This will allow the resin bed tosit evenly & homogeneously throughout the height of column.
3. Load the active resin as per the specified quantity.4. Load inert resin as per the specified quantity.5. Close the top head of the vessel.

5. OIL INTERCEPTOR CHECK
5.1. Make sure that all internal equipments are in place and no tools or other loose itemsare left in the interceptor.
5.2. With the automatic closure device in oil chamber feed, fill all interceptor compartmentswith clear water to the outlet level.
5.3. Check that the stainless steel automatic device follows the level of the water.

6. TRIAL RUN
General:The following equipments shall undergo trial run to demonstrate that they can operate safelyand satisfactorily under the required operating conditions.
1. Clarifier tank A/B (RWTS)2. Gravity filter A/B
Manual backwash Auto backwash
3. Demin Train A A/C filter A (Demin) soaking Manual regeneration Auto regeneration
4. Demin Train B
A/C filter B (Demin) soaking Manual regeneration Auto regeneration
5. Clarifier tank (WWTP)6. Sludge receiver tank7. A/C filter (WWTP)
Soaking Manual backwash Auto backwash
Manual Backwash:It is very essential to perform manual backwash operation on each of Auto Gravity and Carbon
Filters before operating to auto-mode so that foreign particle present in the media duringdelivery are washed out from the vessel. In this operation, preliminary adjustments of manual &actuator-operated valves, instrument set points, flowrate, etc. should also be done.
Auto Backwash:When all necessary adjustments are completed, it is important to perform a trial run in automode for one cycle before performing the commissioning proper in order to counter-check theadjustments made. Final adjustments shall be done after one cycle, when necessary. Operationis the same as the commissioning operation (Refer to the section COMMISSIONING).
Activated Carbon Soaking:Activated carbon is filled with internal pores where air may exist. Before backwashing, bed must
be set in completely submerged condition to allow carbon pores to fill with water. Otherwise, thereduced density of carbon due to air in the pores may result in excessive backwash losses.
Manual Regeneration:It is very essential to first perform manual regeneration and backwashing before setting to auto-mode so that preliminary adjustments in the plant can be done; such as manual and actuator-operated valves adjustment, instruments set points, flowrate adjustment, chemical dosingadjustment, etc. This is also essential for the resin in order to wash away foreign particlespresent during delivery. This step shall prepare the correct ionic exchanging capacity of resin.Manual regeneration literally means regeneration of each step of every unit in manual operation.

Automatic Regeneration:When all necessary adjustments and preparations are completed, it is important to perform a
trial run in auto mode for one cycle before performing the commissioning proper in order tocounter-check the adjustments made. Final adjustments shall be made after one cycle, whennecessary. Operation is the same as the commissioning operation (Refer to the sectionCOMMISSIONING).
Initial Resin Regeneration:Irrespective of the form delivered, the resin bed should receive at least a double amount ofregenerant compared to the design level. This means a double-injection-time only, whiledisplacement and rinse should be performed as per original design.
First Run:Expected high water quality will be achieved only after final rinsing, after Mixed Bed Exchanger
in the case of Demineralizer, but provided that endpoint is monitored correctly and the plant isnot overrun.

3. COMMISSIONING
GKC and Lilama Staffs shall together perform the Commissioning Work, or if necessary, withEVN Staff also. GKC Staff shall explain the operation of the Water Treatment Plant and trainLilama and EVN Staffs, as well.
3.1. PERFORMANCE TEST
General:Performance Test shall be done by running the plant for two cycles. Demineralized andCondensate water quality shall be checked with conductivity meters. Commissioning resultsshall be recorded in the Commissioning Result form. Period of commissioning shall be
referred to the Table below;
Table: Commissioning PeriodITEMS

Gravity Filter 105 m3/hr x 2 2 x 2 x 2 x
Carbon Filter (Potable) 90 m3/day x 2 2 x 2 x 2 x
Carbon Filter (Demin) 41 m3/hr x 2 2 x 2 x 2 x
Demineralizer Trains 41 m3/hr x 2 2 x 2 x 2 xCarbon Filter (WWTP) 70 m3/hr x 2 2 x 2 x 2 x
Procedure:1. Run the plant for 24 hours per day for 2 days.2. Take data of influent flowrates for Clarifier Tank, Gravity Filter, Carbon Filter, Cation
Exchanger, Anion Exchanger, and Mixed Bed Exchanger every hour.3. Take data of pressures for Gravity Filter, Carbon Filters, Cation Exchanger, Anion
Exchanger, and Mixed Bed Exchanger every hour.4. Take data of conductivity for Anion Exchanger and Mixed Bed Exchanger every hour.5. Take data of pH in Clarifier Tank every hour.6. Take sampling at sampling cocks of Gravity Filter, Carbon Filters, Anion Exchanger, and
Mixed Bed Exchanger every 4 hours for analysis. GKC and Lilama will take sampling atthe same time and perform internal analysis for comparison purposes.
7. Take note of the running time of first on-line Demineralizer train following switched-over ofthe standby train.
8. Take note of the duration of regeneration period in every regeneration cycle.
