3. FILTER MEDIA LOADING Precautions: 1. Open manholes and check that inner equipment has no damage. 2. Confirm leakage in nozzle and sight glass by filling water into the vessel and check leakage. If no leaks were found, perform cleaning and flushing of vessel. 3. Confirm that there is no undesirable matter in the vessel. 4. Confirm the size and quantity of filter media. 5. Arrange and distinguish each kind of filter media. Procedure: 1. Care shall be taken to load media into the filter. Avoid direct pouring of media from the top manhole as inner paint could be severely damaged. 2. After each layer of media is loaded, the top surface shall be spread evenly and smoothly by forking or any other means as to prevent leading through of media. After spreading, check elevation. 3. Type of filter media top layer shall depend on media classification. Quantity of media shall conform to the spec. 4. After loading, inspect inside of vessel. Take out foreign matter and contaminants. Properly seal the top manhole. 5. Backwashing of media shall be carried out to remove any floating defective media. 6. Media to be loaded are listed in Table 2. Pre-Com and Commissioning Manual

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 to either 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 to sit 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. Table 3: List of Resin: NO VESSEL TO BE LOADED 1 Cation Exchanger A/B

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

6. TRIAL RUN General: The following equipments shall undergo trial run to demonstrate that they can operate safely and 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 tank 7. 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 during delivery 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 auto mode for one cycle before performing the commissioning proper in order to counter-check the adjustments made. Final adjustments shall be done after one cycle, when necessary. Operation is 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, the reduced 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 automode so that preliminary adjustments in the plant can be done; such as manual and actuatoroperated valves adjustment, instruments set points, flowrate adjustment, chemical dosing adjustment, etc. This is also essential for the resin in order to wash away foreign particles present 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 to counter-check the adjustments made. Final adjustments shall be made after one cycle, when necessary. Operation is the same as the commissioning operation (Refer to the section COMMISSIONING). Initial Resin Regeneration: Irrespective of the form delivered, the resin bed should receive at least a double amount of regenerant compared to the design level. This means a double-injection-time only, while displacement 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 is not overrun.
