7.0 M A I N T E N A N C E 7.1 SLUDGE PUMP OUT If the accumulated sludge at the bottom of the Treatment Tank is not removed, it will spill over into the Contact tank. In general terms, if the water in the sight glass turns from clear to grey or brown, a pumpout is required to keep the effluent quality above that required by IMCO standards. If it can be anticipated, that the ship will go to restricted waters, a sludge pump out shall be performed a few days before, in open (unrestricted discharge) waters, to ensure full operational time available without need of de-sludging. The procedure outlined below is recommended if the system is to consistently produce a clear effluent. The frequence of pumpout is determined by operating history and the owner's requirements. The time period specified below is average and based on the system operating at 100 % of rated capacity. 7.2 PUMPOUT PROCEDURE 1. Bypass sewage system or close sewage inlet valve. 2. Turn Discharge Pump off. 3. Close Disinfecting tank discharge valve V3. 5. Open the Pre-Treatment Tank valve V1 or Treatment Tank valve V2 6. Start discharge pump(s) manually (if provided) and drain or pump contents overboard, if outside of regulated waters, or into a suitable receiver for disposal. 7. Turn discharge pump(s) off when tanks are empty. DO NOT RUN PUMP(S) DRY. 8. Close the Pre-Treatment Tank valve V1 or Treatment Tank valve V2 9. Refill the Treatment Tank with water immediately after pumpout to maintain the bacteria and start up following procedure under „START UP“. DO NOT ALLOW SYSTEM TO REFILL WITH SEWAGE WITHOUT FIRST FILLING WITH WATER. For highest quality, drain Pre-Treatment Tank and Treatment Tank at 3 month intervals maximum.
