• MAKE IT SAFE FIRST by flushing out any chemical residues from the pumps and pipelines and isolating the equipment. • When in doubt ASK. Consult this manual, a trained operator or Aquatic Engineering Australia Pty Limited. • Always follow correct LOTO procedure BEFORE you dismantle any electrical equipment. -

Page 9: Installation
Operation and Maintenance Manual 4.2 Installation The Trident T4R lamella must be placed on a suitably engineered and level footing. The maximum allowable fall in any direction of the installed lamella is 1 in 100. The lamella must be levelled for operation. Failure to ensure a level installation will significantly impact the effectiveness of the lamella to remove solids via settling. -

Reinstall the locking bolt and pin on the ladder to prevent the handrail from collapsing 4.5 Safety Shower/Eyewash This unit should be connected to an uninterrupted source of potable water, no less than 25mm with a minimum flowing pressure of 138KPa and a and a maximum static pressure of 860 KPa The Trident is fitted with a combination safety shower and eyewash unit. -
Page 13: Process Description
Operation and Maintenance Manual 5 Process Description The pre & post treatment around the lamella will vary dependent on the overall process into which the lamella is placed, however the operation of the lamella settling system is described in the following. Feed The lamella is required to be fed from an upstream source (usually a feed tank), via a gravity feed, or more commonly, a pump. -
Page 14: Lamella Chamber
Operation and Maintenance Manual The tank is fitted with a slow speed agitator, for mixing in the dosed flocculant solution into the feed. The coagulant (added into the feed pipe) initially reacts with solid particles in the water. Flocculant is then added in the reaction tank, which causes the solid particles to clump together (to flocculate), increasing their mass, which allows them to settle out of the flow stream. -
Page 15: Discharge
Operation and Maintenance Manual through the plate packs will not be even across the full area of the lamella, and short circuiting of flow will occur. Short circuiting increases the velocity of the flow stream which prevents the solid particles from settling out of the process water. -
Page 16: Sludge Removal
If the discharge water is out of specification – either the pH is too high or low, or the turbidity is too high – the discharge valve is closed, and the off-spec valve opened. Discharge criteria are set by Aquatic Engineering, based on information provided and in consultation with the hirer. - Page 17 Operation and Maintenance Manual As with the incline on the plates, the incline of the hoppers is 55-60 , which will allow most solids to slide down, however a sticky build-up can accumulate dependent on the sludge type, and so routine drain & clean practices may be required.

Page 21: Admin Settings
Operation and Maintenance Manual Do not adjust operational settings without first consulting AEA, and understanding the potential impacts of the change to the operation of the system. 6.1.5 Admin Settings The Admin Settings are inputs that will be set during commissioning. These values will be determined in consultation with the site, to determine the correct setting. -
Page 22: Setup And Commissioning
If feed water is available, wet testing will also be completed at the time. 6.3 Startup When starting up the Trident T4R after an idle period, while it has remained full of process fluid: 1. Ensure the pH probes have remained immersed; if they have been exposed to the air and dried out, it is possible they will require recalibration, or replacement. -
Page 23: Ph Control
Operation and Maintenance Manual Adjusting chemical usage is important to optimise the usage and reduce costs. 6.4.1 pH control the pH setpoint that the lamella is dosing to achieve can be set by the operator. The dose rate is automatically varied to achieve the target setpoint in the reaction tank. The pH correction dosing is controlled by a PID loop. -
Page 24: Lamella Desludging And Cleaning
Operation and Maintenance Manual 6.6 Lamella desludging and cleaning As solids settle out of the flow stream, they will build up in the cone of the lamella. There is a maximum amount of sludge that can be stored in the cone; once this volume is reached, solids will remain in the flow, and be discharged into the trough, increasing the turbidity at the outlet of the lamella. -
Page 25: Shutdown
Operation and Maintenance Manual Batches can be topped up by adding the correct proportion of flocculant concentrate to additional water requirements. 6.8 Shutdown When placing the lamella in standby, with intention to reactivate it: 1. Remove any sludge that may have accumulated in the reaction tank and settling tank 2. - Page 26 Operation and Maintenance Manual 4. Remove any sludge that may have accumulated in the reaction tank and settling tank 5. Using clean water, wash down all internal surfaces of the lamella 6. Drain the lamella, including the feed pipe. Open any manual drain valves on the lamella unit, including reaction tank drain valve and the discharge box drain valve 7.

Page 27: Maintenance
Operation and Maintenance Manual 7 Maintenance The frequency of maintenance on the Trident T4R Lamella will depend on the volume of water processed through the unit and, more importantly, the nature of the sludge/water that is being processed. The heavier and “stickier” the sludge load on the T4R, the more frequent cleaning will be required to prevent solids build-up on the inclined surfaces in the plates and hoppers. -
Page 28: Daily Checks
Operation and Maintenance Manual 7.1 Daily Checks Operator checks should be made at regular intervals during the day covering the following: Lamella and system Visually inspect lamella for damage Confirm power supply to lamella Confirm HMI is active Confirm power to chemical dosing pumps and floc mixer Feed Check upstream source for debris and solids. - Page 29 Operation and Maintenance Manual Routine Cleaning Clean Mixer Tank pH probe • With a soft cloth, wipe any residue off the probe tip. Take care not to apply pressure to the probe lense, only to remove any build up that may be on it. Clean Discharge Tank pH probe •...
- Page 30 Operation and Maintenance Manual • Run the sludge pump, until the discharge runs clear. • For optimal use, this process should frequently. The required frequency will be determined by the volume of sludge generated by the system, which is affected by feed water quality and quantity. Revision: 1 Uncontrolled when printed 30 of 34...
