PRIMARY AND SECONDARY STAGES
The effectiveness of the pre-treatment system is affected by the highly polluted wastewater streams from a palm oil mill which contain various suspended solid contents.
Secondary Wastewater Treatment pH Monitoring
For the execution of anaerobic treatment, the optimum temperature is 37° C. Hence, cool-ing process using cooling towers is needed before biological treatment because POME at this stage exists at a high temperature of 75 to 90°C. However, acidifying processes will occur as well, in which oil/grease is converted into fatty acids and consequently become short-chain organic acids via enzymatic reactions. Odour-generating substances are released at the same time which creates an unpleasant smell. Control of pH (at about 7-7.5) is important to avoid this problem.

FINAL EFFLUENT
Installing an ID-223 sensor in the final ponding system will continuously monitor the
discharged water and ensure treatment is running smoothly. A spill condition will be
detected and the operator notified, or the system can automatically stop the dis-
charge and contain the spill, allowing the operator time to take appropriate action.
Water Treatment Discharge Monitoring APPLICATION
• Above-ground oil storage tanks• Oil/water separators• Cooling water systems and trenches• Storm water run-off• Wastewater sewer systems
Electromagnetic Absorption
Technology
Advantages
of Leakwise system
Water absorbs much more microwave energy than hydrocarbon
High frequency Electromagnetic Energy is transmitted through air/water interface and received by antenna below water surface
Loading of antenna is proportional to the Hydrocarbon layer
www.centrionics.com
Continuous on-line monitoring with self-diagnostics
Certified for operation in hazardous area. The sensors are intrinsically safe.
Proven long-term reliability - Early detection of oil leaks or spills even if the sensor is coated with dirt or oil, or there area variations in water salinity, temper-ature, liquid level or liquid turbulence.
Easy installation and setup.
Low maintenance - No parts to replace. Operate essentially maintenance free over extended periods of time. No cleaning required after an oil spill
Versatility - Leakwise is available in several application - specific models, that can be easily installed in sumps, retaining tanks or other containments.
Thin oil layers detection, from 0.3 mm in all conditions.
Immediate detection upon oil contact with the sensor (Fully complies with 30 seconds FFM class 7745 standard)
Ability to operate even without water
Thickness measurement - Leakwise not only detects hydrocarbon sheens but can measure the build-up of hydrocarbon layers

Leakwise ID-223 Oil Sheen Sensor
PS-220 Analog Leakwise Controller
APPLICATION SOLUTIONS
The Leakwise ID-223 has three sub-models for different maximum water fluctuation capability:• ID-223/500 – up to 500 mm (19.7 in)• ID-223/2000 – up to 2,000 mm (6.6 ft.)• ID-223/2500 – up to 2,500 mm (8.2 ft.)
The PS-220 Analog Leakwise Controller is a power supply and signal processor that interfaces with a single (1) Leakwise ID-220 Series Sensor to report hydrocarbons spill/leak alerts, including layer build-up and thickness, to users via outputs interfaces for local or remote reporting.
The PS-220has a well proven reliability and is cost effective for a basic monitoringsystem. It can be AC or DC line powered.
APPLICATION SOLUTIONS FORFINAL EFFLUENT IN WATER TREATMENT
Why Is It Important To Detect Leaks (Early)
Value of organic carbon monitoringLeaks have significant cost and maintenance impact:
Fouling: contaminated steam, feed, condensate leads toequipment failure or higher maintenance costs.
Energy costs:loss of efficiency - more energy to achievesame heat transfer
Corrosion: organics form organic acids in steam cycles.

CONTENTSSterilisation Of Fresh Fruit Bunches (FFB)APPLICATION
Boiler feed-water is required to produce pressurized steam for sterilisation of loose palm fruit. Heat treatment destroys oil-splitting enzymes and arrests hydrolysis and autoxidation. Heat helps to solidify proteins in which the oil-bearing cells are microscopi-cally dispersed. The protein coagulation allows the oil-bearing cells to come together and flow more easily on pressure application. The moisture introduced by the steam acts chemi-cally to break down gums and resins.
Ideally, feedwater is supplied in a closed-loop system with stable and sustainable water quality. In reality, feedwater quality deteriorates:
Fluctuations in source water caused by seasons, storm eventsImpurities that bypass makeup treatment processContaminated return condensateExtractable and/or residuesExcessive dosing chemicals Biofilm growth
