The vast extent of water bodies and water supply systems renders them susceptible to accidental or intentional contamination. The challenge of maintaining a safe and sufficient water supply system to meet the needs of a growing population and enable economic growth is compounded in nation such as Singapore which has only limited natural sources of fresh water, making effective monitoring of water supply infrastructure a critical national need. Water quality sensing has become increasingly important as water scarcity, natural and anthropogenic threats, and demand collide.
The Water Lab of Ecosen Solutions can help to safeguard:
(1) Water catchment
(2) Water drainage and waterways
(3) Detect industrial discharge
(4) Intake monitoring
(5) Aquaculture farm
(6) Recreational water bodies
(7) Monitor oil and gas leakage
(8) Against harmful substances in seawaters
(9) Toxicity and chemical testing
(10) Ballast water monitoring
(11) Environmental and ecosystem research
Examples of Detectable Substances
Its applications are varied and the typical optical detection include the following:
Examples of analytes and substances that have been quantified with the Water Lab includes:
(a) Water Chemistry: CDOM, Crude Oil, Diesel, Fluorescein, Humic, Naphthalene, Oil Dispersant, O-Xylene, Palm Oil, Phenol, Pyrene, Rhodamine B and 6G, Toluene, Total Organic Carbon, Styrene.
(b) Biological Pigments (in live algae): Chlorophyll a and b, Fucoxanthin, Phycocyanin, Phycoerythrin.
(c) Turbidity, Total Suspended Solids.
(d) Water Physical Properties: (1) Temperature, (2) PH, (3) Oxidation Reduction Potential, (4) Dissolved Oxygen, and (5) Conductivity/Salinity/Total Dissolved Solids of the PhyWL sensor are available to be coupled and incorporated into the PWL, AWL, and VocWL sensor.
This makes comprehensive ‘lab-like’ sensing possible.
