Module 2: Water Clarification

when we discharge produced water, do we need to comply to any regulation?

• Yes

• No

• Both

• Depends

The oil in water content in discharge water must follow:

• DOE regulations (500ppm) only

• DOE regulation (100ppm), Petronas (40ppm)

• Petronas (40ppm only)

• DOE regulation (40ppm), Petronas (100ppm)

HOW WATER CLARIFIER WORKS?

____________ is the process of encouraging small droplets of oil to merge or coalesce to form large droplets. __________is the process of agglomerating small droplets and solids into clusters.

• Separation, Sedimentation

• Oil, Water

• Coagulation, Flocculation

Water clarification products are applied to remove which of the following from produced water:

• Dispersed oil

• Silt and clay

• Emulsified oil

• Corrosion by-products

Other than using TD500 to analyse oil in water, which other method that can be use?

• Water Content by KF

• Extraction by APHA 5520B

• Acid Digestion

• Pour Point

In our lab, where does water clarification being implement?

• Water Scrubber

• WWTP

• Domestic Sewage

Common polymer type being widely used

• Latex Polymer

• Solution Polymer

• Solubility Polymer
