Authority/Agency that controls the quality of water in Malaysia?
Kettha (Kementerian Teknologi Hijau dan Air)
Petra (Kementerian Peralihan Tenaga dan Transformasi Air)
MCMC (Suruhanjaya Komunikasi dan Multimedia Malaysia)
Regulator for water distribution?
Syarikat Bekalan Air (Syabas)
Jabatan Bekalan Air Malaysia (JBA)
Suruhanjaya Perkhidmatan Air Negara (SPAN)
Basic principle used for water treatment are:
Storage - Sedimentation - Filtration
Storage - Filtration - Disinfection
Storage - Disinfection - Filtration
What is the process happen during disinfection?
Screening - Aeration - Flocculation
Rapid sand filter - pH balance - Chorination
Flouridation - Chlorination - pH balance
During the process of storage for clarification of water treatment, SCREENING is;
the process removing suspended matter from water
the process of sendimentation
the process of aeration
Flocculation is the process of...
aluminums will act as thickening agent that allows small particles such as clay, colloid, gel and emulsion to combine and form larger particles (flocculants).
fine focculants combined to form larger and heavier flocculants so as it settle easily during settling process
removing suspended solid from water. Time required for the solid to settle will depend on the size of the flocculants - longer time required for smaller flocculants
Balancing tank is...
Supplies water to the distribution areas such as residential or industrials areas
Store large quantity of water with min. 450 m³ and maximum 9000 m³ respectively.
Store treated water at treatment plant before it is channeled and distributed to consumers through balance and services tanks
Surface reservoir is also call as...
Ground reservoir
Overhead tank
Circular tank
Methods of distribution system;
Gravity distribution, pump system, combination
gravity and pump system
gravity system
Advantage of Gravity water tank system:
reliable water supply from higer level to lower level
control the pressure and speed of water
water supply interrupted when there is interruption in the electricity supply
