Wastewater treatment refers to the process of converting the wastewater into bilge water that could be discharged back into the environment so that it does not get wasted. Wastewater treatment Malaysia and other parts of the world are popularizing themselves and the same are urging people to save and conserve water.

Water treatment system of Malaysia has been a successful idea throughout the country and the government today is focusing more on the wastewater treatment in Malaysia so that the waste water can be reused and hence conserved. Two wastewater treatment plants are considered to be used in the management of wastewater namely, chemical treatment plant and biological wastewater treatment plant. The latter makes the use of biological matter as well as bacteria to break down the waste matter, whereas the former plants make the use of chemical reactions as well as other physical processes to treat the same.

Following is the step by step process involved in the wastewater treatment in Malaysia.

1. 1.      Wastewater collection:

This is the first step where the collection systems are put in the place by home owners or municipal administration. The water is collected and directed in a treatment plant by the way of an underground drainage system.

1. 2.      Odor control:

Odor control forms an integral part of the wastewater treatment in Malaysia. In order to make sure that the areas are free from smell, the process of odor treatment are started at the treatment plant.

1. 3.      Screening:

Screening involves the removal of all the large objects like diapers, nappies, rags, broken bottles, etc. so that these objects do not intrude with the functioning of the machines.

1. 4.      Primary treatment:

This process is all about the separation of macrobiotic solid matter from the wastewater and the same is done by the way of pouring the wastewater into bigger tasks so that the solid matter settles at the surface of the tanks.

1. 5.      Secondary treatment:

The secondary treatment includes the addition of seed sludge into the wastewater to make sure that is broken down. Air is pumped into the aeration tanks that mixes wastewater with the seed sludge. The wastewater is made pass through the larger tanks for 3-6 hours.

1. 6.      Bio-solids handlings:

The solid matter which settles out post the both stages of treatment is then directed towards the digesters. These digesters are heated at a room temperature. The wastes are treated for a month where they undergo the process of anaerobic digestion.

1. 7.      Tertiary treatment:

This stage is very similar to the one which is used by drinking water treatment plants that clean the raw water for drinking purposes. The stage removes up to 99 percent of impurities from the wastewater. Thus, the water so produced is effluent water which is close to the drinking water quality.

1. 8.      Disinfection:

The water still comprises of some organisms which may cause diseases when drunk. Thus, the process of disinfection is carried out for 20-25 minutes to disinfect the water.

1. 9.      Sludge treatment:

The sludge so produced and collected in the two process is then put into thickening tanks that permits it to settle down and later separates in from the water. The remaining water is collected and taken back to the aeration tanks for concerned treatment.
