Sewage Treatment Process

Langat Centralised Sewage Treatment Plant will contribute to the cleaning of Langat River by utilizing the Deep Aeration method with Step-Feed Multi Stage De-Nitrification Process

The wastewater processing will be operated underground, utilising a combination of Step-Feed Two Stage Denitrification Process and Deep Aeration Tanks. By using this technology, the Langat Centralised Sewage Treatment Plant can improve the achievement of low levels of ammonia and nitrogen removal ratio up to 80% according to the effluent parameter limits in the standard A category under the Malaysian Sewerage Industry Guidelines.
