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 Denitrification 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% in accordance to the effluent parameter limit in the standard A Category 1 under the Environmental Quality Act 1974 by Department of Environment.
