Big­gest un­der­ground treat­ment plant in re­gion

Plant, where Pan­tai 1 was com­pleted in 2008 with a smaller ca­pac­ity.

“For Pan­tai 2, it is lo­cated un­der­ground and utilises the lat­est tech­nol­ogy in sewage treat­ment, with the abil­ity to serve up to 1.4 PE (pop­u­la­tion equiv­a­lent), pro­vided it is run with max­i­mum op­ti­mi­sa­tion,” he told the New Straits Times in an ex­clu­sive in­ter­view dur­ing the launch of the Pan­tai 2 Sewage Treat­ment Plant here yes­ter­day.

Zaini stressed that Pan­tai 2 was spe­cial be­cause, not only was it the big­gest sewage treat­ment plant in Malaysia, it was also the big­gest un­der­ground sewage treat­ment plant in the re­gion and the first in­te­grated one .

“The plant’s sewage treat­ment pro­cesses oc­cur be­low ground while the gas fa­cil­i­ties op­er­ate above ground.

“These gas fa­cil­i­ties are able to gen­er­ate roughly RM2 mil­lion to RM3 mil­lion worth of gas, mak­ing up the plant’s 30 to 40 per cent self-cons um p t i o n .”

This gas and sewage treat­ment in­te­grated func­tion was unique to Pan­tai 2, Zaini ex­plained, and it was an im­por­tant el­e­ment to have.

In ad­di­tion, Pan­tai 2 also in­cludes the first com­plete or­ganic ni­tro­gen and phos­pho­rus re­moval from the waste that is re­ceived into the plant.

“Other plants only have the ni­tro­gen re­moval func­tion, but re­mov­ing phos­pho­rus is also im­por­tant be­cause it is a source of nu­tri­ents that en­cour­age or­gan­isms like plants to grow abun­dantly in ri v e r s .”

Pan­tai 2 fea­tures a park above the sewage treat­ment plant, which Zaini said would be ben­e­fi­cial for the sur­round­ing com­mu­nity pend­ing tight se­cu­rity pro­ce­dures.
