Design, build and upgrade.

Aerated leachate lagoons at the Bukit Tagar sanitary landfill

Scope of work

Thirty years of leachate work

  • Collection and pumping

    Pumps, floaters, pipelines.

  • Biological treatment

    SCADA and electrical boards.

  • Landfill works

    Cells and gas extraction.

Process

The leachate train

  1. Collection

    Leachate drained from the cells and pumped to the plant.

  2. Equalisation

    Flows and strength evened out before treatment.

  3. Aeration

    Aerators drive biological breakdown in lined lagoons.

  4. Flotation

    DAF strips suspended solids and residual organics.

  5. Dewatering

    Decanters and presses turn sludge into cake.

  6. Discharge and monitoring

    Treated effluent tested against the discharge limits.

Questions

Frequently asked

What is landfill leachate and why does it need treatment?

Leachate is the liquid that drains through a landfill. It carries high organic load, ammonia and dissolved metals, so it must be collected and treated before discharge to protect rivers and groundwater.

What leachate treatment does Usaha Pammek build?

Collection and pumping, aerated lagoons with surface and paddlewheel aerators, dissolved air flotation, return activated sludge systems, sludge dewatering with decanters, filter presses and multi-disc screw presses, SCADA controls and the electrical boards behind them.

Which landfills have you worked on?

Bukit Tagar in Selangor, Sungai Udang in Melaka, Rimba Mas in Perlis, Papan in Perak, Jinjang Utara in Kuala Lumpur and Floridablanca in the Philippines.

Which discharge standards are plants designed to?

Plants in Malaysia are designed to the leachate discharge limits under the Environmental Quality (Control of Pollution from Solid Waste Transfer Station and Landfill) Regulations 2009.
