SET 2

The largest STP in the Philippines to date is located in _____ ____.

Ilugin Pasig STP has the capacity of ______.

• 100 MLD

• 165MLD

• 120MLD

• 155MLD

This follows a sequence of processes which involves activating the sludge and then followed by clarification and decantation.

• Sequencing Batch Reactor

• Membrane Bioreactors

The process begins with anoxic filling. The tank is filled up to 60% of the tank's capacity. The aim of this step is denitrify your sewage to produce N2 gas.

• Filling

• Reaction

• Settle

• Decant and Settle

Air is introduced from the bottom of the tank using air blowers. Careful design of air blowers and its placement in tanks is of high importance to effectively mix the substrate and remove the carbonaceous materials.

• Filling

• Reaction

• Settle

• Decant and Settle

Air is stopped and sludge is settled to the bottom of the tank. Heavier materials settles to the bottom leaving a clear water above the sludge.

• Filling

• Settle

• Reaction

• Decant and Settle

Operators begins to observe clear water. Treated water is decanted through decanter system and transferred to final disinfection tanks.

The sludge is allowed to sit for a while and the excess sludge is pumped to the WAS tank for solids treatment and disposal.

• Settle

• Decant

• Decant and Settle

• Decant and Idle

_______ a term coined to describe high-grade reclaimed water produced through advanced process.

_______ are a compact wastewater treatment system that produces high-quality effluent using membrane filtration

• Membrane Bioreactors

• Conventional Activated Sludge

• Sequencing Batch Reactor

This involves separation of sludge from treated water by sedimentation in secondary clarifier

• Membrane Bioreactors

• Conventional Activated Sludge

• Sequencing Batch Reactor
