WesTech Supplies New Biological Treatment Technology to the Philippines

Quezon City, Philippines, has installed an STM-Aerotor™ Biological Treatment System from WesTech Engineering in its Baesa District.

Currently, only a fraction of the wastewater in and around Manila is treated. The Philippine Government is now taking a more active role in the enforcement of the Philippine Clean Water Act of 2004. Milestones and goals are being mandated by the government for the treating of the wastewater from roughly 13 million residents, representing a tremendous need for simple and cost effective treatment systems.

In order to meet new government standards and provide a simple and cost effective treatment system, Maynilad selected the STM-Aerotor for their treatment process because of its ability to meet the regulations, fit into a tight footprint and use much less power as compared to all other technologies.

Power consumption for the STM-Aerotor is on average, 80% less than conventional sequencing batch reactor (SBR) technologies, which are common in the Philippines. The STM-Aerotor uses both Integrated Fixed Film and Activated Sludge (IFAS) technologies as part of a process that provides biological treatment for municipal wastewater. The system in Baesa is the first of its kind to be installed in the country.

As this treatment plant was constructed in the middle of an existing community, it was installed in a building made to look like the other homes in the neighborhood. This makes the treatment plant inconspicuous. The new installation serves 2,000 residents.

After visiting Manila and seeing firsthand how polluted Manila Bay is, I know WesTech, in conjunction with our local partner First EnvironTech Alliance, can make a difference by providing a cost-effective solution for helping to clean up the polluted waterways and bays, said Jon Richens, WesTech Group Leader, Process Applications. Our installation is already making a difference for the environment and the quality of life for the people who live there.

WesTech has been awarded three additional contracts in the country using the STM-Aerotors, as well as our COP™ Clarifiers, and CleanFlo™ All-In-One Combined Headworks Systems (discontinued).
