The private water company Maynilad operates in the western part of the Manila metropolitan area in the Philippines, supplying drinking water to over nine million people. Maynilad runs a total of three water treatment plants, one of which – situated in the Putatan barangay in the city of Muntinlupa – uses inge^® ultrafiltration technology.
The water is drawn from the Laguna Lake, which lies to the south-east of Manila and borders Muntinlupa. The lake water undergoes a rigorous filtration process before being used to supply 490,000 people with a total of 150 million liters of clean drinking water a day.
Purifying the water poses some significant challenges, however. As well as seasonal variations in water quality, the lake becomes also soiled by industries that include a nearby slaughterhouse and extensive fish farming right next to where the water is extracted. Despite the often extremely poor quality of the lake water, the ultrafiltration models have been running without a hitch for the past two years, delivering consistently clean water that meets the required quality standards.

Ultrafiltration in water treatment

There is a growing awareness of the importance of professional drinking water treatment and eco-friendly methods of wastewater reuse and recycling – not just in arid regions, but worldwide. Against this backdrop, ultrafiltration (UF) has taken on an increasingly important role over the past 15 to 20 years in a broad range of water treatment applications.
As treatment plants get bigger, so do the challenges involved in building and running them. As a result, the quality and reliability of their components has become a key factor, and comprehensive technical support from component suppliers has become a crucial part of successful plant engineering projects.
