The Challenge

The sewage treatment at UP Arboretum, UP Diliman Campus in Quezon City, Philippines is located on the oldest university campus in the country. There was a requirement for the quality of the effluent being treated there to be improved, to meet the new DENR Administrative order 2016-08 effluent quality requirements for Class C waters.

The Solution

To meet the new consents, the operators identified the need to design and build a new sewage treatment plant that was capable of treating 5000m³/day, in addition to the existing 7 million litres per day (MLD) sewage treatment plant. However, space was at a premium, so the footprint of the new works needed to be compact. Nereda technology proved the ideal solution to overcome this typical urban spatial challenge as it takes up significantly less space than traditional treatment options. The new treatment works will treat sewage from 30,000 people from UP Diliman Campus and other commercial establishments in the area, including a Technohub located on nearby Commonwealth Avenue.

Nereda is a wastewater treatment technology that relies on aerobic biological action to purify wastewater before returning clean water to the environment. The Nereda process has already been successfully tried and tested around the world, although this is its first application in the Philippines. It requires fewer chemicals than conventional wastewater treatments and meets strict purification standards. This innovative, sustainable process was developed in The Netherlands.

The Outcome

On the new plant’s completion in Summer 2020, the influent sewage will be divided between the existing 7 MLD plant and the new 5 MLD Nereda treatment plant. The waste granular sludge from the Nereda plant will then be fed to the 7 MLD plant to improve its overall performance. Once the new plant has demonstrated success results, the operators will look to upgrade the original plant too.

Nereda technology in brief:

  • Small footprint
  • High quality effluent
  • Improved water quality
  • Low capital expenditure and operational costs
  • Reduced lifetime operational costs
  • Sustainable wastewater treatment
  • Energy savings
  • Tried and tested technology
