Netherland’s Largest WWTP started producing Biomethane with Bright Biomethane’s System

Netherland’s largest waste water treatment plant (WWTP), WWTP Harnaschpolder of the Delfland Water Authority in Den Hoorn, started to produce its first biomethane, also known as renewable natural gas. The Bright Biomethane biogas upgrading system successfully injected the first biomethane into the gas grid of network operator Westland Infra yesterday.

This versatile installation makes use of an innovative pretreatment system which delivers biogas to several processing systems – the biogas upgrading system, existing CHP and boiler, interchangeably or at the same time.

By utilizing the upgrading system, the biogas is upgraded to biomethane with a capacity of 800 Nm3/hr. The produced biomethane is injected into the gas grid. Instead of low-calorific biomethane (L-gas), high-calorific biomethane (H-gas) can be also produced in the near future.

Energy transition

The Delfland Water Authority is one of the 21 water authorities in the Netherlands. Production of biomethane is a significant step forward in the energy transition and the ambition of the organization to create a working environment that is as sustainable and circulair as possible.
