No solution exists to remove methane from water at scale.

Until now

Technology design and development

We design solutions to recover the most methane from water using the least energy. We achieve this firstly through a methane monitoring system and data platform that identifies when and where methane is present, then secondly through an energy efficient technology recovery solution. The captured biogas can be used to power the system and help support the power requirement of onsite activities.

Bluemethane technology is cost-effective, energy-efficient, low maintenance and has a modular design for ease of manufacture and supply.

Beginning our technological journey

In response to a convergence of factors including evolving awareness, industry leadership, and growing social pressure in Europe and the USA, there’s an intensified focus on mitigating methane emissions. This emphasis is particularly pronounced within the water utilities and wastewater sectors, driven by the imperative to achieve ambitious net-zero carbon targets.

Located at Cranfield: a hub for water research

Bluemethane launches its operations in the United Kingdom, strategically positioned at Cranfield, renowned for its water research excellence. The UK serves as an optimal starting point, with its water utilities committing to operational net-zero status by 2030. However, existing technology falls short of realising this vision. Aligning with the United Kingdom Climate Change Committee and legislation, our initiatives resonate with counterparts across the EU.

Bluemethane technology sits neatly into existing wastewater processes

Our methane capture technology

The process for capturing methane from water

1. INLET

The post digested sludge flows from the anaerobic digestor to the Bluemethane system

2. BIOGAS FIRST STREAM

The initial gas volume realised through the first methane separator is collected here

3. PROPRIETARY TECHNOLOGY

At this stage we use a specific degassing process and technology to separate the methane and slurry / water.

4. SECONDARY SEPARATOR

The wastewater continues to flow into the secondary separator in which a light vacuum encourages further methane release.

5. BIOGAS SECONDARY STREAM

Collection of the methane and carbon dioxide to a buffer tank.

6. OUTLET

The methane-poor slurry flows out of the secondary separator into post anaerobic downstream processing.

ENERGY EFFICIENT

Using existing infrastructure, Bluemethane can both decarbonise and remain energy positive, providing additional energy to support a number of onsite activities.

SIDESTREAM PROCESS

Our system is a sidestream technology that can recover methane from multiple process streams. As an example within a wastewater process it can recover methane from raw sewage, post-digested sludge and as an enabler of full flow anaerobic treatment.

LOW RISK

The Bluemethane system has already been proven to capture methane with an efficiency of circa 70%. It has been designed to fit within existing systems removing both methane and carbon dioxide and thus improving the overall wastewater system efficiency. Moving parts are purposely limited with little maintenance required.
