biomethane potential test sets

Nautilus BMP model

The Nautilus model is a basic BMP test to evaluate the potential biogas volume. It counts with 15 differents reactors.  

This equipment has easy sample handling with robust stainless steel mixers. It has wide mouth HDPE reactor bottles for easy sample handling and minimum risk of damage if dropped. The high reactor volume (1 litre) allows larger sample and inoculum volumes to be processed. 

 

Nautilus model allows the access to reactors via air-tight port during the tests for pH monitoring, nutrient supplementation, or sampling. It can have extra ports to flush the reactors with biogas/nitrogen at the start of the test.

Also, its stainless steel paddles guarantee thorough mixing even for high solid substrates. The equipment has the novelty of mixing all reactors in the set at exactly the same intensity.

Pegasus BMP model

Pegasus model is also a BMP test to evaluate the potential biogas volume. This model counts with 3 reactors with a bigger volume than the Nautilus model (5l).  

 

This equipment is also easy sample handling and counts with robust stainless steel mixers. The material of the digester or tank reactor is 316 Stainless steel, but also with this model it is possible to store the digestate in a second tank attached to the reactors. The high reactor volume (3 litre) allows larger sample and inoculum volumes to be processed.

Main features of BMP

​• Non-disruptive in-test sampling, pH monitoring, and supplementation. 

​• Ambient to 85°C operation with minimum water loss.

​• Real time gas flow monitoring.

​• Data in csv format for ready use in Excel.

Fast set assembly with minimum water evaporation

• Easy to set-up tests at mesophilic or thermophilic conditions.

• Close fitting reactor heads through bath lid minimise heat and water loss even for high temperature operation.

• You can finish a test and be operational within minutes.

Easy sample handling and robust stainless steel mixers

• Wide mouth HDPE reactor bottles for easy sample handling and minimum risk of damage if dropped.

• High reactor volume ( 1 litre) allows larger sample and inoculum volumes to be processed; 6 x 2litre sets
also available.

• Access to reactors via air-tight port during the tests for pH monitoring, nutrient supplementation, or sampling. 

• Extra ports to flush the reactors with biogas/nitrogen at the start of the test.

• Stainless steel paddles guarantee thorough mixing even for high solid substrates.

Consistent mixing and temperature for all reactors

• All reactors are mixed using a single motor to guarantee mixing is exactly the same for all.

• One gas flow meter for all reactors in the set.

• CNC machined gas vessels (around 7ml), and bespoke calibration syringe enable regular quality control onsite.

Access your data remotely, by direct connection to PC

• Arduino software with automatic conversions and calculation, open source. A barometer in the Arduino logger continuously monitors atmospheric pressure for STP correction. Also, the temperature is monitored automatically.

• Bespoke software for data processing to csv format allows you to produce Excel graphs and tables at the
click of a button.

Biomethane Potential (BMP) is a biological test to evaluate the potential methane/biogas volume generated from a material (substrate). The test comprises two elements: a) Inoculum and b) sample. Inoculum (seed) is fed an amount of sample on a VS ratio basis (F/M), gas yield is then measured continuously in real time. The gas is measured and converted to units of ml/gram VS substrate at Standard conditions for Temperature and Pressure (STP).

BMP equipment developed by Anaero Technology allows consistent evaluation of feedstock biogas and inhibition potential. The different models of BMP sets offered by Anaero Tech are shown below: 

All BMP sets counts with a Gasflowmeter, where the gas generation is measured using a liquid displacement gas flow meter.

 

The gas flow meter is a single Perspex block with 15- 0.2l cells and Perspex tumbling buckets of around 7ml gas volume. A spare cell (cell 16) is used for automatic monitoring of temperature. A barometer in the Arduino logger continuously monitors atmospheric pressure for STP correction. The liquid in all cells is interconnected to keep them at exactly the same head, for equal head pressure in all reactors (liquid specifications: Table 2). Each cell has a tumbling bucket with active volume of around 7ml (easily calibrated by user- See section 3.1). The smaller measuring volume allows for better recording of the kinetics of the test, especially after the initial phase of high gas production. However, the smaller the measurement volume, the larger the potential error from uncounted gas bubbles. To minimise potential error during gas measurement a minimum counting volume of 5ml has been designed and attention has been paid to the size of gas bubbles entering the measuring vessel. The diameter of the nozzle orifice where gas enters the measurement cell is machined to 1.5mm, reducing the size of gas bubbles and minimising the potential impact of uncounted odd bubbles by-passing the tumbling bucket.
