Our mission is to win the heart of our clients by allowing our compelling-work and commitment speak for us.

Nothing is forever but our biogas system is forever. However, Waterworld Technology(WWT) got you covered. Leading Bio-gas company In Ghana – With our team of Biogas professional skilled personnel with over 22yers experience in Biogas installing both commercial and Residential biogas needs are covered

Labeled as the leading Biogas company In Ghana, we most importantly understand the Biogas system is a perfect replacement for the traditional septic tank system. The advantage of this system over the traditional septic tanks is that its ability to generate gas. That can be used for cooking hence reducing the cost of energy. How does it work? The system breaks down all fecal matter collected. Through the breakdown process called anaerobic digestion and methane gas is released as a by-product. This methane gas is very safe for cooking. And can further be processed into electricity through the use of biogas generators. Also, a waste product from the digestion process (digest) can be used as a liquid fertilizer.

How to Produced Bio-Gas?

Biogas is produced through the processing of various types of organic waste. It is a renewable and environmentally friendly fuel made from 100% local feedstocks that is suitable for a diversity of uses including road vehicle fuel and industrial uses. The circular-economy impact of biogas production is further enhanced by the organic nutrients recovered in the production process.

Biogas can be produced from a vast variety of raw materials (feedstocks). The biggest role in the biogas production process is played by microbes feeding on the biomass.

Digestion carried out by these microorganisms creates methane, which can be used as it is locally or upgraded to biogas equivalent to natural gas quality, enabling the transport of the biogas over longer distances. Material containing organic nutrients is also produced in the process, and this can be utilized for purposes such as agriculture.


Biomass is turned into gas by microbes

In the biogas reactor, microbial action begins and the biomass enters a gradual process of fermentation.

In practice, this means that microbes feed on organic matter, such as proteins, carbohydrates, and lipids, and their digestion turns these into methane and carbon dioxide.

Most of the organic matter is broken down into biogas – a mixture of methane and carbon dioxide – in approximately three weeks. The biogas is collected in a spherical gas holder from the top of the biogas reactors.

Digestate utilized as fertilizers or gardening soil

The residual solids and liquids created in biogas production are referred to as digestate. This digestate goes into a post-digester reactor and from there further into storage tanks. Digestates are well suited for uses such as the fertilization of fields.

Digests can also be centrifuged to separate the solid and liquid parts.

Solid digestates have use such as fertilizers in agriculture or in landscaping and can also be turned into gardening soil through a process of maturation involving composting.

Digestates are centrifuged to yield enough process water for the slurrification of biowaste at the beginning of the process. This helps reduce the use of clean water. The centrifuged liquid is rich in nutrients, particularly nitrogen, that can be separated further using methods such as stripping technology and used as fertilizers or nutrient sources in industrial processes

Turning diverse range of materials into gas

Biogas production starts from the arrival of feedstocks at the biogas plant. A diverse range of solid as well as sludge-like feedstocks can be used.

Materials suitable for biogas production include:

  • biodegradable waste from enterprises and industrial facilities, such as surplus lactose from the production of lactose-free dairy products
  • spoiled food from shops
  • biowaste generated by consumers
  • sludge from wastewater treatment plants
  • manure and field biomass from agriculture

The material is typically delivered to the biogas plant’s reception pit by lorry or waste management vehicle.

A delivery of solid matter such as biowaste will next undergo crushing to make its consistency as even as possible. At this point, water containing nutrients obtained from a further stage in the production process is also mixed with the feedstock to take the rate of solid matter down to only around one-tenth of the total volume.

This is also when any unwanted non-biodegradable waste, such as packaging plastic of out-of-date food waste from shops, is separated from the mixture. This waste is taken to a waste treatment facility where it is used to generate heat and electricity. Biomass that has passed through slurrification is combined with biomass delivered in the form of slurry to the biogas plant and pumped into the pre-digester tank where enzymes secreted by bacteria break down the biomass into an even finer consistency.

Next, the biomass is sanitized before entering the actual biogas reactor (digester). In sanitization, any harmful bacteria found in the material are eliminated by heating the mixture to above 70 °C for one hour. Once sanitized, the mass is pumped into the main reactor where biogas production takes place. Sanitization makes it possible to use the fertilizer product in agriculture.
