Efficient way to digest biodegradable material and produce energy
Anaerobic digestion is a biological process in which biodegradable material is broken down by micro-organisms. The process produces biogas which may be combusted to generate heat and electricity or processed further into transportation fuels and renewable natural gas as a biomethane.
HLAD® (High Loaded Anaerobic Digestion) process is a comprehensive solution for biodegradable waste management for municipalities, industry and agriculture. HLAD® process features lower capital investment, higher biogas yield and lower residual volumes compared to conventional digestion. HLAD technology especially bioreactor dimensioning and unique mixing dynamics enables HLAD® process to have significantly higher biological load. This results in high biogas yield and complete end product maturity. All this makes HLAD® process a superior solution compared to other anaerobic digestion technologies.
HLAD® process is an efficient way to digest any kind of biodegradable materials and produce energy at the same time. HLAD® process is also able to handle a wide variety of different types of feed materials. The feed material can be for example food remnants, fats, sludge, corn, grass, manure, dung etc. and they can be processed as a single material or as a mixture. The biogas produced can be utilized as a gaseous fuel as it is or to produce electricity and heat/cool by CHP. Biogas is also possible to upgrade to biomethane to be used as vehicle fuel.
HLAD® process has been a proven technology since 1999 in Forssa city wastewater treatment plant which makes it the oldest running high loaded anaerobic digestion process world wide.
- High loading rate and sufficent retention time -> Higher biogas yield
- More biogas -> More revenues
- Complete bio-reduction -> Less non smelling solid end product
- Old digestion process possible to upgrade to HLAD® process
- Flexible and reliable technology
