HydroThane, a company with more than 35 years of practical experience, has an excellent reputation and proven track record with industrial clients. The quality of our technologies combined with the excellence of our services makes us stand above our competitors.
Yes. HydroThane reactors are fully automated! Operation is therefore very easy. The most important parameters to monitor in an anaerobic process are pH, temperature, nutrient dosing, biomass characteristics (organic content) and wastewater characteristics.
Anaerobic treatment covers a big range of applications. HydroThane develops and supplies sustainable treatment processes for industrial applications, including breweries and beverage, chemical, pulp and paper, food, bioethanol, dairy and many more!
Solids are an often occurring pollutant in wastewater. Solids, when consisting from organic material, can be taken out using screens or clarifiers and can be degraded in anaerobic solid waste digesters to produce biogas.
Anaerobic biomass is biomass consisting out of a mixture of bacteria and structural solids that is able to degrade waste and/or wastewater in the absence of oxygen and produces biogas with a high methane content.
The granular biomass growth depends on the wastewater composition. Also, not all bacteria will grow in granules and will therefore be flushed out of the system. The net growth of granules is usually about 1-2% of the kg degraded COD per day.
Unlike Aerobic sludge, anaerobic sludge is of great value. Because the growth of anaerobic sludge is slow compared to aerobic sludge, it is more scarce. The biomass can be sold to others who may need it or can be kept in storage for later use.
The lifecycle of the bacteria inside the granule differ from sort to sort. Additionally the certain components in wastewater could speed up this process. However, the lifecycle is not that important. The bacteria are constantly reproducing. Therefore the bacteria in your system are always “fresh”.
Granular anaerobic biomass is effective since it contains all bacteria for waste and/or wastewater degradation in one granule. When a certain substrate is presented to the granule, it will be absorbed and degraded step by step by different groups of bacteria contained in the same granule. It is like a highly productive “city” of bacteria that keep each other alive.
Bacterial cells are composed majority by Carbon, Oxygen, Nitrogen and Hydrogen but also some other micronutrients, such as, Phosphorous, Potassium, Sodium, Magnesium, Iron, Cobalt, etc. Sometimes there are not enough nutrients present in the wastewater to be treated. HydroThane developed special mixture of micronutrients to avoid any scarcity to the process.
Macro-nutrients -such as N and P- are essential for the growth of anaerobic bacteria. However, the nitrogen and phosphorus requirement for the anaerobic treatment of an industrial wastewater is only a fraction of the amount needed for aerobic processes (typically more than 10 times less).
Biogas is a mixture of gases that are produced when organic matter is broken down by anaerobic microorganisms, in a process called anaerobic digestion. Biogas is primarily composed by methane (CH4) and carbon dioxide (CO2) and may have small amounts of hydrogen sulfide (H2S), moisture and siloxanes.
Yes. During anaerobic digestion biogas and biomethane is produced, which can be used to replace fossil fuels and therefore reduce emissions. Additionally green fertilizers can be produced and carbon is re-used which contributes to a negative carbon footprint.
1 Nm3 of pure methane has an upper calorific value of 39.8 MJ (1000 Kcal = 4.18 MJ). When we don’t take in account the heat of condensation, the lower heating value (35.9 MJ/ Nm3 CH4), should be considered.
Biogas is useful for people and industry due to its high methane content. This biogas can therefore be used for heating purposes, running a gas engine to produce electricity or can provide gas to houses in your surroundings.
The amount of biogas produced from your wastewater is dependent on the composition of the wastewater and pH. However, the amount of methane, the most useful constituent of the biogas, is known. The methane production is 0.35 Nm3 per kilogram degraded COD.
Depending on the wastewater’s composition, the biogas may contain toxic and corrosive H2S gas. Scrubbing of H2S is the removal of this gas which reduces toxicity and increases life expectancy of any equipment the biogas is used in.
There are several types of scrubbers on the market each for his own use. Most popular scrubbers used to this day are chemical (caustic) scrubbers, biological scrubber or a combination of both. The so-called biochemical scrubbers.
