HydroThane is a group of companies specialized in industrial waste water treatment, water recycling, solid waste digestion and biogas treatment. HydroThane is a company with more than 30 years of practical experience in the design, engineering and construction of biological waste water treatment plants for industrial applications. HydroThane has an excellent reputation and proven track record with industrial clients in different types of industries, such as beverages, breweries, chemical / pharmaceutical, pulp & paper, food, (bio) ethanol/distilleries, etc. From its headquarters in the Netherlands, HydroThane operates globally with own local daughter companies and/or local partnerships. The name HydroThane is a combination of two words - Hydro (water) and MeThane (gas), which indicates their biological anaerobic sustainable treatment processes.

About Us

HydroThane develops and supplies sustainable treatment processes for industrial applications.

Innovation of the technologies is not only based on pure technical grounds, but economical running of the plant is also ahead of our preoccupations.

Purification of waste water with highly efficient anaerobic systems that produce energy from waste water is one of the key characteristics of the technologies of HydroThane. Treatment of the produced biogas from the anaerobic HydroThane processes has been also developed by HydroThane engineers based on years of practical experience.

Next to their anaerobic processes, HydroThane also offers a range of aerobic biological treatment technologies for different kinds of industrial waste waters, which can be combined to reach strict local discharge limits.

Technologies:

Anaerobic Technology
Anaerobic treatment of waste (water) is a biological method characterized by the production of methane (CH4). All the active micro-organisms belong to the group of anaerobic bacteria, i.e. bacteria which are able to and in most cases can only exist in an environment which excludes oxygen. In this context, methanogenic bacteria are a key component.

The anaerobic degradation process of organic material occurs stepwise.

There can be distinguished four steps:

  • Hydrolysis
  • Acidification
  • Acetogenesis
  • Methanogenesis.

The anaerobic process removes the bulk of COD from the waste (water) by converting it into biogas (= methane + carbon dioxide) at low operational costs.

Aerobic Technology
In order to achieve final effluent requirements, most often anaerobic treatment is not sufficient and it needs some post aeration step. HydroThane is able to give complete solutions for aerobic treatment applications as post treatment to an anaerobic treatment plant, or as the main treatment step, depending on the case and type/quantity of wastewater.

Aerobic Biological treatment is carried out based upon the principles of activated sludge process with biological nutrient removal (Nitrogen and Phosphorus) and in some cases separated sludge regeneration.

Oxygen supplied continuously activates the bacteria in order to start degrading the organic content, which will be subsequently converted to CO2 and excess biomass.

The presence of nitrogen in any form requires the application of aerobic biological nitrification-denitrification in order to remove it in the desired level, but also to avoid this process to take place in the final clarifiers and as a result to have floating biomass.


Biogas treatment & utilization
Energy generated from renewable sources such as biogas, solar or wind is called green power / green energy. Green energy / power is a term used to describe sources of energy that are considered to be environmentally friendly and non-polluting.

These sources of energy may provide a remedy to the systematic effects of global warming and certain forms of pollution.

Biogas utilization can occur in waste water treatment plants, solid waste digestion plants and solid waste landfills, where the biogas can be collected and used. When biogas is produced by means of an anaerobic process, the biogas consists of methane (CH4) and carbon-dioxide (CO2) along with some trace gasses such as water vapor, hydrogen sulphide (H2S), nitrogen (N2), hydrogen (H2) and oxygen (O2).

The concentration of hydrogen sulphide in biogas can vary from 250 ppmv up to several volume percentage, it has an offensive odour of 'rotten eggs' at concentrations as low as 50 ppbv and is toxic at concentrations above 100 ppmv.

At some applications H2S must be removed before the biogas can be given for utilization, for reasons of health, safety, environment and due to the fact that hydrogen sulphide gas is corrosive (can damage equipment like; gas engines (CHP), boilers, piping etc.)

Desulphurization of the biogas is also required when biogas is upgraded to natural gas quality for injection into the gas grid.

FEATURED PRODUCTS

HydroThane STP - Model CSP - Chemical Desulphurization Process System

HydroThane STP CSP stands for chemical deSulphurization Process and the principle of Hydrogen Sulphide (H2S) removal from the biogas is based on the transfer of gaseous hydrogen sulphide to the water phase.

ADI-AnMBR - Anaerobic Membrane Bioreactor

The ADI-AnMBR process is a high rate anaerobic process that uses a submerged membrane barrier to perform the gas-liquid-solids separation and reactor biomass retention function. This near-absolute barrier to solids ensures efficient system operation and stability, even under high organic loading and intense mixing scenarios.

FEATURED APPLICATIONS

Wastewater Treatment for the Bioenergy Industry

The waste (water) streams from the production of (bio) ethanol or ethanol spirits are generally very suitable for anaerobic treatment, due to their organic compounds. 

The effluent streams produced by the different production processes are influences by a great number of parameters such as, process design, milling process, type of raw material, etc. This requires special attention in the design of the treatment plant for this type of industry. 

Typi...

Wastewater Treatment for the Pulp & Paper Industry

The pulp and paper industry generates large volumes of highly heterogeneous waste waters containing compounds from wood or other raw materials, process chemicals and compounds formed during processing.

The waste water streams from pulp and paper vary greatly in concentration and composition. The waste water from mechanical pulping (TMP) and secondary fiber pulping as well as the condensates from chemical and semi-chemical pulping are typically non-toxic to methanogenic degradation...
