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 - Biogas Flare

HydroThane can deliver different types of emergency burners / flares for biogas - waste (water) treatment plants. Biogas flares have the task of temporary or periodic burning of biogas produced by an anaerobic process in case there is no possibility to use it for energy production.

DeAmmon - Nitrogen Removal System

DeAmmon is nitrogen-reduction process developed for nitrogen removal from high concentrated streams such as industrial waste water and sludge dewatering supernatant from digested wastewater sludge. The great advantages of the DeAmmon process compared to the conventional nitrogen removal are the significantly lower oxygen consumption and conversion to gaseous nitrogen without organic carbon.

FEATURED APPLICATIONS

Wastewater Treatment for the Chemical industry

In addition to the food industry, biological anaerobic and aerobic technologies can be applied in the chemical and pharmaceutical industry as well.

Typical for the chemical and pharmaceutical waste water is the high organic pollution, which is often limited to only a few components that can be present in high concentration. Every production site has its own unique effluent composition.

This type of effluents require tailor-made solutions. The Upflow Anaerobic...

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.

FEATURED SERVICES

Consultancy & Trouble Shooting Services

Based on many years of practical experience, HydroThane performs consultancy and troubleshooting services for biological waste water treatment plants. The actual performance of the plant is evaluated and recommendations will be formulated to improve or to optimize the performance of the plant. HydroThane is able to provide technical and technology support for different kinds of UASB, EGSB, solid waste digestion and biogas treatment plants that are on ...

Design & Process Philosophy

We firstly collect all the required data to make the design guidelines. Wastewater characteristics, effluent requirements and available space limitation are the main data that we need to know and then decide the proper process technology, the facility layout, the equipment characteristics and the complete process philosophy that will control the plant.

FEATURED TRAINING

Training

HydroThane delivers technical and technology-related training to the waste water treatment operators/manager during start up of the plant. New trainings for the operators can also be given by our engineers after a certain period of operation of the plant.
