Organics Oceania provides free data sheets of our wastewater treatment, ammonia recovery, ammonia stripping, biogas and renewable energy systems . All datasheets include the product detail, a description of the the process and some details of installations that have been carried out.


Advanced Thermal Ammonia Stripping

Thermal stripping provides a low cost alternative to the use of carbon addition in a biological process.

The thermal-stripper breaks the ammonium-ion bond with heat alone. This action converts ammonia into a gas, NH3, which can be driven from the liquid-phase with suitable quantities of air.

In a single pass, it is possible to achieve greater than 98.5% removal of ammonia by this mechanism.

Organics has developed a low-NOx combustion process for flaring waste gas which involves Exhaust Gas Recycle. When combined with the thermal destruction of ammonia gases the result is extremely low NOx emission levels. Heat from the thermal-oxidiser used to destroy ammonia is recovered in conventional heat-recovery economisers and used to power the thermal ammonia stripper.


Ammonia Recovery – Acid Scrubbing

An alternative to destroying the stripped ammonia is recovery with the use of an acid scrubber.

The Advanced Thermal Ammonia Stripper with Ammonia Salt recovery has been developed and patented by Organics to provide a fundamental option for disposing of, or benefiting from, ammonia removed from wastewater streams. Typically, nitric, sulphuric or phosphoric acid may be used to create the ammonium ion salt.

In this arrangement, a thermal oxidiser for ammonia-gas destruction is not required. The single important input remains waste-heat with which to drive fracturing of the ammonium ion into ammonia gas.

Such wasteheat can be taken from any suitable source, such as a gas engine’s exhaust, excess process steam or any other heat-source where energy is available for disposal. Once the process is commenced, the exothermic reaction encountered in salt formation offers the potential of significant energy savings.


Ammonia Recovery – Water Scrubbing

The Advanced Thermal Ammonia Stripper with Ammonia Recovery has been developed and patented by Organics to provide another option for disposing of, or benefiting from, ammonia removed from wastewater streams.

The ATASAR process provides the option of either ammonia recovery as an anhydrous liquid under pressure, or as ammonium hydroxide, held in water. The thermal oxidiser is replaced by a cold-water scrubber.

The single important input remains wasteheat with which to drive the chemical reactions. Heat is required for both heating the feed into the ammonia stripper, as well as to drive the absorption chiller serving the cold-water scrubber.

Such wasteheat can be taken from any suitable source, such as a gas engine’s exhaust, excess process steam or any other heat-source where energy is available for disposal.


Biogas Feed Train

Biogas may be produced from many different biodegradable organic substrates. In general, however, its composition will be very similar, being comprised mostly of

  • methane, at between 40% and 65% by volume
  • carbon dioxide, at between 30% and 40% by volume
  • a number of trace gases.

Some trace gases, such as hydrogen sulphide and siloxanes, can be particularly detrimental to gas utilisation systems and may need to be reduced to acceptable concentrations.

In outline terms, a biogas feed train will consist of a gas blower, normally with automatic feed or suction pressure control and equipment to treat the biogas. Treatment may be in the form of reducing trace gas composition, reducing or removing bulk gases, drying the biogas to acceptable levels of moisture content and filtering the biogas to a micron level for particulates.

Organics offers a range of such technologies, as a single package of plant, to perform the duty of preparing biogas for use. With the correct application of this technology, biogas, even from difficult sources, may become a reliable fuel for long-term economic use.


Landfill Gas

Landfill gas power generation is a tried and tested mechanism not only to control a highly polluting greenhouse gas but also to take advantage of a natural resource, a direct result of man’s activities, to generate power.

It is an excellent example of the circular economy in action in that resources are recycled not only to meet our daily activites but also to reduce the carbon footprint of those activites.

Organics has been involved in landfill gas control and power generation since 1985 and was intrumental in the construction of early power generation plant in the UK. Landfill gas can not only be used for power generation but also for the production of biomethane, a clean fuel that can be used in vehicles or exported to a natural gas grid. 


Waste as an Energy Resource

Organics has been in the waste-as-a-resource business for over thirty years. During this time the company has provided over five hundred projects around the world with equipment to make beneficial use of a wide range of waste types. It has been a logical extension of Organics’ scope to develop Refuse Derived Fuel (RDF) equipment and facilities.

RDF production is an essential and integral part of a modern society’s waste management options. By means of a range of transformative processes, waste can be converted into a useful product which can replace high-grade fossil fuels. Subject to form, moisture content and calorific value, RDF can be used in a range of industrial processes from fluidised bed combustion, to cement kilns and in RDF-fired power generation facilities.


SMART Low NOx Flares

Performance NOx – When operating at its peak settings, the Organics SMART flare will achieve emmissions of less than 25 mg/Nm3 (dry gas at 3% Oxygen). At 50% methane this latter is approximately equivalent to a Mass Emission Rate of .025 lb Nox/MMBtu.

Carbon Monoxide – Levels of carbon monoxide will be below 40 mg/Nm3 (dry gas at 3% oxygen), which is approximately equivalent to a Mass Emission Rate of 0.6 lb/MMBtu at 50% methane.

Trace gases – Vinyl chloride, benzene and non-methane organic carbons have all been measured by a NAMAS approved laboratory to be destroyed to greater than 98% efficiency.

Ammonia – When input to a thermal oxidiser equipped with SMART flare technology, an inlet concentration of mg/Nm3 (dry gas 3% oxygen) resulted in a 99.95% removal efficiency and a total Nox load of <100 mg/Nm3.

This latter is well within the requirements of the German TA Luft and the propoesed UK Environment Agency Landfill gas emission standards.
