Ammonia stripping for wastewater compared: steam stripping, thermal air stripping and a vortex stripper for a 154 to 180 m³/h duty.
Organics Articles
Organics Group has spent more than thirty years turning ammonia-laden wastewater, landfill gas, organic and food waste, palm oil mill effluent into revenue with biogas flaring technology deployed on over 300 projects worldwide, commissioned across Europe, Asia, the USA and Oceania. This collection brings that work out of the project archive written for the engineers, regulators and operators who decide which technologies is going to solve their problems.
Annual Condition Survey of an Ammonia Stripping Plant: What It Covers
A one-day annual condition survey can show whether a thermal ammonia stripping plant is still in good order. This is what it covers and what comes out of it.

How to replace an obsolete steam generator level control by keeping the compatible probe and swapping the electronics.
MVR Ammonia Recovery Plant Layout: Keeping the Vapour Circuit Compact
MVR ammonia recovery plant layout: why the stripper, compressor and condenser must be one compact group, with access and loading rules.
Anaerobic Membrane Bioreactor for Palm Oil Mill Effluent: A 1.5 MW Design
How an anaerobic membrane bioreactor (AnMBR) was sized for a 60 t/h palm oil mill and why a steel tank beat a lagoon on footprint and rainy-season build risk.
Biogas Dewatering with a Chiller Skid: Protecting Gas Engines from Condensate
Biogas dewatering with a chiller skid: cool to a 20°C dew point and filter to 3 microns to protect engines from condensate and ammonia.
Small-Scale Pyrolysis Waste to Energy: Why Pair It with an ORC, Not a Gas Engine
Small-scale pyrolysis waste to energy: a containerised 5 tonne-a-day plant making 50 kWe with an ORC, and why an ORC beats a gas engine.
When an Open Flare Is Enough: A 170 Nm³/h Biogas Flare for Farm and Mill Digesters
Open flare for biogas: when a 170 Nm³/h elevated flare is enough for a small digester, and how it compares with an enclosed flare.
Ammonia Stripping Waste Heat at Gin Drinkers Bay
Organics designs thermal ammonia stripping systems that match heat source to leachate chemistry. If you have waste heat from flaring or thermal oxidation, the next step is a site heat-balance discussion to see whether a similar circuit fits your flow and duty.
Covered Lagoon Biogas for Palm Oil Mill Effluent: Process Guarantees and Scope
Covered lagoon biogas for POME: guarantees of 85% COD removal and 55 to 60% methane, with cooling, lagoon and gas handling scope.

What a bidder asked after the site visit for a fruit and vegetable market digester tender, and why each question changes the price and risk.
The WENT Landfill Plant: Thermal Ammonia Stripping System
The WENT landfill leachate treatment plant demonstrates how a thermal ammonia stripping system integrates waste-heat recovery, modular packed-tower construction and conditioned air humidification to remove ammonia from high-strength landfill leachate at scale.
Coal Dust Pyrolysis: How a 1 MW Power Plant Is Planned
Outline design for turning coal dust into about 1 MW of net power, and the cooling decision that shifts the output.
