Landfill gas pumping trial: how the tests, wells and equipment prove gas yield, using a four-week, eight-well worked example.
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.
Mobile Landfill Gas Flare: How a Hinged-Chimney Unit Works
Mobile landfill gas flare explained: a skid-mounted 500 m³/h ground flare with a hydraulic-jack chimney, and when hiring before buying suits your site.
Replacing Discontinued Leachate Pumps: Confirm the Duty First
How to replace discontinued leachate pumps by confirming flow, head and liquid before ordering the equivalent model.
Ammonia Stripping for High-Strength Centrate: Choosing the Process
How a thermally driven ammonia stripper was selected for 450 m³/day of centrate at 21,400 mg/l ammonium, and what the alternatives would have cost in space, chemicals and complexity.
Solar PV Park Site Requirements: Planning a 30 MW Plant
What makes a good site for a utility-scale solar PV park: land, soil, grid access and a staged route from fatal flaw analysis to 30 MW.
Open or Enclosed Flare? Specifying an 800 m³/h Landfill Gas Flare for Engine Back-Up
For a southern European landfill gas site, an open flare was priced with an enclosed alternative. We look at the trade-offs and what the package includes.
Pyrolysis Trials: How to Test a New Waste Feedstock
What a full-scale pyrolysis trial measures and what it leaves out.
Flaring Low-Methane Landfill Gas: A Flare for 12 to 40% Methane
Old landfills produce gas too weak for a standard flare. A low-calorific shrouded combustor burns 12 to 40% methane at over 1,000°C.
Pyrolysis and Gasification Waste to Energy: How a Modular Plant Works
A step-by-step walk through a modular pyrolysis and gasification plant that turns refuse-derived fuel into steam and electricity, from feed compactor to flue gas treatment.
Chicken Processing Waste: Combining Anaerobic Digestion and Pyrolysis
A slaughterhouse produces waste that suits digestion and waste that does not. This design sends manure to a digester and the rest, with dried digestate, to pyrolysis.
MSW to RDF at a Landfill: What a Feasibility Study Checks
MSW to RDF feasibility study: the waste, fuel specification, process line and risks checked for a 450 t/day plant selling RDF to coal-fired factories.
What a Gas Equipment Service Contract Should Include
What should a service contract for landfill gas and monitoring equipment cover? Inspection intervals, response times, customer duties and exclusions, from a real example.
Landfill Gas Fuel Skid for a Gas Engine: Buffer Tank, Blower and Filtration
How a 500 m³/h fuel skid smooths gas pressure to a landfill gas engine, with a buffer tank, variable speed blower and a 3-micron filter.
How to Flare Hydrogen Safely: A Small Ground Flare Example
Hydrogen flare design: see how pressure switches, flame arresters and temperature control make a small 22 m³/h ground flare safe and stable to run.
Palm Oil Mill Effluent Biogas: Sizing to Site Load
Palm oil mill effluent biogas: why the same plant paid back in 1.5 or 3.5 years depending on how much power is used, plus delivery and financing routes.
Annual Condition Survey of a Leachate Treatment Plant: What It Covers
Leachate treatment plant condition survey: six scope items, four days on site and an independent report on condition and remaining life.
Methane Stripping Plant for Landfill Leachate: A Multi-Site Design
One four-chamber baffled aeration design adapted to four landfills of different size.
Fan Impellers and Shafts: Spares for Stripping Plant Blowers
How to order impeller and shaft spares for large plant fans by serial number, and what lead times to expect.
Landfill Gas Chilling and Flaring Before Gas Engines: A Worked Example
Landfill gas chilling and flaring before gas engines: a 3,500 Nm³/h worked example with chiller, blowers and standby flare.
Biogas Flare for an Anaerobic Digester: Why No Booster Is Needed
Biogas flare for an anaerobic digester: why a 1,000 m³/h flare can run without a booster and what pressure you must check first.
Pig Farm Biogas: Sizing a Covered Lagoon and Engines for 2,400 Sows
How a 2,400-sow pig farm can cover its own electricity demand from slurry, using a covered lagoon, H2S bioscrubber and two gas engines.
Ground Flare or Elevated Flare? A 2,600 m³/h Worked Example
Ground flare vs elevated flare: compare 1,000°C and 850°C designs, inlet pressure and trade-offs in a 2,600 m³/h worked example, and choose with confidence.
Pyrolysis of Food Processing Residue When an Oxidiser Already Exists
A food factory with its own thermal oxidiser needed a way to destroy production residue. A containerised 1.1 t/h pyrolysis module was designed to plug into the existing plant.
SBR and Reed Bed for Small Landfill Leachate: Treating 50 m³/day
How a sequencing batch reactor followed by a reed bed was proposed for a small landfill with no existing leachate treatment, and how the SBR cycle works.
Removing Iron from Landfill Leachate: Designing a Pilot Plant
Leachate iron removal: how a small pilot plant compares settling, coagulation, chemical addition and sand filtration to reach 1 mg/l.
