OTAR® and the Nitrogen Circular Economy: Nitrogen as a Resource, Not a Waste
A nitrogen circular economy starts with two facts. First, the fertiliser industry uses roughly 200 million tonnes of nitrogen every year. Almost all of it comes from atmospheric nitrogen, fixed with...
Ammonia Recovery for Food Processing Wastewater: The Opportunity for Australian Processors
Ammonia recovery for food processing wastewater turns a cost into a product. A large dairy processing plant may generate enough ammoniacal nitrogen to produce 200+ tonnes of ammonium hydroxide per...
Landfill Leachate Ammonia Treatment: A Proven Compliance Solution
Landfill leachate ammonia treatment defeats many biological systems, so several Hong Kong facilities use thermal stripping instead. They run OTAR® Variant 1 on waste heat from landfill gas engines....
Ammonia Recovery vs Struvite Precipitation: Choosing the Right Nutrient Recovery Technology
Ammonia recovery vs struvite precipitation comes down to one question: which nutrient do you need to recover? Struvite mainly recovers phosphorus, while OTAR® mainly recovers nitrogen. For most...
Building the Business Case: OTAR® Return on Investment
OTAR®'s business case rests on three simultaneous value streams. Together, they frequently produce payback periods that compete favourably with conventional capital investment.For most operators,...
OMRI-Listed Ammonium Hydroxide: OTAR® Variant 2’s Premium Product Advantage
OTAR® Variant 2 absorbs stripped ammonia into water instead of acid. As a result, it produces ammonium hydroxide eligible for OMRI listing (or equivalent Australian organic input certification) — a...
The Science of Thermal Ammonia Stripping: How OTAR® Works
Thermal ammonia stripping is not a new idea. But OTAR®'s modular system is different. It combines stripping, absorption and heat management into one platform, delivering a step-change in efficiency,...
The OTAR® Ammonia Recovery System: Five Variants Explained
OTAR has more than 20 years of operational experience and proven installations across Asia. Its five-variant architecture ensures there is a suitable ammonia recovery system for every US facility,...
How Much Is the Ammonia in Your Waste Stream Worth in Australia?
Most Australian facility managers know exactly what it costs to meet strict trade waste limits. However, few have calculated how much asset value leaves their site daily through their wastewater...
