Results could show more than 100% emission of ammoniacal nitrogen when combining independent experiments.

The ammoniacal nitrogen levels can be lowered using a sequencing batch reactor.

The same process can remove ammoniacal nitrogen by a nitrification - denitrification route.

Precise method for determining ammoniacal nitrogen in eggs.

Oils and greases and ammoniacal nitrogen were not affected.

An estimate is derived for the total ammoniacal nitrogen (TAN) that is excreted.

The method for the determination of free or combined ammoniacal nitrogen is given below in Section 13.2.8 of Part II.

Several approaches may be available to decrease the total ammoniacal nitrogen in manure or to reduce ammonia losses from animal housing, manure storage and land application.

Among other pollutants, this system removes the leachate's high Biological Oxygen Demand, the ammoniacal nitrogen and ferrous iron contents.

Increased sulfide has been shown to inhibit NH-N (ammoniacal nitrogen, an ammonium salt) uptake within the plant.

Ammoniacal nitrogen (NH-N)

The indicator will be based on total ammoniacal nitrogen and will cover aspects of feed nitrogen management and manure management as well as fertilizer sources.

The reduction of Biochemical Oxygen Demand (BOD) and ammoniacal nitrogen load on the ponds was necessary to minimise the potential for odour production.

The values of ammoniacal nitrogen in water or waste liquids are measured in milligram per liter and are used for specifying water treatment systems and facilities.

At the surface particulate matter is filtered out while below this the passage of oxygenated water creates a biologically active layer which consumes bacteria and biodegrades ammoniacal nitrogen etc.

Ammoniacal Nitrogen (N or NH3) The nitrogen in sewage is assessed as ammoniacal nitrogen.

Oxidized nitrogen is reduced to ammonia with Devarda's alloy, and this, together with any free ammoniacal nitrogen, is removed from the sample by boiling the alkaline solution.

This type of amendment creates acidic conditions (pH less than 7) in the litter, resulting in more of the ammoniacal nitrogen being temporarily retained as ammonium rather than ammonia.

For example, phase feeding and related techniques for matching the nitrogen supply in feed to animals’ specific protein requirements would decrease the total ammoniacal nitrogen in manure and may decrease feed costs.

Ammoniacal nitrogen (NH-N) is a measure commonly used for testing the quantity of ammonium ions, derived naturally from ammonia, and returned to ammonia via organic processes, in water or waste liquids.

Ammoniacal nitrogen (NH-N), is a measure for the amount of ammonia, a toxic pollutant often found in landfill leachate and in waste products, such as sewage, liquid manure and other liquid organic waste products.

It is based on total ammoniacal nitrogen (TAN), with TAN tracked from excretion to land application and will include aspects of feed nitrogen management, fertilizer sources and relationships with climatic variables such as temperature.

This is because leachates contain very high ammoniacal nitrogen concentrations, are usually very acidic, are often anoxic and, if received in large volumes relative to the incoming sewage flow, lack the Phosphorus needed to prevent nutrient starvation for the biological communities that perform the sewage treatment processes.

These characteristics, along with their fast growth, ease of larviculture, high fecundity and relatively high tolerance to both nitrate and ammonia, (particularly ammoniacal nitrogen, NH-N, which is typically more toxic than ammonium, as it can more easily diffuse across the gill membranes), makes this species ideal for aquaculture.

Many sewer undertakers limit maximum ammoniacal nitrogen concentration in their sewers to 250 mg/l to protect sewer maintenance workers, as the WHO's maximum occupational safety limit would be exceeded at above pH 9 to 10, which is often the highest pH allowed in sewer discharges.
