Czech Mate Against Ammonia | WaterWorld
Wastewater; Treatment; Czech Mate Against Ammonia. A review in the Czech Republic revealed high ammonia concentrations in the raw water feed of a new treatment plant. A novel method using nitrification bacteria immobilised in a PVA carrier was chosen for biochemical oxidation.
The original treatment plant was equipped with cage rotor aerators (Lakeside); these were upgraded in 1997. Two decades on — to meet increasingly stringent permit limits, serve a growing population and deal with the service plaza wastewater — the village replaced those aerators with larger Magna Rotor aerators (also Lakeside).

By Joe Nye. The discharge of ammonia from wastewater treatment plants (WWTPs) has become a challenging issue throughout the United States. Nearly half of all states – 24 states plus the District of Columbia -- have adopted new rules modifying how ammonia is measured pursuant to the EPA's 1999 water quality criteria, which address total ammonia rather than unionized ammonia and provide more
Multiphase Flow Simulation Guides Wastewater Treatment
T he humble Dommel River flows through the city of Eindhoven, the Netherlands, from the Belgian border in the south into the larger Maas River in the north. Along the way, it receives discharges from the Eindhoven Wastewater Treatment Plant (WWTP) as well as over 200 combined sewer overflows (CSOs) from 10 municipalities, handling approximately 170,000 cubic meters of water per day.
The estimation of Ammonia in effluents is generally carried out by Nessler’s method and is determined as Ammonical Nitrogen (NH 3-N) in ppm. Although ammonia is a naturally occurring compound and an essential macronutrient for plant growth, it is also toxic to aquatic life at higher concentrations.
