Ammonia Treatment
Fifty gallon per minute ammonia stripper installed at SMIC in China. 2000ppm in < 30 ppm out at 0 degrees C.
The ammonia stripper above is installed at
SMIC, a large semiconductor manufacturer, in Shanghai, China.
The system removes ammonia from the plants wastewater by stripping it
from the water and adsorbing it in ammonia sulfate brine. The semiconductor
manufacturing process uses ammonia in many processes, which result high
concentrations of ammonia in the plants wastewater. High ammonia concentrations
can cause depleted oxygen and algae blooms in rivers and lakes.
This system treats 50 gallons per minute and removes 98% of the ammonia
from the wastewater entering the system with and outside ambient temperatures
near zero Celsius.
