The invention relates to a new method for using an oxygen pipeline and a spherical tank. The method comprises the following steps of: in the first step of using a new oxygen pipeline 2, opening V4 to introduce nitrogen into the new oxygen pipeline 2, blowing the new oxygen pipeline 2, ...
A computer-aided gas analyzing system with a zirconia oxygen pump-gauge was developed and used to measure a small amount of reducing gas in a flowing inert gas. The flowing Ar containing CO or CH 4 was automatically titrated with oxygen by scanning the current of the oxygen pump; on-line ...

The present invention relates to a burner using plasma, which uses a mixture fuel in which water and industrial waste oil are mixed at an appropriate ratio. A combustion tank has a positive electrode (+), a rod installed at one side of the combustion tank has a negative electrode (-), ...
Porcine epithelial cells were cultivated on microspheres with an average diameter of 35 μm in a stirred tank bioreactor for virus production. The oxygen uptake rate (OUR) was determined on-line by a dynamic method. This on-line measurement was used to estimate glucose consumption rate for perfu...
Septic tankExcrementOdour, which is emitted from septic tanks treating excrement and manure, has become public concerns. Reduced sulphur compounds, such as hydrogen sulphide, are the main sources of the malodour, and readily degradable organics play an important role in the production of the ...
The concentration of dissolved oxygen (DO) in the aeration tank(s) of an activated sludge system is one of the most important process control parameters. The DO concentration in the aeration tank(s) is maintained at a desired level by using a Proportional-Integral-Derivative (PID) controller....
CONSTITUTION: A fuel cell device of a submarine using hydrogen peroxide dissolution comprises a hydrogen peroxide storage tank(110), a reactor(120), an oxygen storage unit(160), and a fuel battery(170). The hydrogen peroxide storage tank is connected to the hydrogen peroxide storage tank, and...
An activated sludge collected from the denitrifying tank of a municipal wastewater treatment plant (Cassino, Italy) was used as inoculum (10% v/v) in the batch bioassays. The biogenic S0-based denitrifying bacterial cultures were enriched for 3.5 months in 125 ml serum bottles with a ...
