Abstract: PURPOSE: A rotating flotation system for treating the wastewater containing hydrophobic emulsions such as cutting oil is provided. This system is characterized in that the wastewater containing foaming agents rotates in the circular tank without coagulant and the hydrophobic emulsions adhered to air bubbles float and are removed by a skimmer. Because the skimmer rotates slowly at about 0.5rpm, the floated scum with pollutants is not broken easily. CONSTITUTION: The rotating flotation system is characterized by comprising the following parts of: recirculated water(1), wastewater(20) containing fine air bubbles, a circular flotation tank(21), an inner tank(22), an upper tank(23) for storing clarified effluent, an inlet(24) for clarified effluent, a conic settling tank(25) to remove sediments without scraper, a strainer(26), a skimmer(27) to remove scum, a pipe for removing scum(28), a water-level control valve(29), and an outlet(30) for clarified effluent. This system allows enhenced contact between the wastewater containing oily pollutants and a hydrophobic foaming agent such as methyl isobutyl ketone(MIBK) by generating viscous air bubbles which oily pollutants easily adhere to. Consequently, oily pollutants are separated from wastewater easily, and the removal efficiency is improved.

The power amplification stage(320) includes the first power amplifier(322) for amplifying the output of the modulator(310) to an intermediate power level and the second power amplifier(324) for amplifying the output of the first power amplifier(322) until it reaches a pre-set RF output power level. The RF coupler(330) transmits a part of the RF output signal to the antenna and transmits a different part of the RF output signal to an adjacent channel power monitoring circuit(350). The adjacent channel power monitoring circuit(350) receives the RF output signal from the RF coupler(330) and outputs an intermediate frequency measurement signal to a mobile switching center. The adjacent channel power monitoring circuit(350) includes an RF mixer(355), a low pass filter(350), a high pass filter(365), power detectors(370, 375) and an input/output interface circuit(380). The RF mixer(355) mixes an RF carrier of 1930 to 1990 MHz outputted from the transmission local oscillator(315) and down-converts the RF output signal to restore a baseband characteristic of the original inphase signal and a planimetric signal. The low pass filter(360) and the high pass filter(365) filter an adjacent channel noise signal outputted from the RF mixer(355) to obtain a signal required for measuring an adjacent channel power. The input/output interface circuit(380) receives the power level output provided form the power detectors(370,375) and computes a power ratio of an unnecessary distortion signal and a signal factor desired to be obtained.
