Abstract

Disclosed is a method for treating water containing organics. The method includes treating water containing organics with an adsorbent, and adding zero-valent iron to the water in the presence of oxygen and adding persulfate thereto, wherein the water is oxidized using reactive oxygen species containing hydroxyl radicals and superoxide radicals produced by the addition of zero-valent iron and persulfate radicals produced from persulfate activated by the addition of zero-valent iron. According to the treatment method, non-biodegradable organics as well as nitrogen and phosphorous, nutrient salts which could not readily be removed by conventional treatment methods, contained in water to be treated, can be effectively removed by a physical removal method using activated carbon and by a chemical removal method using radical oxidation.

Abstract

There are provided a valve control system, a bidet using the same, and a valve control method. The valve control system includes a latch valve controlling a stream of water in a pipe; a flow rate sensor measuring a flow rate in the pipe; and a valve control device controlling the operation of the latch valve. The valve control device determines whether or not the latch valve is malfunctioning upon analyzing a flow rate measured by the flow rate sensor. When the latch valve is malfunctioning, the valve control device controls the latch valve to re-operate.

Abstract

A channel switch valve module including a single position detection sensor according to the present invention includes: a valve drive gear including a barrier having a plurality of position confirmation ports; and a single position detection sensor disposed at one side of the valve drive gear and detecting the position of the valve drive gear. The position detection sensor determines whether the position detection sensor operates normally based on whether light components are transmitted or received through the position confirmation port. The method of the present invention includes first confirming the component reliability of the position detection sensor by recognizing whether the position detection sensor is operating normally through an on/off process of the position detection sensor before a valve drive gear is driven to rotate. When a channel switch valve module operates abnormally through the above process, it is easy to confirm which component from among the valve drive gear and the position detection sensor is operating abnormally. As a result, accurate switching of the valve drive gear becomes possible.

Abstract

There is provided a cold water tank including: a first tank having an inlet pipe through which water to be cooled is introduced; and a second tank provided in the interior of the first tank such that water of the first tank can be introduced thereinto, having an evaporator included in a refrigerating cycle to cool the introduced water, and having an outlet pipe through which cooled water flows. Although water is introduced at high pressure, the introduced water can remain in the cold water tank for a period of time required for being cooled, and although water is introduced at high pressure, the introduced water can be in a stable state in the cold water tank. Thus, water can be cooled with its inflow pressure maintained, and the degree of freedom of a faucet or cock for allowing cold water to flow therethrough can be improved in its height.

Abstract

Disclosed is an air purifier able to maintain the normal state of drive of a disk-shaped humidification filter by controlling the state of rotation of the humidification filter. The air purifier comprises: a water tank which accommodates water on the inside and is provided with a rotational shaft to which the humidification filter is attached; a drive source which is connected to the rotational shaft and causes the rotational shaft to rotate; a detection unit which is provided on the water tank so as to detect the state of drive of the humidification filter; and a control unit which is connected to the detection unit and the drive source and controls the state of drive of the drive source in accordance with a signal from the detection unit. The air purifier can maintain the normal state of drive of the humidification filter by using a stepping motor and the control unit in order to vary the state of rotation of the humidification filter and thereby remove extraneous material when the humidification filter is rotating abnormally due to extraneous material.
