A chemical dosing optimization apparatus includes a chemical dosing optimization part and a chemical dosing output control part, wherein the chemical dosing optimization part receives real-time data at least from a water treatment plant treating feed water by dosing a chemical and providing a treated water, analyzes the real-time data through a water treatment model in response to receiving the real-time data, derives a prediction value for predicting a state of the treated water of the water treatment plant, and derives a control value based on the prediction value through a controller, such that the control value is to set a minimum of a chemical dosage to be dosed in the feed water while the state of the treated water of the water treatment plant is maintained in a normal range, and wherein the chemical dosing output control part provides the control value to a water treatment control device.

Chemical dosing optimization apparatus and method for water treatment plant

A plant monitoring method using exergy efficiency is provided. The plant monitoring method includes detecting data associated with chemical exergy and physical exergy of each apparatus or subsystem and obtaining a chemical exergy value and a physical exergy value of each apparatus or subsystem, calculating an exergy efficiency value of each apparatus or subsystem on the basis of the detected data, and identifying a maintenance target which refers to an apparatus or subsystem that needs to be improved in efficiency on the basis of data obtained through the calculating of the exergy efficiency value.

Plant monitoring method using exergy efficiency value

An apparatus for controlling output in a water treatment plant treating water includes: a chemical dosing management part configured to analyze real-time data to determine a control mode of chemical dosing optimization, and provide the determined control mode as a management command; a chemical dosing optimization part configured to analyze the real-time data to derive a control value such that the control value is to set a minimum of a chemical dosage to be dose in the water while a state of treated water of the water treatment plant is maintained in a normal range; and a chemical dosing output control part configured to provide the control value to a water treatment control device for controlling the water treatment plant, according to the control mode of the management command.

A cooking appliance capable of preventing a user's unintended rotation of a knob assembly includes: a main body including a control panel; a valve positioned inside the main body, and including a valve shaft being pushable and rotatable; and a knob assembly including an inner knob coupled with the valve shaft, and an outer knob being movable with respect to the inner knob in a first direction in which the outer knob approaches the inner knob, wherein, when the outer knob moves by a first push distance in the first direction, the valve shaft and the inner knob are prevented from rotating.

Cooking appliance

A household appliance including a control panel includes a body and a control panel provided on an outer side of the body, wherein the control panel includes a first panel formed by a process of extrusion of an aluminum (Al) material and provided with at least one surface thereof exposed to an outside thereof, and a second panel provided to be coupled to the first panel and made of the same material as the first panel.

Control panel and household appliance having the same

Disclosed are a water treatment apparatus using underwater plasma discharge and a water treatment system using the same. The apparatus includes a reactor having an inlet through which raw water flows in and an outlet through which purified water flows out, a ground electrode provided at a first side of the reactor, and a plasma electrode module provided at a second side of the reactor and configured to generate plasma. With plasma generated through underwater discharge, it is possible to decompose or remove organic substances and microorganisms present in raw water.

Water treatment apparatus using underwater plasma discharge and water treatment system including same

A home appliance having a support device configured to prevent the home appliance from falling. A home appliance includes a body having an openable front surface, and a support device having a bracket configured to be coupled to the body, and a foot configured to support the body by being coupled to the bracket, wherein the foot is provided such that a point of support supporting the body by making contact with the ground, is formed in one end portion of the foot.

Home appliance

A cooking appliance including a cooking room; and a rack assembly removably installed in the inside of the cooking room. The rack assembly includes a stationary member fixed in the inside of the cooking room; a moving member configured to slide out of the cooking room; a locking device installed in the stationary member, and configured to lock the stationary member to prevent the stationary member from escaping from the inside of the cooking room; and a noise reducing member configured to reduce noise that is generated when the locking device contacts with at least one of the stationary member and the moving member.
