The "Powdered Activated Carbon Automatic Supply Machine" is a simple yet reliable supply device that uses powdered activated carbon with a moisture content of 50% and automatically supplies a constant required amount continuously. It is equipped with a rotatable rake to prevent the very poorly flowing powdered activated carbon in the hopper from solidifying, compacting, or forming bridges. Additionally, there is a powdered activated carbon supply device at the bottom of the hopper, which supplies the powdered activated carbon, drawn in by the rake, in a sheet form through the clearance of a pair of metering rotors. The powdered activated carbon that adheres to the surface of the metering rotors of the supply device is removed by a scraper, allowing for smooth supply of the powdered activated carbon. 【Features】 ■ A device that supplies powdered activated carbon with a moisture content of 50% ■ Equipped with a rotatable rake to prevent the formation of bridges ■ Supplies powdered activated carbon in a sheet form through the clearance of a pair of metering rotors ■ Powdered activated carbon adhering to the surface of the metering rotors is removed by a scraper *For more details, please refer to the PDF document or feel free to contact us.

At water treatment plants, the removal of unpleasant odors and harmful substances contained in raw water is essential for supplying safe drinking water. Particularly, depending on the condition of the water source, odor components can affect water quality, potentially causing consumer discomfort and health concerns. Powdered activated carbon is known to be an effective means of adsorbing these odor components and chemicals, thereby improving water quality. Our "Powdered Activated Carbon Automatic Supply System" stably supplies powdered activated carbon with 50% moisture content, supporting the removal of odors in water treatment processes. 【Usage Scenarios】 - Raw water treatment at water treatment plants - Advanced water treatment - Water treatment processes requiring odor control 【Benefits of Implementation】 - Improvement of water quality through the removal of odor components - Supply of safe and delicious water - Enhanced reliability of water treatment plants

At wastewater treatment plants, the generation of odors from sludge is a significant challenge. Odors can not only impact the surrounding environment but also adversely affect the health of workers. As a countermeasure against odors, deodorization using powdered activated carbon is effective, but it is crucial to stably supply the appropriate amount of activated carbon. Our "Powdered Activated Carbon Automatic Supply System" provides a stable supply of powdered activated carbon with 50% moisture content, supporting odor control. 【Usage Scenarios】 - Sludge dewatering process - Aeration tank - Final discharge tank 【Benefits of Implementation】 - Odor suppression through the adsorption of odor components - Improvement of water quality - Enhancement of the working environment
