Factory wastewater is included in industrial wastewater in a broad sense, and these various wastewater (hereinafter, wastewater) (Collectively referred to as) is a cause of water pollution and soil pollution when discharged without processing contaminants.

Therefore, most of the wastewater is discharged into clean water after treating pollutants using a wastewater treatment device using a flotation tank, a sedimentation tank, and a water separator in a wastewater treatment plant.

The wastewater treatment device using the floating tank is a solid/liquid separation device that causes foreign substances lighter than water to float to the upper portion of the treatment tank while horizontally flowing the wastewater introduced through the wastewater inlet, and collects and removes the injured foreign substances into the floating sludge collector. to be.

The wastewater treatment device using the sedimentation tank is a solid/liquid separation device for sedimenting and removing substances having a specific gravity greater than water from the wastewater to the bottom of the treatment tank.

The wastewater treatment device using the oil-water separator is a device that separates water from the water by using the self-floating force of a material that is lighter than water and naturally floats in the wastewater.

The wastewater treatment system using the floating tank and sedimentation tank is manufactured and installed according to the nature of the incoming wastewater. Wherever the nature or condition of the wastewater changes frequently depending on the season and the production material, it is possible to cross-use or use mixed operation. It is installed as a structured water treatment device.
