SOLID-LIQUID SEPARATION DEVICE, SOLID-LIQUID SEPARATION METHOD, WATER QUALITY MEASUREMENT DEVICE, AND WATER QUALITY MEASUREMENT METHOD

摘要

Provided are a solid-liquid separation device and solid-liquid separation method with excellent ability to separate particles, which have a density close to that of a fluid, from a fluid. A solid-liquid separation device (1) has a curved channel (10) as a separation means for separating, from a liquid to be processed that contains solid particles, a concentrated liquid that contains the solid particles and a processed liquid. The curved channel (10) has a flow channel including a wall surface with a curvature, and a portion of the inner wall surface of the flow channel is a slipping wall surface.
