ABSTRACT:
A liquid supply apparatus capable of removing micro-bubbles and particles is described, including a pipe, a laser provider and at least one micro-bubble/particle outlet. The laser provider provides a laser crossing the pipe, wherein the laser is provided in a manner such that a micro-bubble/particle blocking/repelling barrier is formed crossing the pipe blocking or repelling micro-bubbles, particles or both in the liquid in the pipe. The micro-bubble/particle outlet is disposed on the pipe between the barrier and the liquid inlet of the pipe, adjacent to the barrier for discharging micro-bubbles, particles or both.
