A container such as a barrel or drum is provided for processing of solid material or parts with a liquid. The container is designed with grooves leading to holes or slots in the side that draw liquid into the container due to the rotation of the container when it is immersed in a tank of liquid. The holes or slots have a small dimension in the direction of rotation to minimize the probability of solid material coming out of the container. The fluid flow caused by the rotation serves to increase the rate of solution replacement inside the container as well as to keep the solid material from falling out through the holes or slots. The container disclosed is useful in processes in the plating, etching, leaching, and surface finishing industries.
