A camera washing device has an air pump, a wash water tank storing wash water, an injection nozzle with an injection part, a junction joint having a high-pressure air passage and a wash water passage, and an electromagnetic valve. The air pump generates and supplies high-pressure air to the high-pressure air passage. When the control part instructs the electromagnetic valve to be switched to an open state, the wash water and the high-pressure air are mixed in the junction joint to generate water particles. The generated water particles are supplied to the injection nozzle. When the electromagnetic valve is switched to the open state after injecting the high-pressure air only to a lens of a rear camera, the injection part injects the water particles to the lens of the camera.

A process for purifying glycerin recovered as a byproduct of biodiesel production comprises heating a glycerin effluent stream containing a low molecular weight alcohol, water and fatty acid esters of the low molecular weight alcohol to cause transesterification of the fatty acid esters to glycerides and additional low molecular weight alcohol. The reaction mixture is sparged with nitrogen to help remove water and low molecular weight alcohol, which drives the transesterification reaction towards glyceride formation. A wash water stream may also be added to the recovered glycerin stream from biodiesel production. Either before or following the transesterification reaction, an oil layer can be separated from the recovered glycerin stream by reducing the pH of the stream to below 7. Following separation of the oil layer and transesterification the glycerin stream is flash distilled to separate glycerin from water, salts, and glycerides.
