Pretreatment an overview ScienceDirect Topics

For most of the raw materials, the pretreatment conditions resulting in the highest glucose yield differ from those yielding the maximum yield of xylose. This would suggest a two-stage pretreatment, such as using steam, in which the first stage is performed at low severity to hydrolyze the hemicellulose, and the second stage at a higher degree

water purification Description, Processes, & Importance

Pretreatment. In pretreatment, biological contaminants, chemicals, and other materials are removed from water. The first step in that process is screening, which removes large debris such as sticks and trash from the water to be treated. Screening is generally used when purifying surface water such as that from lakes and rivers.
