Fouling resistance in concentrating TCM extract by direct contact membrane distillation

This study investigates the transport resistance of fouling layer formed during concentrating the extract of traditional Chinese medicine (TCM) by direct contact membrane distillation (DCMD). Empirical equations for calculating the physical properties of TCM extract were combined with the heat transfer equations of DCMD to describe the concentrating process. These equations were solved through an iterative computer program to obtain the thermal...
