Existing methods of dehydration of sapropel

Abstract

The Russian Federation has large reserves of lake sapropel. In Russia, there are about 50 thousand deposits of sapropel of natural humidity. Sapropel is used in various fields: medicine, construction, animal husbandry and agriculture. So, extracting sapropel, we get not only environmentally friendly raw materials, but also clean lakes that are sources of fresh water and recreational activity. In order to use sapropel, it is necessary to lower its moisture. Difficulties associated with dehydration of sapropel arise due to the high natural humidity of sapropel, which reaches 98 %, as well as due to the fact that sapropel has a fine colloidal structure. This article presents the analysis of existing methods and engineering solutions for sapropel dewatering.
