Abstract: The Russian Federation has huge reserves of lake sapropel. There are about 50 thousand deposits in our country, and the identified reserves amount to more than 200 billion cubic meters of natural humidity (92-98%).
The greatest use of sapropel is in agriculture as natural fertilizers, and is also actively used in construction, medicine, chemical industry, etc. The need to develop sapropel deposits is also due to the natural processes of silting lakes. So, extracting lake sapropel, we get environmentally friendly raw materials and provide cleaning of reservoirs, which are sources of fresh water and recreational facilities.
The main reason for the limited use of sapropel is its high natural humidity. Having a fine colloidal structure, sapropel is practically not filtered, so the processes of its dehydration in natural conditions are labor-intensive, and attempts to artificially remove moisture are energy – consuming.
This paper presents the analysis of existing shop and field methods and technical solutions for sapropel de-watering.
