GN Decanter Centrifuge and Disc Centrifuge for Fermentation Liquid Separation

One our Canada client asked give out solution for the fermentation liquid separation. This fermentation is from animal manure, client want us remove out the solids as much as possible. It is different with other separation project ,because the solids content is small.

According to the data sheet of material, the solids content is less than 5%, and the most of the particle is smaller than 75um. As usually we will suggest client to add flocculant chemical to material to combine the tiny solids into bigger ,and then feed it into decanter centrifuge. But in this project, it is forbidden to add any chemical medicine. That is the biggest challenge in this project. One other challenge is the flow rate is 25m3/Hour.

In this kind project, 2 phase disc centrifuge is the best optional, but due to the huge treating capacity, we need to use several sets disc centrifuge as it treating capacity is only 8m3/Hour. That will increase the cost of equipment. After discuss with engineer, firstly we will feed the material into decanter centrifuge to reduce the solids content as much as possible, and then feed the liquid into disc centrifuge. The lower concentration liquid will improve the separation capacity of disc centrifuge.
In this project, client have no requirement to the dryness of discharged solids, so we do not need extra dryer facility for further treatment. because the discharged solids from disc centrifuge is very wet, it through the flush water to discharge solids. Different with disc centrifuge ,the discharged solid from Decanter centrifuge is very drey,but the liquid is not as clean as disc centrifuge.
GN Decanter treating capacity from 6 cube meter to 120 cube meter with vary model ,and the disc centrifuge capacity is between 1 cube meter to 25 cube meter. All these capacity is calculated when treat the clean water. We almost can satisfied all the project demanded. If you have demanded on these equipment, welcome to contact us .
