GN Liquid Manure Decanter Centrifuge Introduction

1. What is a Liquid manure Decanter Centrifuge used for?

1.1 We all know that liquid manure is valuable. It contains elements that are essential for plant growth up. However, large quantities of these can become a problem. High phosphate and nitrogen content makes storage and processing difficult. In order to sovle this disposal problem, we raised the answer separation.

1.2 In the breeding farms produces large quantities of liquid manure. In order to avoid accident hazards such as suffocation or drowning, operators must comply with numerous safety regulations. In addition, there is the high odor and particulate pollution.

1.3 Before the separation process, a special flocculant consisting of bentonite and starch is added to the liquid manure. The separation takes place from GN SEPARATION high performance decanter. Through the combination of flocculant and high-performance decanter, the separation system achieves a dry solids content of over 30 percent.

Due to its high centrifugal acceleration about round. 2,500-5,000 rpm, the decanter efficiently separates the solids in the liquid manure from the liquid phase.

1.4 Because the suspended particles have a higher density, they collect on the bowl wall. The scroll conveyor transports the solids continuously to the discharge. The liquid phase flows off as process water along the scroll.

2. GN Liquid manure Decanter Centrifuge Features

2.1 One of the special feature is the highly efficient separation of phosphate: up to 99 percent phosphate is bound in the solids. For nitrogen, the liquid manure separation rates are over 60 percent dairy cattle and over 40 percent pig respectively.

2.2 The special designed separation processes for liquid manure, usually do not bind enough of the nutrients in the dry solids. Consequently, the concentration in the remaining liquid manure is still too high. The decanter separation system, offers a solution that is both efficient and saving energy . Because of the proven centrifugal technology, the system achieves particularly high separation efficiencies for phosphate and nitrogen.

2.3 The solids extracted by separation are odorless. Safe and simple storage. The unique added value comes from the fact that the solids can be pelletized and resold, for example as garden fertilizer or spreadable fertilizer for horticultural businesses and garden markets.The water is ideal for irrigating hops and asparagus by sprinkling. It is also suitable for irrigating crops , thus contributing to the sustainable soil improvement.
