The application of manure treated by decanter centrifuge

The first use of manure for electricity generation is relatively mature technology. Use cow dung to generate electricity and make substitutes for biogas and coal. For example, in dairy farms, the annual electricity generated by the fermentation of dried cow manure processed by a cow manure Decanter centrifuge can save 1.2 million yuan in electricity costs. In addition, cow dung sticks and cow dung honeycomb coal can also be developed in a certain place. Cow dung sticks made of cow dung are used as fuel, and the combustion value is high. Cow dung honeycomb coal is compressed with cow dung and coal at a ratio of 4:6, which solves the problem of honeycomb coal. Pollution of the atmosphere.

Feces can also grow Agaricus bisporus and straw mushrooms. The cow dung produced by the milk buffalo is used for biogas power generation. The produced biogas slurry can be made into liquid fertilizer, and the fertilizer is sold for more than 3,000 yuan a ton. The milk produced by milk buffalo is about 4 yuan, but the fertilizer can sell for 100 yuan. This shows that the use of cow dung can not only increase the economic income of cattle farmers, but also bring many economic and social benefits. In order to solve the problem of farming wastewater pollution and build an environment-friendly farming base, the company’s leaders attach great importance to pollution control work, and entrusted our unit to design a plan for the fecal sewage solid-liquid separation treatment project. In order to complete this work with high quality, the decanter centrifuge

The dried cow dung dehydrated by the cow manure Decanter centrifuge can also be used as feed for many animals. The cow manure contains minerals and various nutrients, including organic matter, total nitrogen, crude protein and other nutrients. This is Cow dung is a prerequisite for feed. For example, the cow dung of a cow used to raise earthworms can finally obtain an economic value of about 2400 yuan

After the manure is processed by the decanter centrifuge, according to the similar project investigation and the information provided by the owner, the sewage mainly comes from cow urine and ground washing wastewater, and contains manure and urine.

According to the requirements of the owner, it is necessary to treat about 300 tons of manure sewage produced by 4000 cows every day, and the moisture content of the dried cow manure after treatment is about 60%-70%. The excrement processed by the decanter centrifuge can greatly increase the income of the enterprise, and truly turn waste into treasure.

GN Decanter Centrifuge for sludge dewatering projects in Africa sewage treatment plant

News from GN company this week: Recently, 1 complete set of GN decanter centrifuge for sludge dewatering projectst have been manufactured and ready to start serving a Africa sewage treatment plant. Including 1 set of 2 Phase decanter centrifuge GNLW364ET-VFD and 1 set of control panel.

To make sure the Decanter Centrifuge System will provide a reliable performance and the parts and components of all the equipment will run smoothly for a long term operation, our technical department, production department and quality control department have paid a lot of attention to the material selection, material preparation, every step of production and the inspection for this set of equipment in each step.

If you need any support about the operation and maintenance of the equipment of Decanter Centrifuge System such as decanter centrifuge, Chemical dosing unit and mud tanks, please feel free to contact GN company for our engineers’ best experience and knowledge in the relevant industry. We will do our best to assist your project because just in this way we can establish a stable and long term cooperation. And we can provide on-line support and site instruction for specific situation if needed.

As a leading manufacturer of separation equipment and conveying equipment, GN always pay high attention to the product quality and consider the long-term benefits for our users. We would also like to introduce GN as a professional manufacturer in decanter centrifuge field, GN pays a lot of attention in the selection of raw materials, high-quality centrifugal casting or forging stainless steel materials are used, and for wearing parts, hard alloy protection is used.

GN high-end CNC lathes, CNC centers, and CNC gantry milling machines can better ensure the machining accuracy of centrifuge parts. In terms of the dynamic balance of the decanter centrifuge, in addition to the ordinary low and medium speed dynamic balance, GN also applies a high speed dynamic balance process, which can dynamically balance the centrifuge screw and bowl at the actual working speed of the centrifuge. In terms of market applications, GN decanter centrifuges are widely used in the industry, and the products are exported to more than 60 countries and regions in the world, and have won high praise from customers.

Decanter centrifuge application in the paper industry

Sewage and sludge in the paper industry need to be treated in a sludge thickening tank. Now the main sludge treatment process is: pre-dehydration, dewatering of decanter centrifuge, crawler dehydration. After the sludge concentration is increased, the dewatering efficiency of the decanter centrifuge will increase accordingly. But it should be avoided that the sludge concentration becomes too high, which will cause the sludge transportation pipeline to block the concentration is too low.

The papermaking wastewater mainly comes from the two production processes of pulping and papermaking in the paper industry. Both processes discharge large amounts of wastewater. The wastewater from pulping is the most polluted. The waste water discharged during washing is black-brown, which is called black water. The concentration of pollutants in black water is very high, BOD is as high as 5-40g / L, and it contains a lot of fibers, inorganic salts and pigments.

The process of the decanter centrifuge to deal with the papermaking sewage is to make the sludge pass through the gravity dehydration zone, then to the pressure dehydration zone, and finally to the pressurized dehydration zone. After these three steps, a relatively dry mud cake is produced. The concentration suitable for dehydration is generally about 10%.

The decanter centrifuge has the advantages of low investment, automatic control, continuous operation, low energy consumption, high dehydration efficiency, easy management, low maintenance cost, low noise, and low dosage of chemical agents. Therefore, dewatering decanter centrifuges are recommended for papermaking wastewater and mud dewatering projects.

GN dewatering decanter centrifuge is E series decanter centrifuge with beach angle of 8.5 degrees. GN E series decanter centrifuge is usually used dewatering and thickening purpose. It is widely used for maximum dewatering requirements of municipal and industrial wastewater sludge. The dewatering decanter centrifuge is designed for easy separation material include large particle size, high density difference of solid and liquid, low viscosity, high concentration, high treatment capacity and higher dryness than clarity. The materials like sludge or wastewater containing fine particles usually need to be added with flocculants to gather the fine particles condensed into large ones, and then dewatered with E series decanter centrifuge.
