DAF Sludge Dewatering and Soild Separation

An South American Waste Treatment Service company sent information to us, GN Solids Control,  and looked for the exact solution for the DAF Sludge Treatment.

DAF, the full name is Dissolved air flotation, which can be widely used in sewage treatment, in the fields of industrial, manufacturing, oil & gas drilling, and marine waste water treatment.

DAF systems inject micro bubbles into the waste steam which attach to the solids and float them to the surface where they are skimmed off. However one of the more common issues with a DAF system is the mess associated and disposal cost and with handling the skimmed off waste solids.

For treating with the huge amount of Waste Solids, GN company offers reasonable solution to remove the Solid (suitable for discharge), and recollect the water and oil separately–Decanter Centrifuge plus Disc Centrifuge.

GN decanter centrifuge proves to be an effective and well proven equipment solution for dewatering the typically wet, sloppy solids skimmed off many DAF processes and wastewater systems.

GN supplies 250 sets of Decanter Centrifuges every year, with 70% purchased by the International Market, such USA, Canada, Holland, Australia, UK, Kuwait, Russia. It is 2 phase separation, for Solid and Liquid Separation.

 

After the solids being separated, if the client would like to recollect the high purified

Oil, Clean Water and separate the Fine Solids, GN suggest Disc Centrifuge. 

The Capacity can be from 1 m3/h to 15 m3/h, Bowl Speed reaches more than 6000 RPM.

Attention, the Solids Content of the feed material shall be 3% maximum.

Welcome to contact us, GN Solids Control, if you have problems with treating the DAF sludge. Our professional Technical Department would offer the exact solution based on your detailed requirement.

How to deal with the Water and Sludge after Flood?

One week ago, an Indian friend shared me some pictures and videos for the Flood in their country, and the terrible situation after Flood. The streets were full of sludge, and many parts of the city were still full or water.

It shall be a big headache for the local government to deal with the environment, besides the homeless people.

We, GN, a professional Chinese pump manufacturer for 11 years, we have two models of pump could be widely used to remove the sludge and water after flood.

The Centrifugal Pump and Sludge Vacuum Pump.

Today we would like to share detailed information about Sludge Vacuum Pump, the GN Hot Sale Pump!

VACUUM PUMP

 

Sludge Vacuum Pump

Waste vacuum pump, also named as solids transfer pump. With special structure design, it can be used at tough environmental for solids transfer, high working performance and less maintenance.
Waste vacuum pump, also named as solids transfer pump. It is a pneumatic slurry transfer vacuum pump for liquid,  slurry, and solids transfer. With special structure design, it can be used at tough environmental for solids  transfer, high working performance and less maintenance. The pump can transfer material with high gravity and high  density, solids content max. up to 80%.

How to Deal with the Boring Animal Excrement

Before there is a friend from India, we met each other in local exhibition, he said that he ran a Cow farm, with more than 50 cows. Every day the biggest problem for him is how to deal with the huge amount of excrement? He couldn’t find more space in his farm to bury these excrement? It is always  a big headache for him.

Then I suggested him, maybe he can consider about our product, Decanter Centrifuge, the hot sale separation from GN Solids Control.

This special and professional can easily separate the Solid and Water.

At first, he didn’ t believe it, then I show him an video, he was amazing and exciting.

You can find the video from the Linkage below, from our company (no advertisement) http://www.gnsolidscontrol.com/video/gn-animal-waste-treatment-decanter-centrifuge/default

We, Hebei GN Solids Control Co., Ltd, is a leading manufacturer based in China and USA, specialize in separation equipment, include industry decanter centrifuge, solids control equipment, waste management equipment, and shaker screens.GN was established in 2007,and GN is the first API certified solids control equipment manufacturer from China, and GN products have been exported to over 60 countries around the world.

 

 

 

How to deal with the boring Mud?

It is always a big headache for dealing with the Mud from our activity.

mud recovery system

GN Solids Control is an industry-leading manufacturer of solid state control equipment, established in Tangshan, China in 2007. Since then we have focused on quality and performance. After 11 years of hard work and network construction, we have become a very important player in the global industrial/oil and gas market.

Let us take a look at our mud drilling system today. It includes: 223 decanter centrifuge, 752 mud vibrating screen and other solids removal devices. The GN 223 Settling Centrifuge is designed for the diamond drilling industry. Here are some notable specifications for our 223 Centrifuge: The rotating bowl is made of duplex stainless steel – SS304. The discharge port is protected by a special ceramic blade for longer service life and better protection. The adjustable outlet makes the pond depth adjustment easier and faster. Pneumatically controlled springs will make the opening of the cover easier and safer. The bowl lift bracket can be used as a bearing for SKF production during transportation. The conveyor surface is made of tungsten carbide bricks for durability and ease of maintenance. Electrical components are from SIEMENS or SCHNEIDER. The GN 752 Mud Vibrating Screen is also produced for the diamond industry. The vibration mode is linear and the processing capacity is 200GPM. Adjustable G force up to 7.1G. The vibrator is manufactured by OLI or MARTIN and is ATEX, UL or IEC certified. Two screens are installed on the vibrating screen, which are pre-tensioned and of high quality. Electrical components are also made by SIEMENS or SCHNEIDER. By installing a hydrocyclone on the shale shaker, it can be adjusted to a slurry cleaner that separates the smaller solids to 20 microns.

This is a brief introduction to GN’s diamond drilling mud recovery system. Welcome to www.gnsolidsamerica.com, please send your questions to cris.zhang@gnsolidscontrol.com
