GN Solids Control has been working on manufacturing decanter centrifuges for many years. With the fast development, more and more customers are willing to choose GN decanter centrifuges, now GN Solids Control customers are widely in more than 70 countries.
Every year, GN Solids Control manufactures more than 300 sets decanter centrifuges. As decanter centrifuges are popular treating equipment which can be used in various solids and liquid separation area, now GN Solids Control decanter centrifuges are working in oil and gas drilling slurry separation, mining slurry treating, HDD slurry treating, diamond drilling slurry treating etc.
Every year, we receive hundreds of inquiries on decanter centrifuges. Here is one example we would like to share with you (sent by one prospect):
We specialize in supplying waste water treatment equipment in water and waste water treatment
Can you quote Decanter machine as below?
Capacity (max.): Capacity: 100 – 120m3/hr; 1000 – 2000 kg DS/hr
Bio-sludge, concentration 2% (bio sludge in thickener basin in Municipal waste water treatment system)
Type of waste water: Municipal WWTP
This project, customer would like to use new decanter to replace old one (Japanese product).
Our competitor is Alfa Laval, main driving: 160kw 3 phase x380Vx50Hz, and sub motor: 37kW including variable frequency each motor.
Some specification for detail below:
1/ Dry sludge: ≥ 28%.
2/ Screw: 1.4408 or AISI 316Ti
3/ Drum: SS Duplex or 1.4463
4/ Variable frequency for each drive
5/ supervisor instrument control vibration, bearing etc.
6/ Control panel with HMI (Siemens S7)
GN Solids usually don’t provide 3 phase treating decanter centrifuge as the working efficiency is pretty slow. And the price of GN decanter centrifuge is almost 3 times of one 2 phase centrifuge. Actually, most customers will still need one 2 phase coarse centrifuge in the front. So there we recommend our customer to use 2 sets GNLW553-VFD (22inch rotating bowl): coarse centrifuge and polish centrifuge. Just need to add another oil and water separator. So the whole treating system is more cost-effective.
