TBM is short for Tunnel Bored Machines, which are widely used for the large diameter tunneling, like the subway constructions, trans river projects and etc. In a TMB project, during tunneling, a great amount of slurry will be generated, and such slurry should be well treated before discharge. Here the treated mostly means the separating of solids and water, which is also called dewatering. In TBM slurry, comparing with slurries from oil and gas industry or HDD projects, there are much fewer che...

Decanter centrifuges are quite popular for separating out solids particles from liquid in many industries like drilling mud solids control, waste management, slurry treatment, food and beverage industry and waste water treatment. GN Solids Control is one of the leading professional solution providers among decanter centrifuge manufacturers. Just these days, GN Solids Control has finished fabrication of a decanter centrifuge system for a waste water separation project. This system includes a big...

In any modern city, there are municipal sewage and water pipelines crossing under the city ground. When there is need to lay a new pipeline or repair an existing one, there comes difficulty if we wouldn’t like to bring damage to the ones already there. Then, the brilliant human beings came up with the technology of hydro excavation, which is both highly reliable and accurate. It use high pressure water and a vacuum system to dig into the soil and is considered as a kind of surgical method....

In the Africa, there are lots of kinds of resources, including gold and black gold, the crude oil. The wise African governments have foreseen the by-products of the crude oil explorations which have already happened in some other countries, the environmental problems. That’s why, along with the crude oil exploration drilling rigs, all rigs are requested to have a drilling waste management systems, especially for the drilling cuttings before disposal. Talking about drilling cuttings, the...

GN Solids Control has spent years on decanter centrifuge research and development, and decanter centrifuges are quite popular in different industries to serve different roles, including the oil and gas drilling waste treatment, the barite recovery in a solids control system, for oily sludge treatment and also for beverage and food industry. And in a recent project, clients are using a small model of GN decanter centrifuges together with dewatering units. This project is for a European client. ...

As the rapid recovery of China from the global pandemic situation, the economy is gradually booming up and also the various industries. Recently, a domestic client in Tianjin purchased a separation set of machines, including a GNLW454ET decanter centrifuge and a GNSD90 three phase disc stack separator. 1. GN Decanter Centrifuges. Decanter centrifuges are always quite efficient in separation works for solids and liquid separating. For different treating capacities, GN put to market centrifuge ...

Drilling mud is one kind of liquid containing different components, only when the proportions of each component are correct, the drilling mud could be effective and useful. That's’ why besides the solids removal for the drilling mud, there should be a mud mixing unit to work along with the mud tank for compensating the chemical loss for the drilling mud. A complete mud mixing unit should contain following items: 1. A mud mixing hopper. It is a Venturi hopper, when linked to a feeding p...

By end of year 2020, GN Solids Control has another set of mud system ready for delivery for a domestic engineering company in China. It is a high configuration mud system. Including following: 1. Mud recycling system: GNMS-1000D and GNMS-500D are two models of GN compact mud systems, which are also quite popular. The complete system is designed on one skid, combined by a double deck shaker. The mud to be treated will be transferred by a pump to the lower deck shaker, and the lower deck shaker...

As one of the leading brands for separation solution providing, GN Solids Control has been giving equipment and solutions to many companies in different industries, including the environmental protection companies. By end of last year, GN Solids Control has fabricated a vibration screen unit for this company. 1. What is a vibration screen?In all solids and liquid separation works, there should be a vibration screen unit as the 1st step separation. It is pure physical separation, but the most ...

Mud cleaner and drilling fluids centrifuge are 2 of the core equipment in a complete drilling fluids separation procedure. A mud cleaner is a combination of desanding cones and desilter cones, respectively for separation of particles bigger than 40 microns and 20 microns. And a decanter centrifuge is used for even finer particles with sizes ranging from 2 to 5 microns. GN Solids Control is one of most well-known brands in the world for the drilling fluids equipment and system, who is professi...
