In the separation of liquid or solid mixes with a high solids content, a decanter centrifuge is the ideal solution. Unlike chamber filter presses, the decanter centrifuge run continuously. The solid particles which are finely distributed is separated from the suspension through robust centrifugal forces.
Decanter is beneficial in various sectors all across the globe. Decanter centrifuge is ideally utilized for specific applications, such as sludge dewatering, wet classification, and sorting of solids.
Understanding Decanter Centrifuge
A decanter centrifuge is a machine utilized to separate solid and liquid via a constant and high-speed rotating process. While biosolids wastewater treatment is a key application, the separation of a solid material from a liquid in a slurry is also essential for numerous sectors such as chemical, wastewater treatment, oil & gas, petrochemical, and pharmaceutical.
It works on the gravitational force principle. Constant rotating generates a force of gravity between 1000–4000 times the normal G’s, eventually decreasing the time of separation to minutes from hours. A decanter centrifuge looks like a bowl tube that rotates at an extremely high speed.
The bowl tube is connected to an internal conveyor, which travels in a similar direction but at a dissimilar velocity, leading to the removal of solid from the centrifuge.
Types of Decanter Centrifuge
Two-Phase Decanter
Two-phased decanter centrifuge is extensively utilized in numerous sectors such as oil & gas drilling, waste management, manufacturing, hemp, and food processing, to separate solid and liquid.
Three-Phase Decanter
Three-phase decanter is mainly utilized when three components are present, two liquids and one solid of different densities, which required separation from the solid component. The main quality of a three-phase decanter is the constant separation of three phases in one operation, which is extremely important in various processes across industries, eventually leading to efficiency and time-saving.
Increasing Utilization of Decanter Centrifuge in the Oil & Gas Sector
The rising oil & gas sector is a key reason boosting the requirement for decanter centrifuges, as this sector relied on decanter centrifuges for numerous applications, for instance, dewatering of sludge, oil recovery, and drilling mud separation.
Moreover, governments are instructing sustainable development all across the globe as a result of which stringent environmental rules are being executed. This has also increased the requirement for solutions to effectively treat wastewater, and decanter centrifuges play a key role in decreasing pollutants, meeting mandatory discharge standards, and separating solids from wastewater.
Additionally, with advancements in technology, decanter centrifuge is gaining significant popularity. The mounting requirement for decanter centrifuges has resulted in innovations in this field, leading to decreased consumption of energy, advanced automation by utilizing IoT sensors, and improved separation efficiency.
With the existence of stringent regulatory standards to safeguard product quality, surging utilization in various sectors, as well as the advancement in technology, the requirement for decanter centrifuges will continue to surge, and it will reach a value of USD 2,561.1 million by the end of this decade.
