Decanter centrifuge manufacturer and supplier 2024: The activated sludge flocs are slightly refined, with abnormal color, poor settling performance, turbid supernatant, and many small feathery sludge fragments; 2. Microscopic examination can reveal protozoa, but their numbers have sharply decreased. During the microscopic examination process, protozoa were found, but most of them have died or lost their activity; Under the microscope, the volume of sludge flocs is smaller and scattered than usual; 3. The sludge in the sedimentation tank floats in a cloud like manner, resulting in severe mud leakage from the effluent; 4. The final effluent quality is turbid, and the COD detection index is far higher than the normal fluctuation range; First, let’s understand the process of sewage treatment. Kitchen and restaurant sewage first enters the oil separator to remove large particles and floating oil before entering the regulating tank. Automatic grid: Set up a grid to remove large particulate matter and impurities in sewage, ensuring the continuous operation of subsequent treatment devices. The grid residue is regularly manually treated. After removing the floating debris, the sewage enters the regulating tank. A submersible sewage pump is installed in the regulating tank to lift the sewage, and a mixing system is set up in the regulating tank for stirring to prevent sediment.

The fundamental principles of operation for the 2 phase decanter centrifuge and 3-phase Shenzhou Machinery decanter centrifuges are identical to those of the horizontal decanter centrifuge. To separate substances with different densities, the equipment uses a high-speed rotating assembly to create an acceleration inside the bowl that is thousands of times stronger than gravity. Then, the relative motion between the bowl and the screw is generated by the differential gearbox, allowing for the separation of the substances. In contrast, 3 phase decanter centrifuges use centripetal pump technology to achieve solid-liquid-liquid three-phase separation, as opposed to Shenzhou Machinery 2-phase centrifuges, which are utilized for solid-liquid two-phase separation and discharge the solid slag and separation liquid from an opening at the bottom of the equipment collection box. Under the pressure of the centripetal pump, the heavy liquid phase is discharged through the flow outlet on the impeller. In contrast, gravity sends the solid slag and light liquid phase down from the bottom opening of the equipment collection box.
What industry is the decanter centrifuge used for? Decanter centrifuge working principleļ¼Centrifuges are useful in most industries where solids, liquids, and gases are mixed into a single substance, but separating the components is necessary. For example, decanters (also known as solid bowl centrifuges) continuously separate solids from liquids in slurries and therefore play an essential role in wastewater treatment, chemical, petroleum, and food processing industries. The basic principle of a decanter centrifuge relies on buoyant separation. The denser ingredients will fall to the bottom of the mixture while the less dense ones are suspended above. Due to a large centrifugal force, decanters rotate to separate the substances inside quickly. Before decanters were used, components took hours to settle, but a decanter centrifuge can take only a few seconds.
The full name of the decanter centrifuge is the horizontal screw decanter centrifuge, which is a widely used equipment in the field of industrial solid-liquid separation. According to the characteristics of different materials in different industries, Decanter centrifuge is divided into dewatering, separation, and clarifying decanter centrifuge. With centripetal pump technology, decanter centrifuge can also realize the 3-phase separation of liquid, liquid, and solids or two liquid phase separation. Decanter centrifuge can separate over 50%(v/v) solids from liquids on a continuous basis.Typical industrial decanter applications include Crude oil tank bottoms ,waste oil industrial,wastewater,sludge Decantering,Fish meal,WVO/UVO Desludging,Paint sludge ,Etc.

The structure and working principle of a Decanter centrifuge – The Decanter centrifuge relies on the density difference between solid and liquid phases, and under the action of centrifugal force, accelerates the settling speed of solid particles to achieve solid-liquid separation. There is a conical section designed in front of the drum, which rotates at a set speed according to the different properties of the material. The material rotates at the design speed on the inner wall of the drum, forming a concentric liquid layer along the drum shell, called the liquid ring layer. The solids contained in the material are deposited onto the wall of the drum under the action of centrifugal force, and then the dry material is pushed out of the drum through spiral operation. The operating speed of the drum directly determines the separation factor, while the speed difference of the screw directly affects the solid moisture content transported outside the drum. It has a direct impact on processing capacity, residence time, and solid discharge.
