Best disc stack centrifuge manufacturer factory: 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 materials then flow into the inner cavity of the bowl, which rotates in synchronization with the bowl. Because of their different specific gravities, the three types of centrifugal forces are as follows: the strongest for solids, the second strongest for heavy-phase liquids (like water), and the weakest for light-phase liquids (like oil). This allows the centrifugal force to work magic, forming an outer solid layer and two inner liquid layers. The solid material that has been deposited on the inside wall of the bowl is moved to the machine’s solid outlet using the screw, where it is dried further using extrusion and subsequently released. Meanwhile, the liquid material flows to the machine’s liquid phase outlet and overflows at various points, separating the solid, heavy, and light liquid phases. The Shenzhou Machinery 3-phase decanter centrifuge uses centripetal pump technology to determine the optimal placement of the liquid discharge layer based on the relative proportions of the heavy and light liquid phases and to adjust the position of the neutral layer of these phases. Additionally, the centripetal pump serves as the heavy liquid phase flow outlet, making it an ideal choice for pipeline layout.
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.
High Speed Tubular Centrifuge, also called Tubular Bowl Separator or tubular bowl centrifuge, is a kind of fine separation equipment suitable for suspensions with thin concentration, fine particles, and small density difference solid-liquid separation, or liquid-liquid-solid separation. It is indispensable equipment for pharmaceutical, food, chemical, biological product, fermentation broth, beverages, blood products and other industries. High Speed Tubular Centrifuge working principle is that materials with different specific gravity are subject to different centrifugal forces when rotating at high speed, so as to achieve the purpose of separation.

The use of three-phase separation technologies is rising in the separation industry. When it came to separating oils and water, the industry particularly needed high-efficiency three-phase decanter centrifuges. Shenzhou Machinery Company has over 50 years of experience in the separation field, which they used to develop the 3 Phase decanter centrifuge. Its primary use is in solving the problem of simultaneous immiscible liquid and solid phase separation using the specific gravity difference. The need for stable, continuous operation around the clock can be met by the 3 Phase decanter centrifuge thanks to its mature design and high-quality raw material selection.
Rotary drum diameter. The diameter of the Decanter centrifuge is 180-920mm, which means that the theoretical volume separation range is 1:130 when the diameter to length ratio is the same. The diameter of a Decanter centrifuge cannot increase indefinitely, because as the diameter increases, the allowable speed will decrease due to the decrease in material strength, resulting in a corresponding decrease in centrifugal force. From an economic perspective, it is not possible to increase the flow rate of a Decanter centrifuge by increasing its diameter. The ratio of drum diameter to length. In the past, the aspect ratio remained at 1:2, but now it can reach 1:3 or 1:4 (or even higher). The diameter to length ratio has an impact on the residence time of materials in the clarification zone, as it determines the volumetric flow rate of the centrifuge. The diameter to length ratio does not have a significant impact on the solid flow rate, but it has an impact on the moisture content of the mud cake.
