filter press

  The operating status of the   fiber rotary disc filter  includes: filtration, backwashing, and mud discharge status. (1）Filtration: outside in and inside out, the sewage gravity flows into the filter body, so that the filter disc is completely immersed in the sewage. At the same time, in order to distribute water evenly everywhere and produce low disturbance in the water inflow, a water distribution weir must be installed in the filter. The sewage is filtered through the filter cloth, and the filtrate is collected through the hollow tube and then flows into the outlet tank and weir to discharge the filter. Filtration is continuous during the entire operation, even during the cleaning process, filtration is still taking place. (2) Cleaning: During filtration, part of the sludge is adsorbed in the fiber wool filter cloth and gradually becomes a sludge layer. As sludge accumulates on the filter cloth, the filtration resistance of the filter cloth increases, and the water l...

  ( 1) The outlet water quality is good and the impact load resistance is high The  fiber rotary disc filter   has a good interception effect. When the inlet water SS is not greater than 20mg/l, the outlet water SS can be less than 5mg/l. The inlet weir is uniquely designed to dissipate energy and prevent disturbance. Filtration and backwashing are performed at the same time. Only 1% of the area of a single disk in the pool is undergoing backwashing at an instant. Filtration is continuous and has strong impact load resistance. (2) Small footprint What is different from the traditional  depth filtration unit  is that the water flow in the traditional filtration equipment generally flows from top to bottom, or from bottom to top, which is a planar direction filtration. The fiber turntable microfiltration unit raises the filter surface vertically, and the water flow flows from left to right. , so many filter surfaces can be arranged side by side, which can reduce t...

  The   LS screw conveyor  adopts international standard products, equivalent to ISO1050-75 standard, and is designed and manufactured in compliance with ZBJ1005.1-2-88 professional standards. It has advanced technical indicators and novel structure. It is the replacement product of my country's GX screw conveyor in the 1990s. Application scope of LS screw conveyor: Screw conveyors are widely used in various industrial sectors, such as building materials, electric power, chemical industry, metallurgy, coal, machinery, light industry, grain and food industries. LS screw conveyor has requirements for conveying materials, including powdery, granular and small lump materials. For example: cement, coal powder, grain, fertilizer, ash, sand, etc. The temperature of the material should not exceed 200°C. The screw machine is not suitable for transporting materials that are perishable, sticky, and easy to agglomerate. Because these materials are conveyed on a screw and rotate with ...

  A typical urban   sewage treatment  process mainly includes mechanical treatment, biochemical treatment, sludge treatment and other sections. The system composed of mechanical treatment and biochemical treatment is a secondary treatment system, and its BOD5 and SS removal rate can reach 90% to 98%. The treatment effect between primary and secondary treatment is generally called enhanced primary treatment, primary and a half treatment or incomplete secondary treatment. There are two main categories: high-load biological treatment and chemical treatment. The BOD5 removal rate can be Reaching 45% to 75%. Secondary treatment systems with biological phosphorus and denitrification functions are often called deep secondary treatment. In order to remove specific substances, the treatment system set up after the secondary treatment is a tertiary treatment, such as chemical phosphorus removal, flocculation filtration, activated carbon adsorption, etc.   The oxidation ditch p...

  Entering winter, rain and snow are ushering in all over the world. Dear friends of   plate and frame filter press , please pay attention to prevent rain and moisture in time. It is not easy to make money, and damaged parts will cause delays in work and work. Be sure to strengthen protection work. In case of equipment failure and For related questions, please communicate with our after-sales personnel or business manager in time to solve the problem. Please do not disassemble it by yourself to cause unnecessary damage. Thank you for your support and love. The purpose of the  filter press   is to squeeze out the moisture contained in the slurry. However, not all weather is suitable for the filter press to work, especially most of the sites are outdoors. If it is at extremely low temperatures, the filter press will not work. If you want to work better, you need to follow some precautions Water is easy to freeze at low temperatures: When the plate and frame filter pres...

  Water is the most important resource for human survival. Whether it is daily life, industrial development, urban construction, etc., will produce a lot of sewage. If left untreated, water will run out one day. In order to survive the continuation of the recycling and utilization of water resources, in addition to sewage equipment is a must for us. There are three common methods for sewage treatment, which are sieve interception method, gravity separation method and centrifugal separation method. Among them, the most used method is screening and intercepting sewage treatment. For example, the   grid clean machine  is a representative processing equipment.   In grid clean machine, grating is an important collection and drainage equipment.  Rainwater screen  and drum grille are commonly used. Rainwater screen is a simple and effective technology that can collect and drain a large amount of rainwater to reduce the possibility of flood. It can effectively prev...
