What is filter press sludge? Sludge refers to the solid sediment produced by the water and sewage treatment process. The viscosity, temperature and chemical composition of the sludge produced by different industries are different. Sludge is also an extremely complex heterogeneous body composed of organic debris, bacterial cells, inorganic particles and colloids. If all kinds of industrial sludge and wastewater are discharged directly without treatment, due to their special properties, it is easy to cause environmental pollution to air, soil, water quality, etc. Therefore, in response to environmental protection policies, many industrial enterprises have introduced filter press series products. After the sludge is separated and dehydrated from solid and liquid, the clean water can be recycled again, which is energy-saving and environmentally friendly. The main feature of sludge is high water content, up to 99% or more. Due to the high content of organic matter, it is easy to rot and smell, and the particles are finer, the specific gravity is smaller, and it is in a colloidal liquid state. It is a thick substance between liquid and solid, which can be transported by pump, but it is difficult to separate solid and liquid by sedimentation. Therefore, the filter press developed and produced by our company appeared just right, and played an important role in the solid-liquid separation of sludge. Well, not every filter press is suitable for all sludge and sewage treatment. Users still need to make corresponding choices according to different material properties. At present, our company produces plate and frame fi

A filter press is a type of pressurized filter. Filters can be divided into three types according to the different filtering forces, namely gravity filter, vacuum filter and pressure filter. The pressure filter is based on the pressure applied at the inlet of the suspension or the mechanical pressing force applied to the wet material as the driving force for filtration. It is suitable for use in suspensions that require a large filter pressure difference. It can also be divided into There are two kinds of intermittent operation and continuous operation. Intermittently operated shell and tube filter presses and pressurized filters for filtration of low-concentration suspensions. The filter press is also a pressurized filter with intermittent operation, which can be divided into three types: plate and frame type, box type and vertical type, and has a wide range of uses. The oil filter unit is a plate and frame filter press unit equipped with oil pumps, vacuum evaporators and other accessories. Continuously operating drum pressure filter and disc pressure filter perform pressure filtration in a closed shell, and their structure is very similar to drum vacuum filter and disc vacuum filter. However, due to its complex structure, it is rarely used. Commonly used pressure filtration is to use the volume of the filter chamber to decrease or apply mechanical pressure to filter. The moisture content of the filter residue is low, and it is suitable for high-concentration solid particle suspensions. In the belt press filter, the wet filter residue after preliminary dehydration by gravity or vacuum moves between two filter belts, and then is deliquored by roller extrusion. The screw press filter has a cylinder
Which parts of the membrane filter press should not be too hot?
2022 / 11 / 22
Introduction The appearance of the membrane filter press has brought a different experience to the vast number of industrial production users in the process of pressing and filtering. Nowadays, membrane filter presses have been widely used in various fields that require solid-liquid separation. The diaphragm filter press may overheat during long-term work, but the overheating of some parts will have a certain impact, so pay attention to observe the temperature, and it should not be too high. 1. Membrane filter press hydraulic station The hydraulic station in the diaphragm filter press is an important part of using storage oil and pumping oil. When the temperature of the hydraulic station is too high, the stability of the oil will change, so the hydraulic oil will lose its anti-pressure performance. At this time The device will lose pressure. 2. Membrane filter press filter plate Some membrane filter press filter plates are made of plastic. When the temperature of this filter plate increases, the replacement cycle of the filter plate will be shortened and the rupture of the filter plate will be accelerated.
Deep dewatering of sludge: How to choose the sludge filter press?
2022 / 11 / 14
Introduction In sludge treatment, the selection of sludge treatment equipment directly affects the sludge treatment effect, so how to choose the sludge filter press? Shenzhen Hongfa Environmental Protection Equipment Co., LTD., a supplier of sludge treatment equipment, summarized the following three evaluation factors. Degree of sludge treatment Nowadays, the relevant environmental laws and regulations stipulate that the sludge can be landfill or resource utilization only when the moisture content is below 60%. Therefore, when selecting the sludge filter press, we must ensure that the moisture content of the sludge treated by the sludge treatment equipment reaches the standard. This is also the primary consideration for the selection of sludge filter press. At present, there are both ordinary sludge filter press and ultra-high pressure sludge deep dewatering filter press on the market, such as ShenHongfa sludge presser, etc. For the long-term consideration of sludge disposal engineering, it is recommended to choose sludge deep dewatering equipment. Sludge treatment efficiency There are many sewage treatment plants or industrial enterprises, because the sludge treatment equipment processing capacity can not reach the amount of sludge production, often resulting in sludge accumulation situation. The sludge treatment efficiency of the same type of sludge filter press produced by different sludge treatment equipment suppliers is very different. For example, the slud

Application of Diaphragm Filter Press in Dewatering of Scheelite Concentrate
2022 / 08 / 11
The daily processing capacity of ore dressing is 15,000 tons/day, and the development of the processing plant is limited due to the insufficient dewatering capacity of tungsten concentrate. A box-type filter press was introduced, which has high moisture content in the filter cake and low productivity and efficiency, which restricts the production of the dressing plant. Therefore, the introduction of a program-controlled automatic plate-pulling diaphragm filter press not only reduces the labor intensity of workers, but also reduces the moisture of the filter cake, so that the insufficient dehydration capacity of scheelite concentrate can be solved, and the production capacity of the dressing plant can be optimized. 1 Structure, working principle and performance characteristics Structure and working principle. The actual working principle of the program-controlled automatic plate-pulling diaphragm filter press mainly refers to the accurate pressing of the filter slurry by means of pressure pump equipment. Usually, it needs to be pressed into the closed filter chamber composed of two adjacent filter plates. Thus, the corresponding pressure difference is formed, and the solid-liquid separation operation is finally completed. At this stage, the program-controlled automatic plate-pulling diaphragm filter press is designed with the help of mechanical, electrical and hydraulic integration in terms of manufacturing, which can achieve rationalization of the structure and operate The simplification of the filter, and it is relatively convenient, safe and reliable in terms of maintenance work. The automation of related processes such as loosening at the management control level.

Why do you need the work of a filter press in sewage treatment?
2022 / 06 / 06
Environmental protection and green is an important criterion that every factory needs to practice, in the daily operation process of the factory and mine, it is inevitable that many sewage wastewater will be generated, if it is not effectively treated, but directly discharged into the environment, it will aggravate the pollution of the environment and water quality, and also adversely affect the nearby residents, it is difficult to drink water and live normally. The emergence of filter presses can solve this problem very well, separating the waste in the sewage from the water phase, and the water can be directly recycled, so as to achieve the purpose of green and environmental protection. When using the filter press, we must understand the working principle of the equipment, and do reasonable inspection and maintenance of some abnormal situations that are likely to occur in the daily operation of the equipment to improve the utilization efficiency and service life, and these put forward higher requirements for the use of the filter press. The effect and application range of the filter press for sewage treatment are relatively wide, and can separate the sewage impurities with high difficulty of separation, such as some suspensions with low concentration or solid liquid with high viscosity. For example, the chamber filter press, its working principle is to use the gap on both sides of the filter plate to separate the solid liquid, because the filtration pressure of the machine is high, so it is suitable for filtering materials with more impurities, and is widely used in liquid filtration containing trace solid impurities. In the use of the filter press, these should be kept in mind! 1. When the equipment starts to carry out sludge filtration and dewatering, it is first necessary to start the chemical pump, adjust the flow rate of the pump, let the dissolved and absorbed flocculant be placed in the mixer for fiv

High pressure menbrane filter press in copper tailings dewatering applications
2022 / 04 / 21
Copper tailings, also known as copper tailings sand. In China, copper tailings are the second largest source of tailings after iron tailings. In the process of copper ore flotation, due to the wide application of mineral processing agents, the waste ore slurry contains many toxic substances and heavy metals, which not only seriously threatens our ecological environment, but also seriously challenges the living environment of surrounding residents. At present, tailings dams are still the most common treatment method, but there are great safety risks. In order to solve the above drawbacks and achieve dry drainage, filter presses have been widely used in this field. The working effect of the high pressure menbrane filter press is outstanding, and it has excellent performance, full automation, improved maintenance effect, reduced operating costs, and the moisture of the filter cake is lower than that of the traditional plate and frame filter press and belt filter press. According to our experience, because copper tailings have the characteristics of relatively high solid content, relatively fine ore particles and large viscosity. If a conventional plate and frame filter press is used for press filtration and dewatering, the cycle time is longer and the efficiency is lower. In order to solve this problem, the following process can be used: cyclone - dewatering screen - thickener - high pressure menbrane filter press. The process is not only suitable for tailings with fine particles, but also has the characteristics of small one-time input, small footprint, high efficiency, good dehydration effect and low operating costs. The details are shown in the following figure: First, the slurry is particle-graded through a cyclone. Coarse

Plate and frame filter press 1. The plate and frame filter press (plate and frame filter press) consists of alternately arranged filter plates and filter frames to form a group of filter chambers. The surface of the filter plate has grooves, and its protruding parts are used to support the filter cloth. There are through holes on the corners of the filter frame and the filter plate, which form a complete channel after assembly, which can pass in the suspension, wash water and lead out the filtrate. There are handles on both sides of the plate and the frame, which are supported on the beam, and the plate and the frame are pressed by the pressing device. The filter cloth between the plate and the frame acts as a sealing gasket. The suspension is hydraulically pumped into the filter chamber by the feed pump to form a filter residue on the filter cloth until the filter chamber is filled. The filtrate passes through the filter cloth and flows along the groove of the filter plate to the corner channel of the plate and frame, and is discharged centrally. After filtration, the filter residue can be washed with clean water. After washing, compressed air is sometimes introduced to remove the remaining washing liquid. Then open the filter press to remove the filter residue, clean the filter cloth, re-press the plate and frame, and start the next working cycle.

The difference between automatic diaphragm filter press and traditional box filter press
2022 / 02 / 28
The automatic diaphragm filter press is a great improvement compared with the traditional box filter press. The similarity between the two is that the initial way of working is basically similar. The difference is that the traditional box filter press only relies on the feed pump to transport the material through the pressure between the fluids for extrusion and dewatering; and the diaphragm filter press adds a diaphragm filter plate in the middle of the filter plate, and after the air pressure or liquid pressure is delivered to the diaphragm filter plate, the whole diaphragm will bulge to both sides, and the pressure of the tympanic membrane will once again perform secondary pressing and dehydration of the filter cake. With the increase of pressure, the water involved in the material will be squeezed out after the first squeeze and dehydration, so that the filter cake achieves a lower moisture content. It is generally possible to reduce the moisture content of the filter cake to about 30%-40% (according to the pre-treatment process and material related), which also improves the solids content of the material and greatly reduces the cost of transportation.
High pressure membrane filter press
2022 / 02 / 22
The present sludge processing operations at the District consist of heated anaerobic digestion, dewatering by centrifugation, and air drying. A critical unit operation in the overall sludge processing train is the mechanical dewatering step. Typically, sludge dewatering by the District's existing centrifuges produces a cake having a solids content of 15%. Four different types of mechanical sludge dewatering machines were evaluated in a pilot test program to determine if these machines could produce cakes having greater solids contents than that produced from the existing centrifuges. The machines tested were two modified versions of the conventional horizontal solid bowl centrifuge design, a screw press, and a diaphragm filter press. The two modified centrifuges produced cakes having average solids contents of 20% and 29.4%, respectively; the screw press produced a cake having an average solids content of 17.5%, and the diaphragm filter press produced a cake having an average solids content of 29.4%. Based on the pilot test program, a test evaluation program was conducted using full-scale centrifuge machines of the modified designs. The preliminary results of this test program confirmed that centrifuges can produce a cake with a solids content approximately equal to or greater than 30%.
