1 Salt sludge is the waste produced in the process of refining raw salt in the chlor-alkali industry. China's caustic soda enterprises used in the poor quality of raw salt produced by the amount of salt sludge is relatively large. Enterprise caustic soda production capacity of 210,000 t / a discharge of salt mud containing water mass fraction of about 95% of 190,000 t / a. A large number of salt mud waste directly discharged into the gutter not...
Caustic soda plant caustic soda production unit original design Scale of 1.5 million t / a small-scale process facilities backward salt sludge treatment process is simple and labour-intensive workers salt sludge after simple treatment will be discharged in the sludge with high salt content not only caused by waste but also caused serious environmental pollution. 2007 the company will be salt sludge from the pipeline outside...
I. Project Background Filter Press With the rapid growth of urban population, urban water pollution is facing serious challenges. In order to quickly solve this problem, in recent years, urban sewage treatment plants in large-scale construction, in the process of sewage treatment, the sludge produced has become a new source of environmental pollution, such as treatment is not timely...
Filter press installation and commissioning process Industrial filter presses are large mechanical equipment that must be installed and commissioned before they can be used. They cannot be used immediately after purchase, but must be installed and tested before use. Therefore, the installation procedure of filter press is also a concern for companies and businesses. So let us first understand the filter press equipment...
Introduction to filter press cloth life Filter press cloths play a key role in optimising filter press operation. The success of your filter press system in delivering absolute results depends on one factor, the condition of the filter cloth. Worn, damaged or too old filter cloths will prevent your system from achieving the filter clarity and slurry required for your programme. By...
1Ultra High Pressure Filter Press Coal sludge is a by-product of the washing and processing of raw coal in coal preparation plant. For power coal beneficiation plant coal slurry generally refers to primary coal slurry, and coking coal beneficiation plant coal slurry generally refers to flotation tail coal slurry. Part of the coal slurry particle size composition of the coarse coal preparation plant can be used to pressurised filter recovery, a few coal preparation plant...
With the continuous progress of urbanisation, a large number of production and living sewage discharge and treatment has become a key topic of concern. Many sewage treatment plants sewage treatment pressure is getting bigger and bigger, especially some urban sewage treatment plants whose sludge content is often high, which directly affects the effect of sewage treatment. Most of the sludge carries...
At present, plate and frame filter press sludge treatment is getting more and more attention, and various sludge dewatering technologies, processes and equipment are gradually introduced into sewage treatment design. Plate and frame sludge dewatering system has been widely used by virtue of its unique advantages such as high sludge solid rate and low energy consumption. Strengthen the new plate and frame sludge dewatering technology...
Most of the paper industry adopts the form of incineration to deal with sludge, the burning calorific value of sludge incineration and its moisture content of the correlation is very large, absolute dry solid sludge has a high burning calorific value, the higher the moisture content of the sludge the lower the burning calorific value. Therefore, the deep dewatering of sludge and the reduction of sludge water content are important links in sludge treatment ....
Wuyang Coal Mine Coal Processing Plant 2.4 million t/a new plant was completed and put into operation in January 2008, the coal processing process adopts heavy media cyclone + TSS separator + flotation. Filter press is an important part of the coal slurry water treatment system, whether the operation is normal constraints on the production of the coal preparation plant, 2.4 million t / a new plant was built than the old plant's production capacity has a great...
1 filter press introduction 1.1 The application of the filter in recent years, people have further recognised the importance of solid-liquid separation, recognising that it is closely related to the effective use of resources, energy and environmental issues, and therefore in theory and technology have made a lot of research work, and achieved promising results. Solid-liquid separation i...
Application analysis of filter press in PTA industry PTA production process includes oxidation and refining 2 parts, refining is to use hydrogen to reduce 4-CBA to PT acid and through the separation to get PTA. terephthalic acid and PT acid solubility in water is very different, in 150C, terephthalic acid in 100g of water solubility is only 0.03g...
Introduction Lithium iron phosphate powder comes partly from the trimmings produced in the process of cutting the pole pieces in the battery factory; the other part comes from the scrapped lithium iron phosphate power batteries and the recovered positive pole pieces. Both trimmings and positive electrode wafers need to be crushed, vibration sieved and separated from aluminium foil and lithium iron powder. Aluminium foil can be sold directly to aluminium refineries...
0Introduction Lithium iron phosphate (LiFePO4) with olivine structure is a commonly used cathode material for lithium ion batteries, which has the advantages of good thermal stability, high safety, long cycle life, wide source of raw materials, and no environmental pollution, and it is recognised as the most promising development potential for lithium ion batteries in recent years...
Introduction of sludge treatment filter press process -High-pressure filter press dewatering and solidification integrated‖ treatment system is a specially developed sludge and water detachment treatment system in this paper according to the characteristics of urban rivers, lakes, especially water conservancy projects with high organic matter content, high water content and serious heavy metal pollution. The core technology is researched and developed...
0 Introduction Xinzhuang Coal Mine of South Shenhuo Coal & Electricity Co., Ltd. is located in the eastern part of Yongxia Mining Area of Yongcheng City, Henan Province, with the current approved production capacity of 1.8 million t/a, and adopts the main shaft, dark inclined shaft, and centralised big lane development method. The mine has a total of 6 water silos and 6 sedimentation ponds in the bottom of the south sub-shaft, the bottom of the north sub-shaft and the 27 mining area, which were originally adopted by man...
