    • Application of plate and frame filter press in filtrate preparation

      Introduction Most of the enterprises use plate and frame filter press to filter the suspension of fine particles with high viscosity and solid content, part of the production process of the filtrate cleanliness requirements are very high, the enterprise in order to meet the requirements of the filtrate cleanliness and the choice of very fine mesh filter cloth, but this brings the phenomenon of long filtration time, high filtration pressure,...

    • Technology and economics of direct pressure filtration versus high pressure diaphragm plate and frame filtration for municipal sludge

      Introduction At present, China's provincial and municipal environmental protection departments of sewage treatment plant sludge water content requirements are basically in accordance with ≤ 60% of the standard implementation, water content failed to meet this standard will face the sludge water content to reduce the upgrading demand. In order to make the sludge water content ≤ 60%, the domestic sludge dewatering equipment often used...

    • Filter Press Dewatering System for Mine Drainage

      Preface Mine production wastewater is first discharged to the -525m level sedimentation tank, sedimentation tank overflow wastewater discharged to the water silo, discharged to the water silo of the overflow wastewater with less sediment content, so the design of this programme focuses on clearing the mud in the sedimentation tank.1 Now the general miscellaneous question waist of a mine -525m level of the existing four sedimentation tanks, under normal circumstances, two sedimentation tanks...

    • Application of filter press on molybdenum concentrate dewatering process

      Introduction With the trend of the product size continues to become finer, more and more mineral processing enterprises in the use of low energy consumption and high output process, a major part of the process is based on the requirements of the end user for the material dewatering, dewatering process can be directly judged by the degree of advanced energy consumption, product waste and loss. For this reason, high hydraulic pressure...

    • Application of plate and frame filter press in acid wastewater treatment process

      Preface Current status of acid-containing wastewater treatment Hydrochloric acid is a commonly used chemical product, which is widely used in the production of steel, electroplating and pickling of steel structural parts. It is also used in  chemical and rare earth production processes. A pickling unit with an annual production capacity of 450,000 tonnes of cold emulsion steel plates requires about 20,000 tonnes of hydrochloric acid per year, generating...

    • Filter press drive mechanism modification research and development

      Introduction With the modern technology is increasingly updated and the rapid development of industry, can be mined mineral resources are increasingly depleted, has been faced with "poor, fine, miscellaneous" situation, therefore, people have to grind the ore finer, and the "fine, mud, sticky" material for solid-liquid separation, in order to Improve the utilisation of minerals. Nowadays, in addition to the saving...

    • Research on dewatering process of filter press in coal processing plant

      Introduction of Coal Slurry Dewatering Coal slurry dewatering for coal preparation plant, penetration in all aspects, in which the filter press in the process, is the most important coal slurry dewatering equipment, it will be a complete separation of solid-liquid, after separation of the filtrate can be recycled again, fast-opening diaphragm filter press through the diaphragm press to further dewatering, and effectively reduce the filter cake water ...

    • 厢式压滤机在盐硝行业卤水净化中应用

      前言 在硝盐或盐硝联产中，从矿区采回的原料卤水中都含杂质钙、镁离子，它们会在加热时形成结垢影响传热。为使生产长周期运行，避免结垢产生，需要对采回的卤水进行净化去除、钙镁离子-从矿区采回的卤水存储在卤...
