Perhaps you’ve been told that your application could benefit from a filter press, but you don’t fully understand how the technology or filtration equipment work or how it could help your operation.
Safi Sazan Safa is the biggest, first and leading manufacturer of filter presses and advanced liquid filtration technology. Here, we’ll explore the question – how does a filter press work? We will also examine the applications where they are most frequently utilized, and some of Micronics’ standard and custom filter press solutions.
A filter press is a piece of equipment used in liquid/solid separation. Specifically, the filter press separates the liquids and solids using pressure filtration, wherein a slurry is pumped into the filter press and is dewatered under pressure. Basically, each filter press is designed based on the volume and type of slurry that needs to be dewatered. Micronics, Inc. is a trusted expert in liquid/solid separation and offers a wide range of filter press types and capacities to suit specific application needs for trouble-free, economical dewatering. These include configurations such as sidebar automatic, and hand filter presses.
The four main components of a filter press include the frame, filter plates, manifold (piping and valves), and filter cloth, a key ingredient for optimizing filter press operations.
The working principle of filter presses is that slurry is pumped into the machine such that solids are distributed evenly during the fill cycle. Solids build up on the filter cloth, forming the filter cake; the filtrate exits the filter plates through the corner ports into the manifold, yielding clean filtered water.
Filter presses are a pressure filtration method and as such, as the filter press feed pump builds pressure, solids build within the chambers until they are completely chock-full of solids, forming the cake. Once the chambers are full, the cycle is complete and the filter cakes are ready to be released. In many higher capacity filter presses, fast action automatic plate shifters are employed, speeding cycle time. Some filter presses are specifically designed for fully automatic, 24-hour operation in a harsh environment such as mines or chemical manufacturing plants.
Filter presses can be built in a wide range of sizes, from small, lab-scale 150 mm presses, to those with much larger capacities, such as those with 1500 and 2000 mm filter plates. Filter presses are used for liquid/solid separation in an extensive range of industries and applications including:
The industry, application and operational considerations will guide specifics such as the overall design, filtration capacity, number of chambers, filter plate size, materials of construction, as well as additional features/systems such as automatic plate shifters, cloth washing system, drip trays, cake shields and safety light curtains. Design of a filter press depends on a host of factors such as filtration cycle time, cake dryness required, cloth life, whether manual or automated plate shifting is desired, and many other factors.
تاریخچه در خصوص تاریخچه فیلترپرس می توان گفت اولین شکل فیلتر پرس در انگلستان بتاریخ 1853 میلادی اختراع شد، که برای بدست آوردن روغن دانه بوسیله استفاده سلولها فشاری بکار گرفته شد. معذالک، این سلولها معایب زیادی داشت، مانند نیاز بالا به نیروی کار و فرایند غیر پیوسته. پیشرفتهای عمده در تکنولوژی فیلتر پرس در […]
به طورکلی تکنولوژیهای بافندگی و تولید منسوجات به دو دستهی کلی درگیری الیاف باهمدیگر و درگیری نخها باهمدیگر تقسیم میشوند. محصول نهایی در درگیری الیاف باهم پارچهها و منسوجات بیبافت هستند. سادهترین و دردسترسترین منسوج بیبافتی که میشناسیم دستمال کاغذی است. درگیری نخها شامل سه روش برای بافت منسوجات است. این روشها عبارتند از: بافندگی تاری […]
Filter presses are widely used in degreasing and refining edible oils, such as such as in removing stearin from palm oil. With the improvement of people’s living standards, the quality of edible oil has further increased. Defatted edible oil is more beneficial to people’s health, because saturated fatty acids make people fat, and cause vascular diseases. […]
شرکت صافی سازان صفا در سال ۱۳۸۲ در شهرک صنعتی نو آوران واقع در شهر زنجان، فعالیت خود را در زمینه تولید صفحات فيلتر پرس شروع کرده و به دو روش اکسترود در قالب صدفی و روش اکسترود در قالب فورج، صفحات فیلتر پرس را تولید نموده است. این شرکت توان تولید صفحات از سایز ۲۰۰ میلی متر الی ۲۰۰۰ میلی متر را دارد. اندازه های مذکور در مدلهای مدار باز و بسته ، ممبران و قاب و صفحه تولید و عرضه می شود.
