Trevor Sparks, George Chase, in Filters and Filtration Handbook (Sixth Edition), 2016. 2.8.2 Stacked disc filters. Stacked disc filters are similar to the edge filter in appearance, in that they have an array of disc-shaped components held on a central core. The stacked disc filters differ however in that the discs are actually hollow, with filter media over the faces of the disc.
The square design will allow our vacuum to clean the corners of rooms better. ... The typical shape of a robotic vacuum cleaner is a disk. The reasons they are disk-shaped is because of mobility. They can maneuver through tight spaces and still clean effectively. When they bump into a wall or piece of furniture, since it is a circle, it can
PVP's Double Disc Pump™ combines the performance features of a positive displacement pump and the principle of 'induced flow' to provide superior versatility in fluid handling. Based on a 'free-disc' technology, the pump utilizes a unique principle of operation. The pump is based on a non-close tolerance design and does not have the ...
Iso-Disc is a compact, cost efficient alternative to traditional sand filters and other disc filter technologies. It offers a robust yet simple design that can handle peak hydraulic loadings up to 15 m³/h/m2 which equates to single small footprint units capable of 5 – 800 m3/hr. The performance of the Iso-Disc filter is second to none. The ...
1 Preface Oerlikon Leybold Vacuum, a member of the globally active industrial Oerlikon Group of companies has developed into the world market leader in the area of vacuum technology.
Sep 11, 2003· Each filter has a housing design pressure of 225 psig and design temperature of 250°C, with operating conditions around 150 psig and 200C. The filters carry out filtration and cake washing at elevated pressure, enabling removal of impurities that would remain in the filtrate if washing occurred at atmospheric pressure.
flotation concentrates, copper concentrate and other beneficiation processes. The filter consists of several rotary discs, each made up from sectors which are clamped together will form the disc. when compared to other vacuum filters, the floor space required for the disc filter is minimal and the cost per m2 of filtration area is the lowest.
mechanism prior to design work is strongly recommended. In drying of wet solids, the following main factors, which essentially are used in process design calculation of dryers should be defined in accordance with mass and heat transfer principles, process conditions and drying behavior: - Drying characteristics. - Constant-rate period.
Mar 23, 2014· Filtration 1. Shruti Gupta NCAAH 2. Filtration is commonly the mechanical or physical operation which is used for the separation of products like solids from fluids by interposing a medium through which only the fluid can pass. The fluid that passes through is called a filtrate. Filtration is the best established and most versatile method for removing insoluble from dilute streams like ...
