A new depth filter media was designed and samples of flat sheet as well as cartridge assembly were prepared and tested to evaluate the filtration performance and compare with the commercial product. The arrangement of the depth filter media layers is important to reach the optimal filtration parameters like filter pressure drop, particle collection efficiency and dust holding capacity. Initially, both flat sheet samples of new media and commercial product have been tested using standard test units. Tests with new depth filter media cartridges of various pleat count were conducted in order to find the optimal pleat count which would represent the lowest pressure drop. These tests give an insight on how the pleat count and the assembly configuration affect the performance of the depth filter media cartridge. By comparing the samples with a commercial product we could confirm relatively high filtration performance of the sample cartridge with pleat count 150 made of new depth filter media. The cartridge with the same pleat count exhibits better performance without the outer mesh.

Objectives: Many types of dust collector are used for industrial ventilation, with the most common types being the cylinder bag filter system, rectangular bag filter system and cylinder type cartridge filter system. The cylinder type cartridge bag filter, which has more filtering area than other types of bag filter, can increase the pulse time and extend the useful life of the filter. This can save operational costs and installation area. Materials: This study used cylinder type cartridge bag filter equipment and tested the impact of vibration level and filter pressure with different pulse jet cleaning conditions. The final, cleaning efficiency was calculated through input dust mass and cleaning dust mass Conclusions: Two optimum cleaning condition groups were found. The first condition group was $3kgf/cm^2$ pulse pressure, 15 cm pulse distance, 0.2 s pulse time with an H-10 type nozzle. The second condition group was $3kgf/cm^2$ pulse pressure, 15 cm pulse distance, 0.3 s pulse time with an H-10 type nozzle.

The effects of pleating parameters on the performance of cylindrical cartridge air filters was experimentally studied. The tested filters are 150 mm in outer diameter and 700 mm in length. As the pleat count increases, the pressure drop across a cartridge filter is decreased for a constant pleat depth and flow rate. This is due to the increased filtration area which brings out less pressure loss of the filter. However, in the case of the filters having the pleat depth of 40 mm, the inner diameter of the cartridges is so small that the pressure loss is greatly increased.

Cartridge filters are widely used in liquid-solid separation processes. To select a proper filter system for the requirements of a given application, a knowledge of filter efficiency and dirt capacity is required. The filter manufacturer needs to provide data which are based on test procedures simulating real parameters on a laboratory scale. There does not exist at present a standard for liquid filter testing (with the exception of the Multipass Test to ISO4752 for hydraulic filters). Users have to work with data based on different test procedures. This paper will discuss principles of filter testing, efficiency andd dirt capacity results as a function of test parameters, and data interpretion to provide a guideline for the end user.

현재 존재하는 다양한 filtration 테크놀러지는 feed stream으로부터 제거되는 파티클의 사이즈에 근거하여 그 범주를 정할 수 있다. 부유 고체물의 재래식 macrofiltration 은 feed solution이 수직 방향으로 filter media을 통하여 흐르게끔 하는 것이다. 전체 용액은 메디아를 통하여 지나가는데 단지 한개의 stream만 만든다. 그런 여과 장채의 보기를 들면, cartridge, filter, bag filter, sand filter, multimedia filter들이 있다. Macrofiltration separation은 1 미크론 이상가는 비용해성 파티클에 국한된다.

In order to decrease the high costs of membrane process, we have tried to develop two alternatives to membrane; a cartridge type filter and a metal membrane were tested for the high permeation flux with low cost and low energy. This research mainly focused on three points; 1) operation with high permeation flux by using of a cartridge type filter and a metal membrane, 2) removals of the filterable organic materials (FOC) by pretreatments for the membrane fouling control, and 3) advanced wastewater treatment by SMBR process with intermittent aeration and high MLSS. An Intermittently aerated membrane bioreactor using a submerged micro filter (cartridge type) was applied in laboratory scale for the advanced wastewater treatment. To minimize membrane fouling, intermittent aeration was applied inside of the filter with $3.0kg_f/cm^2$. The experiments was conducted for 6 months with three different HRTs (8, 10, 12 hr) and high MLSS of 6,000 and 10,000mg/L. The filtration process could be operated up to 50 days with permeation flux of 500LMH. Regardless of the operating conditions, more than 95% of COD, BOD and SS were removed. Fast and complete nitrification was accomplished, and denitrification was appeared to be the rate-limiting step. More than 75% T-N could be removed due to the endogenous denitrification. T-P removal efficiency was increased to 80% under the condition of MLSS 10,000mg/L.

Precipitator is the most widespread device used to separate dust particles from the exhaust gas. In the shipyard, welding umbrellas, spark protection covers, and ventilators are not purchased and used for the work place to capture the flames and high temperature metal dust generated during the gardening process. In particular, a thorough analysis of design factors, such as capture rate, collection capacity calculation, filter speed, and materials selection, is required since spatial constraints are followed by structures, etc. In this study, conceived to address problems such as this cyclone and filtration filter system that combines all-in-one gausing collector prototype. Assessed through interpretation through the validity of the design and reliability.

본 연구는 외국제품과 동등 또는 이상의 품질을 가진 고효율성 수처리 필터의 제조와 그 공정을 개발하는데 목적이 있다. 개발된 필터의 여과효율은 93~99%로 기존의 국내산 82~97.5%, 일본산 92.5~98% 보다 우수하거나 유사하였다. 오염 입자의 양에 따른 압력손실(내구성)은 기존의 국내산보다는 현저하게 작았으며 일본산과 비교해도 약 $0.1kg_f/cm^2$의 낮은 압력 손실을 나타내었다. 또한 본 연구에서 개발된 카트리지 필터는 일본산 제품에 비하여 약 50%의 가격으로 생산이 가능하므로 기존의 국내산 제품뿐 아니라 일본산 제품에 대한 수입대체 효과도 기대할 수 있다.

The hydraulic pressure system can deliver strong power and control is easy so that it have been applied to the element technique of an each industrial field. Apply range is the actual circumstances to be more widening according to the automation plant and trend of the manufacture facilities. The hydraulic pressure system have been used since early times and it was universalized considerable in the industrialized country. Utilized to an automation device instrument wide at an each industrial spot and contributed the air space development which contribution make great strides for robotics and airospace departments. Our circuit design technology for the device structure are weak and in fact domestic is depending on the income though importance of the hydraulic pressure system.
