A PM filter is a liquid microfilter that consists of a seamless pipe made of sintered stainless steel powder. We sinter the fine stainless steel powder using an independently developed method to enable particles of as small as 0.2 µm to be filtered out. This filter has high porosity and stream, and also accurate pore size, and can be used continuously for a long period of time. Features Microfiltering due to accurate pore size   These filters cover an area between 0.2 and 20 µm.For each pore size, we use stainless powder of a certain granularity, then subject it to a continuously integrated process consisting of pressure application, molding and sintering. Large-volume processing by a compact filter due to high stream performance These filters have high porosity (approx. 50%) and the filtering material is thin (approx. 2.0 ~ 3.2 mm), resulting in an extremely small value of P. Also, the grain trapping performance is improved. Seamless, and binder-less The filter is seamless, hence the entire surface of the filtering material can be used. Also, no binder whatever is used to bind the stainless steel power. Consequently, the liquid being filtered is not degraded. Durability Adjacent stainless steel particles form a perfect metallic bond between each other, so there is no possibility of the filter material separating. After high-temperature sintering is completed, the filter is subjected to passivation, enabling it to adequately withstand alkalis, acids, high-temperature liquids and steam High degree of regeneration due to back flushing The filter has an accurate pore size distribution, so its performance can be restored by back flushing it for only a short time. These filters can thus be used for a long period without maintenance. Direct filtering Because the PM filter uses a porous, microfiltering material, there is generally no need to use an filter-aid such as diatomaceous earth. Consequently, the amount of waste generated can be reduced and the filter unit is of simple construction Scope of application Applications Chemical and petrochemical industries   ·Feed water and make-up water ·Polymers ·Adhesives, grease and other viscous liquids ·High temperature liquids ·Frozen liquids, ethylene glycol ·Maintaining and restoring the performance of catalysts, reactors· Recovering particles Foodstuff and brewing industries ·Steam ·Beer, wine, vinegar, Japanese sake and other brewed liquids ·Refining syrups, liqueurs and so on ·Feed water Electronics ·Pure water, ultrapure water ·Iron oxide slurry ·High-speed printer ink Medicine ·Steam used in sterilizing processes ·Test reagents ·Pre-filtering sterilized water, RO and UF systems Thermal and nuclear power generation ·Cleaning boiler circulation water ·Re-using boiler blow water and drain water
