Often, we can not associate the presence of something technically "dirty" such as coal and something perfectly pure as water. However, one of the most important filter elements is exactly the coal. Obviously not everyone: Г©lelmiszer online is a coal specially created to be used as a filter, even on devices that filter the water used in hemodialysis. Perhaps you've heard the name: activated carbon filter. Activated carbon: what's so special
It is very common to use pieces of coal inside refrigerators and freezers to prevent strong odors - and this is a good example of how it has filtering capabilities (in this case, gas). They remove odors because the particles that cause the "stick" in the coal pores. Nowadays, already impregnated with activated carbon artifacts that perform deodorization refrigerators very efficiently. The filters and purification systems that are coupled to the kitchen faucet are also activated charcoal, as well as aquarium filter systems.
The material that ultimately will form the activated carbon filter Г©lelmiszer online is derived from wood, as well as the common carbon, but can also be produced from bovine bone or coconut shell. What will make the final coal suitable for use in filters Г©lelmiszer online is their preparation. The feedstock must be heated to controlled temperatures lying between 800 C and 1000 C for a certain time. The goal of such control is to maintain adequate porosity so that it performs filtering with the required quality level, especially when dealing with medical use. Patients thank. "Go to filter the blood with charcoal ??"
Not directly, but in a way ... it will be present, yes. The process greatly simplified way, is as follows: the patient's blood is drained into the dialysis machine and passes into a filter through which also passes the purified water - only that this water does not mix with blood. It is this filter that exists in a huge amount of fiber semipermeable calls (ie, they are not waterproof sheet such as a plastic, but they are not made a permeable strip of fabric). These are fibers that keeps blood and separate water through chemical processes that prevent them from moving through them. Through movement of blood and water flow (blood flow in one direction and water flows in the opposite direction), impurities from the blood passing through these fibers will follow thereafter and with the purified water coming out of the apparatus by its own valve. Г©lelmiszer online The clean blood leaves by another valve and is returned to the patient.
The reason the water has to be purified is exactly make it to hold blood impurities without "dirty it" even more. It should be filtered, demineralised and chlorine Г©lelmiszer online removed - and it is this part that enters the activated carbon filter. His micropores attract and retain the chlorine particles from the water, leaving it totally free of this element. Important: there is no problem in drinking water treated with chlorine, as is common in our cities; however, the presence of this element directly into the blood generates adverse Г©lelmiszer online reactions and they can be potentially dangerous in patients requiring hemodialysis, which are already very fragile health.
