Filter Material-Natural materials successfully filter greywater
Akshara and Suditi tested different natural materials in greywater filtration.PHOTO COURTESY OF AKSHARA LEGALA.Akshara Legala and Suditi Bhatt, two high school students from Sacramento, California, developed and tested greywater filtration systems with natural filters. Greywater is a way to recycle used water, and a method environmentalists tout to save freshwater resources for drinking while greywater could be used for appliances and agriculture.Nurturing the next generation of scientists — like these young women — is one of our main goals at the Society for Science & the Public. To help us reach this goal, the Society recognized 20 students competing in science fairs throughout the country to recognize their STEM efforts. These Community Innovation Awards, part of the Society’s STEM Action Grants, recognize amazing young scientists.Read on below to learn how their device works and how they first became interested in science.អានបន្ថែម -
Filter Material-How to Make a Survival Water Filter
Is it safe to drink this water? I ask myself that question often and most of the time the answer is no. There often is the risk that bacteria, chemicals, and pathogens, specifically Giardia, are in the water. Rainwater or dew that is resting on non-poisonous plants such as moss is safe to drink as is. There are a few ways to process water to make it safe to drink: boiling it, using chemical purifiers, and filtration. This article will provide tips on how to make and use a survival water filter.អានបន្ថែម -
Filter Material-Filter material containing bamboo fibers and active carbon
The utility model relates to the field of filter materials, in particular to a filter material containing bamboo fibers and active carbon. The filter material comprises a first nonwoven fabric layer, a second nonwoven fabric layer and a bamboo fiber filter layer and an active carbon filter layer, wherein the bamboo fiber filter layer and the active carbon filter layer are compounded between the first nonwoven fabric layer and the second nonwoven fabric layer. According to the filter material containing the bamboo fibers and the active carbon, after the structure is used, by using good permeability, instantaneous water absorption, natural antibiosis, bacteriostasis, mite removal, deodorization, ultraviolet resistance and other excellent properties of the bamboo fibers, and superhigh adsorption capacity of the active carbon, the functions of filtering, cleaning, bacteria removing and the like of the filter material are greatly improved and enriched, moreover, because the bamboo fiber has strong abrasion resistance and the reproducibility of the active carbon, the service life of the filter material is prolonged.អានបន្ថែម -
Filter Material-Different Types of Filter Media/Fabric Rolls And Their Benefits
Filtration systems are essential components of everyday life whether you are at home, driving to work or in an industrial setting. Homes and offices need air filtration systems to keep the air free from dust and contaminants. Vehicles and heavy machinery need oil and fuel filtration systems to prevent the contamination of their engines. Industrial facilities use filtration systems to purify their waste gases and wastewater before disposal.The efficiency of all filtration devices relies on the quality of their filtration media. Yet, the substance and contaminants you are dealing with determine the type of filtration devices and filter media roll you use. This article draws attention to different types of filtration fabric media and their benefits. Read on if you would like to find out more about these types of filter media.អានបន្ថែម -
Filter Material-how to choose the appropriate filter material
A hydrophobic membrane, such as polytetrafluoroethylene (PTFE) will resist any aqueous sample, creating back pressure. Although it is sometimes possible to overcome this back pressure with additional force, there is a risk of membrane rupture and incomplete filtration.Should there be no alternative, pre-wetting the membrane with an alcohol can reduce this back-pressure effect.PTFE and other hydrophobic materials are well suited to organic samples and solvents, which result in no resistance or back pressure. However, some organic solvents can absorb into the membrane material, especially when in contact for long periods.This absorption makes the material swell, reducing pore size and affecting the performance of the filter. Some solvents might also chemically attack the material, releasing extractables into the filtrate. In rare cases, a solvent might partly or fully dissolve the membrane, resulting in breakthrough and potential contamination of the sample.Aqueous samples are unlikely to damage most membrane materials, particularly hydrophilic. However, pH is a significant factor in determining membrane compatibility.Strongly acidic or alkaline solvents might not immediately damage a membrane but can have an effect over time. As such, only highly inert membranes such as PTFE are suitable for high and low pH samples.អានបន្ថែម -
Filter Material-Filtration
Filtration is a physical separation process that separates solid matter and fluid from a mixture using a filter medium that has a complex structure through which only the fluid can pass. Solid particles that cannot pass through the filter medium are described as oversize and the fluid that passes through is called the filtrate.[1] Oversize particles may form a filter cake on top of the filter and may also block the filter lattice, preventing the fluid phase from crossing the filter, known as blinding. The size of the largest particles that can successfully pass through a filter is called the effective pore size of that filter. The separation of solid and fluid is imperfect; solids will be contaminated with some fluid and filtrate will contain fine particles (depending on the pore size, filter thickness and biological activity). Filtration occurs both in nature and in engineered systems; there are biological, geological, and industrial forms.[2]អានបន្ថែម -
Filter Material-Different Types of Materials Used in HVAC Filters
Along with fiberglass, some HVAC filters are made of pleated cotton.They consist of the same cotton used in countless other everyday products. The cotton is pleated and formed into an HVAC filter for the purpose of air filtration.You might be surprised to learn that pleated cotton HVAC filters are even more effective at removing particulate matter from the air than fiberglass HVAC filters. On the Minimum Efficiency Reporting Value (MERV) scale, they have a rating of six to 13, compared to just three to four for that of fiberglass HVAC filters.Another advantage of pleated cotton HVAC filters is their ability to produce static electricity.Why is this important? When a pleated cotton HVAC filter produces static electricity, particulate matter will cling to it.With that said, pleated cotton HVAC filters are more expensive than fiberglass HVAC filters, and they usually have a shorter lifespan.អានបន្ថែម -
Filter Material-What is a filter cloth?
At K2TEC, the term filter cloth for industrial filtration covers all products that are manufactured using a so-called complex weave as opposed to mesh filter fabrics, which are a square weave.Filter cloths have different types of yarns such as monofilament, multifilament, staple fibre, in different natural or synthetic materials such as polyester, polyamide (nylon), polypropylene, PTFE (teflon)…These filter cloths offer filtration ratings from 1 micron to 1000 microns. This type of fabric is generally used in solid-liquid separation but also in air filtration, either directly or as a support for finer specific filter media.Generally on this type of filter fabrics, the filtration rating is of great importance but also the permeability to increase the efficiency of the filter, the mechanical resistance and the dimensional stability. Finally a capacity for cleaning and discharging filter cake.អានបន្ថែម -
Filter Material-The Definitive Air Filter Guide
With lingering air quality problems both inside and out, many people are turning to air purifiers to create healthier, cleaner air in the home. These air purifiers use numerous technologies and have many different components.One of the most important components, however, is the air filter.
