Filter Materia Are Eco-Friendly and Cost-Effective
Filter Materia are materials that rely on physical barriers to separate particles based on size, density or chemical properties. They are also washable, making them an eco-friendly and cost-effective resource for a wide range of applications.
Cotton fabric is a popular choice because it offers exceptional holding capacity and efficiency while managing contaminant levels. It is also less susceptible to structural manipulation from elevated fluid temperatures.
Cellulose/Paper
Filter paper is a versatile and widely used laboratory tool for separating solids from liquids. It is available in both qualitative and quantitative varieties and can be customized to meet specific requirements such as retention, flow rate, and filter weight. Cellulose filter papers are ideal for a wide range of applications including environmental and soil sampling, chemical analysis, photometric staining, and gas detection.
The main component of filter paper is cellulose, a natural organic polymer found in wood pulp and cotton fibers. During the manufacturing process, lignin is separated from the cellulose and other carbohydrate compounds such as hemicelluloses are removed as well. The resulting paper has a unique structure, with a random matrix of cellulose fibers which capture particulates from fluids.
While cellulose filter papers are a versatile and economical choice, they do require regular cleaning to prevent clogging which will significantly reduce filtration efficiency. It is important to select a filter paper that is compatible with your particular analytical procedure and ensure that it does not introduce significant impurities into the sample. Non-carbohydrate organic impurities can be problematic for delicate techniques such as flame photometry or atomic absorption and can have a substantial impact on analytical results.
Hawach qualitative and quantitative cellulose filters are produced from high quality cotton linters that are treated to maximize alpha cellulose content and purity. These filter papers have the lowest metal background for chemical analyses and are available with a variety of particle size/flow rates to suit your specific laboratory needs.
Spunbond/Synthetic
Spunbond non-woven fabric is an ideal material for filter media because it offers the advantages of a flexible structure and excellent dust brush-off performance. Filter Materia It can be made from a range of raw materials, including a variety of polymers. Its apparent density – a measure of its compactness and strength – is 0.25 to 0.40 g/cm3. The fabric can also have an anti-stick coating such as PTFE to help more dust be released during pulse cleaning.
The PB line of spunbond fabrics are engineered to bring value and innovation to industrial filtration. Designed for heavy duty applications where clean air and durability are key, these durable fabrics will outlast other medias. They are fabricated with bi-component polyester fibers to resist static and provide high tensile strength.
In a tri laminated non-woven, a meltblown spunbond layer captures dust particles. This is followed by a Needle punched (NP) layer to catch fine dust particles and the last is a color-coded scrim for visual differentiation of different filtration efficiencies.
Spunbond Meltblown Spunbond or SMS, is a nonwoven with a base layer of PP spunbond that has been combined with a middle meltblown layer, and a bottom PTFE membrane. It is water-repellent and can be bonded with resin or thermally. It has high rigidity and air permeability and an excellent dust brush-off performance. It is an ideal material for filter media because it provides the benefits of a flexible structure with good pore size distribution, and it can be easily coated to improve its performance.
Cellulose/Synthetic Blend
Cellulose (/seljUloUs, -kloUs/) is a natural polymer material that can be found in the bark, wood and leaves of plants. It is also used in a variety of other products and applications including textiles, paper, chemical filters and fiber-reinforced composites. Cellulose is a biodegradable and renewable resource that can be grown without the use of pesticides or fertilizers.
The chemical structure of cellulose is made up of long chains of glucose molecules that are joined together by hydrogen bonds. This makes cellulose more rigid than starch and other complex carbohydrates, which have a coiled structure. This is because cellulose has a rod-like shape and gabion basket manufacturers the glucose molecules are attached in an end-to-end manner, which gives it a stiff, strong structure.
Another important feature of cellulose is that it has high adsorption abilities and permeability. Cellulose can be utilised to remove PMs from the atmosphere by a process known as physio-sorption and chemisorption. In physio-sorption, harmful pollutants are drawn to the filter surface by static charge while in chemisorption, the contaminants react with the adsorbent surface or ingrained atoms/molecules in the filter to form simpler compounds.
The type of cellulose used to make a filter can affect its performance. Traditional cellulose, or wood pulp, media has smaller pores which can result in less capacity and efficiency ratings compared to newer synthetic blend medias.
Glass
This filter is a great replacement for traditional sand in your pool filter. It is crushed to the optimum particle size and shape for your swimming pool. The particles have a negative charge to electro-statically attract the pollutants that are then released during backwashing. This reduces the amount of dissolved organic and mineral contaminants and increases your water clarity. It also needs less frequent backwash cycles saving you time and money.
Unlike sand which can become hard and create pressure fluctuations in your filter that cause the loss of clean water, glass will not do this. It also reduces the need for coagulants & flocculants. This makes your filtration system more efficient and saves on maintenance costs.
Cobetter Glass Fiber Filter Paper is an excellent choice for a wide range of laboratory filtration applications. It has low resistance to fluid flow, high load capacity, and excellent chemical compatibility. It is manufactured from borosilicate glass microfibers that are bonded to a PTFE membrane, which gives it outstanding chemical and thermal resistance.
The high surface area of the glass fiber allows for high throughput and the use of lower filtrate concentrations. Additionally, the borosilicate glass is resistant to abrasion and mechanical damage. This is a cost-effective alternative to the traditional cellulose/synthetic blend and provides superior performance in many applications.
