There are many ways to remove microorganisms from water and wastewater. Each of these filtration processes has their own application and benefits that make them unique in their own right. As filter presses technology improves, membrane filters play an important role in dewatering, desalination, enhanced oil recovery (EOR), treatment of municipal and industrial wastewater, as well as producing high-quality water for several uses. There are different types of Membrane filter press flat sheet membrane press, tubular membrane press, belt-filter press and pleated drum press. Depending on your flow rate requirements and media selection, membrane filters have a wide range of capacities and capabilities.
Membrane filter press manufecturing
The simplest application of membrane filtration technology in industrial processes called membrane separation, or simply membrane filtration. This technology applied to concentrate various types of liquids, as well as gases and vapors. A common process using a membrane filter press includes organic membranes such as polyamide and cellulose, in conjunction with selectable transducer-type modules (for example: diaphragm pump, squeeze pump) capable of pumping liquid substances containing suspended particulate matter through pressure chambers defined by those membranes. Such membrane separation technologies are widely utilized for filtering air in food processing facilities, medical laboratories and clean rooms where aeration may be required at ultra-low pascal values.
Water purified by membranes can be in any forms of water treatment processes. It mostly used in raw water, seawater desalination, industrial waste water treatment etc. It depends on physicochemical characteristic for choosing membrane type and treating application. For example, reverse osmosis membrane usually applied to waste water with high salt concentration and no contaminants. Ultra filter press manufacturers can be chosen for purifying brackish or fresh water with very high turbidity as well as heavy metal ions in it. The separation efficiency will get better under clean condition and lower flow rate.
How does membrane filter press work?
In a membrane filter press, both liquid and gas phases separated across an ultra-fine filtration membrane. This technology allows you to use low pressure in your filtration system (which means reduced energy consumption) while producing high-quality clean water, or hydrocarbon and biofuel product streams at high purity. A membrane filter press can handle solids that range from fine powders and sludge to large chunks of biomass feedstock; simply choose a filter press with sufficient filter area to handle your application needs.
Tips for installation and operation of membrane filtration system
There are three basic types of membrane filtration systems: tangential flow, cross flow and hollow fiber. Depending on what kind of chemical being filtered, a good choice can improve production efficiency. save energy and get high quality products. It always recommended to ask for help from professionals when choosing and installing a filter press system . because they not only find an ideal solution but also ensure that it runs efficiently.
When designing a Membrane Filter Press system, it important to decide how large and powerful of a membrane filtration unit you will need. To do so, take into account what kind of contaminants your water source has and what its average flow rate will be.
It’s also wise to check with your area’s government agency that regulates drinking water quality in order to see if there are specific regulations or treatment recommendations for whatever contaminants are present in your local water supply. Once you have all of that information, you can create an effective Membrane Filter Press design for maximum efficiency and results.
Before using membrane filtration system, it necessary to do some preparatory work such as calculation and equipment designing. Since Membrane Filter Press technology is developing rapidly and there many kinds of membranes with different features on market, first you should know its principle and figure out which one fits your requirement best. If these operations done in advance, there fewer problems arising from unexpected factors during operation. Therefore, you should choose a company that offer customized design for your project rather than just providing standard machine for all customers. This will not only help save energy but also reduce pollution caused by overloading system unnecessarily.
