<p>The traditional three-stage wastewater treatment system uses lime clarification, bicarbonation flocculation sedimentation, flocculation and <a href="https://www.lyfilter.com/products" rel="noopener noreferrer" target="_blank">filtration</a> as the major process units. The treatment method will vary depending on the particular sewage that was discharged into the material. Traditional treatment has disadvantages such as complex process, low water usage rate and high chemical consumption. The biological flocs or colloidal substances can't be completely removed so frequent cleaning is necessary, which impacts the effluent quality.</p><p><br></p><p>Rapid economic development and serious degradation of the water environment require urgently the use of appropriate technologies to recycle sewage and wastewater. This field plays a significant role in membrane separation technology. Membrane separation, a high-tech process, has quickly evolved into an industrialized high efficiency and energy-saving separation technique process over the past 40 years. Over the past 40 years, electrodialysis has been advancing in many areas, including medical, electronic, petrochemical and light industries, such as food and beverage, medical and healthcare, micro<a href="https://www.lyfilter.com/products" target="_blank">filtration </a>and ultrafiltration, nanofiltration and pervaporation. It is used extensively in everyday life and environmental protection, and has provided significant economic and social benefits. It is the society's needs that bring membrane technology to life. The demand from society also drives membrane technology's rapid development, technological advancement and perfection. Membrane technology becomes a unit operation and is the key to integration.</p><p><br></p><p>Continuous Membrane Filtration Technology, (CMC).</p><p><br></p><p>Hollow fiber membranes have a high specific area and a high packing density. This makes them compact and easy to produce. Because there is no support layer, they can be cleaned in the reverse order. Hollow fiber membranes are a great choice for large-scale wastewater treatment projects due to their excellent resistance to pollution and resistance against oxidizing cleaning agents.</p><p><br></p><p>CMF technology's core is the high-anti-fouling membrane with the associated membrane cleaning technology. This technology can enable the non-stop online cleaning of the membrane to ensure continuous, uninterrupted processing of liquid and ensure efficient and continuous operation of the equipment.</p><p>CMF is used primarily for the treatment and reuse of raw waters in large-scale urban wastewater treatment plants. It also serves as a pretreatment for large-scale reverse-osmosis or seawater desalination systems. Drink clarification, turbidity and surface water purification are some of the many uses for CMF.</p><p><br></p><p>Membrane Bioreactor (MBR)</p><p><br></p><p>The membrane bioreactor is a combination of biotechnology and membrane separation technology. The membrane is used in wastewater and sewage treatment. The membrane is used to separate solid and liquid. The impurities and sludge are then returned to the bioreactor. Finally, the clean water is drained from the membrane to create a membrane bioreactor. The membrane module's function is the same as the secondary sedimentation tank of the traditional sewage biological system.</p><p>MBR uses a variety of membranes: flat membranes, hollow fiber membranes, and tubular membranes. At the moment, hollow fiber membranes dominate.</p><p><br></p><p>MBR is used to treat domestic sewage. This results in a raw water source that meets a very high standard. MBR technology can be used for water treatment, such as dyeing, scouring, and processing wastewater. The MBR system has another advantage: a small device can be used within a family and a larger device can handle thousands of cubic meters of daily processing.</p><p><br></p><p>Advanced wastewater treatment using integrated membrane process</p><p>The integrated membrane process is a combination of ultrafiltration/microfiltration and reverse osmosis (or nanofiltration) to form an advanced sewage treatment process that can meet the purpose of each reuse. Microfiltration and ultrafiltration can both be used independently as advanced three-stage treatment processes. They are also excellent pretreatment methods for reverse osmosis. The ultrafiltration and microfiltration units have superior anti-pollution abilities and performance and replace complex traditional treatments. Reverse osmosis membranes after microfiltration or ultrafiltration have a longer cleaning cycle than traditional pretreatments. The membrane can last up to 6 years and can be used for as long as 3-4 weeks. The advantages of membrane integrated wastewater recycling include a stable system, low maintenance and low chemical consumption. It also has a small footprint and low operating costs.</p><p><br></p><p>The new hollow fiber ultrafiltration membrane (microfiltration) has superior characteristics to traditional products. It is also more resistant to oxidation and pollution than other types of microfiltration membranes. Low-pressure operation, backwashing, water, and air are all used in the operation process. Flushing, one of the latest technologies in ultrafiltration membrane technology, allows for stable performance in sewage media that has a high tendency to pollute. The ultrafiltration membrane's ability to adapt to complex media environments has been extended to allow for more flexible use. Reverse osmosis is also greatly improved. The technology's application range, its application scope and system application technology are all new. This new generation ultrafiltration membrane brings membrane technology into a new era. Membrane technology can be applied to many complex water quality systems, such as secondary effluent and various raw wastewater.</p><p><br></p><p>Reverse Osmosis Technology</p><p><br></p><p>Reverse osmosis is a membrane separation technology that was developed in the 1960s using pressure as its driving force. This technology was developed by desalinating seawater and brackish waters and is often called "desalination tech". It is rapidly developing because reverse osmosis technology offers many advantages, including no phase change, componentization and simple operation. <a href="https://www.lyfilter.com/high-flow-filter-cartridge" target="_blank">RO</a> technology is widely used in water treatment, including brackish and seawater desalination. It also has applications in ultra-pure water preparation, chemical separat, concentration, purification, and wastewater resources. These projects cover all aspects of electric power, electronics and chemical industry as well as coal, medical, food, and other industries.</p><p><br></p><p>Recycling wastewater serves two purposes: it creates additional freshwater resources, and it protects the environment. Both inorganic series wastewater treatment systems and seawater brackish-water desalination use similar equipment.<a href="https://www.lyfilter.com/high-flow-filter-cartridge" rel="noopener noreferrer" target="_blank"> RO</a> can remove 90% to 99% of copper and lead, mercury, nickel as well as antimony in waste liquids.</p><p><br></p><p>Reverse osmosis is currently used for the advanced treatment urban sewage. Advanced treatment of industrial wastewater has attracted a lot of attention. This includes the reuse of reclaimed water and the advanced treatment for secondary effluents from sewage treatment plant. High-quality water is essential. Many countries in the Middle East are water-scarce and have implemented reverse osmosis technologies to desalinate their water. TDS can exceed 80mg/L in effluent, which increases freshwater resources. Large-scale projects are underway in this area by countries such as Australia, Singapore, and the Middle East.</p><p><br></p><p><a href="https://www.lyfilter.com/" rel="noopener noreferrer" target="_blank">Guangzhou Lvyuan Water Purification Equipment Co., Ltd.</a> specializes in the production of various filter elements, welcome to consult!</p>
