"Lisheng water purifier" was founded in 1992, is a specialized in water treatment science and technology research, separation membrane technology and products, home water purification equipment research and development, production, sales and service of high-tech enterprise groups. Lisheng has undertaken the National Torch Program, the National "Tenth Five-Year" Science and Technology Tackling Program, participated in and undertaken the National 863 Program, the National "Eleventh Five-Year" Major Science and Technology Special Project (Water Special Project) and other scientific research tasks, and has obtained fruitful scientific research results. In the "Tenth Five-Year" Science and Technology Tackling Program, Lisheng successfully developed "PVC alloy capillary ultrafiltration membrane", which solved the world problem of industrializing the production of high-quality ultrafiltration membranes made of ordinary PVC materials, reduced the production cost and operating energy consumption of ultrafiltration membranes, improved the filtration performance and service life of ultrafiltration membranes, and strongly promoted the development of ultrafiltration membranes, and also improved the quality of ultrafiltration membranes. It has reduced the production cost and operating energy consumption of ultrafiltration membranes, improved the filtration performance and service life of ultrafiltration membranes, and vigorously promoted the large-scale application of this technology in traditional water treatment industry. This achievement has won the national "key new product certificate", "Science and Technology Award" of Hainan Province and "China Membrane Industry Association Science and Technology Award".
"Lisson water purifier" in Haikou built ultrafiltration membrane production base, the annual output of 3 million PVC and PVDF capillary ultrafiltration membrane. "Lisson has a large-scale "ultrafiltration equipment" production base in Suzhou, with an annual production capacity of about 500,000 sets of column and curtain ultrafiltration membrane modules, small ultrafiltration equipment, home and commercial water purifiers.
"Shanghai Lisheng water purifier" products are widely used in municipal water supply, production water treatment, sewage treatment and its reuse, urban household drinking water purification, rural water reform, public **** place direct drinking water and other fields, exported to more than 40 countries and regions around the world, including Coca-Cola, McDonald's, Toyota, Ebara, Intel, LG and other world's leading companies, McDonald's, Toyota Motor, Ebara, Intel, LG and other Fortune 500 companies around the world, including more than 600 enterprises and projects have been applied, and more than 500,000 home users.
Liters of ultrafiltration membrane module for municipal water supply treatment, running energy consumption and traditional processes, investment is lower than the traditional process, than the traditional process to save 75% of the land, water savings of 3 to 5%, but can completely filter out bacteria and viruses, microorganisms and turbidity and other indicators than the U.S. and the European **** body standards, to become the "third generation of tap water treatment process. It has become the core technology of "the third generation of tap water treatment process". The Kaohsiung Water Treatment Plant in Taiwan, with a daily output of 300,000 cubic meters of purified water, adopts Lifesun's ultrafiltration membranes, marking that Lifesun has stepped into the forefront of the same industry in the world in the field, and the plant has been running successfully for 3 years as of October 2009, becoming a model for solving the problem of high-pollution and high-variation water quality treatment in the field of global municipal water supply. in November 2009, the Nanjiao Water Treatment Plant in Shandong Province, adopting Lifesun's immersion PVC alloy ultrafiltration technology, became the first water treatment plant using domestic ultrafiltration membranes. In November 2009, Dongying Nanjiao Water Plant in Shandong Province adopted the submerged PVC alloy ultrafiltration technology of Lifesun, becoming a large-scale membrane water plant with domestic ultrafiltration membrane technology.
LISI ultrafiltration membrane module for wastewater treatment, treatment process is short, the quality of produced water is good, and biodegradation, reverse osmosis and other technologies used together, can efficiently deal with a variety of wastewater. This technology has been successfully applied to oilfield recovery and reuse, urban waste leachate treatment, community sewage treatment, as well as printing and dyeing, slaughtering, tobacco and other industrial production of wastewater treatment and reuse process, by the State Intellectual Property Office awarded the "energy-saving and emission reduction recommended products" title. Lifeng PVC alloy ultrafiltration membrane bioreactor is used in the rainwater treatment and reuse project of the Future Pavilion of the Shanghai World Expo, and all the water is reused in the landscape water of the park.
In 1998, LISI introduced ultrafiltration technology into the field of home water purification, and developed a variety of combination processes with ultrafiltration as the core, to completely solve the problem of secondary pollution caused by the water pipeline transportation process. "LISE whole-house water purifier "system" changed the traditional water purifier can only solve the drinking water problem, the filter cartridge is easy to be dirty and clogged defects, a strong impetus to the popularization of water purifiers in China's urban households. LISI products are also widely used by catering enterprises, factories, mines, schools, organizations, for business water, public **** direct drinking water purification. 2010, LISI undertook the Shanghai World Expo Expo Park all the direct drinking water facilities construction and maintenance work for about 70 million visitors from around the world to provide a high standard of direct drinking water.
LISI's small ultrafiltration equipment is small in size, produces good water quality and has a high degree of automation, which can be fully adapted to the dispersed rural areas, poor sanitary conditions, backward management level and other characteristics, and has been vigorously promoted in the rural water reform project.
The field water purification vehicle with LISI's ultrafiltration machine as the core filtration equipment is equipped with 260 regiments of the whole army, and LISI's R & D and manufacturing of the manned water purifier is adopted by the People's Liberation Army. 2008 August, the Olympic emergency water supply vehicle with LISI's ultrafiltration machine as the core filtration equipment also played an emergency safeguard role in Beijing. At the same time of rapid development, LISHEN always keep in mind the social responsibility of water purification enterprises. Following the 1998 flood donated 1.4 million yuan worth of ultra-filtration equipment, in May 2008, LISE donated 11 water purification stations in the disaster areas in Sichuan, and donated 2000 sets of portable water purifiers, more than 40 employees in the time of crisis deep into the disaster area for up to 3 months, for the people of the disaster area to send clean and safe drinking water. 2009, August, the "swan" typhoon struck the city. In August 2009, the "Swan" typhoon struck Danzhou, Hainan, Li Sheng donated more than 300,000 yuan of water purification equipment to the disaster area to ensure that the people in the disaster area drinking water safety.
