The company was named the 2007 "Wenzhou patent demonstration enterprise."

(2) scientific research and application

Products produced by the Company in 1990 the National Environmental Protection Agency (ministerial) Science and Technology Progress Award and the State Pharmaceutical Bureau of Zhejiang Province Science and Technology Progress Award in 1994 as a national new product, the State Science and Technology Commission for as Eighth and the Ninth Five-Year Plan "period, the national scientific and technological achievements to promote projects, the State Environmental Protection Administration as the best practical promotion of technology.

PGH series of activated carbon precision filtering machine "scientific and technological achievements in 2004 by the provincial (ministry) level identification, and was named the Lucheng District, Science and Technology Progress Award in 2004, was named to the Wenzhou Municipal Science and Technology Progress Award in 2005, 2006 Science and Technology Department of Zhejiang Province is identified as "high-tech products.

Ultrafine metal powder filter pressure washing to dry one "scientific and technological achievements in 2005 by the provincial (ministerial) level identification, and was named the Lucheng District, Science and Technology Progress Award in 2006, the Science and Technology Department of Zhejiang Province in 2006 was identified as" high-tech technology products ", 2007, was named Wenzhou Municipal Science and Technology Progress Award in 2007 was named Zhejiang Federation of Industrial Machinery Science and Technology Progress Award, 2006 as National Torch Plan Project in April 2008 acceptance, as a provincial Innovation Fund project in 2007.

Alkali saline precision microporous thin layer filtration process "was named the 2007 Science and Technology Progress Award, Lucheng District.

Horizontal ultra-fine powder filtration and washing machine pressure dry was rated as a major technology project of the Lucheng District, was named the Lucheng 2009 Technology Progress Award.

The large nickel electrolyte filter as Lucheng major technology project.

Filtration and washing of the rare metal ultrafine powder recycling technology and equipment "in February 2011 by the Ministry of Science and Technology SME Technology Innovation Fund project, and 60 million in financial support.

My company is one of the outstanding environmental protection enterprises in Zhejiang. Tech SMEs in Zhejiang Province, the company's technology research and development center Lucheng District People's Government in 2006 identified as "enterprise technology research and development center" in 2003 won two consecutive terms in 2008 and in 2011 won the national high-tech enterprises. The company attaches great importance to personnel development and training of personnel of the follow-up. In recent years, continue to introduce tertiary institution graduates in the formation of a bring together the combination of R & D team. Senior titles of the total number of employees 2 O%.

Focus on product quality, strengthening the product pre-sales, after-sales service, the company's products dominate the precision filtration industry, technology and market share, the product has been covering the whole country (except Tibet) in various provinces, and exported to Southeast Asian countries.

In order to meet user demand for the product, relying on their own strong technical force constantly develop new products for the user. Precision solution filtration system, filtration and washing of the ultra-fine powder pressure machine dry metal powder, the product of choice of the rare earth equipment production, 09 environmental companies of Shell Canada Kang Shifu's production of three sets of ionic liquids, precision filtration system, good usage. Glyphosate production of filter is a major problem in pesticide production industry, after many years of technology development, in 2007, after testing, were successful, the majority of users welcomed. Central South University to jointly develop a new type of ion exchange in the nonferrous metals industry has been budding. Large Medical chromatography can replace foreign products, the products have been widely used in the domestic pharmaceutical companies, saving a lot of foreign exchange for the country.

Credibility is the cornerstone of enterprise development. My company has always attached great importance to the integrity management, contract, keeping promises, for several years, the Agricultural Bank of China as credit AAA grade enterprise, was named to the AAA level of Industry and Commerce Administration of Zhejiang Province in 2006 Shou contract re-credit units in 2007 and 2008 continuous identified as AAA grade credit enterprise by the Zhejiang Rural Credit Union, has been named the Zhejiang industrial and commercial enterprise class AAA credit units Lucheng integrity of the first batch of 100 enterprises in Zhejiang Province Agricultural Bank "AAA grade credit enterprise" .
