Product Description
Polyferric Sulfate(PFS)
Description
Polyferric sulfate (PFS) is a type of inorganic coagulant that is commonly used in water and wastewater treatment. It is a polymeric compound that is formed by the reaction of ferric sulfate with hydrochloric acid, resulting in a complex mixture of polymeric species with varying degrees of polymerization.
PFS is a highly effective coagulant that can be used to remove suspended solids, organic matter, and other impurities from water and wastewater. It is particularly effective in the removal of colloidal particles and organic compounds that are resistant to other treatment methods. PFS works by destabilizing the colloidal particles, allowing them to aggregate and form larger flocs that can be more easily removed by sedimentation or filtration.
In addition to its coagulation properties, PFS also has some disinfection properties that can help to reduce the bacterial content of the treated water. It is also relatively stable and has a long shelf life, making it a convenient and cost-effective option for water treatment.

Company Profile
Lanyao was established since 1998,in the start-up stage, as a watertreatment chemicals distributor, we provided product sales and technical supports for various regional sewage plants in East China.
Since Eastern China has always been a concentrated area for the development of light and heavy industries in the early 20th century, the water qualities of sewage plants in various regions are relatively different and complicated so that the treatment is relatively difficult. Therefore, we usually send technicians to the site and conduct micro-experiments based on detection report on COD,BOD,SS,ammonia nitrogen,total phosphorus,heavy metal and other impurities.As that we can match the appropriate type of chemicals to obtain the best treatment effect.
Until 2006, according to nearly ten years of technology accumulation and research on various types of chemicals, cooperating with experts and professors from various colleges and universities, Lanyao manufacturing-type enterprise was settled in yixing, jiangsu province.
Lanyao produces a wide range of chemicals used in water treatment processes, including coagulants, flocculants, PH adjusters such as polyaluminium chloride, poly ferric sulphate, sodium acetate and polyaluminium ferric chloride, etc. The company is now located in the Chemical Industry Zone in Jiangsu Province, with a factory area of 17,000 square meters and 108 employees.
We have a complete set of production management and quality control systems. We got the 1SO9001 quality system certification in 2012, the ISO14001 environmental system certification in 2014, and the occupational health and safety management system certification in 2016. The company has both advanced equipment and talents, domestic advanced testing equipment, and over 30 years of professional and technical personnel with intermediate and senior titles. In addition, the company has a professional transportation team, and owns 10 liquid PAC tankers and 5 vans, which can fully guarantee the timeliness of product supply.
