Project challenges: The membrane system required frequent cleaning. The desalination capacity and water yield of membrane elements declined rapidly and failed to meet design standards. Solutions: We monitored inlet water quality for 2 consecutive mon...

Project challenges: The recovery rate of the first-stage RO system was only 60%. The membrane elements had short service life, and the desalination rate dropped sharply to 90% after around 2 years of operation. Our technical team conducted on-site in...

Wash fastness is a key indicator of textile quality. Fading and color staining during washing will damage product performance and brand reputation. Feymer develops an innovative integrated process of washing and simultaneous color fixing. High-effici...

In alumina production, slow red mud sedimentation, insufficient underflow density, high suspended solids in supernatant and excessive alkali loss will lead to unstable chemical costs. We optimize both products and production processes. Customized ani...

Mine water is featured with dramatic fluctuation in water volume and quality. Traditional inorganic coagulants require large dosage and have poor anti-interference ability, which often leads to substandard discharge. The compound system of Feymer org...

Traditional mineral processing faces many challenges including high chemical dosage and operating costs. Fluctuated slurry properties will deteriorate overflow water quality and affect concentrate grade and recovery rate. Besides, tailings after sedi...

Most conventional fracturing fluids are emulsion or suspension types with effective content below 40% and poor salt resistance. The dosage has to be doubled when using flowback water, leading to high operating costs. Such products contain over 60% us...

As oil and gas exploitation extends to deep and complex reservoirs, formation temperature and salinity keep rising. Conventional polyacrylamide products suffer severe performance degradation under extreme conditions above 80℃ and 50,000 mg/L salinity...

We provide two technical routes including internal sizing and surface sizing to meet diverse production demands. Internal sizing: Moisblock® ASA / AKD neutral sizing agents matched with Emulamet® special emulsifiers; Surface sizing: Ruize ser...

Intense market competition drives paper mills to reduce the proportion of long fibers and increase short fibers as well as non-fiber raw materials for cost control, which inevitably leads to the decline of paper strength. Specialized strength-enhanci...

Retention and drainage aids serve as core wet-end chemicals in papermaking. They maximize the retention of fibers and fillers to reduce material loss, accelerate dewatering at the wire section, raise machine speed and cut steam consumption, so as to ...
