Challenge
Opportunity


A leading company in the sector of ceramic tiles produces about 37,500 m3/month of effluent from the rectification line.

The treatment was carried out using aluminum polychloride, anionic flocculant and sodium hydroxide for pH correction. The results were unsatisfactory because the high conductivity of the treated water did not allow for total effluent reuse and caused a high degree of equipment wear.

Flox®-QTH was tested in laboratory and subsequently at industrial scale in order to improve effluent quality and eliminate use of hazardous chemicals with environmental impact. The good results obtained led to the successful implementation of the Flox®-QTH and approval for permanent use in the WWTP.

BENEFITS OF THE application
of Flox®-QTH


Conductivity is not affected after application of Flox®-QTH

Production of biodegradable and better quality sludge, which can be reused in the milling process

Reuse of treated water at the plant in 100%

Elimination of the use of alkaline agent (pH remains unchanged after the addition of Flox®-QTH)

Decrease in corrosion and increased useful life of piping and equipment

Improved health and operational safety of the operators through the use of a product not classified as dangerous on the UN list
