Ferric Chloride 40% Solution

Ferric Chloride 40% Solution (CAS 7705-08-0, molecular formula FeCl3) is a treatment chemical specified by municipal and industrial plant operators where dose consistency and impurity control directly affect finished water quality. China Chemicals supplies it at 40% w/w in pack sizes from 1 L through to 200 L Drum, so laboratory trial quantities and full production volumes can be sourced from the same specification.

It is also traded as Iron(III) Chloride, Ferric Trichloride, Molysite. Every consignment ships with a batch-specific Certificate of Analysis and the current Safety Data Sheet, and material is stored and picked under stock rotation so you receive product well inside its shelf life.

Typical applications

Coagulant in sewage and industrial wastewater
Odour and hydrogen sulphide control in sewers
PCB and metal etching
Phosphorus removal in treatment plants
Sludge conditioning before dewatering
