Hydroxochloride aluminum brand “Metapak” (aluminum oxychloride)
China standard: GB 15892-2003 To clean cold water (also during flood periods) we offer solid, highly basic aluminum hydroxychlorides (MetaPAC, China). Their AI2O3 content is up to 30%. A.V.Dumansky Institute of Colloid and Water Chemistry performed full elemental analysis of MetaPAC samples. Fields of use: – cleaning and conditioning of drinking water; – wastewater treatment for industrial, agricultural and household purposes; – water treatment at TPPs, regional power stations, boiler plants; – in the paper industry for sizing of paper. Advantages: – high rate of flaking; – technological activity virtually independent of the treated water temperature; – low concentration of residual aluminum in cold water; – no formation of toxic substances in water, air and soil; – long shelf life; – no compacting when stored in sealed package; – no need for storage in heated warehouses and premises; – easy to use, quickly and easily soluble in water; – exact dosing. Dosage: 1. In dry form using a feeder. 2. In dissolved form: to prepare 100 ml of 1% aqueous solution, 3.39 g of powder is dissolved in 98.31 ml of water. The concentration of the resulting solution can be determined by the standard GB 15892-2003. The recommended dose is determined by test coagulation. Packaging: supplied in sealed 25 kg polypropylene bags with polyethylene liners or in 1000 kg big bags. Transportation: any mode of transport. Storage: MetaPAC can be stored in warehouses, hangars, sheds, heated and unheated areas in untampered sealed packaging. Recommended storage temperature range: from -30 °C to +40 °C. After opening, the reagent should be fully used to prepare working solutions; any unused product should be re-sealed for subsequent storage. Shelf life: min. 12 months.
