сульфат аммония

Fertilizer — The primary use of Ammonium Sulfate is as a fertilizer for alkaline soils. In the soil the ammonium ion is released and forms a small amount of acid, lowering the pH balance of the soil, while contributing essential nitrogen for plant growth.

Food Additives | Acid Regulator (E517) — As a food additive, Ammonium Sulfate is considered generally recognized as safe (GRAS) by the U.S. Food and Drug Administration, and in the European Union it is designated by the E number E517. It is used as an acidity regulator in flours and breads.

Treatment of drinking water — In the treatment of drinking water, Ammonium Sulfate is used in combination with chlorine to generate monochloramine for disinfection.

Selection Criteria for SHS & CONTURBEX

Key factors
Solid concentrationRelatively constant feed conditions with solids concentrations starting at about 40%.Very safe operation even with fluctuating solids concentrations due to forced solids transport.
Product washingHighest product purities due to the long residence time of the product on the screen.Good, but somewhat limited product purity due to shorter dwell time.
Solid throughput / yieldSmooth product transport, large solid cake height - and consequently less particle breakage - reduce solids losses to the filtrate and increase the yield.Thinner solids layer provides rapid dewatering, but may result in more particle breakage and higher solids losses.
Application often in the separation of fine ammonium sulfate crystals.
Residual moistureOptimal dewatering of the crystals even at lower G-force and after a product wash due to long residence time on the screen.Higher G-force ensures fast and optimal dewatering even with finer crystals.
CleaningThe product remains in the screening drum after the feed stop. Unloading of the machine before restart by automated cleaning.Self-cleaning effect due to the scroll - minimal residual amount of product remains in the screening drum after the feed stop. Machine can be cleaned even after a restart.
Sealing systemVapour- and gas tight execution available.Vapour- and gas tight execution available.
