Historically, baryte was used for the production of barium hydroxide for sugar refining, and as a white pigment for textiles, paper, and paint. [2] Although baryte contains the toxic alkaline earth metal barium, it is not detrimental for human health, animals, plants and the environment because barium sulfate is extremely insoluble in water.
Barium Sulfate Scales interfere with fluid flow, enhance corrosion, causes production losses, result in equipment replacement, damage equipment and may host bacteria. Dithiazine Solids Dithiazine solids – formed due to the use of amine-based scavengers – begin to reduce flow within piping and eventually plug off pipelines and towers.

"We use a production process which is unique in the entire world. It is a combination of wet grinding followed by refining" The result: high degrees of brightness and white as well as extreme purity. For industrial use, barium sulfate must be separated from accessory minerals and inherent contaminations in laborious processing steps.
Barium and strontium Sulphate-Scale deposition is usually the result of two different brines co-mingling: one-brine rich in sulphate ions and the other rich in alkaline earth ions. When this happens, the solubility product of the mineral sulphate is exceeded and the water becomes supersaturated. This process is generally responsible for the formation of barium and …

Barium sulfate (barite) is not as common as calcium sulfate and its precipitation is again insensitive to pH [43]. It forms a very hard mineral called barite ( Figure 1.9 ) and can be found in a range of applications and equipment including tanks, pipelines, cooling systems, hot water tanks, and desalination RO membranes [10,12,14] .
