Sodium dithionite bleaching solutions for groundwood pulps which require no additional chemicals for pH adjustment prior to direct application to the pulps, based on zinc-derived or formate-derived sodium dithionite and containing small percentages of at least four additives selected from the following:...
The acidity in your vaginal discharge is identified through your pH value, which plays a significant role in your vaginal health. A method to understand your value pH value is through apH scale that measures the acidity of substances,such as vaginal discharge. The pH scale ranges from 0 to 1...
These operating conditions often result in an increased risk of developing either barium sulphate and/or calcium oxalate scale, depending on the operating pH range. This can lead to significant production losses, extra maintenance costs, high bleaching chemical costs and quality issues. Through process...
