If the dosage is too low, the pH becomes too high, and it Typical Applications: Industrial and sanitary wastewater. After treatment by the anaerobic system, the water contains biogas containing hydrogen sulphide (H2S). Sulfuric acid is a two normal solution which means that for each mole of sulfuric two moles of H+ or acid are liberated packing twice the punch than an equivalent molar concentration of hydrochloric acid, for example. As a result, chemicals are delivered, handled, stored and dosed at almost every water and wastewater treatment plant under the control of Irish Water. The acid is generally gravity-fed or pumped at low pressure to day tanks. The authors conclude from the results of ninety-nine SWRO membrane autopsies that the use of these commodity chemicals can be beneficial in the pre-treatment system but also can have some serious side effects for the membranes. Advantages of HCI. Dosing pump for sulphuric acid. Compare . From Figure 1, a pH increase from 7.65 to 8.81 equates to 295 ppm of alkalinity increase, which is also equal to 295 ppm of acid use reduction. Read the amount of acid used to reach pH 4.5. It is a colourless, odourless, non-fuming liquid when supplied as a 10 or 5% solution. They argue that sulfuric acid will act as a backup scale inhibitor should the antiscalant dosing pump fail. Acid cost decreases by approximately $210,00 per year and acid usage lowers by approximately 92 percent in this scenario. Here are some process examples you can take advantage of our extensive expertise and experience gathered during the past 50 years: Pre-concentration up to 70 wt%. The problem with hydrogen sulphide is that it converts into sulphuric acid in contact with water, which has a corrosive character.
