Initiation of lime use for pH adjustment; Pioneering the development of high rate filtration (2 to 5 gallons per minute/square foot) Building an experimental treatment facility to study water purification methods; Understanding the causes and cures of taste and odor problems in drinking water
The desalinated water is stabilized to protect downstream pipelines and storage, usually by adding lime or caustic soda to prevent corrosion of concrete-lined surfaces. Liming material is used to adjust pH between 6.8 and 8.1 to meet the potable water specifications, primarily for effective disinfection and for corrosion control.
Fresh water can have widely ranging pH values depending on the geology of the drainage basin or aquifer and the influence of contaminant inputs . If the water is acidic (lower than 7), lime, soda ash, or sodium hydroxide can be added to raise the pH during water purification processes. Lime addition increases the calcium ion concentration, thus ...
Settling basins are designed to retain water long enough so that suspended solids can settle to obtain a high purity water in the outlet and to provide the opportunity for pH adjustment. [12] Other processes that could be used: thickeners, clarifiers, hydro cyclones and membrane filtration are highly used techniques in the field. [13]
Advancements in water treatment technology have affected all areas of industrial water treatment. Although mechanical filtration, such as reverse osmosis , is widely employed to filter contaminants, other technologies including the use of ozone generators, wastewater evaporation, electrodeionization and bioremediation are also able to address ...
Despite being described as 'water ionizers', the machines are designed to work as water electrolyzers. [3] This is an electrochemical process in which water is split to form hydrogen and oxygen by an electric current. [1] [18] In some machines, the process produces calcium hydroxide and hydrochloric acid through the use of an ion-exchange ...
The reduction of blowdown by dealkalization keeps the water treatment chemicals in the boiler longer, thus minimizing the amount of chemicals required for efficient, noncorrosive operation. [2] Carbonate and bicarbonate alkalinities are decomposed by heat in boiler water releasing carbon dioxide into the steam.
Beckman Model M pH Meter, 1937 [1] Beckman model 72 pH meter, 1960 781 pH/Ion Meter pH meter by Metrohm. A pH meter is a scientific instrument that measures the hydrogen-ion activity in water-based solutions, indicating its acidity or alkalinity expressed as pH. [2]
