Prolonging the life of alumite liquid
Aluminum sulfate separator
With the alumite treatment, the aluminum that dissolves in the electrolytic solution becomes aluminum sulfate, and the required free sulfuric acid decreases and the aluminum concentration increases, so the quality of alumite cannot be kept constant.
Therefore, the current situation is that the applied voltage is increased and a part of the bath liquid is updated regularly.
By introducing this device, it becomes easier to control the aluminum concentration in the alumite treatment tank, and advantages such as quality stability and reduction of new sulfuric acid input can be obtained.
[Advantages of introduction]
■ Reduction of wastewater treatment cost, especially reduction of caustic soda required for neutralization treatment
■ It is possible to reduce the risk of handling strong acids when renewing the electrolyte.
■ In some cases, electrolyte renewal work may not be necessary.
■ Product quality, on-site environmental improvement, and cost reduction can be expected.
■ Can be used as a flocculant as an aluminum sulfate solution
[Device specifications (STANDARD) performance]
■ External dimensions: Vertical / horizontal / height = [1000/500/1600] with casters
■ Operation: 20 minutes / cycle
■ Processing liquid volume: 23L / cycle
■ Waste liquid amount: 23L / cycle
■ Aluminum discharge: 110-115g / cycle (when the aluminum concentration in the bath liquid is 10g / L)
■ Sulfuric acid recovery rate: 80-85%
