Activated Alumina For Water Treatment
Product Introduction
The product is a white, spherical porous material with the property of non-toxic, odorless, insoluble in water and ethanol. The particle size is uniform, the surface is smooth, the mechanical strength is high, the ability of moisture absorption is strong and the ball is not split after absorbing water.
The partical size can be 1-3mm、2-4mm/3-5mm or even smaller such as 0.5-1.0mm.It has larger contact area with the water and specific surface area higher than 300m²/g, it has a big quantity of microspores and can ensure strong adsorption and high defluorination volume to fluorinnion in the water.
Alumina for hydrogen peroxide has many capillary channels and large surface area, which can be used as adsorbent, desiccant and catalyst. At the same time, it is also determined according to the polarity of the adsorbed substance. It has a strong affinity for water, oxides, acetic acid, alkali, etc. Activated alumina is a kind of micro-water deep desiccant and an adsorbent for adsorbing polar molecules. .
Under certain operating conditions and regeneration conditions, its drying depth is as high as the dew point temperature below -40℃, and it is an efficient desiccant for deep drying of trace water. It is widely used in gas and liquid phase drying of petrochemical industry, drying of textile industry, oxygen production industry and automatic instrument air, pressure swing adsorption in air separation industry, etc. Due to the high net heat of the monomolecular adsorption layer, it is very suitable for heatless regeneration devices. Alumina for hydrogen peroxide is white spherical porous particles with uniform particle size, smooth surface, high mechanical strength and strong hygroscopicity. It is made of high-purity alumina through scientific preparation and catalytic finishing. It can be used as a fluoride remover for high fluoride water, making it a molecular adsorbent with a huge specific surface area. When the pH value and alkalinity of the raw water are low, the fluorine removal capacity is high, greater than 3.0mg/g. It can be used for fluorine removal, arsenic removal, sewage decolorization and deodorization of drinking water and industrial devices.
