Wastewater treatment (1)

Wastewater treatment methods use physical, chemical and biological methods to treat wastewater, purify wastewater, reduce pollution, and even achieve wastewater recovery, reuse, and full use of water resources. Wastewater type Domestic wastewater Domestic sewage refers to the wastewater discharged by people in daily life activities. This kind of wastewater is mainly polluted by domestic waste […]

Loss on ignition (2)

The loss on ignition test method has different regulations in the technical standards of different industries. For example, the test method for the loss on ignition of ash formed by combustion is as follows: accurately sample 0.5~1 which has been dried at 105~110 °C. Gram, placed in a constant weight platinum crucible, burned on an […]

Loss on ignition (1)

Definition Loss of ignition (LOI Loss on ignition) refers to the raw material that loses external moisture after drying in the temperature range of 105-110 ° C. The mass lost after burning for a long time under certain high temperature conditions accounts for the mass of the original sample. percentage. The high temperature environment here […]

Adsorption type

  The adsorption type of activated carbon is different according to the adsorption force of the solid surface. The adsorption can be divided into three types: physical adsorption, chemical adsorption and ion exchange adsorption: Physical adsorption The adsorption of the adsorbent and the adsorbate (solute) through the molecular force is called physical adsorption. This is […]

Activated carbon adsorption

  System of law Activated carbon is made by activating carbonaceous materials such as wood, coal, and husk under high temperature and anoxic conditions, and has a large specific surface area (500-1700 m2/g). The activated carbon used in the water treatment process is powdered carbon and granular carbon. Powdered carbon is suspended by adsorption, while […]

Filter classification

  Initial effect plate filter As a pre-filter in the empty net system, it protects the medium and high efficiency filters of the latter stage. If the real high-efficiency filter is not protected by the primary and medium efficiency filters, the scrapping time will be extremely short. Medium efficiency bag filter As an intermediate filter, […]

The filter levels

How many levels does the filter have? Some people who think about it will think of high-efficiency air filters. The word “efficient” is purely a rhetorical slogan? Is there an “inefficient air filter”? It’s really true, it’s also a filter, it has different uses, and naturally there are different filter levels. Among them, we currently […]
