What is the classification of sludge in the belt filter press?

Belt filter press in the sludge is the treatment of water and wastewater treatment of different types of sediment produced by the various debris, floating objects collectively. The composition of the sludge, the nature of the main depends on the treatment of non-components, nature and processing technology. According to different classification standards, the belt filter press has a variety of classification methods, the following describes the classification of sludge in the belt filter.
1, according to the belt filter press sludge composition and nature, can be divided into organic sludge and inorganic sludge. Organic matter as the main component of organic sludge can be referred to as sludge. Organic sludge is a hydrophilic sludge. Domestic sewage sludge or mixed sewage sludge are organic sludge. Inorganic substances as the main component of the inorganic sludge is often called sediment, water treatment grit chamber and some industrial waste water physical, chemical treatment of the sediment are sediment, inorganic sludge is generally hydrophobic sludge.
2, according to the belt filter press the source of sludge sludge, can be divided into water supply sludge, sewage sludge and industrial wastewater sludge three categories.
3, according to the process of separation of sludge from the water can be divided into sediment sludge (including physical precipitation sludge, coagulation sludge, chemical sludge) and biological treatment of sludge (refers to the sewage in the secondary treatment process of pollution mud). Most of the sewage treatment plant sludge is a mixture of sediment sludge and biological treatment sludge.
4, according to the belt filter press in the sludge sludge in different stages of classification of the classification, raw sludge, concentrated sludge, digested sludge, dehydrated dry sludge, dry sludge and sludge incineration ash and so on. The method is the most commonly used method of sludge classification.
