The adsorptive removal capacities for TP using anthracite, biological ceramsite, shale and quartz sand were 85.87, 81.44, 59.65, and 55.98 mg/kg, respectively. Phosphorus desorption was also studied to analyze the substrates' adsorption efficiency in wastewater treatment as well as the substrates' ability to be reused for treatment. It was ...
Ceramsite, as its name implies, is a ceramic particle. Ceramsite is a kind of lightweight aggregate produced by high-temperature calcination in ceramsite rotary kiln.The production process of ceramsite is probably raw material mixing – granulation – Screening – calcination – stacking – transportation.
Shale ceramsite is a lightweight aggregate produced by grinding shale, mixing it with coal gangue and fly ash, adding an expansion agent, and then briquetting …
High-strength ceramsite was prepared by using demagnesium boron mud and oil shale (OS) semi-coke as the main raw materials, Na2SiO3 as binder, and Na2CO3 as ing agent.
This paper studies the proportion of raw materials and process system for firing shale slag ceramsite. The raw materials and raw material ratio of the shale slag ceramsite were determined by the composition analysis of the shale slag; Through basic experiments, it is concluded that when the proportion of raw materials is shale slag: coal …
