Belt filter presses are ideal for dewatering papermaking sludge. Meibang's belt filter presses produce low-water cakes, low operating costs, and high throughput, capable of 24-hour continuous operation. They can be used for both dewatering papermaking sludge and recovering papermaking tailings.

Currently, the papermaking industry leads in wastewater and COD emissions among all industrial emissions, making it the most serious aquatic polluter. Pulping and papermaking wastewater refers to cooking liquor (also known as black liquor or red liquor) generated during chemical pulping, midstream water from the pulp washing and bleaching process, and white water from the papermaking process, all of which pose serious environmental pollution risks. Cooking wastewater is black liquor from alkaline pulping and red liquor from acid pulping. Midstream pulping wastewater is dark yellow wastewater discharged during the screening, washing, and bleaching of the cooked pulp after black liquor extraction. The most serious environmental polluter is the chlorine-containing wastewater generated during the bleaching process. Furthermore, bleaching wastewater contains highly toxic dioxins, a carcinogen that poses a serious threat to the ecological environment and human health. White water is papermaking wastewater, originating from the papermaking process in the papermaking workshop. Wastewater generated by the papermaking industry is characterized by its diverse types, large volumes, and high levels of organic pollutants, making it one of the most difficult industrial wastewaters to treat. This wastewater originates from various stages of the pulping and papermaking process, and its physical properties and concentrations of organic pollutants vary. Therefore, effective treatment processes must be tailored to the specific characteristics of the wastewater. Currently, the main methods used for papermaking wastewater treatment include sedimentation, flotation, adsorption, membrane separation, aerobic and anaerobic biological treatment, and a combination of these processes.
