Papermaking

1. Papermaking industry is one of the 6 main industrial pollution sources in the world. The papermaking wastewater is mostly sourced from the pulping liquor (black liquor), intermediate water, and the white water of the paper machine. The papermaking wastewater may severely pollute the surrounding water, and also cause damage to the ecological environment. This has aroused wide attention of human beings.

2. With the increasing awareness of environmental responsibilities among people, it is extremely urgent to thoroughly solve the environmental pollution resulted from the papermaking wastewater. A belt filter press plays a vital role in the sewage disposal or slurry recovery within the papermaking industry.

3. In Jiangsu Province, a well-known paper mill is capable of dealing with wastewater of up to 24000m3 daily, because it adopts the anaerobic biological treatment process (UASB). The sludge contains a great number of fibers, suspended particles, and poorly biodegradable substances. Therefore, the dewatering performance of a dehydrator is highly demanded. After multiple site visits, this factory purchased three HTB-2000 series belt filter presses from our company in March, 2008.

4. Our clients have been quite satisfied with the water content rate, processing capacity, non-failure operation time, dosage, and other aspects, since the equipment was put into use. Among them, the solid content can reach over 28% after thickening and dewatering, which is superior to the standard demanded by our customers. Therefore, the cost for sludge cake disposal after dehydration is allowed to be dramatically reduced.

5. By cooperating with the large and medium-sized papermaking companies from home and abroad, HaiBar is willing to formulate the most scientific paper–mill sludge dewatering solutions with our customers on basis of the on-site sewage characteristics. Welcome to visit the manufacturing workshop of our company, and also investigate the sludge dewatering sites of our existing customers from papermaking industry.
