MBBR is currently the best water treatment solution for high-strength water systems. This is mainly because of the biological nitrogen removal (BNR), which uses MBBR systems thus improving waste matter quality and increasing treatment capacity with no extra footprint growth. And you can use K1 media and MBBR media to improve water quality in MBBR systems.
The rotary cylinder dryer is a large drying equipment that is directly heated, directly cooled, low-speed rotating, lifting-type material handling, and can form a spiral material curtain to improve the volumetric heat transfer coefficient. When the wet material enters the dryer, it is turned over by the scraper on the wall of the cylinder. As the cylinder rotates, it continuously turns over to form a material curtain. The hot air directly contacts the wet material inside the cylinder for heat exchange, and the moisture is vaporized. According to process requirements, hot air and wet materials can be operated in parallel or in reverse flow. The wet material is discharged from the discharge end of the dryer under the action of the spiral plate and hot air flow. The fine powder entrained by hot air is collected by a vacuum cleaner.
The process principle of the large three-channel drum dryer is a heat drying process. As the dryer cylinder rotates, the internal scraper continuously scoops up the material, forming a material curtain, allowing the material to fully contact with the hot air. The multi-channel structure design more effectively utilizes heat and space, and the residence time of materials inside the dryer is longer than that of single-channel. The unique structural principle means that the product will not be over-dried or under-dried, and the product appearance will be good.
In the city where we live, domestic waste is generated every day. As time goes by, old domestic waste/fresh domestic waste will pile up like a mountain, which not only occupies a lot of land resources, but also causes environmental pollution. Therefore, it is an urgent task to treat and reuse old domestic waste/fresh domestic waste.
