The amount of sludge depends on the type of treatment, the connected population and population equivalents, and wastewater characteristics. Wastewater characteristics and specific sludge production vary from country to country and from region to region. There is even a difference between urban and rural areas. Sludge production figures range from 20 to 45 kg of dried solids per person per year. The main waste generated in a municipal waste water treatment plant is the wastewater sludge that is removed from mechanical, biological and chemical wastewater treatment processed.dryer machine

Years of neglecting of the sludge issue caused that nowadays sewage treatment factories have to cope with a huge amounts of sludge which has gathered over the years of reckless sludge management. Sludge condensation and dewatering processes are no longer enough to cope with the still growing amounts of sludge or to reach the required standards.

The form of the product obtained after dewatering process is hardly acceptable by several potential clients, including among others agriculture, forestry as well as power industry. Our Technology makes possible energy-efficient, automated, continuous drying of biosolids and production of a Class A Biosolid. Under 40 CFR, part 503 the United States Environmental Protection Agency has published regulations for technologies to further reduce pathogens in Municipal biosolids and to reach Class A biosolids that are safe for the environment. Municipalities now have new choices in the safe disposal of biosolids as opposed to the regulations addressing Class B biosolids. sludge achieve intermediate dryness for composting or incineration reduce disposal cost produce stable and marketable products Increase fuel value.With the increasing demands of construction aggregate, Hongxing sand dryer, sand drying machine has made an rapidly growth in technology, and has made great contribution to development of many mines in the world.

For greater thermal efficiency and where inertisation is required, recycling of exhaust gases can be used. This can be implemented on all our airstream drying systems and retrofitted on customer's existing drying operations. For special applications, the rotary cascade design is adapted to provide a shortfall, or 'Cruciform', lifter configuration. Similarly, Rotary Cascade Coolers and Combined Dryer/Coolers are available as required.
