A Sludge Incineration Plant designed to process 250 cubic meters of sludge per day

As part of the 24 Mega Projects for Ulaanbaatar City Development, a Sludge Incineration Plant with a daily capacity of 250 cubic meters will be built in 2025-2027. The Plant will dewater and dry sludge from both the New Central Wastewater Treatment Plant of Ulaanbaatar City and domestic sources prior to incineration. This process will contribute to the reduction of soil and water pollution.

The facility is designed to process 250 cubic meters of sludge per day, converting it into approximately 5–6 cubic meters of ash. In other words, the Sludge Incineration Plant is expected to handle 238 tons of sludge daily, with a total sludge reserve projected at 843,200 cubic meters. The project site will encompass approximately 40,000 square meters and is planned to be situated in front of the New Central Wastewater Treatment Plant of Ulaanbaatar City.

-Following deep processing and dewatering, both domestic and industrial sludge from Ulaanbaatar's water treatment facility will undergo incineration.

-Legacy sludge will be pre-filtered and dried prior to combustion.

-The gas generated during incineration may be utilized for power generation, while low-pressure steam can serve as a thermal source for the drying process.

-The ash produced during gas purification will be buried and repurposed as construction material. The Sludge Incineration Plant is specifically designed to simultaneously treat both sewage sludge and associated odors.

Specifications for the sludge incineration plant:

• Both sewage sludge and odor are handled simultaneously.
• A fluidized bed incineration is employed in the incineration system.
• The incineration system can be adapted to a wide range of material properties.
• There is a facility for cleaning air gas.
• Low-carbon building methods are used for the operation.
