Turn-key project of sludge solidification unit for the Waste Water Treatment Plant

Realization: 2009 – 2010

Subject matter and scope of services:

• Design works – providing technology and know-how, basic and detail design of complete line with process piping – compressed air, drinking water and industrial automation system,
• Supply of equipment such as tanks, silo, conveyor, pumps, mixer, automation,
• Erection of equipment and pipelines, cabling, cable routes, electric cabinets and control panels.

The project’s objective was to design the installation for sludge solidification. The scope of work included construction of the project along with the technological “know-how”, delivery of equipment, development of design in many branches, project executive, erection of complete installation, commissioning, start-up and training of personnel.
Installation task is to convert the sludge in form of suspension, as a result of leaching of chemical products formed during the combustion of sludge in  Sludge Incineration Plant to vibrated blocks consisting of filtered sediment and a binder which is cement. Suspended sediment after leaching contains a significant proportion of heavy metals, and therefore a necessary condition was to use technology that will prevent contaminants leaching from the material by rain and snow to the environment during its storage. Therefore Dabster decided to use technology through the formation of sludge solidification it in blocks, which, after appropriate performance indicator met the requirement of leaching of pollutants permitted by the standards and the possibility of storage of non-hazardous landfills.
