The Sludge treatment to solve the sewage problem
Sludge mainly comes from urban sewage treatment plants and industrial sewage treatment plants. It is the waste generated by sewage treatment plants For transportation and subsequent disposal, the sewage treatment plant will not leave the factory until the sludge is mechanically filtered. Generally, the water content is 80% or lower. Sludge is a heterogeneous body composed of organic fragments, ...

Status and future development of sludge drying technology
Sludge drying is the process of removing most of the water in the sludge through evaporation and other actions. The types of drying mainly include solar drying, thermal drying, ultrasonic drying, microwave heating drying and biological drying, among which sludge thermal drying technology is the most widely used and mature technology. The heat transfer medium used in the sludge thermal drying ...

Energy utilization in sewage treatment – a review with comparisons
In recent years, the operating cost of sewage treatment plants (STPs) in some parts of the world has been rising due to increases in the cost of energy. STPs have focused on energy reduction and recovery from treatment processes in order to lower energy consumption. The development involves the improvement of capital set-up for treatment plants in terms of equipment upgrading/plant sizing as ...

Research on Application of Sludge Drying Technology in Sewage Plant
There are many kinds of sludge, mainly including industrial enterprises of sludge, such as electroplating sludge, printing and dyeing sludge, sludge and so on. River, waterworks sludge, sludge, etc. Municipal sludge (also known as sewage treatment plant sludge) is the development and long-term stability of urban sewage treatment, which produces a large amount of sludge, and due to its unique ...

Bio-plastic (poly-hydroxy-alkanoate) production from municipal sewage sludge in the Netherlands: a technology push or a demand driven process?
Valorisation of components from municipal ‘waste’ water and sewage sludge gets more and more attention in order to come to a circular economy by developing an efficient ‘waste’ to value concept. On behalf of the transition team ‘Grondstoffenfabriek’ (‘Resource factory’) a preliminary research was performed for all the Dutch water boards to assess the technical and economical feasibility of ...

LIFE+ Lo2x Project - Case Study
The European Commission’s LIFE+ programme has funded a project to install a sustainable technology for resource recovery from waste treatment – using hydrothermal oxidation (HTO) – at a wastewater treatment facility in Valencia, Spain. What is LIFE+? The LIFE+ environmental research programme is an EU funding initiative to support environment and climate action. ...

Solar drying of sewage sludge - An old method with modern technology using Wendewolf®
Any Sewage Water Work throughout the world will produce sludge, a form of biomass growing in the basins. This biomass has to be evacuated and is, generally speaking difficult to handle! When liquid it has a dry matter of 3 to 4 %, or only 30 to 40 kg per ton of sludge, when mechanically dehydrated to 20 - 25 % most of it is still water, as an average 750 to 800 kg per ton of filter cake. This ...
