Comprehensive Utilization of Sludge: A Magnificent Transformation from Waste to Resource

In the closed-loop chain of sewage treatment, sludge, as the final product, has long been regarded as a formidable environmental burden. Statistics show that the annual output of municipal sludge in China has exceeded 60 million tons (calculated at 80% moisture content), and the volume of industrial sludge is even more substantial. However, with the deepening of the concept of resource recycling and technological innovation, sludge is gradually shedding its label as "waste." It is reentering production and daily life in new guises such as energy sources, building materials, and soil conditioners, embarking on a journey from the end of pollution treatment to the forefront of resource utilization.

Treatment of Palm Oil Mill Sludge: A Comparative Analysis of Co-Treatment and Separate Processing with Regional Insights from Southeast Asia

Palm oil mill sludge (POMS) management remains a critical challenge for the palm oil industry, particularly in major producing countries like Thailand, Malaysia, and Indonesia. POMS typically consists of two distinct types: flocculant-laden sludge (generated from chemical coagulation processes in wastewater treatment) and flocculant-free sludge (derived from primary settling tanks). This article explores the technical and operational considerations for co-treating or separately processing these sludge streams, alongside regional practices and future sustainability trends, with a focus on integrating innovative technologies like TDG TIC Technology’s disc-type sludge drying technology for enhanced efficiency.

After Co-Incineration of Sludge with Municipal Solid Waste: How to Treat the Burned Ash?

I The Integration of Waste Incineration and Sludge Treatment Municipal solid waste (MSW) incineration is a common waste management method that reduces waste volume and recovers thermal energy. Meanwhile, sewage sludge from wastewater treatment plants contains high organic matter and moisture. Direct landfill not only occupies land but also risks groundwater contamination. Thus, co-incinerating sludge with MSW has emerged as a viable solution.

Technical Analysis of Three Core Components in Sludge Drying Equipment

In sludge reduction, harmless treatment, and resource utilization, the disc dryer, dust collector, and condenser form the core "troika" of drying systems. These three components work synergistically to optimize the entire process of sludge dehydration, dust control, and waste heat recovery. This article provides an in - depth analysis of the core value of these three devices from the perspectives of technical principles, functional characteristics, and system collaboration.
