The main treatment unit in conventional systems for surface water is coagulation-flocculation
(CF) process, which consumes huge quantities of coagulant, and produces large volume of …

Drinking water treatment sludge (DWTS) is a by-product of water treatment, and it is difficult
to recycle to high value and poses potential environmental risks. Recycling DWTS into …

Mortar mixtures that consider alternative mineral admixtures are of constant research
interest to reduce ordinary Portland cement (OPC) content thereby lowering final cost and …

The use of alum sludge ash (ASA) in cement-based composites was investigated in this
study, where the cement was replaced by ASA at weight percentages of 0%, 10%, 20%, and …

This paper evaluates the potential of water treatment sludge ash (WTSA) as high-reactivity
pozzolan using strength tests in mortars and techniques to evaluate the calcium hydroxide …

The transition towards a Circular Economy necessitates the development of methodologies
for optimal utilization of secondary resources. One such resource is sewage sludge ash …

Drinking water treatment sludge (DWTS) can be recycled into low-strength concrete blocks
for construction use. The sodium sulfate resistance and leaching behaviours of the DWTS …

The effect of high temperature on the mechanical, durability, and microstructural properties
of mortar containing alum sludge ash (ASA) was investigated in this paper. The ASA was …

This paper investigates AS waste to produce a construction binder of low environmental
impact. It studies the reactivity of AS so that it can be used instead of traditional (higher …

To address the growing global water demand, it is imperative to implement advanced
treatment systems and sustainable alternatives for managing the large amount of waste …
