This study evaluates the recovery of sulfuric acid from a 15 wt% H₂SO₄ feed stream using diffusion dialysis (DD). The DD process operates through a concentration-gradient-driven membrane separation mechanism using an acid-resistant anion exchange membrane. During operation, acid species selectively migrate from the acid feed side to the water side, producing a recovered acid stream, while most metal ions, salts, and impurities are retained in the raffinate stream.

This article is structured as a narrative technical review combined with a laboratory case study. It first summarises the electrochemical mechanisms and operating parameters that control treatment, then interprets a methylene-blue and sodium sulfate solution decolourisation test performed with the YASA laboratory electro-oxidation system. The case study is intentionally treated as a screening demonstration rather than as proof of complete pollutant mineralisation.

Cutting fluid is a specialized industrial fluid used during metalworking operations such as machining, milling, drilling, grinding, and stamping. Its primary functions are to cool, lubricate, clean, and protect both tools and workpieces during processing.

In this article, we explore the main pollutants found in textile effluents, the environmental impacts of untreated wastewater, and the most effective textile wastewater treatment technologies used today.

At YASA ET, we’re proving that wastewater is not waste; it’s a valuable resource. Our innovative technologies and advanced treatment processes are transforming polluted water into clean, safe drinking water, contributing to environmental sustainability and water security.
