Abstract:

The textile industries are essential to the economy of Bangladesh. This sector is the largest foreign exchange earner for the country, employing over three million women. However, the unplanned and rapid clustering of industries harms the environment. Unabated untreated textile wastewater discharge is plaguing the water bodies. Compliance issues arise due to the high treatment costs associated with expensive imported chemicals and energy-intensive systems. In the pursuit of a sustainable solution, a pilot-scale technology development project was initiated at an operational textile wastewater treatment plant. The process involved the chemical oxidation of treated wastewater using calcium hypochlorite, followed by rapid sand filtration with the assistance of waste blast furnace iron slag. This approach resulted in the complete removal of colour and further reductions of 95% for COD, 93% for TDS, and 89% for TSS, ensuring that the treated water met Bangladesh's discharge standards. Consequently, this water can be reused in textile wet processes. Fabrics dyed with recycled water exhibited comparable colour fastness in dry and wet conditions. The developed tertiary treatment process, relying on locally available resources and technology within the regional supply chain, holds the potential to serve as a sustainable wastewater treatment option for textile industries in resource-challenged economies. This approach aligns with the objectives of sustainable development by embracing circular economy principles.

La gestione sostenibile delle acque reflue derivanti dalla lavorazione tessile rappresenta una sfida cruciale per le economie con risorse limitate. L'approccio innovativo che combina l'ossidazione con ipoclorito di calcio e la filtrazione con sabbia arricchita di scorie di ferro di altoforno si distingue per la sua efficacia nel trattamento delle acque reflue. Questo metodo non solo riduce l'impatto ambientale, ma consente anche di riutilizzare l'effluente trattato nei processi umidi, ottimizzando così l'uso delle risorse idriche.

Many countries in the world are facing the problem of wastewater treatment and are still having a flaggle lot of difficulties in this issue, it is interesting that today I saw an article sharing about this issue and was very happy to read it.

This is a fascinating example of how innovation can address environmental challenges in resource-limited settings. The use of locally sourced materials like blast furnace slag is particularly impressive. Do you think this pilot project could be easily scaled up and implemented across other textile factories in Bangladesh, and what are the potential barriers to widespread adoption? It reminds me of the challenges faced when I get a high score in the Dinosaur Game.
