Challenges in textile wastewater and current palliative methods: An overview
Effluents from dye and textile industries are highly contaminated and toxic to the environment. High concentrations of non-biodegradable compounds contribute to increases in biochemical oxygen demand (BOD) and chemical oxygen demand (COD) of the wastewater bodies.

Summary: | Effluents from dye and textile industries are highly contaminated and toxic to the environment. High concentrations of non-biodegradable compounds contribute to increases in biochemical oxygen demand (BOD) and chemical oxygen demand (COD) of the wastewater bodies. Dyes found in wastewater from textile industries are
carcinogenic, mutagenic, or teratogenic. Biological processes involving certain bacteria, fungi, activated carbon, and carbon nanotubes (CNTs) are promising methods for treating the wastewater. These methods are either inefficient or ineffective. These complexities necessitate a search for new approaches that will offset all the shortcomings of the present solutions to the challenges faced by textile wastewater management. This
article reviews the past and recent methods used in the treatment of textile dye wastewater and future opportunities for efficient treatment of textile wastewater.
Sisa daripada pewarna dan industri tekstil telah mengakibatkan pencemaran
yang teruk dan pembuangan toksid kepada alam sekitar. Kepekatan tinggi pada kompaun
bukan bio-kitar semula menyumbang kepada peningkatan permintaan bio-kimia oksigen
(BOD) dan permintaan kimia oksigen (COD) pada sisa air buangan. Pewarna yang
dijumpai daripada industri kain adalah karsinogenik, mutagenik atau teratogenik. Proses
biologi melibatkan sesetengah bakteria, kulat, karbon diaktifkan dan karbon nanotiub
(CNTs) merupakan kaedah-kaedah yang dijanjikan untuk merawat sisa air. Kaedahkaedah
ini samada tidak efisien ataupun tidak efektif. Ia memerlukan pencarian kepada
pendekatan baru yang akan menghilangkan semua kekurangan pada solusi terkini kepada
cabaran-cabaran yang dihadapi dalam pengurusan air sisa buangan kain. Artikel ini akan
mengulas kaedah-kaedah terdahulu dan terkini yang telah digunakan dalam pengurusan
air sisa buangan pewarna kain dan peluang akan datang bagi mendapatkan pengurusan
yang cekap pada air buangan sisa tekstil. |
