“…A typical textile industry is estimated to produce 5.2-6.6 MLD of textile wastewater through different unit operations [52]. The wastewater from these industries is generally characterized by high COD, color, and total dissolved and suspended solids, which make its treatment difficult [53][54][55]. Although the makeup of textile effluents varies considerably depending on the methods employed and the kind of fibers used, it generally includes a variety of unutilized organic and chemical components, such as dye waste, color residues, acids, alkalis, starch, various kinds of surfactants, cleaning solvents, inorganic salts [56].…”

The textile industry is a growing sector worldwide and has immense opportunity in terms of providing employment and boosting a nation’s economy. However, there exist severe environmental risks associated with textile effluents that impact the surrounding ecosystem. This review offers an approach for sustainable water management using phycoremediation to treat dye-laden wastewater and recover bio-based pigments from the residual biomass. Microalgae such as Chlorella, Scenedesmus, Phormidium, and macroalgae like Sargassum, Enteromorpha, and Codium has been extensively used in several phycoremediation-based studies, and their residual biomass could be a potent source for extraction of bio-based pigments. This review also recommends studies involving the algal-bacterial consortia approach for treating dye-laden wastewater as an alternative to conventional, biobased methods. The outcome of this study will provide policymakers and researchers with new insight to manage water and wastewater resources sustainably. Furthermore, this review also enhances our understanding of nature-based decontamination approaches for treating dye-laden wastewater through algal-based technologies.

“…Such substrates include bamboo wastes (Shen et al 2014 ), oil palm mesocarp (Saidu et al 2014 ), olive wastes and citrus pulp (Panuccio et al 2016 ), corn stover (Schroyen et al 2014 ), napier grass (Lianhua et al 2014 ) and water hyacinth (Lin et al 2015 ; Nkuna et al 2019 ), amongst others. These substrates were selected for anaerobic digestion (AD) to produce biogas based on their chemical composition, wide availability and the challenges they pose on the environment (Shenoy et al 2022 ). In addition to the aforementioned qualities, low lignin content of water hyacinth and its possession of plants’ essential nutrients make it a suitable substrate for efficient production of biogas and soil ameliorant (Njogu et al 2021 ; Barua and Kalamdhad 2019 ).…”

The utilisation of water hyacinth for production of biogas is considered to be a solution to both its control and the global renewable energy challenge. In this instance, an investigation was conducted to evaluate the potential of water hyacinth inoculum to enhance methane production during anaerobic digestion (AD). Chopped whole water hyacinth (10% (w/v)) was digested to prepare an inoculum consisting mainly of water hyacinth indigenous microbes. The inoculum was incorporated in the AD of freshly chopped whole water hyacinth to set up different ratios of water hyacinth inoculum and water hyacinth mixture with appropriate controls. The results of batch tests with water hyacinth inoculum showed a maximal cumulative volume of 211.67 ml of methane after 29 days of AD as opposed to 88.6 ml of methane generated from the control treatment without inoculum. In addition to improving methane production, inclusion of water hyacinth inoculum reduced the electrical conductivity (EC) values of the resultant digestate, and, amplification of nifH and phoD genes in the digestate accentuates it as a potential soil ameliorant. This study provides an insight into the potential of water hyacinth inoculum to enhance methane production and contribute to the feasibility of the digestate as a soil fertility enhancer.

“…Moreover, the water pollution is broken down into groundwater pollution, surface water pollution, sewage pollution, point and non-point source pollution etc [8][9][10][11][12]. Surface water is being tainted as a result of increased human settlements and more stringent treatment is required to make surface water fit for consumption [10][11][12][13][14]. As a result, an additional supply of water is necessary to meet the requirement.…”

Groundwater quality in Noida and Ghaziabad has been decreasing in recent years as a result of industrial operations and pollution. The primary goal of the present work is to investigate the groundwater quality indicators in the various key locations of Noida and Ghaziabad. Different physico-chemical characteristics of groundwater in these locations were investigated in order to quantify the influence of these parameters on the environment in general and human health in particular. pH, total dissolved solids (TDS), Alkalinity, chemical oxygen demand (COD), biological oxygen demand (BOD), total hardness, carbonates, bicarbonates, turbidity and chlorides were measured. pH, TDS, alkalinity, hardness, and chloride content were found to be 7.35-9.05, 0-30 mg/l, 140-975 mg/l, 170-335 mg/l, and 39.90-939.70 mg/l respectively. The acquired results were compared to the permitted limits set by the Indian water quality standard IS:10500-2012 and recommendations were made to improve the water quality of the study region in order to make the groundwater suitable for consumption.
