Water Management In Textile Industry: Technical And Economic Aspects

Textile industry is an intensive water use sector. Consequently, enormous quantities of wastewater are generated from different manufacturing processes. Numerous opportunities for water reuse could be exploited by rational management of water use and reuse via segregation and upgrading of specific effluents using membrane filtration systems comprising ultrafiltration (UF) and reverse osmosis (RO). This paper is an endeavor to develop technoeconomic indicators for extended water reuse applications in textile industry using UF and RO. Extensive data gathered from a typical Egyptian dye house have been utilized to rationalize water use and reuse management based on different levels of pollutants in waste streams. A developed rationale enabled the identification of four applicable intervention scenarios comprising three reuse scenarios ranging from limited reuse (about 25%) to maximum reuse (about 87%) and a total end of the pipe treatment scenario. The financial assessment for a typical wastewater load (about 3500 r m/day) reveals that the maximum reuse scenario comprising UF, two stage RO in addition to direct use and low press RO is the most preferred one. Further, sensitivity analysis indicates that the annual cost of the total end of pipe treatment scenario will equal the annual cost of the maximum reuse scenario when the unit cost are US$ 0.5, 0.43 and 0.3 per cubic meter for wastewater treatment, RO and UF respectively.

Potential for wastewater reuse in irrigation: case study from Aden (Yemen)

Wastewater treatment with waste stabilization ponds (WSP) is a very efficient, low cost and low maintenance operation. The treated wastewater from WSP should be considered as a valuable resource for reuse by water resources managers. Yemen’s water resources are currently experiencing a crisis, because all surface water and groundwater resources are exploited beyond the level of recharge. Promoting water reuse of treated wastewater for irrigation could mitigate this water crisis. This paper assesses the performance of a WSP in the city of Aden by examining the quality of treated sewage predominantly of domestic origin. A comparison with international guidelines reveals that it is possible to use the final effluent to a limited extent in irrigation. This paper includes an outline of the social, religious and political reasons for the water crisis, and explores the idea of reuse of effluent for different irrigation practices.     

Wastewater reuse potential analysis: implications for China's water resources management

It has been recognized that wastewater reuse or reclamation serves as an efficient and valuable way to cope with the scarcity of water resources and severity of water pollution. This paper presents the systematic framework of wastewater reuse potential estimation. Based on the regional disparities in China, a linear programming optimization model is developed to explore the potential wastewater reuse quantities, under physical and economic constraints. Sensitivity analysis and Robust Counterpart (RC) optimization are performed to discuss the influences of key parameters and the reuse quantity's decision making under uncertainty. Based on the model, effectiveness of different policy scenarios of water price changes are simulated and evaluated, providing information regarding China's water and wastewater management.     

Combination of Advanced Oxidation Processes and biological treatments for wastewater decontamination--a review

Nowadays there is a continuously increasing worldwide concern for development of alternative water reuse technologies, mainly focused on agriculture and industry. In this context, Advanced Oxidation Processes (AOPs) are considered a highly competitive water treatment technology for the removal of those organic pollutants not treatable by conventional techniques due to their high chemical stability and/or low biodegradability. Although chemical oxidation for complete mineralization is usually expensive, its combination with a biological treatment is widely reported to reduce operating costs. This paper reviews recent research combining AOPs (as a pre-treatment or post-treatment stage) and bioremediation technologies for the decontamination of a wide range of synthetic and real industrial wastewater. Special emphasis is also placed on recent studies and large-scale combination schemes developed in Mediterranean countries for non-biodegradable wastewater treatment and reuse. The main conclusions arrived at from the overall assessment of the literature are that more work needs to be done on degradation kinetics and reactor modeling of the combined process, and also dynamics of the initial attack on primary contaminants and intermediate species generation. Furthermore, better economic models must be developed to estimate how the cost of this combined process varies with specific industrial wastewater characteristics, the overall decontamination efficiency and the relative cost of the AOP versus biological treatment.     

Perspectives on multi-benefit water reuse systems: A confluence of water and wastewater management planning

The multiple benefits of water reuse have yet to be fully realized in our urban water management systems. One pathway to optimal implementation is to plan for their integration with wider assets in water resource or drainage and wastewater management plans. This paper explores the perspectives of water resource and wastewater management planners. Qualitative data was gathered from a workshop organized by the Chartered Institution for Water and Environmental Management (CIWEM) with 25 participants from England's Water Service Providers (WSPs), regulators (Ofwat and the Environment Agency) and consultants working within the UK water sector. The participants acknowledged that water reuse is relevant to both water resource and drainage and wastewater management planning, but that current regulatory and funding frameworks are constraining effective engagement between water resource and drainage and wastewater management planners by encouraging the development of separate plans. A general consensus of the participants was that it would be beneficial to include water reuse technology within current and future Water Resource Management Plans (WRMPs) and Drainage and Wastewater Management Plans (DWMPs). Participants suggested this could be developed through collaborative working partnerships and support from regulatory and funding frameworks that allow for the growth and development of innovative technologies and nature-based solutions. Participants also highlighted a stronger economic case could be made for water reuse technologies if the approach seeks to capture the wider benefits and not only the ‘best value’ solution. Societal acceptance and the availability of good quality data will be key to the successful adoption of any incentivized water reuse schemes.

Planning an urban wastewater system with centralised greywater reuse: a case in Beijing

This paper presents a proposed centralised greywater reuse (CGR) system for Daxing New City, Beijing. This system would use separate greywater and blackwater discharge pipes in residences and public buildings. Greywater would be treated in a centralised plant and reused for public purposes. Water supply–demand balance analysis showed that this system would conserve 28.5% of freshwater resources. A centralised wastewater reuse system that would conserve the same water resources and serve the same consumers was developed for comparison. The greywater reuse system would cost 1.2% more than the reference system, but would decrease the pollution load by 10% and improve the water-quality compliance of the Xinfeng River (total phosphorous: 24–42%, total nitrogen: 0–7%). The proposed CGR system exhibited acceptable water conservation, environmental impact, and construction and operation costs, and would thus be suitable in urbanising areas that face water shortages and aqueous environmental deterioration.

Household attitudes toward wastewater recycling in Saudi Arabia

Domestic water supply is an essential but challenging public service, especially in countries with rapid population growth and limited freshwater resources. Wastewater recycling has now become a sustainable source of domestic water supply worldwide. In Saudi Arabia, the energy-intensive desalination process meets over 60% of municipal water demand, rising by about 6% within the last two decades. The government has set an ambitious target of complete recycling of treated wastewater in major cities by 2040. Based on a questionnaire survey of 625 households, this study investigates household willingness to reuse treated greywater (TG) for non-drinking domestic applications and the factors that influence their attitudes toward wastewater recycling. The findings indicate more acceptability (agree or strongly agree) of reusing TG for laundering (males: 36.9%, females: 31.7%) than bathing (males: 11.6%, females: 12.1%). Chi-Square analyses show that residential location, age, and education significantly influence household attitudes to reuse TG, but gender and nationality do not. There is more prospect of agreeing to reuse TG for laundering than bathing across all ages groups, residential locations, nationalities, and genders. Educational attainment is the only significant predictor of the likelihood of using TG for bathing and laundering with an odds ratio of 1.26 and 1.04, respectively. Age and gender are significant predictors of the odds of reusing TG for laundering only. Behavioral change campaigns are key to scaling up wastewater recycling to reduce reliance on expensive seawater desalination and dwindling freshwater resources.     

Development of a re‐aeration equation for the simulation of dissolved oxygen in degraded streams

Discharge of domestic and industrial wastewater into the water bodies is the prime source of degradation of the freshwater ecosystem. Re‐aeration of the river allows the rejuvenation of river water quality by absorbing oxygen from the atmosphere at the air‐water interface. An accurate estimation of the re‐aeration coefficient helps to determine the assimilative capacity of streams and wastewater management also. This paper aims to develop the re‐aeration equation and its validation by modelling dissolved oxygen of the Yamuna River. Predictive re‐aeration equations are used to identify their applicability to the study area and the new equation is designed using multivariate statistical regression techniques. QUAL2Kw model is used to validate the equation by modelling dissolved oxygen. Results indicate that the developed equation performs better than the predictive re‐aeration equations for the prediction of water quality.

Developing a methodology to recover the cost of wastewater reuse: A proposal based on the polluter pays principle

In this study, we propose a cost recovery model for a wastewater treatment and reuse process based on the polluter pays principle that, among other things, provides appropriate incentives for efficient waster use and guarantees its future availability. Finally, the proposed cost recovery model is then applied using date provided by the Wastewater Treatment Plant of Santa Cruz de Tenerife (Canary Island, Spain). Using the tariff system proposed in this article for wastewater reuse, citizens would become aware of the financial investments involved in this process with the consequent impact on saving water, which would then help maintain reserves.

Successful wastewater reuse scheme and sustainable development: a case study in Adelaide

Freshwater availability to meet the growing needs of humankind has raised serious concerns in the recent past. Two immediate responses to counter this challenge are efficient allocation of the scarce resources, and development and use of alternative sources of water. While ‘water markets’ are seen as a means to achieve efficient allocation of the scare resources, treated wastewater and low‐quality water are now considered as potential sources of water to supplement the freshwater supplies. However, the latter option, that is use of reclaimed water as an alternative, imposes concerns regarding its suitability to sustain development. This is because of various issues related to wastewater usage and application. At the same time, it is also true that a successful and well‐planned reuse scheme can help achieve sustainability as evidenced in some isolated cases around the world. In line with this, the current paper adopts a case‐study approach to demonstrate how a successful reuse scheme in Adelaide, South Australia, has contributed to the sustainable development of the region. The paper looks into the socio‐economic and environmental dimensions of sustainability and arrives at a conclusion that properly planned and managed reuse schemes backed with effective regulatory and policy measures can lead to sustainable development.
