Moderate size PCB contractor and aerospace contractor
"If you're buying a cleaner from us, why not buy a closed-loop wastewater recycling system from us at the same time?" discussion: One cleaner vendor supplied a complete cleaner and separate closed-loop WASTEWATER recycling system to each of two different customers in California. After the systems were installed, neither customers could get the systems to function as a closed-loop process. The ...

Cost comparison of seawater for toilet flushing and wastewater recycling
As freshwater resources are becoming increasingly scarce, unconventional sources of water should be given new consideration. In coastal cities, seawater, with minimal treatment, can be used for toilet flushing, reducing the demand for freshwater. Currently, it is practised on a large scale only in Hong Kong. This study estimates the cost of seawater flushing and compares it to the cost of ...

Drivers for and against municipal wastewater recycling: a review
The reclamation, treatment and reuse of municipal wastewater can provide important environmental benefits. In this paper, 25 studies on this topic were reviewed and it was found that there are many (>150) different drivers acting for and against wastewater recycling. To deal with the challenge of comparing studies which entailed different research designs, a framework was developed which ...

Wastewater Recycling Project
Durban is part of the eThekweni Municipality, located on the east coast of South Africa. The combination of limited water resources in the city along with sewage capacity constraints, led to the investigation of different wastewater recycling processes since the region produces approximately 450million litres of wastewater per day. The project was South Africa’s first private wastewater ...

A review of literature on the factors affecting wastewater treatment and recycling across a broad spectrum of economic stages of development
Wastewater recycling has emerged as a prominent option among the various alternative sources of water in both developing and developed countries. However, the questions that need to be answered in this context are: how do communities determine which option is best for them, and what are the factors that make one water alternative more appealing than another? The aim in this paper is to ...

Centre for Science and Environment (CSE) Promotes DEWATS in India
Decentralized Wastewater Treatment Systems (DEWATS) are getting a boost in India through the work of the Centre for Science and Environment (CSE). CSE is a public interest research and advocacy organization located in New Delhi. Their work in mainstreaming decentralized wastewater recycling and reuse is being accomplished through research, policy advocacy and training. Their training program, ...

QUA’s Q-SEP Modules Successfully Fit Requirements at Mumbai International Airport
Overview As a part of a massive expansion plan for Chhatrapati Shivaji International Airport located in Mumbai, India, a wastewater recycle project was contracted in 2011 to cater to the growing requirements of the expanded airport. Due to increasingly strict environmental regulations, the treatment of raw sewage wastewater is required before it is allowed to flow into the natural ecological ...

The value of fracking wastewater treatment and recycling technologies in North Dakota
The oil boom in North Dakota is aided by hydraulic fracturing, often referred to as fracking. Fracking uses a pressurized water, sand, and chemical mixture to break through layers of rock and release oil and gas. This procedure produces hundreds of truckloads of wastewater for each fracked well. In this study, we analyze the financial feasibility of a system of wastewater recycling and reuse to ...

How Namibia Embraced Potable Water Reuse
The small southern African nation has been pioneering wastewater recycling since the 1960s The southern African country of Namibia, known for its wide, expansive desert landscapes, is an arid country prone to drought. Water scarcity is a harsh reality for many of its citizens, including the more than 400,000 residents of the capital city, Windhoek, which is also the hub of Namibia’s ...

Treatment for woolscouring effluent through bioacidification by acidithiobacillus thiooxidans
In this study, a promising process called bioacidification was used to remove organic pollutant from Woolscouring Effluent (WSE) by emulsion destabilisation. Chemostat experiments of bioacidification treatment inoculated with Acidithiobacillus thiooxidans were operated at high wastewater recycle ratios to achieve shorter Hydraulic Retention Time (HRT). Results exhibited high COD removal ...

Recycled Water Quality
Matching recycled water quality to beneficial uses requires an understanding of health and environmental requirements. Measures to achieve appropriate recycled water quality are determined firstly by treatment. The degree of treatment depends in part on the source and the hydraulic and biochemical characters of the wastewater. Overall recycled water outcomes may also be controlled ...

Arizona Removing Obstacles to Wastewater Recycling
Starting in 2018, new rules will allow direct potable reuse of wastewater Existing technology can efficiently treat water to any desired level of purity, but no municipal water system in the United States has yet adopted direct potable reuse, or the use of recycled sewage for drinking water, mostly because popular psychological and political barriers have been difficult to overcome. Even in ...

Clean production in stone cutting industries
The stone cutting industry uses high volume of water for cooling purposes and produces large volume of sludge. The disposal of both the wastewater and the sludge to a solid waste disposal site is costly and environmentally unacceptable. Wastewater and sludge from stone cutting industries in Jordan has been characterised and reused in various processes. Stone cutting industries can be modified to ...

Beer Breaks Barriers in Public Perception of Wastewater Recycling
Medium-scale wastewater reuse is a perfect fit for beverage bottlers, but can beer break the ice with the public? Why would a craft beer brewery emphasize that it’s made of recycled wastewater? It might seem counterintuitive, but many hope the strategy is effective at opening people up to the idea of drinking purified recycled wastewater — so much so that local governments and ...

Overcoming the Global Water Crisis: A Focus on Wastewater Recycling & Reuse
While it is true that more than half of our planet’s surface is covered in water, a vast majority of it is saline. Fresh water, the water we use in hundreds of ways every day, constitutes only 2.5 % of all the water on the Earth. Today, the world faces what is known as the water crisis. Parts of the world do not have access to this most vital resource on the planet. Therefore, a focus on ...

Fighting the water crisis with wastewater recycling
Whether it’s sewage, domestic greywater or industrial run-off, wastewater recycling can play a critical role in averting the water crisis. Water scarcity is a significant climate change risk, but several other factors converge to make it a bigger problem than people realise. Add localised population growth, increased urbanisation, and water mismanagement, and you have a ...

Ideal treatment of laundry wastewater with ultrafiltration installations
Treatment of very dirty work clothing also produces heavily polluted, oily/greasy wastewater. It is the aim of laundry wastewater treatment to reduce fresh water consumption and to minimise the volume of residuals. At the same time, adherence to the limit values according to appendix 55 of the General provisions on hydrocarbon, heavy metal and AOX contamination in wastewater must be guaranteed. ...
