Environmental performance of wastewater reuse systems: impact of system boundaries and external conditions
Wastewater reclamation will be a significant part of future water management and the environmental assessment of various treatment systems to reuse wastewater has become an important research field. The secondary treatment process and sludge handling on-site are, especially, electricity demanding processes due to aeration, pumping, mixing, dewatering, etc. used for operation and are being ...

Car wash wastewater treatment and water reuse – a case study
Recent features of a car wash wastewater reclamation system and results from a full-scale car wash wastewater treatment and recycling process are reported. This upcoming technology comprises a new flocculation–column flotation process, sand filtration, and a final chlorination. A water usage and savings audit (22 weeks) showed that almost 70% reclamation was possible, and fewer ...

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 ...

Financial and economic feasibility of decentralized wastewater reuse systems in Beijing
Many decentralized wastewater reuse systems have been constructed in Beijing. However their performance is not as good as expected. The total amount of reclaimed water used in Beijing is much less than the designed capacity. In order to understand the reasons causing such poor performance, an integrated financial and economic feasibility analysis for the decentralized wastewater reuse systems in ...

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 ...

Reclaimed wastewater quality enhancement by oxygen injection during transportation
In-sewer treatments have been studied in sewer systems, but few have been carried out on reclaimed wastewater systems. A study of oxygen injection has been performed in a completely filled gravity pipe, 0.6 m in diameter and 62 km long, in cast iron with concrete inside coating, which is part of the reclaimed wastewater reuse scheme of Tenerife (Spain). A high pressure oxygen injection system was ...

Development of monitoring and evaluation system for wastewater issues in Palestine
Wastewater is the main source of groundwater pollution if it is not properly collected and treated. In many parts of the Gaza Strip and the West Bank wastewater is collected through cesspits, while in other areas it is collected through networks and treated in central treatments plants. Collecting aggregate information on the level of indicators with concern to the wastewater issues (collection, ...

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 ...

Impacts of onsite greywater reuse on wastewater systems
Together with significant water savings that onsite greywater reuse (GWR) may provide, it may also affect the performance of urban sewer systems and wastewater treatment plants (WWTPs). In order to examine these effects, an integrated stochastic simulation system for GWR in urban areas was developed. The model includes stochastic generators of domestic wastewater streams and gross solids ...

A Deeper Look into Decentralized Water Reuse
Specialized wastewater treatment & reuse systems provide sustainable infrastructure solution Water is a vital resource in the operations of many industrial processes. The increasing demands for water for agricultural, drinking and industrial processes has put significant strain on global freshwater supplies as the world’s population continues to grow. In many parts of the world, the ...

Zero liquid discharge (ZLD)
Zero liquid discharge (ZLD) is desirable to industry as well as the environment because it saves money, reduces liability and generates good will with customers and neighbors. ZLD facilities take strides to reduce the amount of water used in their manufacturing process, sometimes they use advanced wastewater treatment equipment to recycle a portion of their wastewater, and finally they use a ...

Risk assessment of treated municipal wastewater reuse in Sicily
In Italy, the restrictive approach for treated wastewater reuse in agriculture has led to some difficulties in promoting this practice. In order to assess the health risk associated with the use of wastewater in agriculture, an experiment was conducted in an open field near the constructed wetland (CW) system of San Michele di Ganzaria (Eastern Sicily), during the irrigation seasons ...
