Does the recycling of waste streams from drinking water treatment plants worsen the quality of finished water? A case assessment in China

The overall purpose was to assess the feasibilities of recycling filter backwash water (FBWW) and combined filter backwash water (CFBWW) in a drinking water treatment plant in south China. The variations of regular water-quality indexes, metal indexes (Al, Mn and Cd), polyacrylamide and disinfection by-product indexes (trihalomethanes and their formation potentials) along with the treatment ...

Decision making and technology selection in water (reuse) applications

In recent years, a large number of developed countries have considered water reuse schemes as a mandated alternative water resource to tackle water scarcity. With increasing knowledge on and understanding of the merits of water reuse in developing communities, a number of planned water reuse schemes have also been established (Chen et al., 2012; Fatta-Kassinos et al., 2011a). The range of water ...

Improved calcium sulfate recovery from a reverse osmosis retentate using eutectic freeze crystallization

A novel low temperature crystallization process called eutectic freeze crystallization (EFC) can produce both salt(s) and ice from a reverse osmosis (RO) stream by operating at the eutectic temperature of a solution. The EFC reject stream, which is de-supersaturated with respect to the scaling component, can subsequently be recycled back to the RO process for increased water recovery. This ...

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 ...
