Identification of bacteria assimilating formaldehyde in a biological activated carbon filter by means of DNA stable isotope probing and next-generation sequencing
Ozonation followed by a biological activated carbon (BAC) filter is a common process of advanced water purification. Ozone can generate formaldehyde (FA) as a harmful by-product, while the subsequent BAC filter is efficient at removing FA. FA adsorption is limited on activated carbon because of its hydrophilic property and low molecular weight. Thus, biological degradation by biofilms ...

Case Study - Water Resuse/Recycle
A leading electronics company faced increasing water costs of both influent and effluent. They contracted Applied Water Solutions for a pilot study using some of the most advanced methods of water purification on effluent from a clean out of place (COP) system. The pilot provided proof of principle of the selected process to recycle some of the DI Water rinse, and justified a ROI of less than one ...

Advanced technology for water purification by heterogeneous photocatalysis
The TiO2 photocatalytic degradation of 2,4-dichlorophenol (2,4-DCP) and pentachlorophenol (PCP) was examined using a prototype photoreactor fabricated by Nulite. The degradation of both pollutants proved very efficient as in 12 min it was possible to bring the concentration of 2,4-DCP from 10 to 0.5 p.p.m. and in a separate experiment the concentration of PCP from 100 to 0.5 p.p.b. The effect of ...

Pesticide removal through wastewater and advanced treatment: full-scale sampling and bench-scale testing
Dieldrin and DDx removal through wastewater treatment, ozonation, and microfiltration was assessed for a water reuse project for groundwater replenishment in Monterey, California, USA. Full-scale sampling was conducted at the wastewater treatment plant, and physical wastewater treatment processes, ozonation, and microfiltration were tested at the bench scale. Removals observed through ...

Pathogen Removal and High Log Reduction Value Crediting for Reverse Osmosis Systems Using Continuous Strontium Monitoring
Public potable water supplies are being stressed by growing population, cyclical droughts, and climate change. One way to sustainably augment the potable water supply is to recycle (reuse) wastewater. This is performed by using a tertiary wastewater treatment facility followed by advanced water purification (AWP) which includes; Reverse Osmosis (RO), UV/advanced oxidation and free chlorine ...

R&D areas for next-generation desalination and water purification technologies
By 2020, desalination and water purification technologies are expected to contribute significantly to ensure a safe, sustainable, affordable and adequate water supply in India. The cost of producing water from the current-generation desalination technologies has declined over time at a rate of only approximately 4% per year. Hence the need to accelerate our Research and Development (R&D) ...

Study on failure rate analysis for water distribution pipelines
Many of the waterworks facilities in Japan were constructed during the rapid economic growth period. Today, the deterioration and renovation of these aged facilities have become a pressing issue. There are approximately 600,000 km worth of water pipelines laid out across Japan, accounting for about 70% of the nation's water-related assets (totalling ¥40 trillion). To provide water that is safe to ...

Falling Oil Price Forces Operators to Find Cost Savings in Water Management
When oil prices were 80 to 100 dollars per barrel, water management costs were high, but they were tolerable when money was flowing profitably. However, as today’s falling price nears 40 dollars, water related costs are still high and only exacerbate widespread industry losses. The 150 US-based companies tracked by Oil & Gas Journal and Oil & Gas Financial Journal reported that ...

Can saltwater quench our growing thirst?
An increasingly water-stressed world takes a new look at desalination. It seems simple enough: Take the salt out of water so it’s drinkable. But it’s far more complex than it appears at first glance. It’s also increasingly crucial in a world where freshwater resources are progressively strained by population growth, development, droughts, climate change and more. That’s ...
