Evaluation of treatment and disinfection of water using cold atmospheric plasma
In this paper, the disinfection of water is investigated using plasma spark treatment and the results are compared with conventional techniques. Inactivation of the Enterococcus faecalis and Escherichia coli bacteria is considered in the treatment process of water by the plasma spark. For this purpose, many physical and chemical parameters of water are measured and the obtained results ...

Control of trichloramine formation by two-step chlorination in water purification processes
Chlorinous odour in drinking water is of great concern in Japan. Some water utilities use trichloramine (NCl3) as an index of chlorinous odour and are attempting to control its levels in drinking water. In the present study, the effects of two-step chlorination, involving addition of chlorine twice, on NCl3 control were investigated. The results regarding ammonia (NH3), glycine solutions and ...

Full Scale advanced oxidation process for TOC removal and cost reduction by reclaiming water
For many commercial and industrial operations, looking at ways to reduce water and wastewater monthly bill costs, water reclaim is essential. A major water treatment challenge encountered in the search for new water sources is the reduction of total organic carbon (TOC) and Chemical Oxygen Demand (COD) at one or more locations. Properly designed advanced oxidation processes have demonstrated ...

4 Benefits of Electrocoagulation for Groundwater Treatment
Even though groundwater sources are somewhat safer from pollution and contamination due to their underground location, they are still susceptible. A factory may not be able to discharge wastes directly into a groundwater source like they can a surface water stream or river. However, there are many other ways that waste could potentially contaminate a groundwater source. Because soil is ...

In Search of Ideal Groundwater Treatment
As surface water supplies become increasingly polluted and difficult to treat, the use of groundwater continues to increase. Every day, more than 77 billion gal of water are withdrawn from aquifers for a variety of uses including human consumption. Worldwide, groundwater makes up 95% of available freshwater, and nearly half of the U.S. population receives all or part of its drinking water from ...

What’s That Smell? Wastewater Edition
Sewage is not known for its pleasant aroma, but what exactly is that smell, and what causes it? The municipal wastewater treatment process can release odors in the collection and treatment process. Wastewater is mostly water, but it also contains organic and inorganic matter, bacteria, and other microorganisms. These all contribute to processes that release gases into the air that are unpleasant ...

Protect Waterworks From Flooding with Wastop Access Case Study
Problem: Rising sea levels and extreme weather conditions are becoming increasingly common. Wherever we live on the earth, climate change affects us all. One issue that has therefore become increasingly relevant and important in recent years is to protect people and communities from flooding in waste water and surface water systems – which can have disastrous consequences. One ...

Iowa pork processing plant eliminates waste water treatment odor and reduces odor control costs
The Problem - Increasing encroachment by new neighbors began causing problems for an Iowa pork processing facility. Though the plant had been there for more than 20 years, new neighbors complained about odors stemming from the waste treatment and composting operations at the plant. The "loud" and frequent complaints of the neighbors brought tremendous regulatory pressure down on the facility. ...

Monitoring of odors emissions from a large wastewater treatment plant
Abstract Because of complaints related to odors emissions from the large “Seine Aval” wastewater treatment plant (2 000 000 cubic meters/day) located near Paris, an extensive measurement programme has been performed, both by olfactometric and physicochemical techniques, in order to characterize the emissions from each step of the water- and sludge treatment processes, and their ...

Odorant screening and possible origin analysis of odor episodes in one reservoir in northern China
Odorous drinking water problem occurred repeatedly in one city in northern China in recent years. The uniqueness of this odor episode lay in two aspects: (1) the odorous chemicals were quite different from common odorants, such as geosmin and 2-MIB; and (2) it occurred repeatedly in different seasons during a time span of more than 2 years. The screening of odorants was the first and one of ...

South Australia - Great Leap Forward in Water Treatment
Residents in the Adelaide Hills are receiving clean and filtered water from a $7.5 million water treatment plant using worldfirst technology and reducing the need for chlorine disinfection. The plant at Mt Pleasant has seen SA Water roll out its MIEX (magnetic ion exchange) resin technology, which reduces the level of dissolved organic carbon (DOC) in drinking water, the main cause of colour, ...

Noses for Surveillance of Wastewater from Secondary Treatment Plants in Alexandria, Egypt
Intermittent discharges of industrial chemical pollutants into sewers can have a damaging effect on the processes involved in treating wastewater. They are sometimes able to pass through treatment plants and enter into the receiving water, to exert a harmful effect on the environment and possibly pass down a river to the intakes forwater supplies. We evaluated the use of an electronic nose ...
