When designing an ozone water treatment system, as with any engineering project, there are tradeoffs between cost and performance.  One aspect of design for such systems involves the controls.  Depending on the application, it is entirely possible to design a system with fully manual controls that will function well.  Such systems require operator attention should […]

Spartan suggests that you consider the specialty conference Disinfection 2009 and give special consideration to submitting an abstract for a presentation.  the conference will be held at: Omni Hotel at CNN Center Atlanta, Georgia Conference: February 28 – March 3, 2009 Exhibition: February 29 – March 1, 2009 The Call for Abstracts is now available.  […]

Spartan Environmental Technologies provides ozone water treatment systems for a variety of applications.  As we have mentioned in previous posts, one of the key elements of such systems is gas preparation.  Oxygen or dried air can be used to make ozone.  In this post we are going to discuss oxygen preparation systems for ozone generation. […]

One of the things that have always intrigued us about the water industry is the number of people that regularly drink bottled water but complain about the cost of water from their local utility.  Why do people pay $1.50/gallon for bottled water, but complain about water from the tap that costs $0.02/gallon? Now we understand […]

We are continuing our discussion on ozone for odor control applications. Last time we mentioned that ozone can be applied in the gas phase by mixing ozonated gas with contaminated air or that the ozone can be applied using a wet chemical scrubber with the ozone in the liquid phase. The simplest arrangement is to […]

Most of our discussions regarding ozone have been focused on water treatment.  Ozone is also used in air treatment to reduce or eliminate odors.  Many consumers may be familiar with ozone based systems for cleaning air in the homes, but municipal and industrial applications have also benefited from the use of ozone based odor control […]

In the last posting we discussed the use of oxidation in wastewater treatment.  We noted that very high levels of organic in wastewater are likely to make oxidation technologies less economical than other techniques, especially biological.  In this post, we will discuss the types of applications where oxidation may be the preferred solution. In general […]

In In this his posting we will discuss the when oxidation might be an appropriate technique for wastewater treatment versus other techniques such as stripping, filtration, absorption or biological treatment.  The most important consideration is whether the species of concern can be oxidized.   Oxidation is mainly applied to organic compounds although certain inorganic compounds can […]
