We are frequently approached by customers looking to treat complex water problems. Ozone water treatment systems can solve many water quality problems simultaneously, so it is often considered for these situations. In many cases, however, some additional water treatment technology needs to be added to the ozone system in order to provide a complete solution.
Spartan works with a number of partner companies to provide complete water treatment packages which include ozone as an integral component. The two technologies that are often added are some form of filtration and UV.
While ozone acts as a micro flocculent, essentially a filtration aid, particulates formed need to be filtered out of the water. This means that after ozonation there will need to be some form of filtration. Normally, ozone is added to enhance filtration in these situations while simultaneously providing disinfection.
Another application where filtration needs to be combined with ozonation is where the primary application for ozone is disinfection and the water contains significant amounts suspended solids. Suspended solid can provide places for micro organisms to grow and shield them from the ozone. It is important to reduce the turbidity of the water to minimize this problem.
The exact method of filtration will depend on the nature of the water treatment application and can range from simple bag filters to reverse osmosis. Spartan works with filtration experts that not only match the proper filtration method to the application, but also ensures that the ozone will not damage the filter elements.
The other technology employed with ozone is UV. UV in combination with ozone creates an advanced oxidation process (AOP). AOP is one where there is the formation of hydroxyl radicals, a chemical compound that is a very powerful oxidant. Thus AOP form an oxidant that is more powerful than ozone alone. While hydroxyl radicals can be formed by a variety of advanced oxidation processes, e.g. ozone with hydrogen peroxide, UV ozone is attractive since it can be formed without the need to purchase or store any chemical compounds. The UV light and ozone can be created on site from electricity and air. This makes for a simple and safe process.
AOP, such as UV ozone, can be used for a variety of applications such as the removal of difficult to treat organic compounds from water. As a result this process finds application in ground water remediation and industrial wastewater treatment.
Spartan Environmental Technologies provides complete ozone water treatment solutions that can integrate filtration and UV.
