Storm tank cleaning systems

Storm Blaster heavy duty tank cleanerStorm tanks will fill with excess water from the sewage system in the event of heavy rain. This is to prevent sewage from over loading treatment plants. The contaminated water stored in such tanks is then release back into the sewage system when it can better cope. In this way the water treatment systems of cities are not overwhelmed and literally over flowing every time we have rain.

The water stored in such tanks contains a large number of biological and non biological contaminants. As the water in such tanks may be stored for several days considerable sediment will be left behind. Due to the presence of biologically active contaminants there is a potential for foul smelling and toxic residues to form due to bacterial action. Not only so these residues represent health and safety / pollution concerns if left uncleaned they will eventually impede the effective operation of the storm tank. 

Impingement cleaning

Traditionally storm tanks are cleaned by eductor systems that create a swirl as the tank empties. This attempts to dislodge residue and debris. In many cases, however, the cleaning by such systems is not sufficient particularly if a thorough clean removing all foul smelling residue is required. The HydroWhirl Orbitor Storm Blaster impingement cleaning system is an alternative method that ensures the removal of even very tough residues.

The Orbitor Tank cleaner in action

The video below shows a recent installation of the Orbitor Storm Blaster above a Victorian storm tank. The powerful impingement cleaning jet cuts off just below the horizontal line thus protecting the infrastructure around it. Over time the jets cover each inch of the tank below removing all debris and residue.
