Ljungskile WTP in Sweden, was faced with unacceptably low ozone availability due to weakness in power supply and an old design in the generator systems that could not cope with power spikes.
In June 2006, Primozone delivered a completely new ozonating system consisting of oxygen generator, ozone generator and mixing system. Installation took less than one working day.
Since the Primozone GM-18 generator was installed, the plant has been constantly in operation, despite severe disturbance in the public energy supply
The Waterworks requested a second train of oxygen + ozone generator to be installed in 2008 due to the increasing content of organic material in the raw water. We installed the system in April 2008, with only 20 minutes of downtime. After two and a half years the system is still working perfectly without any breakdowns reported.
The plant manager at Ljungskile WTP, Mr Daniel Lingbrand is very satisfied and says 'Since we installed the Primozone ozone generator system we have got rid of the severe disturbances in the ozone production due to the somewhat 'dirty electricity' that we have here. Furthermore has our electricity bill been halved and at the same time we get twice the volume of ozone. We are very happy indeed with the Primozone ozone generator system'
“We are delighted that Ljungskile water chose us to supply a second generator to increase ozone dosage to combat an increase in the growth of organisms in the water. This demonstrates the reliability and cost-efficiency of our systems. They are perfect for replacing older, less efficient ozone generators”. Says Dan Johansson, Primozone’s Sales and Marketing Director.
