Economical calculations for the use of Ozone in Cooling Towers
Abstract Ozone has been successfully applied to industrial cooling water systems with the resultant improvement in operational efficiency due to increased heat transfer, reduced system corrosion, improved environmental impact and reduced on-going chemical expenditure. The aim of this paper is to provide practical advice on the options available for the application of ozone and the potential ...

Case histories of using tin technology to control corrosion in water systems
Stannous chloride is an alternative corrosion control in aqueous systems. Stannous chloride’s effectiveness as a better corrosion inhibitor has been demonstrated in both municipal drinking water and industrial cooling water applications and its use has a reduced impact on rivers and streams. Orthophosphate and other phosphate compounds are the most common treatments for reducing corrosion ...

A dynamic ventilation model for gravity sewer networks
To implement any effective odour and corrosion control technology in the sewer network, it is imperative that the airflow through gravity sewer airspaces be quantified. This paper presents a full dynamic airflow model for gravity sewer systems. The model, which is developed using the finite element method, is a compressible air transport model. The model has been applied to the North Head ...

Pearl river valley water supply district case study
Performance History and Discussion In-Pipe Technology implemented the first phase of a collection system Professional Services Program in 2001. Beginning in 2002, additional collection system basins were added to the services program. Currently, the treated areas include the North and South shore of the Pelahatchie Bay, the Main Harbor, and two Lagoon Waste Water Treatment Plant (WWTP) collection ...

Corrosion Coupons Vs. Onguard: Which is Right for You?
Which Purafil monitoring solution is the best for your facilities? The short answer is, it depends. While both OnGuard Devices and Corrosion Coupons utilize copper and silver metal to measure the corrosivity of the surrounding air, there are a number of factors that will determine which one your facilities will benefit most from. It is also important to note that corrosion occurs faster at higher ...

Application of Ozone in Cooling Water Systems
The first comprehensive study - bench-top laboratory investigations, pilot scale testing, and critical monitoring and evaluation of field applications - addressing the effects of ozone as a stand-alone cooling water treatment program is presented. The study also represents the first critical comparison of ozone-treated systems with non-treated systems. Excellent corrosion control can be attained ...
