Alert : Cracks Found in Chlorine Cylinder and Valves

Arlington, VA -- The Chlorine Institute has prepared recommendations for chlorine-users to inspect chlorine cylinder and ton container valves for cracks. Your chlorine supplier and valve manufacturers have also increased their inspection procedures and an extra check by end users can only enhance safety.

Although they are not common, there have been reports of both cylinder and ton container valves being found with cracks in the area by the threads for the packing nut. There are two reported incidents in the U.S. and Canada where an actual leak of chlorine is known to have occurred. Fortunately, most have been discovered before any leaks happened. It appears that the valves will not leak until they are opened since the valve will be sealed at the stem.

Both cylinder and ton container valves have been reported with cracks. The valve manufacturer and the Chlorine Institute are working to resolve this problem.

Chlorine suppliers and valve manufacturers have agreed to increase their inspection procedures and an extra check by end users can only enhance safety. CI has alerted our members as well as posted an alert on our public Web site.

The Chlorine Institute web site also includes specific information on additional safety procedures to be taken by chlorine consumers in water/wastewater facilities. Click here to download:

Norwich, NY -- Because environmental degradation of materials costs industry billions of dollars every year, design engineers are often faced with critical decisions to prevent degradation and extend the life of products and structures. This new handbook from William Andrew Publishing will help you measure, analyze, remediate, and prevent degradation.

Handbook of Environmental Degradation of Materials
Edited by Myer Kutz, ©2005

A product design engineer may have to work with several types of materials, and may have to consult numerous information sources. This handbook, with its voluminous references, directs readers to useful print and online sources.

Experts from around the world show how a diverse set of industries cope with the degradation of a broad range of materials -including metals, polymers, reinforced concrete, clothing, and wood - under adverse environmental conditions.

By implementing the advice within each chapter, companies of all sizes can improve the performance of parts and structures and realize savings.

Mr. Ceylan wants to treat leachate with RO:

I need to help for leachate treatment from garbage. Is it possible to treat leachate by sand filter + RO. Capacity is 50m3/day and COD is 14-15.000 ppm.  (Click here to post a reply)

Mr. Raber has a problem with pH dropping:

We have 3 aeration tanks in an extended aeration system.  One tank has pH fallen from 7.1 to 6.4 in several days and clarifier has become cloudy.  No change in influent pH and no change in other 2 units.

Any ideas what could cause this?
