Find data by effluent characteristics

How to use this feature

You have chosen to find clean air technology data according to the characteristics of your effluent stream.  Read this section to find out:

• What information the database will need from you
• What information the database will supply in return
• How you can use the information
• What else you will need to know to select a control technology

To begin using the database immediately, you can skip to the input section.

What information will the database need?

To help the CATD match the information in the database to your control technology needs, you will be asked to characterize your waste stream according to four basic parameters:

• Total flow rate of the waste stream
• Concentration of VOCs
• Variability of the flow
• Temperature of the waste stream coming out of your process

You will not need to know exact numerical values for your process.  Each parameter is characterized simply as "HIGH" or "LOW".  In each case, you will be given a guideline range to help you make your initial choice.  The purpose is not to find an exact match for your conditions, but to help you to place your process in a general range.  (If your case is borderline, you may want to look at both possibilities.) 

What information will the database supply?

When you have supplied this information, the CATD will give you a Control Options page, which will help you select among the control technologies relevant to your waste stream.   Selecting one of the control options will give you

• a Fact Sheet on the technology you have selected
• a List of Products and Suppliers for that technology

How can I use this information?

The Control Options pages will help you select control technologies that are appropriate for your waste stream.

The Fact Sheets will give you basic information on each technology, together with links and references to more complete information.

The List of Products and Suppliers will help you contact manufacturers and installers for detailed technical specifications and prices.  A broadcast e-mail feature will allow you to contact a range of suppliers conveniently if you want to request the same information from all of them.

The CATD will also help you explore the consequences of possible process changes which could make the job that your control system needs to do easier, and could bring down the cost of the system.  For instance, if your process is rated "HIGH" on any of the four variables, you can put some resources into process improvements that would change your waste stream's flow, concentration, variability, or temperature by throttling it back, diluting it (or keeping it more concentrated), smoothing it out, or cooling it down, respectively.  The CATD will help you evaluate how each of these changes would affect your control requirements.

What else will I need to know to select a control technology?

The CATD will help you decide what kinds of control technology are likely to be appropriate for your process.  The best choice will depend on many engineering factors specific to your process, your facility, and your location. 

Besides the four input parameters, other important factors to keep in mind are:

• Composition of the waste stream.  Some materials will interfere with some types of treatment technology.
• Recovery options.  Do you want to recover material from the waste stream?

You will not need to supply input on these other factors up front.  The CATD will suggest how to take these factors into consideration when you read the Control Options pages, and the Fact Sheets for the individual technologies.

Input data

Please use the following pull-down menus to characterize your waste stream as "HIGH" or "LOW" according to the four parameters next to each menu.   As a rough guide, some dividing lines are suggested.  When you have finished your selections, click on "Submit" to get the Control Options page relevant to your case.  See above for more instructions.
