The Ultimate DAF System Buyer’s Guide: Conclusion

At face value DAF systems are pretty much like any other piece of industrial equipment – they’re an investment that you only want to make once. And in the same vane, some designs are simply better than others. With this guide, hopefully you’ve learned which design elements separate one DAF unit from another.

In summary, let’s recap the things you should discuss with a DAF manufacturer before setting a purchase in motion:

  1. What type of DAF pump is used? Why?
  2. What materials are used in DAF tank construction?
  3. What mechanical measures are taken to thicken sludge?
  4. How is dissolved air distributed into the DAF tank?
  5. What is the operating procedure for the system?
  6. What specific design considerations were weighed for your application?

The DAF system manufacturer should be able to address each of these questions with great detail and explain why they design their systems the way they do. If they can’t articulate why they do things one way and not another, then there’s a lack of attention in their engineering approach. Conversely, the manufacturer that can discuss each of these topics is better equipped to become a useful resource and partner in your project as it moves forward.

If you’re satisfied with the reasons behind the manufacturer’s design decisions, then the next step is to take a look at their project history. If they’ve only got a few projects under their belt, their understanding of DAF design may still be largely theoretical or academic. When it comes to large capital expenditures, you don’t want theoretical solutions, you want something that’s guaranteed to work.

So, whether you’re an engineer or an end-user, remember that you only want to select a DAF system once. Make sure you get it right.
