9 Reasons to Use Cad-Con 1000™ When Blocking With Alloy

Written by James Williamson, CEP, CHMM


1. You want a total solution for alloy tank wastewater.  Cad-Con 1000™ provides reliable treatment of tank wastewater contaminated with blocking alloy metals.

2. Effective treatment for the water component is a must. The liquid portion (water) must be suitable for discharge to your local sewage treatment plant. Used properly, cadmium and lead are typically reduced well below your local sewer discharge limits.

3. Effective treatment for the hazardous waste component is also a must. In an extreme case study, Cad-Con 1000™ reduced alloy tank water with 280 mg/L cadmium and 250 mg/L lead to a TCLP of essentially zero (below .002 mg/L). The threshold limits for hazardous waste are 1 mg/L cadmium and 5 mg/L lead.

4. You need something that works consistently each time it is used. Because Cad-Con 1000™ is used as a batch treatment of your waste, it is always full strength, never loses potency and its effectiveness is never diminished over time.

5. You need a product that’s easy to use. Cad-Con 1000™ is easy to use and simple to incorporate into your existing process. Anyone can do it; just follow these instructions:

  1. Drain your alloy reclaim tank into a suitable container, such as a 5-gallon bucket
  2. Treat – mix in Cad-Con 1000™ and stir every 10 minutes to keep blended for half an hour
  3. Clarify – filter or let solids settle to the bottom to form a sediment layer
  4. Dispose – pour off clear water to drain, place sediment in trash

6. You don’t need any additional problems. You won’t get any when you use Cad-Con 1000™

  • It’s non-hazardous
  • There are no residual hazardous wastes to deal with
  • No noxious odors or gases
  • No foaming
  • Works with your Panhandler treatment unit or other equipment

7. You want to keep your compliance costs to a minimum.  Cad-Con 1000™ is inexpensive. For the typical 5-gallon alloy reclaim tank, Cad-Con 1000™ can provide absolute compliance protection for less than $5 per week.

8. You don’t want to risk an EPA violation. Improper disposal of alloy tank water is the optical lab’s most serious environmental risk and state and federal enforcement agencies are increasingly pursuing violators with personal and even possible criminal liability.

9. If you’ve read this far, you obviously have a need. What are you waiting for? Order Here

About James Williamson: Mr. Williamson has been an Environmental Health and Safety (EHS) manager and consultant for over 40 years. In the 1990’s when doing work for several regional optical laboratories, he identified used alloy tank water as the single greatest environmental and health risk facing the industry. In response, he developed Cad-Con 1000™ as an economical alternative to expensive water treatment equipment and processes or disposal as hazardous waste. Cad-Con 1000™ has been used by hundreds of optical laboratories with confidence and reliability for over 20 years.
