Clearwater Industries offers free process water and wastewater testing. We perform comprehensive jar testing using a wide array of flocculants and coagulants to isolate the top-performing clarifying chemistry for any application. We then provide a private video link that allows you to see the liquid/solid separation in real-time. Our team can provide actionable information regarding chemistry dosing, settling velocity, and equipment sizing with this information.

Sample Requirements:

Preferred Method:

Two 5 gallon buckets of representative liquid slurry. If chemicals are being used, please omit current treatments for 1 hour before sample collection.

If the slurry is not available:

Two 5 gallon buckets of representative water and (1) 5-gallon bucket of representative process solids (raw feed).


Two 5 gallon buckets of process representative solids. (Clearwater will make the slurry with Milwaukee tap water)

Packaging Instructions:

  1. Divide 10 gallons of the slurry sample into (2) 5-gallon buckets.
  2. Buckets should be free of any leaks.
  3. Secure the lid of the buckets with duct tape.

Precipitation, Softening, Heavy Metal Removal

Clearwater Industries has experience with the precipitation of heavy metals.  In this process, the pH of the water is adjusted to create an environment where dissolved solids are more likely to solidify to the point they can be settled.  Once they are in this form, we can use our flocculation and sedimentation processes to remove them from the water.
