Struvite Sample Testing Example

Struvite Removal offers free Struvite Sample Testing to show our product is effective and to what extent. 

We do the lab tests, take pictures and offer our best recommendations for application thereafter.

No Struvite Sample is exactly alike, and each reacts with our products differently, we help get an idea of rate, and to the extent the product will work but determining the ratio of Struvite broken down as well as the pH of the solution.

For our test, we will fill a beaker with 100% solution, if necessary can check other solutions, place the struvite samples in the beaker as well as a magnetic stir bar to resemble a recirculation. Every 30 minutes check the weight of the dried sample and the pH of the solution. Once dissolved, we test to find the spent solution by adding more and more sample until it's spent. This helps to find a pH the client should look for to make sure the product is done working, and find ratios to get an idea of how much Struvite it can break down.

This test shows the full extent of the sample being broken down in our product, however in many applications the product needs to break up the 1:1:1 ratio of MAP to break down the solids, and the structure falls apart like a house of cards, the solids can then be caught with less product being needed.

An example of the test we offer free:

50mL of 100% Solution Struvite Remover

Struvite Initial Sample Weight: 3.81grams

Set up as a recirculation using a magnetic stirrer and placing the Struvite on the opposite side to better agitate the struvite.

Weight of Struvite (grams)
pH of Product
30 minutes
Dissolved/In Solution

Continued test to see amount dissolved in product

Weight of Struvite (grams)
pH of Product

Added 7.75 grams, totaling  11.56 grams

1.5 hours
2.8 grams remaining
2 hours
1.66 grams remaining
2.5 hours
1.34 grams remaining

Added 2.84 grams, totaling 14.4 grams

2.1 grams remaining
12.3 grams dissolved/In Solution

From this test can see the Struvite was easily broken down in a very weak recirculation.

The total amount of Struvite that was dissolved/broken down was 12.3 grams with two pieces adding up to 2.1 grams remaining the next day. This results in our product being effective to a pH of 4 on your struvite and approximately 50 grams of our product to dissolve and break down 12.3 grams. About 4 parts product to 1 part of your Struvite.

The pictures below are from the same test, can see the initial struvite sample and solution, second picture is of the test taking place, and lastly the end result of the sample completely broken down.

We will accept any samples of scale and do this testing free of charge, and share all results and our thoughts.
