FREQUENTLY ASKED QUESTIONS
The Clearflow Gel Block Flocculant removes soil particles such as clay, sand and silt, as well as the contaminants that may be attached to the particles such as nitrogen and phosphorus nutrients, metals and hydrocarbons.
Yes, results have shown reductions in dissolved metals in many applications through the removal of colloidal TDS (Total Dissolved Solids); however, these results vary depending on water chemistry and the metals present.

No, Clearflow products are non-toxic and environmentally safe, according to studies completed by two major universities. The molecules are too large to bioaccumulate and, unlike cationic polymers, will not suffocate fish or other aquatic organisms.
Environment Canada-certified toxicity tests on fish (fathead minnow, rainbow trout), water fleas and algae have been conducted on the water treatment product(s) offered by Clearflow.
No, the Clearflow Gel flocculants are designed to release directly into turbulent flow. If water is stagnant, the Gel Flocculant blocks will swell but not release. When the water flow increases (for example, due to spring runoff or manual pumping) the hydrated block will slowly dissolve and self-dose to a safe, effective level in the water.
Soil Lynx, when applied, binds to the soil and/or natural material, such as jute.
Validation of our toxicity statements and environmental impact studies have been conducted by the University of Alberta and the University of Guelph and third-party laboratories.
What happens to the particles bound by Clearflow products?
The polymer will hold the sediments and contaminants until the polyacrylamide degrades. The anionic polyacrylamide degrades at a slow pace, releasing the sediments and contaminants at much lower, safer levels for the environment.
Alternatively, the flocculated material can be manually removed, either by removing the jute fabric or other material it was bound to, or by manual removal of the flocculated sediment itself. The client may wish to remove the flocculated sediment if it is known to contain high levels of contaminant, or for maintenance needs.
My project has a problem with hydrocarbons. Can Clearflow products remove them?
Small amounts of hydrocarbons attached to the soil particles can be removed from the water.
We can also treat higher amounts of hydrocarbons using different pre-treatment techniques.
We have found that typical products used for erosion control and flocculation are not consistent in the North American marketplace. The efficacy of the products can be affected by such site-specific properties as soil lithology and water chemistry. If the product is not having the desired effect, other companies commonly resort to adding more of the same product.
Our products are designed to be site-specific and environmentally friendly. Our company will match your soil or water sample to the most effective polymer product(s), ensuring that the product used is the best match for your site soil and water chemistry. This will not only bring peace of mind that the product will indeed work effectively on your site, but also reduces the total amount of product needed to be purchased by the client.
