Chemical Oxidation for Remediating Contaminants November 28, 2006

We’ve been using chemical oxidation for years on certain contaminants. Chemicals such as hydrogen peroxide, calcium peroxide … combinations of all sorts of things can work if the selection of chemicals is appropriate to the situation.

Hydrogen peroxide and Fenton’s Reagent can degrade certain contaminants but have a long-term negative effect on soil, rendering it impossible to polish up with microbes. We get asked frequently to finish a site previously treated with hydrogen peroxide, but, unfortunately, once the soil is ruined, it’s a hopeless cause.

We offer a unique oxidizer that completely dissipates in 40 hours, and we follow that up with a treatment utilizing our microbes. It is very effective. Call for a price quote.

Many companies utilize calcium peroxide as an oxygen source. It is a slow-release product that is advertised as “passive.” It is expensive, and it can work; it also cannot work. The big objection to it is that it creates a very high pH, around 12, which kills most bacteria, both indigenous and augmented. It is also very slow. And expensive.

We can discuss options for you.

Bioaugmentation vs. Biostimulation November 14, 2006

You may have heard these terms bandied around some, especially if you have a contaminated site and are thinking of bioremediation as a cheap and effective clean-up method.

Simply put, bioaugmentation means adding microbes that are grown off site, then added to the site. The nice thing about this approach is that you (we) can determine which microbial blends to use. For example, for petroleum spills, we like to use petroleum-degrading microbes; for manure lagoons, we use manure-degrading bacteria. Pretty simple!

Biostimulation utilizes existing bacteria (microbes) on the site, “indigenous bacteria,” if you will, and stimulating them with nutrients: the cheapest being cow manure, the best being our Biobooster. (It really is the best; in fact some customers that are stuck with another manufacturer’s product will use it to up the microbial plate count!)

 

Our system is to use both technologies. We like to add the known degrading bacteria, site specific, and at the same time, stimulate the existing bacteria; thus, generating enormous plate counts.

We can just offer to you our Biobooster if you — or the regulators — prefer biostimulation. Before you decide on that, though, you — or we — should determine if you have the proper indigenous microbes. That process takes about two weeks, and we will give you not only the total plate count but the percentage of the good degrading bacteria. There is a fee for that service, and you can call anytime to discuss.

Plate Count Results, November 2006 November 7, 2006

When you purchase our products, we give you detailed mixing instructions in writing, or you can call us anytime. A California regulator recently was wondering how we came up with our protocol, implying that we just made it up!

It took several years, and we are constantly refining the process. We would add different quantities of our dry Biocritters (bioremediation microbes) with different quantities of our “world’s best” nutrient, our Biobooster, and measured plate counts with different mixtures, and different time periods. We then select the best combination which yields the highest plate counts, and pass this on to you.

One of our clients had his mixing tank analyzed for plate counts using his lab. The result was TNTC, which means “too numerous to count”! We’re not surprised as we observe this all of the time, but we thought you would like to know! If you would like to see a copy of this report, send an e-mail and we’ll e-mail it back to you.
