    [post_content] => Many of us know what happens when you mistakenly under-preserve a biological product: the bottles start to bulge or suck-in (the latter can also be caused by fragrance issues), fungal growth starts to appear or it starts to have an unpleasant odor. But do you know what signs to look for if your product is over-preserved?

There is usually one noticeable sign of an over-preserved product: the customers who were consistently using your product haven’t placed an order in a while.

Understanding Preservatives

The preservation system in your biological product is a double-edged sword. If you under-preserve, you get the problems mentioned above. But if you over-preserve, your product won’t work, or it will have a significant delayed reaction. This can lead some of your repeat customers to think that the product no longer works. Over-preservation occurs when too high of a concentration of preservatives is present in a product. The preservatives are meant to be diluted to a predetermined point as indicated by the number in front of the X on the label (i.e. a 10X product would be 1 part product, 9 parts water). Diluting to the proper point allows the product to activate and begin working. If over-preserved, the product isn’t diluted enough to allow activation.

Effects on Application

The below graph (Figure 1) shows an example of an over-preserved product. As you can see, the properly preserved product began to grow 16 hours sooner than the over-preserved product. Depending on the application and holding time, a delayed start like that of the over-preserved product can kill your treatment success. Grease traps, multi-story drain treatments and septic piping are a few examples of systems that have narrow activation windows where over-preservation can limit your repeat business. At MDG, we’re dedicated to honoring the brand and reputation of our partners. Proven success is our measure of a job well done and is our promise. As one of our partners, we’ll show you how to properly dilute products so that you can avoid getting over- or under- preserved products. If you suspect issues with your current supplier, reach out to us and we’ll see what we can do to help. If you’d like to learn more about our products and support services, send us a message and one of our representatives will reach out to you. [caption id="attachment_5827" align="alignnone" width="300"] Figure 1 – This graph illustrates how an over-preserved product can have a negative impact on product application. If over-preserved, the product may have a delayed response as seen here or not work at all, having a negative impact on treatment.[/caption] [post_title] => Are you over-preserving?

Are you over-preserving?

  • MDG
  • June 24, 2020
Many of us know what happens when you mistakenly under-preserve a biological product: the bottles start to bulge or suck-in (the latter can also be caused by fragrance issues), fungal growth starts to appear or it starts to have an unpleasant odor. But do you know what signs to look for if your product is over-preserved? There is usually one noticeable sign of an over-preserved product: the customers who were consistently using your product

Bacillus Resilience to Oxidizers

  • MDG
  • June 18, 2020
For many of us, our day-to-day lives have changed quite a bit since the start of the coronavirus pandemic. We learned how to work from home, physically distance, use Zoom, cook homemade meals and use lots and lots of sanitizers and disinfectants. With the increased usage of these powerful cleaning supplies and washing them down drains, wastewater facilities are challenged with keeping their system’s natural ecology in balance. In our

Pandemic Recovery and Beyond

  • MDG
  • June 1, 2020
If you’ve tried to buy any hand sanitizer lately, you’ll know how difficult it is to find, let alone at a normal price! While the increased usage of sanitizers and disinfectants may be helping to protect us against the spread of germs, it has had a negative effect on the microflora balance in wastewater treatment lagoons. It’s also inspired some companies to market their bioaugmentation products as new solutions to this problem when

Clearing Up Fats, Oils & Grease

  • MDG
  • May 18, 2020
Fats, oils, and grease (FOG) that originate from restaurants, residential homes, and food processing facilities are commonly discharged into sewer systems. Picture things like vegetable oil and solid fats, such as lard. They eventually accumulate and can cause blockages in drainage systems, grease traps, and lift stations. Luckily for us (and our customers), FOG and other solids can be effectively broken down, digested and removed with the

Treating Lagoons with Bioaugmentation

  • MDG
  • May 7, 2020
Wastewater Lagoons can be found just about everywhere, in different climates and countries across the globe. They're used in wastewater treatment for a variety of different industries and while this means there are some differences in application, we've found that they often fall victim to many of the same challenges. Here's how our Biotifx® products work to combat some common issues. Bioaugmentation Works on SLUDGE Challenge: Within

Just like you and I, not every species and strain of bacteria are good at everything. We all have a unique set of talents and abilities. Bioaugmentation products are used when you want to improve an aspect of an environment biologically (i.e., eliminate foul bathroom odor, digest complex hydrocarbons in soil, reduce wastewater sludge).

Wastewater Lagoons:  Digging Yourself Out of Your Current Hole

  • Mike King
  • April 15, 2020
One of the biggest advantages to using bioaugmentation for lagoon wastewater treatment is that it can buy you time before your lagoon will need to be dredged. The specialized bacteria get to work on built-up sludge and can increase your capacity for a fraction of the price. However, I once spoke to a wastewater treatment professional that said, “if we need more lagoon space, we don’t dredge; we just dig another hole.” I knew dredging and

The Dangers of Hydrogen Sulfide Exposure

Wastewater and collection systems with anaerobic areas, FOG, or sludge build-up provide the perfect environment for hazardous Hydrogen sulfide (H2S) production. Because of this, it’s not uncommon for concentrations to climb above 1000 ppm! To understand the risks, check out the chart below to better understand the dangers associated at every level. ** Click to Enlarge What should you do if you're dealing with H2S?

8 Things That Don’t Belong in Your Plumbing

  • MDG
  • April 7, 2020
With more people staying home as we work to flatten the curve of COVID-19, residential plumbing systems are taking a bit of a beating. Our home plumbing, neighborhood collection systems, and large municipal sewer systems were probably not built for so many people being home at once. Do yourself and your neighbors a favor and think before you flush. So, what on the plumbing blacklist? As a rule of thumb, if it doesn’t dissolve (and stay
