The Role of Bacteria in the Industrial Wastewater Treatment Process Part 2

The Role of Bacteria in the Industrial Wastewater Treatment Process Part 2 Here’s the next part of our series on bacteria in the industrial wastewater treatment process. The typical growth rate curve of a bacterial culture, known as the bacterial growth rate curve, is a result of the four following phases of bacterial growth: The Bacterial Growth Cycle Lag Phase (Sometimes called initial phase). When bacteria are first introduced into an environment, little growth will take place until they adapt to their new environment. In fact, it generally takes several generation times before the bacterial numbers begin to significantly increase. In practice, the lag phase typically lasts three hours or longer.  Log Phase (Logarithmic Phase). Once full growth and cell reproduction is underway, the bacterial growth curve develops the log phase. This is the phase where the bacteria are rapidly dividing. This phase is limited by the food source and waste buildup. Stationary Phase. This phase occurs when some bacteria are growing and reproducing while others are dying. The actual number of living, viable organisms will remain fairly constant. Death Phase (Sometimes called log death phase). After a period of time, the environment becomes loaded with bacterial waste products, food supply is depleted, and the entire system begins to...

What are Microbial Products?

 What are Microbial Products? There are a number of products on the market that claim to be microbial products. So what are microbial products and how to they work? In the simplest terms, microbial products are composed of beneficial bacteria that are used to naturally, break down a waste product, environmental contaminant, or other complex organic compound. Typically, microbial products are used to clean fats, oils, and grease (FOG), to clean oil spills (as in bioremediation) or in agriculture to help provide nutrients to plants. Microbial products are effective in soil, water, and groundwater applications.   List of Microbial Products by Custom Biologicals   Beneficial bacteria, like all bacteria, work by producing substrate specific enzymes. Bacteria have the ability in their genetic material, to produce a wide variety of enzymes such as lipases (break down fats) and proteases (breaks down proteins). Bacteria are so efficient at producing enzymes that they are sometimes thought of as enzyme factories. These enzymes quickly solubilize various organic waste products making the waste available to the bacteria as a food source. The end product if this digestion is primarily more bacteria, carbon dioxide and water. Microbial products have a wide variety of uses including: Bioremediation – cleaning of petroleum and oil spills Wastewater Treatment...

Grease Trap Maintenance using Custom GT FAQ’s

Here’s some frequently asked questions about using Custom GT, a grease trap bacteria product, for grease trap maintenance. Grease Trap Maintenance using Custom GT Q. How does Custom GT work?  A. Custom GT contains billions of beneficial bacteria. These bacteria metabolize “eat” the organic components in the grease trap. The typical chemicals Custom GT encounters in a restaurant grease trap are Fats, Oils, and Grease (FOG), starches and proteins. Of these grease tends to be the largest component. Custom GT metabolizes theses organic compounds producing additional beneficial bacteria, carbon dioxide and water. Grease trap maintenance can be performed with regular use of Custom GT. Q. Do I still need to pump my grease trap? A. Yes. Although less frequently. Typically restaurants that pumped once a month will still need to pump their grease trap once a year to get the inorganic solids that accumulate in the bottom of the grease trap. So grease trap pumping is significantly reduced by should still be a part of your grease trap maintenance plan. Q. I’ve heard of grease trap enzymes. What is an enzyme? A. An enzyme is a protein that acts as a catalyst for many chemical reactions. Enzymes are substrate specific. That means there are different enzymes for proteins, grease,...
