BZT Waste Digester vs. Filamentous Bacteria - Pt. 2
10/07/11 16:11
We have received some questions concerning the efficacy of our products relating to wastewater, in particular BZT’s role in dealing with filamentous bacteria. This is two of two Treatment Summaries I am posting to provide an understanding of how BZT Waste Digester works to reduce or eliminate this issue. (Bruce)
Biobed Anaerobic Reactor - Aeration Basin - Ethanol Plant - BZT® Waste Digester
The Situation
An ethanol plant was experiencing upsets in its biobed reactor and the biological activity of the bed was being seriously impaired. The plant was also experiencing heavy foaming and was overcome by filamentous bacteria throughout the wastewater treatment plant.
The Solution
United-Tech proposed a bioaugmentation program that consisted of the addition of BZT® Waste Digester to the biobed and the aeration basin. The treatment was designed to provide the hydrolytic breakdown of the starches, proteins and the cleaning solutions that were used in the plant cleanup operations, all of which were causing upsets in the various stages of wastewater.
The Results
The addition of BZT® Waste Digester increased the heartiness of the biobed allowing it to survive upsets. The filamentous problem has been eliminated along with the solids being greatly reduced. Since starting the maintenance program the facility has not had the need to purchase activated sludge. This savings has more than offset the cost of the program.

Odor & Sludge Reduction - Wastewater Treatment Rendering Facility - BZT® Waste Digester
The Situation
A major rendering facility was experiencing problems with its Wastewater Treatment Plant because of high influent loading during the summer season. Odor from the plant was headlined in news articles and foaming attributed to filamentous bacteria, which plugged pumps and decreased the plant's efficiency.
The Solution
United-Tech proposed a bioaugmentation program that consisted of the addition of BZT® Waste Digester to the system. It was proposed that an initial seed application be performed followed by regular weekly maintenance applications. The treatment program was designed to:
• Reduce solids
• Enhance Stability
• Reduce/eliminate odor
• Breakdown H2S
• Reduce the total overall sludge volume
• Increase plant capacity and efficiency
• Increase plant ability to handle upsets and shocks
The Results
Within one month, solids were reduced by up to 20%. The odors had all but disappeared. The foaming and filamentous problems were greatly reduced after two months, and eliminated after three months. The program provided positive payback within three months, attributed to:
• Reduction in hauling costs
• Reduction in polymer usage
• Elimination of chlorine
The program has demonstrated the broad ranging effects of BZT® Waste Digester and its ability to reduce the odor in the surrounding community and save thousands of dollars.

Pulp/Paper Sludge Waste Treatment
05/18/11 12:14
Manufacturing paper products comes with hefty cleanup responsibilities, typically resulting in either routine, expensive dredging of settling ponds, or relatively inexpensive bioaugmentation using beneficial bacteria and enzymes to do the dirty cleanup work.
United-Tech provides sound, environmentally responsible solutions to waste control issues. That said, we also like to save money for our customers.
(Before Treatment)
Case in point: A wallboard manufacturer faced routine dredging of two settling ponds. Each event carried a hefty price tag of well over $1 million dollars per year. Heavy paper/pulp sludge build-up also strained their regulatory discharge limits, leaving the settling ponds at risk.
United-Tech developed a custom bioaugmentation program using BZT® Waste Digester. Seed and maintenance doses were applied regularly, and data was collected and continuously monitored. By the end of the program (less than a year), sludge volumes not only decreased, but also one of the ponds stood empty and continued to serve as a standby pond.
From start to finish, the company went from utilizing two settling ponds, plus a large finishing lagoon, to operating only one pond and having a backup pond. Also, the effluent remained cleaner than the historical flow.
Summary: Success exceeding expectations. This is what we achieve at United-Tech.
