Bacterial Treatment

Issue: A Fortune 500 company has regular waste strength exceedances at one of its food processing facilities. Action: The high levels are traced to a grease trap. Treatment with bacterial additive produces four consecutive quarters of compliance and is now included as standard procedure.

Four Star Restaurant

Overview: A Four Star restaurant has a nearly new septic system headed for premature failure due to excessive influent waste strength. They also struggle with odor problems. Solution: Additional grease trap capacity and VBT aeration are installed ahead of the existing recirculating gravel filter. Odor issues are resolved immediately and compliance limits are met. …

Dinner Restaurant

Overview: A northern Wisconsin dinner restaurant has a failed septic system. Another contractor proposes a treatment technology to handle their high strength discharge that makes the project unaffordable. Solution: VBT aeration is installed at approximately ¼ the cost of the previously proposed technology and effluent compliance limits are met. …

Winery Discharge

Overview: An Oregon winery produces 10,000 GPD discharge with a BOD5 of 10,000 – 15,000 mg/L. The discharge is too strong for the local wastewater treatment plant to process and must be trucked off site. Solution: Build an aerobic onsite treatment system using MBD, Micro Bubble Diffusion, aeration to reduce waste strength to 300 mg/L…

Endurance Test

Overview: A chicken processing facility in the North Eastern US is concerned about surface aerators in use at their facility. They are 75 HP units and the effectiveness per HP is in question. The possibility of using Vacuum Bubble Technology Aerators is presented to the company. Since the MBD Model 600 Series aerator proposed has…

Meat Canning Facility

Overview: An Iowa company has a one million gallon industrial waste lagoon filled to capacity with 100% sludge. The high strength waste consists of byproducts of canned meat production: i.e. grease, fat, and vegetable matter. Odor issue is extreme. Solution: The installation of four Vacuum Bubble Technology Model 600 units show immediate results. Odor issue…

Lift Station Odor Control

Overview: A North Carolina Service Company needs a solution for lift station odor control. Several efforts to reduce the odor include rental of an air scrubber system with unsustainably high cost. Solution: Installation of MBD Aerator Model 200 results in elimination of odors within 24 hours. …

Grinder Tank Odor Control

Overview: North Carolina residents complain about odor emanating from grinder tanks connecting their homes to the local wastewater treatment plant. Solution: Install MBD aeration to reduce hydrogen sulfide (H2S). Pre-aeration H2S levels ranges from 0.009 ppm to 0.560 ppm with a mean of 0.0554 ppm. After VBT treatment H2S levels rarely registers over 0 ppm. …

Sludge Reduction – Five Lagoon System

Overview: A Texas wastewater treatment plant has a five lagoon system of 24 surface acres. Average influent is 1.2 million gallons per day. Regulation requires sludge removal at 36-48” of depth in their 8 foot deep lagoons. Goal – reduce sludge without impacting water quality. Solution: Install seven (7) MBD Model 600 aerators totalling 21 HP. …

Electrical Efficiency

Overview: A Minnesota community experiences odor problems in a municipal lagoon serving a turkey processing plant. The engineered solution is adding aeration to minimize the odors. Solution: The odor problem is corrected upon MBD installation. In addition, the MBD solution with six 3 HP Model 600 units is $387,000 less than the second place bid. Electrical savings…
