Wastewater Treatment
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. …
Read MoreWinery 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…
Read MoreEndurance 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…
Read MoreMeat 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…
Read MoreLift 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. …
Read MoreGrinder 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. …
Read MoreSludge 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. …
Read MoreElectrical 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…
Read MoreSludge Reduction
Overview: An Iowa Wastewater Treatment Facility has a three pond lagoon system that receives 250,000 GPD influent. Sludge levels are 26” – 32” in 5’ deep lagoons and sludge removal is required. Solution: Four Model 600 MBD units are installed totalling 12 HP. Within 14 months sludge is reduced to an average of 3” – an…
Read MoreNorth Carolina Hog Lagoon
Overview: A North Carolina company seeks to minimize pumping frequency and expense for solids removal from hog lagoons. Solution: Install MBD Aeration based on lagoon volume. Systems tested have an average sludge reduction from 5’ to 3.5’ over a 60 day period. Electrical cost to reduce BOD from 400 feeder pigs in this test is…
