![]() The evaluation has been deemed successful by the plant manager, and further treatment is planned elsewhere in the pond system where sludge buildup has occurred over time. ![]() The results from several areas of the lagoon are shown in the graph in Figure 1.įigure 1: Sludge depth changes with treatment in noted areas of the lagoon Ten days later, the second addition of BioPlus BA3903 was added after measurements showed a reduction of sludge depth from 15 to 2 feet in one area and 8 feet to 2½ feet depth in an adjacent area of the lagoon. In the test area, 15 feet of sludge was initially measured. A plan to evaluate a section of the lagoon was established, and measurements made to determine the volume of sludge in that test area.īioPlus BA3903 was applied at recommended dosages. The application can be at higher dosages in problem areas for faster sludge reduction. BioPlus BA3903 is formulated as weighted ‘spikes’ which are applied over a broad area to reduce the overall sludge layer in a lagoon. The product was developed for use in the biological degradation of organic industrial sludge accumulated at the bottom of lagoons. A trial using the BioPlus BA3903 product was started on one area of the pond to determine removal efficacy.īioPlus BA3903 contains a specially formulated blend of naturally occurring, but adapted, high-performance microorganisms, together with some enzymes and nutrients for low dissolved oxygen (DO) conditions. A solution utilizing Veolia’s BioPlus BA3903 was proposed to strategically add to the pond. After a site audit, the pond sludge composition was identified as high in organic composition. Pond maintenance was planned, including dredging, but Veolia was contacted for input on options to improve conditions in the pond moving forward.
