Ultrasonic algae control solution for wastewater reservoirs industry - Water and Wastewater

• Effluent treatment
• Lower Biochemical Oxygen Demand (BOD)
• Comply with wastewater regulations

• Comply with discharge standards for TSS, pH
• Safe wastewater discharge
• Algae can increase BOD levels

An important issue to consider in wastewater reuse and treatment is algae growth, which is relatively common in warm and nutrient-rich waters. Treated wastewater usually contains high levels of nutrients that can cause algae blooms on the water surface of storage ponds and clog irrigation systems (?lters, emitters, distribution pipes).

Furthermore, some freshwater algae can form harmful algal blooms (HABs), and these speci?c species create health hazards for humans and animals by producing toxins and bioactive compounds that deteriorate the water quality.

Although there are several methods to treat wastewater, this article focuses on stabilization ponds (also called lagoons or waste stabilization ponds). These types of ponds and lagoons consist of in-ground earthen basins in which the waste is detained for a specified time (retention time) and then discharged.

The size and depths can vary, as well as the degree of treatment. Lagoons are typically classified by their degree of mixing and amount of oxygen dissolved in the water. Examples of lagoons are anaerobic lagoon, facultative lagoon, aerobic lagoon, partial-mix aerated lagoon, and completely mixed- aerated lagoon.
