NICO Nanobubbles in Wastewater Treatment & STP

NICO Nanobubble India Co. is pioneering the use of nano bubble technology in Wastewater Treatment Plants (WWTP) and Sewage Treatment Plants (STP). Our innovative approach integrates advanced nanobubble water and wastewater treatment processes, ensuring greater efficiency, sustainability, and operational excellence. NICO Nanobubbles exhibit unique properties that make them highly effective in improving wastewater treatment with nanobubbles across WWTP and STP applications.

Key Features of NICO Nanobubbles

• High Surface Area-to-Volume Ratio: The small size of NICO Nanobubbles provides a significantly larger surface area, promoting more efficient interactions with contaminants.
• Stability: Unlike larger bubbles that quickly rise and burst, NICO Nanobubbles are stable and remain suspended in water for extended periods, allowing prolonged treatment effects.
• Efficient Gas Transfer: NICO Nanobubbles improve the transfer of gases such as oxygen and ozone into the water, enhancing the availability of these gases for nano bubble technology in water purification processes.

NICO Nanobubble Solutions for Industrial and Municipal Wastewater

NICO offers application-specific nanobubble generator systems for industrial wastewater treatment, municipal sewage treatment, and drain management. NICO DRONA is designed for industrial effluent treatment plants (ETPs) and industrial wastewater applications, while NICO VARUNA is designed for municipal sewage treatment plants (STPs), sewer systems, and open-drain treatment. Both solutions can be evaluated for integration into existing infrastructure to improve gas transfer, support treatment processes, and optimize plant performance according to site-specific requirements.

Benefits of NICO Nanobubbles in STP & WWTP

Enhanced Oxidation & Treatment Efficiency

• Advanced Oxidation Processes (AOP): NICO Nanobubbles facilitate the generation of reactive oxygen species (ROS), such as hydroxyl radicals (•OH), which are highly effective in breaking down complex organic pollutants.
• Improved Contaminant Removal: The increased reactivity and contact area provided by NICO Nanobubbles enhance the degradation of organic and inorganic contaminants, including those from pharmaceuticals, pesticides, and industrial chemicals.

NICO DRONA for Industrial Wastewater Treatment

NICO DRONA is NICO’s dedicated nanobubble generator system for industrial wastewater treatment. It is designed to enhance oxygen transfer and support biological treatment processes in industrial ETPs, helping operators manage organic loads and improve wastewater treatment performance. The system can be evaluated for industries generating complex effluents, including textile and dyeing, pharmaceutical, chemical, food processing, and other manufacturing operations. By improving oxygen availability in suitable biological treatment processes, NICO DRONA can support microbial activity and the breakdown of biodegradable organic matter, contributing to the reduction of biochemical oxygen demand (BOD) and chemical oxygen demand (COD). Depending on wastewater characteristics and treatment objectives, nanobubble systems can also be assessed as part of oxidation and pre-treatment processes for challenging industrial effluents. NICO DRONA can be considered for integration into existing ETPs, aeration tanks, equalization basins, and suitable side-stream treatment arrangements. System selection depends on wastewater composition, flow rate, oxygen demand, operating conditions, and the required discharge or reuse standards.

NICO VARUNA for Municipal Sewage Treatment and Drain Management

NICO VARUNA is NICO’s dedicated nanobubble solution for municipal sewage treatment, STP performance improvement, and drain management. The system is designed to support oxygen transfer in sewage and wastewater, helping improve conditions for biological treatment and the breakdown of organic pollutants. It can be evaluated for existing municipal STPs, sewer networks, and open drains where oxygen depletion, organic pollution, and odour generation are operational challenges. In sewage treatment applications, enhanced oxygen transfer can support aerobic microbial activity and help improve treatment stability. For drain-management projects, appropriately configured oxygen or ozone nanobubble treatment may be evaluated according to the characteristics of the wastewater and the required treatment objectives. The system configuration, gas selection, and operating parameters should be designed for the specific application. NICO VARUNA can be considered for retrofit projects where operators seek to improve existing treatment performance without relying solely on major civil expansion. Actual outcomes depend on flow rate, wastewater loading, retention time, initial water quality, and the existing treatment process.

Environmental and Economic Advantages

• Reduced Chemical Usage: By improving the efficiency of oxidation processes, NICO Nanobubbles minimize the need for chemical oxidants and coagulants, leading to cost savings and reduced environmental impact.
• Energy Efficiency: The enhanced gas transfer and reaction kinetics associated with NICO Nanobubbles result in lower energy consumption compared to traditional aeration and treatment methods.
• Odour Control: Enhanced oxygenation and aerobic conditions prevent the formation of foul-smelling anaerobic zones, significantly improving odour management in treatment facilities.

Aeration Energy Optimization and Operational Savings

Aeration is one of the major energy-consuming processes in biological wastewater treatment plants. NICO Nanobubble Technology enhances gas transfer and dissolved oxygen management, helping optimize aeration performance and reduce dependence on conventional energy-intensive aeration. Depending on the existing system, wastewater loading, and operating conditions, nanobubble integration deliver 15–40% aeration energy savings compared with conventional aeration approaches. By improving oxygen transfer efficiency, NICO DRONA can support energy optimization in industrial wastewater treatment plants (ETPs), while NICO VARUNA can support aeration optimization in municipal sewage treatment plants (STPs). Actual savings depend on the existing aeration equipment, oxygen demand, treatment configuration, and operating strategy. Monitoring energy consumption alongside dissolved oxygen, COD, BOD, and treated effluent quality helps quantify performance improvements following implementation.

Operational Improvements

• Optimized Performance: NICO Nanobubbles streamline the treatment process, potentially eliminating the need for additional treatment stages and reducing operational complexity.
• Lower Operational Costs: The combination of reduced chemical usage, lower energy requirements, and improved treatment efficiency leads to significant cost savings for nanobubble solutions for industrial wastewater operations.

Industrial Applications of Nanobubble Wastewater Treatment

NICO DRONA can be evaluated for a range of industrial wastewater applications, including:

• Textile and Dyeing Wastewater: Treatment support for effluents containing dyes and high organic loads.
• Pharmaceutical Wastewater: Oxygenation and treatment support for wastewater containing complex organic compounds.
• Chemical and Petrochemical Effluent: Application-specific oxygen transfer and oxidation support for industrial wastewater.
• Food and Beverage Processing: Support for biological treatment of wastewater with high biodegradable organic loads.
• Pulp and Paper Wastewater: Treatment support for organic pollution and process effluent.
• Industrial Water Reuse: Potential integration into pre-treatment and treatment processes supporting water recovery and reuse. NICO VARUNA is intended for municipal sewage and drain-management applications, including sewage treatment plants, sewer networks, and open drains. The appropriate system is selected according to wastewater characteristics, flow rate, treatment requirements, and existing infrastructure.
