NICO systems support aerobic treatment, odour management, oxidation, polishing, and water reuse across industrial estates, factories, food processors, commercial facilities, and municipal plants.
Plants may experience unstable oxygen, high aeration demand, septic zones, odour, sludge problems, and influent shocks.
Vietnam’s industrial and urban growth is increasing treatment demand. Seafood processing, food and beverage, textiles, rubber, paper, manufacturing, industrial estates, hotels, and municipal facilities produce wastewater with different flows, loads, solids, colour, salinity, and objectives.
Plants may experience unstable oxygen, high aeration demand, septic zones, odour, sludge problems, and influent shocks. NICO’s ultra-fine bubbles remain suspended longer than coarse bubbles, increasing gas contact.
Micro-aeration in anaerobic digestion must be precisely engineered to avoid disrupting the intended anaerobic biology.
Choose a compact mixer for compatible existing infrastructure, a matched mixer-and-pump loop, or an automated skid with gas supply, sensors, alarms, interlocks, and monitoring. Air supports general aeration oxygen addresses higher demand ozone supports selected oxidation with appropriate materials and safeguards.
NICO reviews average and peak flow, BOD, COD, solids, oil and grease, ammonia, salinity, pH, temperature, colour, odour, tank dimensions, existing aeration, discharge limits, and reuse targets. Complex effluent should undergo laboratory testing or a pilot.
Nanobubbles improve gas transfer but do not replace screening, solids removal, biological-process design, filtration, sludge management, or regulatory compliance.
Establish a representative baseline before installation, including normal and peak production periods. After commissioning, track dissolved oxygen by tank zone and time alongside flow, energy, sludge, odour observations, and relevant laboratory indicators. Sampling locations and methods should remain consistent.
A reduction in blower runtime is valuable only if oxygen, settling, effluent quality, and biological stability remain acceptable. Changes in production, chemicals, return sludge, temperature, or influent must be recorded so they are not incorrectly attributed to the nanobubble system.
Ozone dose and contact requirements should be confirmed through treatability testing. Residual ozone, off-gas, worker exposure, downstream biology, and material compatibility must be controlled.
