Water Treatment Field Roles & Problem-Solving

Key Roles

Supplies high-purity oxygen for aerobic biological treatment (e.g., activated sludge process), enhancing microbial activity and pollutant degradation efficiency.

Provides oxygen for ozone generators in advanced oxidation processes, supporting disinfection and removal of refractory organic pollutants.

Delivers nitrogen for inert protection of water treatment equipment (e.g., membrane modules) and anaerobic digestion systems, preventing oxidation and corrosion.

Supports membrane aeration processes in wastewater treatment, improving oxygen transfer efficiency and reducing energy consumption of aeration systems.

Problems Solved

Addresses low oxygen transfer efficiency of traditional aeration systems, accelerating pollutant degradation and shortening water treatment cycles.

Resolves instability of ozone generation caused by impure oxygen, ensuring disinfection effect and meeting strict water discharge standards.

Mitigates equipment corrosion and membrane aging due to oxygen exposure, extending the service life of water treatment facilities.

Reduces reliance on external gas cylinder supply, avoiding supply disruptions and high logistics costs in remote or large-scale water treatment plants.

FAQ

1.What gas purity is suitable for aerobic biological water treatment?
Oxygen purity of 93-95% is optimal, balancing treatment efficiency and operational costs; higher purity (99%+) is recommended for ozone generation.

2.How to match the unit's output with the scale of the water treatment plant?
NEWTEK's engineers calculate required output based on water volume (m³/d), pollutant load (BOD/COD), and treatment process, ensuring precise matching without waste.

3.What is the installation space requirement for a 10,000 Nm³/h unit?

It requires ~800-1,000 m² of flat space, with modular design allowing vertical layout to save area for small plants.

4.How often does the unit need maintenance, and what is the cost?
Routine maintenance is performed every 6 months (filter replacement, parameter calibration); annual maintenance cost is ~2% of the equipment price, lower than industry averages.

5.Can the unit be integrated with existing water treatment automation systems?

Yes-it supports communication protocols such as Modbus and Profinet, seamlessly connecting to the plant's central control system for unified management.

What backup measures are available for unexpected failures?The unit is equipped with a redundant core component design; NEWTEK provides 24-hour emergency technical support, and on-site troubleshooting is available within 48 hours in major regions.
