Description

 

Large-scale systems combining the benefits of the small scale systems with a high capacity and outstanding effluent quality. These systems are capable of treating up to 200 m3/d of waste water on average. Customized design is available for higher flowrates.

 

Curtain ultrafiltration membrane (RUF) is a group of submerged ultrafiltration membrane composed of elements. Monolithic curtain ultrafiltration membrane can be composed of various sizes and standards according to the requirements of customers MBR membrane tank. MBR applications small footprint, effectively retain sludge, ensure the quality of the effluent. Products used for the production of higher quality recycled water, surface water and water purification mentioned standard.

Key features here are reliability, redundancy, and long-lasting performance. MBR-K systems are built for decades, although they can be designed with a potential site upgrade in mind.

MBR advantages

1. Low footprint and construction area;
2. Excellent effluent quality and solids retention; SDI≤3;
3. Enhanced biological degradation and treatment efficiency; lower operational cost;
4. Better nutrients removal and ammonia oxidation;
5. Modular design and flexible operation.

 

Commercial and industrial applications:

1) New installations for pharmaceutical, alcohol, leather, paper/pulp, food production, and other industries with high organic content in the wastewater, where conventional treatment doesn’t allow achieving required water quality;
2) Agricultural and livestock effluent treatment;
3) Upgrading of the conventional/old treatment processes. MBR provides higher treatment efficiency with lower space requirements;
4) Portable/temporary effluent treatment for industrial, mining or construction sites, especially at the remote locations;
5) Car wash and laundries.

MBR effluent water quality

 

Note: Chinotech MBR reactors are capable of meeting not only the regular effluent sewage requirements (GB8978-1996) , but they also satisfy the national standard for recycled water (GB/18919-2002).

 

 

Municipal and residential sewage treatment

1)Office centers, residential areas, hospitals, hotels, schools and colleges, sport centers, and other types of civil applications;

2) Sewage treatment for remote locations: tourist resorts, scenic areas, camping sites, villas, small settlements, toll stations, military camps, etc.;

3) Temporary sewage treatment (in addition to existing facilities) for special public events, competitions, or in other cases when increase load is expected.

 

MBR membrane features

1. High flux rate, up to 55 LMH (L/m2*H). Asymmetric membrane structure reduces flow resistance, and improves hydraulic properties and permeability;
2. Reinforced PVDF membrane structure for mechanical strength. Membranes are less susceptible to being damaged during the filtration, backwashing or chemical cleaning;
3. Unique anti-fouling design; specific design of aeration nozzles prevents extensive membrane fouling, extending the operation time;
4. Wide range of membrane sizes and configurations for optimal system design;
5. Sealed fiber end design; bottom end of each hollow fiber is sealed; permeate is collected through the top opening preventing the contamination of clean water with sludge and bacteria;
6. Stable operation and long service life.
