SDN Liquid treatment
Sewage Water Treatment Equipment - MBR
Integrated sewage treatment equipment - MBR
Basic Introduction
Compared with traditional processes, the MBR process can functionally replace the secondary sedimentation tank. At the same time, the effect is to increase the sludge concentration in the aeration tank, reduce the area occupied by the aeration tank, and greatly reduce the area occupied by the entire system, saving investment costs. The mud production is only 30% to 50% of that of traditional processes.
Main features
1. Realize cluster networking, automatic operation, remote monitoring, unmanned operation, and low maintenance costs.
2. By adopting frequency conversion technology and the most advanced energy-saving supporting facilities, low energy consumption and low operating costs are achieved.
3. The equipment has low operating noise, no odor, and minimal impact on the surrounding environment.
4. Easy maintenance, online cleaning of membranes, foolproof operation.
5. Durable to impact loads, with low sludge production.
6. Small footprint.
Scope of use
01 Municipal sewage treatment : Upgrading and Renovation , Incremental expansion.
02 Black and odorous water treatment : Pollution interception and source control treatment.
03 Village and town sewage treatment : Decentralized sewage treatment and emergency treatment of sewage.
The company provides hollow fiber or flat membrane application technology
01 Optimize high-throughput design for high cost-effectiveness;
02 Asymmetric large aperture design, high pollution resistance;
03 Super strong antioxidant material, suitable for a long service life;
Mainly intercept colloidal substances, macromolecular substances, particles, bacteria, viruses, and protozoa in the original solution, and remove them through concentrated liquid discharge and backwashing.
Typical Application - Hospital Wastewater Treatment
Our company can provide services for hospital wastewater treatment, including MBR integrated wastewater treatment system effluent that meets the comprehensive medical and other medical institution water pollution discharge standards specified in the Medical Institution Water Pollutant Discharge Standards (GB18466-2005).

| 1 | pH | 6-9 |
| 2 | Chemical Oxygen Demand (COD) concentration (mg/L) | 60 |
| Maximum allowable emission load (g/(bed · d)) | 60 | |
| 3 | Biochemical Oxygen Demand (BOD) concentration (mg/L) | 20 |
| Maximum allowable emission load (g/(bed · d)) | 20 | |
| 4 | Suspended solids (SS) concentration (mg/L) | 20 |

Special medical wastewater can only enter the MBR integrated sewage treatment system after pre-treatment.
| Serial Number | Wastewater Name | Treatment process |
| 1 | Radioactive wastewater | Decay pool |
| 2 | Wastewater containing heavy metals | Flocculent settling |
| 3 | Infectious wastewater | Contact disinfection |
MBR product series
The MBR product series can be freely combined and connected in parallel to 5000 tons per day. It is divided into A series and B series according to the water quality requirements of the treated effluent.
Series A: The effluent quality meets the surface level four standards of the Water Pollutant Discharge Standards for the Minjiang and Tuojiang River basins in Sichuan Province (DB51).
Series B: The effluent quality meets the Class A standard in the Pollutant Discharge Standards for Urban Wastewater Treatment Plants (GB18918-2002).
