Xiamen Jiarong Technology Corp., Ltd is a high-tech company that specializes in membrane separation technology and is dedicated to the development of environmentally friendly water treatment and industrial production cleaning processes. DT/ST/MT membrane technology is a major advancement in the field of membrane module technology. With more than ten years of practical experience in industrial membrane technology, Jiarong Technology has continuously developed a series of products and systems, widely used in landfill leachate treatment, desulfurization wastewater treatment, coal chemical wastewater, and oil and gas field wastewater treatment.
Landfill leachate is a kind of wastewater with extremely complicated composition. The content of CODcr, ammonia nitrogen and heavy metals are very high. In recent years, the use of two-stage DTRO technology to treat landfill leachate has become a very effective method.
The main technical characteristics：
–
Pressure level: medium and low pressure 75bar, medium pressure 90bar, medium and high pressure 120bar, high pressure and ultrahigh pressure more than 160bar;
High anti-pollution, excellent performance and stability;
Simple operation and maintenance.
For the MBR + NF / RO treatment process. The total recovery rate of leachate NF-RO process is approximately 60%,which produces 40% of the concentrated liquid, and 40% of the concentrated liquid cannot be reused. DTRO membrane is suitable for the treatment of high-salt and high-concentration sewage. It can re-concentrate the concentrated liquid to reduce the volume of concentrated liquid and treat the concentrated liquid which cannot be reused.

As a mature enterprise specializing in membrane leachate treatment, Jiarong has rich experience in DTRO membrane application and has achieved more than 200 DTRO project. After successful development in partnership with several leachate engineering companies and design institutes. The process of reducing the concentration of NF-RO concentrated liquid by using DTRO membrane technology was implemented. The process is simple and reliable, no pretreatment is required, and the effluent reaches the standard stably.
In many industrial wastewater treatment processes, separation of monovalent salts, divalent salts, and high-priced salts is required. Jiarong has developed a variety of combination processes that can accurately screen materials with different molecular weights and different price positions.
The main technical characteristics：
–
Wide applicability
Various models of membrane optional
Stable operation, high anti-pollution ability
In the industrial production process, some materials are often unable to reach the user's desired concentration and membrane equipment is required for further concentration. Jiarong has many project experiences in the field of material enrichment, covering pharmaceuticals, food juices, enzyme preparations, etc.
The main technical characteristics：
–
Low energy consumption;
Concentration at normal temperature;
Investment savings;
Low operating costs.
Wastewater discharged from industrial production processes often needs to be recycled after comprehensive treatment to achieve zero emissions. In order to achieve zero emissions, a variety of process combinations are required, including multi-stage separation membrane systems and evaporators. Thanks to high filling area, Jiarong ST/MT membrane modules enable some process sections with higher water ingress TDS to achieve higher-enrichment than conventional spiral membranes. At the same time, they have more economical investment and convenient maintenance than DT.
The main technical characteristics：
–
Recovery rate 80-90%
Water production TDS<1000mg/L
Concentrated water TDS>13%
Membrane flux: 10-20L/m2h
Pressure level: 75bar, 90bar, 120bar
