Industrial processes play a vital role in powering economies and providing essential goods and services. However, these processes often generate large volumes of wastewater that can be laden with pollutants, chemicals, and other contaminants harmful to the environment and public health. To address these challenges, membranes have emerged as cutting-edge technology for industrial wastewater ...
Capacity: 500m³/d Process: MBR+NF+RO+DT The effluent water quality meets the discharge standard. Jiarong- headquartered in Xiamen, China- was founded in 2005. We are a specialist in industrial membrane separation process. The core technology of Jiarong includes Disk-tube RO membrane system, Spiral-tube RO membrane system, Tubular UF membrane system and Micro-tube NF/RO membrane system etc. ...
Application: Chemical wastewater Scale: 20 tons / hour * 2 Process: UF-MTNF-MTNF, UF-MTRO-MTRO Time: 2015 INTRODUCTION In the treatment of high-salt, high-temperature, high-pH chemical production wastewater, Jiarong uses a tubular ultrafiltration membrane plus two-stage nanofiltration membrane treatment ...
More ultrafiltration membrane system details here! CHARACTERISTICS OF NANOFILTRATION CERAMIC MEMBRANE ELEMENT Chemical, mechanical and thermal stability Ability of steam sterilization and back flushing High abrasion resistance High fluxes High durability Bacteria resistance Possibility of regeneration Dry storage after cleaning OVER VIEW OF ...
In the production process of rolling, galvanizing, spraying, metal cutting, oil and alkali refining, a large amount of oily wastewater is produced. JIUWU company has been successfully applied to the treatment of oily wastewater with ceramic membrane technology, and there are many typical cases. JIUWU company can provide the overall process package of emulsified oily water filtration system. The ...
In the second WWTP, the percentage of cultivable resistant E. coli did not display a considerable change. During laboratory-scale membrane filtration of WWTP effluents using ultrafiltration (UF) and nanofiltration (NF) membranes, all E. coli, including those resistant to antibiotics, were removed completely. The results imply that UF and NF ...
To evaluate the infectious risk of norovirus (NoV) in various applications of the reclaimed water, five types of ultrafiltration (UF) membrane treatments were considered: (1) coagulation with low pH + UF membrane process, (2) UF membrane process alone, (3) UF + ultraviolet (UV) irradiation ...
This work assessed the potential of nanofiltration (NF) and reverse osmosis (RO) to treat acid streams contaminated with metals, such as effluent from the pressure oxidation process (POX) used in refractory gold ore processing. NF and RO were evaluated in terms of rejections of sulfuric acid and metals. Regarding NF, high sulfuric acid permeation (∼100%), was observed, while metals were ...
The purpose of the research is to study the major role of reverse osmosis (RO) and nanofiltration (NF) process which can contribute to the removal of this inorganic element from brackish water. For this reason, two RO and two NF membranes have been used to reduce boron and total salinity of brackish water. ...
A combination of membrane bioreactor (MBR) and nanofiltration (NF) was tested at pilot-scale treating textile wastewater from the wastewater treatment station of a textile mill in Wuqing District of Tianjin (China). The MBR-NF process showed a much better treatment efficiency on the removal of the chemical oxygen demand, total organic carbon, ...
Ion-exchange tap water demineralization for process water preparation results in a saline regeneration wastewater (20–100 mS cm−1) that is increasingly problematic in view of discharge. A coupled nanofiltration–membrane distillation (NF-MD) process is evaluated for the recovery of water and sodium chloride ...
The purpose of the research is to study the major role of reverse osmosis (RO) and nanofiltration (NF) processes, which can contribute to the removal of cadmium ions from model water and wastewater from the battery industry. For this reason, two RO and two nanofiltration membranes have been used. The effects of feed pressure, ...

A nanofiltration (NF) membrane pilot plant was tested to treat water from a spring located in the Tula Valley. ...
There is considerable interest in minimizing the chlorine residual in Japan's tap water because of increasing consumer complaints about the chlorinous odor of drinking water. However, minimization of the chlorine residual requires stricter control of biodegradable organics in finished water to ensure biological stability during water distribution. In this context, we investigated the ...
A combination treatment of Ca-precipitation and nanofiltration membrane was studied to remove arsenate from water. The selected nanofiltration membrane was an amphoteric charged membrane, proved by the results of ATR-FTIR spectra and zeta potential. ...
This study is focused on a technical-economic analysis of greywater treatment by a direct nanofiltration (NF) process or by a submerged membrane bioreactor (SMBR) for on-site recycling. The aim of this paper is to analyse the cost of recycled water for two different configurations (50 and 500 inhabitants) in order to demonstrate the relevance of ...
Today, a vast majority of crossflow filtration installations utilise polymeric membranes. Virtually all commercial nanofiltration membranes are polymeric. Nanofiltration (NF) is a crossflow, pressure driven process that is characterised by a membrane pore size corresponding to molecular weight ...
