Industrial Brackish Water Desalination Series Reverse Osmosis Membrane Elements
Jozzon JBW series four-inch brackish water desalination membrane elements (JBW-4040, JBW-4040-HF) adopt dry storage and fiberglass winding technology. They are designed for small and medium-sized systems with poor influent water quality and high water production requirements.
Product Overview
JOZZON's 4-inch brackish water desalination membrane elements can meet various customer needs and are suitable for systems with slightly poor feed water quality and high product water quality requirements. These membrane elements are dry-type with a fiberglass-wound outer shell, capable of withstanding higher operating pressures and suitable for multi-element systems.
Features & Benefit
1.Dry Membrane Element for Easy Storage and Transportation
The dry preservation process eliminates the need for soaking in antiseptic fluid, and there is no risk of microbial growth during storage and transportation, and the flushing time before startup is shorter.
2.Fiberglass Casing Wrapped with Excellent Pressure Resistance
The outer layer is reinforced with fiberglass reinforced plastic (FRP) winding, which can withstand higher operating pressure, is suitable for multi-component series systems, and has reliable structural strength.
3.Adapt To Poor Incoming Water Quality
It is specially designed for surface water, groundwater and highly polluted water sources with a salt content of less than 5000ppm and large fluctuations in water quality. It has good water inlet adaptability.
4.Meet High-yield Water Quality Requirements
It can still maintain stable desalination performance even when the incoming water quality is low, meeting the strict standards for pure water or ultrapure water in the food, medicine, electric power and other industries.
