Hydranautics SWC seawater reverse osmosis membranes
In today’s world, freshwater scarcity is a global problem affecting millions of people. To address this problem, Hydranautics has developed a range of reverse osmosis membranes called SWC Sea Water Composite to meet the demands of the desalination industry.
SWC membranes have improved productivity and salt rejection for more than two decades, while reducing their environmental impact. These membranes come in a variety of innovative formulations depending on the level of seawater salinity required.
Each SWC membrane formulation offers the highest productivity and salt rejection rates in the industry, combined with optimized flux, low clogging and low energy consumption. This exceptional performance and consistency has created a high demand for SWC membranes in seawater desalination and high TDS (Total Dissolved Solids) industrial wastewater treatment applications, including conventional and hybrid designs.
SWC membrane technology is highly effective and can help solve freshwater scarcity problems around the world. In addition, these membranes are resistant to clogging and fouling, which means they can last longer and reduce maintenance costs.
SWC4 membranes are the most effective at rejecting salt and treating different levels of seawater salinity, producing low TDS permeate. These membranes are very popular in the treatment of seawater and highly saline waters. In addition, they are available in two types of variants: LD and MAX.
Low-difference LD® technology variants are offered to minimize colloidal clogging when used with conventional pretreatment equipment. These membranes offer consistently low feed pressure and the longest duration between two successive cleanings.
The MAX models, on the other hand, have an active membrane surface area of 440 square feet (40.9 m2). They provide excellent performance with high TDS and boron removal in warm waters.
In summary, SWC4 membranes are the ideal solution for the treatment of seawater and highly saline water. The LD and MAX variants offer different benefits depending on the application. If you are looking for a high quality and efficient water treatment solution, SWC4 membranes are an excellent choice.
SWC5 membranes are an excellent choice for those seeking to optimize salt rejection and permeate fluxes. These membranes are particularly useful when lower permeate TDS and lower feed pressures are needed. In addition, SWC5 membranes offer maximum energy efficiency at the lowest costs, making them a popular choice for use in large-scale desalination plants. It is worth noting that SWC5 membranes are available in two different variants: LD and MAX.
Low differential LD Technology® models are an excellent choice for those seeking to minimize colloidal clogging when using conventional pretreatment equipment. These models offer consistently low feed pressures and the longest duration between two successive cleanings.
For those seeking excellent performance with warm water TDS and boron removal, the MAX models are highly recommended. These models have an active membrane surface area of 440 ft2 (40.9 m2), making them a powerful tool for a variety of applications.
SWC6 membranes are an excellent choice for those looking for the lowest feed pressure membranes with low power consumption. These membranes are preferred when the seawater feed temperature is lower, requiring higher feed pressures. SWC6 membranes result in low energy consumption and lower treatment costs, making them a cost-effective solution for desalination. It is worth noting that SWC6 membranes are available in two different variants: LD and MAX.
Low differential LD Technology® models are an excellent choice for those seeking to minimize colloidal clogging when using conventional pretreatment equipment. These models offer consistently low feed pressures and the longest duration between two successive cleanings, resulting in lower maintenance costs and more efficient operation.
For those seeking excellent performance with warm water TDS and boron removal, the MAX models are highly recommended. These models have an active membrane surface area of 440 ft2 (40.9 m2), making them a powerful tool for a variety of applications.
Differences between the WSC series seawater membranes
