Point-of-use reverse osmosis element design, specifically the distribution of feed water to the membrane, has remained somewhat static since the introduction of thin layer/film composite (TLC) or non-cellulose membranes. Most reverse osmosis systems, depending on design and operating conditions, dispense 70 to 90% of feed water to the drain. Many RO systems use a similar membrane and distribute water through the element in the same manner, so there is little opportunity to increase the system’s efficiency.
Point-of-use (POU) reverse osmosis (RO) membranes often get a bad rap within the water treatment industry for a few reasons: It is a saturated, commoditized market with slimmer margins; there have been minimal technological advancements in system performance; they have a high percentage of wastewater to drinking water; and consumers are demanding greener, less wasteful products.
Changing customer needs lead to shifts in RO technology
The new high-performance GRO’s element design integrates a 100% dry membrane to help maximize its lifespan and provide enhanced performance to the end user. It also has a 50% recovery rate, while maintaining a retrofittable design for easy integration.
Applications for R14 Series RO systems for water purification in commercial settings include municipal water treatment, steam boiler and steam sterilizer make up, laboratory use, spot-free car washes, food processing, and metal plating & finishing, as well as water for humidification. The systems come in compact, wall-mounted version or in floor-mounted systems.
The water sector recognized Abengoa's work and contribution in 2014 at the Global Water Awards
Abengoa was named Water Company of the Year at the Global Water Awards ceremony held in Athens, Greece. This award recognizes the contribution that Abengoa has made to the water sector in 2014 through its projects, research and other initiatives.
The awards committee took into account Abengoa's ability to offer customized solutions for each client, as well as the diversification of its non-desalination assets. The characteristics of the Vista Ridge water transmission project also caught the attention of the committee.
New membrane is available in three different GPD models
Pentair Water Purification unveiled its new reverse osmosis membrane, the GRO, during WQA Aquatech USA last week in Las Vegas. The high-performance GRO boasts a 50% recovery rate while maintaining a retrofit-able design.
NFS is a nanofiltration (NF) membrane formulated to deliver sulfate rejection and flux performance in sulfate removal applications. In addition to exhibiting high mechanical strength and durability, the membrane provides a 30% increase in flux efficiency and more than 99.5% average sulfate rejection when tested under typical seawater operating conditions. This type of NF technology is ideal for enhanced oil recovery during water flooding processes through the prevention of scaling and oil well souring.
The event will take place in the second half of 2017
The International Desalination Assn. (IDA) has selected São Paulo, Brazil as the site for its 2017 World Congress on Desalination and Water Reuse. The event will take place in the second half of 2017; specific dates and details about the venue are currently being finalized.
The announcement follows the conclusion of “Water Reuse and Desalination for Latin American Development,” IDA’s first conference in Latin America, which was held in Rio de Janeiro in March.
Entrants were asked to develop a new design for a central tube connector for the company's spiral-wound reverse osmosis membranes
GE announced the five winners of its latest innovation challenge to develop a new design for a central tube connector for its spiral-wound reverse osmosis (RO) membranes. The company was looking for a unique and original means of connection that eliminated components, reduced cost and improved efficiency, while also expediting the manufacturing process.
