Containerized Reverse Osmosis Plant 95,000 GPD for Hot Brackish Water - Niger

Product Description

Application: Hot Water Temperature

Water Challenges: As freshwater supplies shrink and demand increases worldwide, more municipalities and end-users are exploring brackish water desalination as an option to solve water scarcity and secure water supplies.

The temperature of the feed water has an inverse effect on the reverse osmosis membranes performance and flow rates. As water becomes hotter it simultaneously gets thinner and the flow rate produced from the membrane increases. However, this process comes at a cost to the quality of the water which decreases as a result. In order to ascertain the correct membrane permeate rate at a given temperature then you must multiply the rated permeate flow of the RO membrane in the chart above. Your result will be the permeate flow at that temperature.

Pure Aqua, Inc. is widely recognized as a leading manufacturer of high quality custom water treatment systems for many industries that are built to handle fluctuating water temperatures with efficiency. We specialize in the design, manufacturing, commissioning and startup of purified water systems.

Applied Solution: One of Pure Aqua’s projects was for a containerized industrial reverse osmosis system for hot water application. We designed and manufactured the system to handle higher water temperatures than what a standard RO can handle. All the components of the RO were capable of handling temperatures up to 48° Celsius. The system was installed in a 40 foot HC insulated and air-conditioned container that was seaworthy for ocean freight. We used a hybrid membrane design using SWC6-LD with CPA5-LD membranes to achieve higher rejection. The end user requested this design to save on energy costs to cool down the feed water prior to the RO system. The system met all the customer’s requirements in achieving the desired water quality and quantity, as well as energy savings.

System Capacity: 95,000 GPD
