1. System Description AXEON

Water Technologies proposes to provide a reverse osmosis membrane system capable of providing up to

6.9 gallons per minute. The system design shall be based on a feed supply of < 35,000 TDS, with an SDI of < 3 over

an operating temperature of 77F. The reverse osmosis system provided shall be of robust construction and designed to conservative standards for versatility in the event of feed water quality and temperature variations. The system design has incorporated a 5% allowable fouling or flux decline for the membranes without loss of system product water capacity. The RO unit provided will include the appropriate high pressure feed pump, FRP pressure vessels, spiral wound thin film composite RO membranes, Schedule 80 PVC low pressure feed piping, and high pressure piping fabricated of stainless steel. The RO unit will be provided skid mounted, pre-assembled, pre-wired and shall have been fully operationally tested at the factory prior to shipment. The RO system supplied will include Microprocessor based controls and shall be capable of automatic operation with minimal operator intervention. Safety devices shall be provided to protect the RO system and its components from common fault conditions. RO Process Description As water pressure builds in the RO high pressure feed pump suction line, a pressure switch senses the line pressure of the water entering the pump. This switch activates a timer which delays further start sequences until all water lines and pressure vessels reach normal start-up pressures. At the end of the time delay, a start control signal is sent to the RO high pressure feed pump starter. The RO high pressure feed pump then starts and supplies the necessary feed water pressure to the membrane array. The RO feed water is split into two streams, permeate or purified water and concentrate or reject water. The RO permeate flows to the permeate water storage tank. The concentrate is disposed of in accordance with local environmental regulations. When the permeate storage tank is full, the level switch sends the shutdown signal to the RO control panel and the system then begins its post-feed flush cycle which significantly reduces concentrated contaminants from the system. Once complete, the system waits for the next start signal.

2. Components

2.1 Reverse Osmosis Membranes

Filmtec 8” SW30HRLE-400 spiral wound thin-film composite membranes were chosen for this application. Filmtec

8” SW30HRLE-400 spiral wound membranes are the optimum choice for most industrial water applications.

Design Flux rate (the ratio of water produced per ft² area of membrane) is 12.5 GFD.

This low flux rate helps to insure optimum performance and longevity for the

system with ample allowance for normal membrane fouling. These spiral

membranes are less susceptible to fouling from colloidal and scale solids and are much easier to clean than the

hollow-fiber types. The materials of construction are not subject to bacterial attack or hydrolysis at high or low pH.

Filmtec 8” SW30HRLE-400 membranes offer a higher productivity and less compaction, as well as a better salt

rejection with lower applied pressure.
