REVERSE OSMOSIS INSTALLATION AND OPERATION MANUAL R24-SERIES >

IMPORTANT Do not use where the water is microbiologically unsafe. Always turn off the unit, shut off the feed water, and disconnect the electrical power when working on the unit. Never allow the pump to run dry. Never start the pump with the reject valve closed. Please read the entire manual before proceeding with the installation and startup: Never allow the unit to freeze or operate with a feed water temperature above 100 F. NOTES Changes in operating variables are beyond the control Alamo Water Refiners, Inc. The end user is responsible for the safe operation of this equipment. The suitability...

Internal flows across the membrane surface must be high enough to prevent settling of fine suspended solids on the membrane surface. I. INTRODUCTION The separation of dissolved solids and water using RO membranes is a pressure driven temperature dependent process. The membrane material is designed to be as permeable to water as possible while maintaining the ability to reject dissolved solids. The main system design parameters require the following: The concentration of each dissolved ionic species must not exceed the limits of solubility anywhere in the system. Pre-treatment must be sufficient...

R24-08 R24-10 R24-12 Maximum Productivity > (Gallons per day / Gallons per minute) Maximum production based on standard membranes and feed water of 25C, SDI < 3, 1000 ppm TDS, and pH 8. Individual membrane productivity may vary (б 15%). May be operated on other feed waters with reduced capacity. 14,400 / 10 18,000 / 12.5 21,600 / 15 Quality > (Typical Membrane Percent Rejection) Based on membrane manufactures specifications, overall system percent rejection may be less. 98 % 98 % 98 % Recovery (without reject recirculation) Recovery (with reject recirculation, depending on feed water) 59 % 75...

C. PRETREATMENT The RO feed water must be pretreated in order to prevent membrane damage and/or fouling. Proper pretreatment is essential for reliable operation of any RO system. Pretreatment requirements vary depending on the nature of the feed water. Pretreatment equipment is sold seperatly. The most common forms of pretreatment are described below. Media Filter B. RO OVERVIEW Reverse osmosis systems utilize semipermeable membrane elements to separate the feed water into two streams. The pressurized feed water is separated into purified (product) water and concentrate (reject) water. The impurities...

recommended. Iron & Manganese - These foulants should be removed to less than 0.1 ppm. Special media filters and/or chemical treatment is commonly used. pH - The pH is often lowered to reduce the scaling potential. Silica : Reported on the analysis as SiO2. Silica forms a coating on membrane surfaces when the concentration exceeds its solubility. Additionally, the solubility is highly pH and temperature dependent. Silica fouling can be prevented with chemical injection and/or reducing the recovery. II. CONTROLS, INDICATORS, and COMPONENTS (see figure 1) B. Reject Control Valve - Controls the...

III. OPERATION A. INSTALLATION 1. The water supply should be sufficient to provide a minimum of 20 psig pressure at the design feed flow. 2. Proper pretreatment must be determined and installed prior to the RO system. 3. A fused high voltage disconnect switch located within 10 feet of the unit is recommended. This disconnect is not provided with the RO system. 4. Responsibility for meeting local electrical and plumbing codes lies with the owner / operator. 5. Install indoors in an area protected from freezing. Space allowances for the removal of the membranes from the pressure vessels should...

4. Do not apply power to the RO unit at this time. D. STARTUP 1. Verify that the pretreatment equipment is installed and working properly. Verify that no free chlorine is present in the feed water. 2. Verify that the on/off switch is in the off position. 3. Verify that the pump discharge valve (Figure # 1 item C) is open. 4. Install a 20" five micron filter cartridge in the prefilter housing. (Figure #1 item I) 5. Open the reject control valve completely (Figure # 1 item B) by turning it counterclockwise. Close the reject recycle control valve completely if the reject recycle option is included....

Two controller options are available. Controller option # 1 is a basic controller with an on / off switch, low pressure, tank level, and pretreatment interlock (see figure # 2). Automatic low pressure reset If the unit shuts down due to low pressure, a red light on the front of the controller will illuminate. The controller will automatically restart the unit after a user selected time delay. The user selects the delay time by positioning a jumper cap inside the controller (see attached drawing). Tank Level / Pretreatment Indicator If the unit shuts down due to a high product tank level or pretreatment...

Controller option # 2 is the CI 1000. This is a microprocessor based controller with a product water conductivity meter. A separate manual for this controller begins on the next page. The autoflush option is available with both controllers. On controllers # 1, the flush valve is preset to open for 2 minutes every time the pump starts and 2 minutes every hour. On controller #2, the flush times are user programmable. (See the following CI1000 information.) >
