Silt Density Index Monitors EZ SDI-4, EZ SDI-1D, EZSDI-1C

The EZ SDI-4™ Automated Silt Density Index Test System is designed to perform a standard Silt Density Index Test according to the ASTM D4189-95. The EZ SDI-4™ will perform four separate tests before filter replacement is necessary. Information is displayed on a back-lit liquid crystal display, and on individual light-emitting diodes ( LED) . Functions and controls are operated through switches on the membrane keypad. The EZ SDI-4TM incorporates the following features: One Temperature sensor to measure temperature change during test. One Pressure sensor to ensure proper filter feed pressure. Two Alarm Outputs; one for high or low filter feed pressure, and one for high SDI.

Silt Density Index Monitors EZ SDI-1 The RODI Systems EZ SDI™ automatically and consistently monitors the silt density index of RO feed water. Operators can quickly and regularly check the effectiveness of the RO pretreatment system without bothering with labor-intensive manual tests. The EZ SDI™ is microprocessor controlled and fully automatic. The monitor is housed in a NEMA 4X enclosure and is designed for permanent installation in industrial environments. The filter holder allows the use of standard 25mm test filters available from a number of suppliers. Replacing the media is a two-minute process and the test is initiated with the press of a button. The EZ SDI™ uses the same testing method as specified in ASTM D 4189-95. This standard method indicates the quantity of particulate matter in water and is applicable to relatively low ( less than 1.0 NTU) turbidity waters such as well water, filtered water, or clarified effluent samples. Since the size, shape, and nature of particulates may vary, this test method is not an absolute measurement of the quantity of particulate in a particular water source. Maximum SDI values of RO feed water are commonly specified by RO membrane manufacturers, and demonstrating adherence to these SDI specifications may be necessary to receive guaranteed performance from the membrane supplier. Continuous Sample Flow - The EZ SDI™ is designed for permanent installation. In order to prevent stagnant conditions in the sample line, the monitor continuously allows a side stream of sample to flow through the monitor up to the point where the sample enters the filter. A specially designed orifice controls the rate of this side-stream flow. The orientation of the flow control orifice also allows air in the sample line to be separated from the sample before the sample enters the filter holder.
