以色列 MSDI2200全自动在线SDI仪测定仪产品的介绍：

什么是SDI值SDI，英文名为Silt Density Index，我们称之为污染指数值，也称为FI(Fouling Index) 值。

SDI值是测量通过直径47mm ，孔径0.45μm 的SDI滤膜的流速的衰减。

SDI值测试中之所以选择孔径0.45 μ m 的滤膜，是因为在这个孔径下，胶体物质比硬颗粒（如泥沙、水垢、铁锈等）更容易堵塞滤膜。

流速的衰减被转换成 1 到 100 之间的数值，即 SDI 值。 SDI 值越低，水对膜的污染阻塞趋势越小。

SDI值是水质指标的重要参数，它表征了水中胶体、灰尘、泥沙、铁锈更颗粒和其他能阻塞各种水纯化设备的物体的含量。

在反渗透水处理过程中，SDI值是检验预处理系统出水是否达到反渗透进水要求的主要手段。

SDI值的大小对反渗透系统运行寿命至关重要。从经济和效率综合考虑，大多数反渗透厂家反渗透进水 SDI 值不高于5.

在水处理设备中，我们通过测定SDI值，可以选定相应的水纯化技术或设备。

根据ASTM D4189-07的规定，测试SDI值这种方式在行业内是的。

1. Introduction

1.1. General Deion

Multi Channel On-Line Quality Water

Analyzer, SDI-2200

he SDI 2200 Automatic, On Line, Silt Density Index

Monitoring System is a unique on-line control system, designed

for continuous, unattended operation in desalination and other

water treatment plants.

The SDI 2200 is used in critical water quality applications, where precise

control is essential for safe and economic operation. It replaces the manual,

error prone, conventional procedure with an automatic, precise and infallible

routine.

The SDI 2200 is a complete self-contained system meant for unattended

operation with extensive reliability and with advanced fault analysis and

warning.

The rugged, spray proof (IP 53) wall mountable system performs all the

below steps that are required for quality water testing results:

ƒ Flushes pipes prior to measurement. ƒ Controls water pressure.

ƒ Measures flow rate.

ƒ Replaces filter.

ƒ Drains the water and cleans the system at th

ƒ Programmability of the measurement protoc

ƒ Monitors executed program.

ƒ Data logging in digital memory.

ƒ Real time SDI and status display. SDI-2200

ƒ Programmable alarm on over-limit levels.

ƒ Self-test and fault conditions alarm.

ƒ Optional dry contact and analog signals for remote control and

monitoring.

The Display panel provides the operator with interface and on-line control to

the Analyzer control functions.

There are four possible input channels for the SDI-2200 driven analyzers

categorized as follows:

ƒ 1 Channel Analyzer: SDI-2201

ƒ 2 Channel Analyzer: SDI-2202

ƒ 3 Channel Analyzer: SDI-2203

ƒ 4 Channel Analyzer: SDI-2204

1.2. Principals of Operation

Standard Test Mode

Silt Density Index (SDI) is measured by comparing the flow rate of a

known quantity of water, where the water quantity is kept under constant

pressure. The flow rate is measured twice, once where the water flows

through a standard filter, as a reference, when the filter is unused, and

the second time after the filter is exposed for 1-15 minutes, and the

water sample flow is kept always under constant pressure.

The drop in flow rate is a direct measure of the silt build-up on the filter.

The flow rate is derived from quantities and timing information:

Where:

initial time required to collect 500 [mL] of sample,

time required to collect 500 [mL] of sample after test time t t: total elapsed flow time, min. (usually Standard Measured Time1

)

The SDI 2200 provides the same type of measurement both in automatic

nd in on-line mode for up to four independent sampling points.

The pressure is kept constant by precisely regulated air pressure applied on

he water surface without the need of any mechanical device.

Auto Time Test Mode

n cases where the silt density index (SDI) reading is unstable and

eadings are higher then 5 (i.e. Plugging Factor is higher then 75%),

during the 15 minutes check time, the Analyzer can be programmed to

work in AUTO TIME TEST MODE d on the following test

method automatically:

ƒ The %P30 (Plugging Factor) calculations will proceed and

recorded in intervals of one-minute elapsed.

ƒ Calculations will stop once %P30 (Plugging Factor) 75% has been

reached.

ƒ New SDI2 readings will be displayed d on the last calculated

plugging factor at the last measured time also check time will be displayed.

All SDI test readings are on 0-100 scale where the exact check

time figure has no valuable meaning as in the Standard Test

Mode. In general, the higher the SDI reading the more silt is in

the water. When the plugging factor after 15 minutes is

calculated to be lower then 75%, the Analyzer will switch and

calculate the test results d on the Standard Method.

%P30 = 100 1 ×

Where:

%P30: plugging factor at 30 [psi] feed pressure,

: initial time required to collect 100 [mL] of sample,

1 Standard Measuring Time (SMT) is 15 minutes. The higher the expected SDI value, the lower

the SMT value. The SMT scale value ranges from 1–15.

2 - if after 15 minutes the readings are lower then 75% results are being calculated as per the

Standard method. The higher the SDI readings the more silt are in the water.
