What is SDI?
Silt Density Index (SDI) is a measure to assess the fouling in water purification systems from Suspended solids and colloidal materials. When it comes to reverse osmosis membranes, suspended solids within the water can cause problems. Then these levels get high, it can cause fouling of the membrane. This will lead to:
Increased cost for maintenance
Reduced lifetime

What is Suspended Solids?
[caption id="attachment_2055" align="alignleft" width="313"] Suspended solids[/caption]
Suspended solids refers to small solid particles which remain in suspension in water. It is used as one indicator of water quality, typically for wastewater applications and is used as part of the Charging system for trade effluent in the UK using the Mogden formula.
It is ...
Suspended solids tests are conducted as a water purity indicator, and to form part of discharge consent. The gravimetric method of suspended solids testing requires filter papers to be used, but these must be of the correct grade to ensure correct results.
We've taken a look at which filter paper grades are approved for suspended solids tests.
Which filter paper should I u...
The measurement of Suspended Solids is often required for discharge consent, and values may be reported to the Environment Agency (EA). [caption id="attachment_8215" align="aligncenter" width="200"] Suspended solids give water a cloudy appearance[/caption] There are several methods for testing the suspended solids present in a water sample, here we discuss the differences between the differen...
Thanks for sharing such a great information.. It really helpful to me.. I always search to read the quality content and finally i found this in you post. keep it up!
I came across your article about "DPD Tablets" on Camlab Info, and it's a valuable resource for anyone seeking information about water testing and analysis using DPD tablets. Your explanation of their usage and significance in water quality monitoring is quite informative.
This article on nanocolor tube tests is a gem for analytical enthusiasts. The idea of zero calibration is intriguing, and your detailed explanation makes it accessible. The step-by-step process helps demystify the technique for beginners like me. The use cases you've highlighted, particularly in...
Grant have introduced the new Controlled Rate Freeze Thaw (CRFT), which is a liquid nitrogen and cryogen free controlled rate freeze and thaw system for cryopreservation in a wide range of applications. Cryopreservation is a process where biological materials such as cells, tissues...
A dipslide is a means of testing the microbial content of liquids. This is a common method of monitoring and measuring microbial activity within many systems and commonly cooling systems. Usually the use of a dipslide is the first line of defence for the testing of microbial issues that could be...
Purchasing items using donated funds without the burden of VAT will now save many Millions of pounds each year which can be put to better use in advancing scientific knowledge to provide new treatments and cures that will shape the medicines of the future.
Working with pressure/vacuum conditions in the lab is common but not all products are designed to withstand this. Products with appropriate geometry and wall thickness are suitable for working safely with pressure. For example, filtering flasks, desiccators, or flat flange vessels, as well as...
