When it comes to sewage treatment, effluent testing is crucial in ensuring the quality of discharged wastewater. By performing regular tests, you can monitor the effectiveness of your sewage treatment process and ensure compliance with effluent standards. This blog will cover an overview of the importance of effluent testing, the methods involved, and the standards governing sewage effluent.

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
In...
Water testing is important when maintaining a pool or hot tub to make sure the water is safe to be in. The water can end up having too many or too little chemicals in it which can affect the pools hygiene and bacteria levels. The most frequently tested parameters are pH, chlorine (free and total), bromine, alkalinity and calcium hardness. Camlab have created water testing kits for testing thes...
There are many ways to work with water to gain information about a selected sample, with a lot of options for equipment. Laboratory balances can be a great option to measure different properties with many different methods possible. To view our range of balances suitable for waste water analysis, click here.

Balances provide quantitative...
Turbidity is a measure of the cloudiness of water and is used as a key water quality indicator. This can then be used to quantify the amount of particles disrupting light passing through a liquid. For example, muddy water has a lot of small soil particles. This disrupts light going through it and makes it very cloudy and turbid. However spring water tends not to have many particles in and so is...

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 ...
Silt Density Index (SDI) is a test used to determine the levels of colloidal and particulate suspended solids in the feedwater to reverse osmosis (RO) systems. This in turn will enable you to estimate the fouling potential. This measurement is of importance as it can be used to predict the lifetime of the RO membrane. This can help save time and money. It is measured following the test...
Oxidation reduction potential (ORP) otherwise known as a REDOX potential measures an aqueous system’s capacity to either release or accept electrons from chemical reactions. When a system tends to accept electrons it is an oxidizing system. Conversely, when it tends to release electrons, it is a reducing system. Like pH, it is not a measure of a concentration directly, but of an activity level....
What is conductivity? Conductivity is a measure of the ability of a substance to conduct an electrical flow through it. In water, many compounds and molecules (such as dissolved salts and inorganic materials) dissociate into constitutive ions. Ions are small sub-atomic particles and carry with them an electrical charge; either positive (cations) or negative (anions). These particles help condu...
Palintest have announced that the ChloroSense, ChlordioXense, ChlordioX Plus, ChloroSense HR and PAASense units have been discontinued and have been replaced by the Kemio. The Kemio is a multi-parameter next generation instrument capable of measuring chlorine (free and total), chlorine dioxide, chlorite and peracetic acid (PAA) in water. You can read our post on the feature of the Kemio here.Â

Many pH meters also have a separate reading range which gives results in mV. This can be used for a range of applications.
1.) Checking your pH electrode calibration. Most meters automate the calibration of pH which makes it simple to perform and ensures consistency in results. However, when issues ar...
Turbidity meters are used to quickly measure the turbidity (or cloudiness) of water, caused by suspended solid particles.
Understanding how turbidity meters work can help in achieving more accurate results and ensuring the samples and meter are handled correctly.

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...
