A Guide to Basic Sewage Effluent Testing

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. ...

SDI test kits: what are they and how do they work?

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...

Camlab Pool Testing Kits

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...

Laboratory balance use for wastewater analysis

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. Analytical balances for waste water analysis Balances provide quantitative...

How do I measure and calibrate at low level turbidity?

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...

What is Suspended Solids?

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 ...

What filter paper is used to measure silt density index (SDI)?

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...

Using TRUEscience:Redox to monitor disinfection potential of water

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....

Conductivity, Resistivity, TDS and Salinity Measurements

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...

What is the mV mode on my pH meter used for?

[caption id="attachment_2586" align="aligncenter" width="285"] Jenway 370 pH meter[/caption]   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...

How do turbidity meters work? What does ratio and non ratio mean in a turbidity meter?

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.
