Lovibond's new TB 350 Turbidity Meter

Turbidity is a measurement of suspended particles in water that scatter or absorb light. For example, the more suspended solids there are, the murkier the water will appear and the higher the turbidity is. Turbidity will also depend on the size of the particles, as this will affect the scattering or absorption of light. Lovibond turbidity standards for TB 350 IR Why measure turbidity? ...

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...

DPD tablets

DPD tablets (diethyl-p-phenylenediamine) are used to determine chlorine in water and can also be used to test bromine, iodine and other disinfectants. These tablets come in four different types and are used alone or in combination, depending on your measurement parameter. The convenience of using a rapid version is that it dissolves quickly but is used as a visual test only. Image of DPD ta...

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...

Measuring high levels of free chlorine in water

Measuring high levels of free chlorine can be problematic; Colorimeters used to test free chlorine are based on a colour change test; The DPD 1 (N,N-diethyl-p-phenylenediamine) method for residual chlorine was first introduced by Palin in 1957. Over the years it has become the most widely used method for determining free chlorine in water and wastewater. Hach introduced its first Chlorine te...

What's the difference between Phosphate tests for Orthophosphate, Total Phosphorous, Acid Hydrolyzable Phosphates and Organic Phosphates?

Phosphate tests are often stated as reporting Orthophosphate or Total Phosphorous, but can also give other parameters like Acid Hydrolyzable Phosphates. We've taken a look at the definitions behind these terms, so you can tell which Phosphorous or Phosphate test to use. What are Phosphates and Phosphorous? The element Phosphorous, P, exists in water courses in a wide range of forms...
