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...

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 is Alkalinity and should I be worried about it in my Pool or Hot Tub?

With all pools or hot tubs, one of the most important jobs is making sure that your water is regularly tested and safe to use. There are a number of parameters that can be measured including the disinfectant levels (usually chlorine or bromine), pH and alkalinity. What is Alkalinity? Alkalinity, normally referred to as total alkalinity, is the measurement of the alkaline salts (carbonat...

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...

Interchangable water sampler - Telescoop Sampling System

The Telescoop sampling system by Burkle is a environmental and water sampling dipper system that comes in two parts - a telescopic rod and a sampling tool/attachment. This makes it highly versatile with many combinations of rod and attachment. To make up the complete system you need to separately buy a suitable rod and appropriate sampling attachment. Should you need to change either part, then...

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...
