Find out what the rules are for testing private water supplies for domestic/residential purposes for less than 50 people or, 10m3 / day. This is covered under regulation 10 of the drinking water inspectorate guidelines and highlighted here along with recommended products.
Feedwater are one of the first laboratories in the UK to offer new qPCR rapid legionella testing. With results available in as quick as 6 hours it is possible to get results on the same day the sample arrives in to the lab.
Feedwater can now offer Full BSRIA compliant water analysis for Micro and Chemistry parameters to measure the control levels in your closed heating or cooling system.
If you are having trouble trying to size your closed heating or chilled system, our handy sizing ‘rule of thumb’ may help when calculating chemical inhibitor dosing.
Information obtained from regular monitoring can indicate:
whether or not water replacement and backwashing are being undertaken at sufficient frequency,
disinfectant levels are adequate,
show whether or not the operation of the water treatment plant is coping effectively with the bather load,
highlight any unnecessary hand dosing of water treatment chemicals,
provide information on the condition of the filter bed, and
provide advanced warning of failure of filter, pumps, valves etc.
It is important to test your closed system regularly, especially for chemical reserves, Feedwater offer a range of Chemistry and Microbial tests performed by our in-house Micro and Chemistry labs. We can also provide test kits for you to test your own closed system water for inhibitor reserves and other parameters.
It is common practice to test water for metals, this could be for drinking water reasons, limits on the levels prohibited in waste water or to establish the scale potential of the water. To make the provision of these types of water tests simple, Feedwater has created a number of metals analysis packs which include the sample kit and freepost return to our chemistry laboratory for analysis.
When it comes to protecting your boiler from corrosion there are two aspects you need to look at, first is choosing the right chemical treatment and the second is hotwell/feedwater temperature.
You can buy the chemicals mentioned in this procedure in our web shop by following their links. Before starting ensure that the Descaler is suitable for the system metallurgy. DESCALER ‘SF’ should NOT be used on stainless steel, aluminium or galvanised surfaces. [table id=descalers /] Set up a circulation around the heat exchanger using an…
L8 is the Health and Safety Executive document that gives recommendations for the control of Legionnaire’s Disease. It recommends that domestic water tanks are inspected annually and if found to be dirty should be cleaned and then disinfected.
