Marking dyes of the Pure series
Natural food-grade dyes
Showing your colours in an eco-friendly way – pure and simple
The 100 % biodegradable dyes of the Pure series are easily visible without technical aids and ideally suited for the direct inspection of the pipe run or connections when detecting faulty or leaking connections as well as incorrect discharge conduits of drainage systems.
Depending on the desired colour intensity, these rich marking dyes can be mixed with water as needed, for owing to their environmental compatibility the Pure powder blends have no maximum dosage limits.
Further possible applications can be found in the field of tracer hydrology, e.g. for verifying the flow path, visualising the mixing and run-off characteristics in flowing waters, lakes, dams or water treatment plants as well as for checking the flow rate in fish ladders.
Pure dyes are also ideal auxiliary means for HAZMAT simulations during fire brigade training exercises.
Application example: Checking the connections of separate sewer networks
While in historically grown town centres and old housing complexes with a high level of soil sealing you still often find predominantly combined sewer systems with a common drain, new residential areas are usually equipped with separate sewer networks, which will continue to spread over time – also due to changed water resources laws.
In case of installations on separate sewer systems there are quite frequently faulty connections which can be detected quickly and easily by means of Pure dyes. Just flood the dyed water solution into the drain to be examined and check the route via the inspection chamber.
Dosage can be adjusted as needed
Because of the 100 % natural food-grade ingredients dyes of the Pure series can be dosed to meet every demand – overdosing is not possible.
Depending on the desired intensity 1 to 5 litres of water can be added to 2 g of Pure dye so as to produce between 100 and 500 litres of dye solution with only one plastic jar of Pure dye.
