Chlorine resistant liner developed for water storing

Together with leading raw material producers and processors, NPI has developed a new type of liner material specifically suitable for the storage of clean water with higher doses of chlorine. This material combines good mechanical strength and UV resistance with a Cl absorption of 250 ppm. "This is 10 times more than the usual current liners used for storing irrigation water", says Arjen van Dijk, director of water storage. 

"Despite the fact that the use of chlorine is not desired in the horticulture sector, chlorine is still commonly used in irrigation systems, avoiding contamination and bacteria growth in these systems," says Arjen. "Due to the aggressive and unpredictable nature of chlorine, it is hard to always use the correct levels of chlorine in water storage. For instance, every increase of 10 °C of the water can double the activity of chlorine."

Especially when the water is already clean, chlorine searches for substances to react with. Most of the time, this is the tank liner. "ENPEX CPL (Chlorine, Potable water liner) combines good mechanical strength and UV resistance with a CL resistance and is suitable for food and contact with clean potable water," Arjen adds.  

NPI delivers the ENPEX CPL as a standard in 0,75 mm and 1,00 mm. "We can also supply 0,60 mm on project base." The NPI is highly certified in manufacturing water storage systems and processing the ENPEX CPL. NPI is able to provide supervision and training for its customers worldwide to make correct installations and/or process the liner at the location when necessary.

"Together with our high-grade water tanks and our steel roofs, we provide an optimal and durable solution for the storage and protection of your clean water," Arjen concludes.

NPI is present at GreenTech in stand 01.462 in hall 1.
