Compact pure water solution with up to 90% permeate yield

Project requirements

Production required a solution that could generate cleaning water from tap water in a resource-efficient manner whilst meeting stringent hygiene standards. At the same time, the installation situation was challenging, as the customer had limited space available. The requirement was therefore for a particularly compact, high-performance customised system tailored to the process, offering high yield and cost-effective operation.

Herco solution

The result was a tailor-made, two-stage specialised plant with two lines operating in alternation. In the first stage of each plant, a reverse osmosis system with a capacity of 50,000 l/h operates, whilst in the second stage, a nanofiltration system for concentrate treatment with a capacity of 12,500 l/h is in operation. This results in high yields, reduced water consumption and cost-effective operation, even with a compact plant layout.

Plant engineering

The solution combines high-performance membrane technology with a hygienic design, a compact build and practical enhancements to ensure safe, efficient plant operation.
