MEMSTILL® for closing water cycles in greenhouse horticulture · Jurgens R.M., TNO Feenstra L.,...

The aim of the project is to identify and demonstrate technologies that are: - robust and reliable - able to handle a varying water composition - have no need for extensive pretreatment - able to cope with fouling components - available on short term. A feasibility study performed by TNO and WUR showed that for water cycle closure in the greenhouse horticulture both reversed osmosis (RO) and Memstill ® membrane distillation (MD) offer promising perspectives. Memstill ® has advantages in utilising waste heat from the greenhouses (fig.3). All technologies have been researched on lab-scale (fig. 4). From november 2011 to june 2012 Memstill ® and RO are demonstrated at pilot scale (fig 2., app. 1 m 3 /h) at Olij Roses (De Kwakel, Aalsmeer, NL). The focus during the study (fig. 5): 1. Recovery of water and retention of the various components; 2. Fouling behaviour; 3. Influence of the components present (nutrients, pesticides, salt) on performance ; 4. Technical and economical evaluation. First results of the Memstill ® pilot: - Quality destillate: suitable for irrigation; - Water recovery of > 85% of drain; - Fouling (scaling) is an issue. The project will be completed by setting up a business case together with all stakeholders (institutes, greenhouse horticulture companies, OEMs and water boards) to aid the implementation of the technology.
