In addition to modules, AQUA|STILL also designs pilot systems for easy operational systems, focusing on easy transport, easy start-up, and highly reliable testing. AQUA|STILL uses standardized building blocks to this end. We can quickly and reliably determine the KPIs for your specific processes such as flux and thermal and electrical energy efficiency.
This installation is a pilot system specially designed for continuous operation with aggressive fluids such as acids and brine solutions on site. Remote control and data-logging are standard. The unit consists of three standard-sized pallets which contain the brine circulation loop, the distillate circulation loop, and the core of the unit with membrane modules and several heat exchangers for regeneration, heating, and cooling. The capacity for normal seawater with a temperature range of 20-85 °C results in a distillate production of approximately 200 l/hour
The AQUA|FLEX 100 is a standardized installation which can be used for demonstration purposes at customers’ sites over the course of a few months. This is a flexible unit which can be used for several purposes with heat and cooling on site. Possible applications include the production of distillate water or concentrating beverages and brines. The AQUA|FLEX 100 demonstrates the reliability of the modules over longer periods under daily process conditions. Production capacity for this unit ranges from 200 l/hour up to 1000 l/hour, depending on temperature profiles and fluid properties.
The AQUA|FLEX 150R is an extended version of the AQUA|FLEX 100. Waste heat is recovered using an extra heat exchanger, which results in a more energy-efficient system. This system is designed for medium- to-large-scale applications. Extra modules can be added to enlarge the total capacity of this system.
For large commercial plants we use standard building blocks, the same used for the AQUA|FLEX 100 and AQUA|FLEX 150R units. By placing several units next to each other, this approach provides great flexibility, reliability, and variability in the production capacity for the customer. The system can be installed quickly and expanded to suit customers’ needs. For specialized full-scale industrial configurations, please contact us to discuss the possibilities in detail.
Feed/bleed block an distillate production block
For the feed/bleed block and the distillate production block we use a standardized unit consisting of two tanks; a circulation pump; a discharge pump; the transmitter for flow, temperature, and pressure measurements; and an E-cabinet.
Heat input block and heat removal block
These blocks consist of two levels, whereby the lower level provides or discharges heat by means of a heat exchanger and the upper level holds six membrane modules. Piping trays are integrated on the skid for feed and discharging of the modules.
Heat regeneration block
This block can be added to the above four blocks when there is a need for heat regeneration. An extra heat exchanger regenerates the heat that is lost due to water evaporation in the membrane modules. The heat exchanger is installed on the first level and extra optional membrane modules can be installed on the second level of the pallet.
