ProMinent Dulcosmose - Model SW - Reverse Osmosis System
From Membrane Technology and Membrane Filtration - Reverse Osmosis Systems
Permeate output 780 – 29,000 l/h. The reverse osmosis system Dulcosmose SW is the standard model for modern desalination of salt water. Equipped with the latest generation of 'high rejection low-pressure' diaphragms, this system achieves maximum permeate output with moderate operating pressures, thereby lowering investment and operating costs.
Product Overview
Salt water is transformed into drinking water.
A reverse osmosis system of type of SW has PVC pipework on the low-pressure side. The high-pressure side of the system has a potable water-compatible, highly corrosion-resistant inner seal due to the high NaCI content. The integrated semi-automatic cleaning system with permeate and/or raw water flushing ensures exceptionally long diaphragm service lives, as scaling and fouling effects are minimised. The system can be adapted with ease to specific customer requirements. Pipework material, other types of diaphragm for enhanced salt retention, integration of measuring and control technology and metering technology to visualisation of the entire process with peripheral components via a PLC. Everything can be selected at random. Optional for all systems: They can be fitted with a system for energy recovery from the concentrate flow. The latest generation of what are known as pressure controllers is used.
Your Benefits
