High Pressure Pumps for Reverse Osmosis

With Danfoss high-pressure axial piston pumps tailored to Sea Water Reverse osmosis (SWRO) applications you will get one of the most reliable and sustainable pumps for desalination. The APP pumps can be used in almost any SWRO application – land-based, offshore or marine. Mounted in containers or trains, the APP pumps can contain several pumps in parallel to secure uninterrupted and sufficient supply at any time.

High Pressure Pumps for ZLD Applications

When using a Zero Liquid Discharge (ZLD) or Minimal Liquid Discharge (MLD) system for treatment of industrial wastewater, a membrane-based process will help to reduce the energy consumption radically compared to traditional evaporative technologies. Membranes have been developed for pressures up to 120 bar and with Danfoss APP W HC pumps, professionals now also have access to a durable, reliable and high-efficient pump that can withstand the challenging requirements.

Energy Recovery Devices

The iSave is the 3-in-1 Energy Recovery Device (ERD) optimized for sea water reverse osmosis applications. With iSave you get a pressure exchanger, booster pump and motor integrated into one compact unit for high efficiency andlow operational cost. The small footprint of the iSave makes it a popular solution when the space is limited. When fitted with iSave, the Danfoss APP pumps produce more fresh water per square meter than any other system in the market.

​iSave can be used in almost any SWRO application – land-based or marine, new or retrofit. The 3-in-1 design allows fast commissioning, continuous monitoring of performance and easy regulation to accommodate seasonal changes. Other isobaric devices have been known to cause over-spin and over-flushing that lead to poor process control and low efficiency. This is avoided with the active control possibilities offered by the iSave technology.

Pressure transmitters

Danfoss pressure transmitters help keep demanding industrial processes under control. Accurate, robust and buuilt for long life, they perform reliably even in the harshest environments.

​The Danfoss DST P40I is a robust and accurate pressure transmitter designed specifically to meet requirements in corrosive industrial environments – such as desalination systems, sea water cooling, and chemical processing. The transmitter housing is machined from a single titanium rod to eliminate any structural weakness. The pressure-sensing element is made from 96% AI2O3 ceramic with superior chemical immunity. The pressure transmitter uses the piezo resistive principle, and the Wheatstone Bridge is printed directly on the inside of the ceramic diaphragm to ensure fast response time and a high degree of measurement precision.

Variable Frequency Drives

The considerable daily load variation in water or wastewater treatment plants makes it economically feasible to introduce motor control on rotating equipment such as pumps and blowers. The new generation VLT AQUA Drive can realistically offer first-year cost savings of between 10–30% compared to traditional drive solutions. Its high lifetime availability and low energy consumption and maintenance costs provide you with the lowest cost of ownership.
​

​
The VLT® AQUA Drive is designed to provide the highest level of performance of AC-motor-driven water and wastewater applications. Featuring a wide range of powerful standard features, which can be expanded with performance-improving options, the drive is equally suited to both new and retrofit projects.

The quick and user-friendly setup of water and pump settings reduces installation time ensuring a fast route to maximum energy efficiency and motor control. By collecting the most important parameters in one place, the risk of incorrect configuration is reduced significantly.
