WATER TREATMENT MACHINES
AQUA WTU
Compact water treatment system for safe dialysis operation
The Aqua WTU is a complete reverse osmosis water treatment system designed to operate in either a direct feed format, supplying up to 5 dialysis machines, or with a treated water tank for alternative applications. The complete system is housed within a compact sound proofed frame providing quiet operation and portability.
Microbiological purity
- The semi-automatic volume controlled chemical disinfection, provides accuracy, security and safety during the disinfection cycle.
- The microbiological purity of the permeate is maintained during standby periods, with the auto rinse program.
- The UV light inside the feed water tank provides additional protection against microbiological growth.
Safety in dialysis operation
- The unit is controlled by a microprocessor which provides a user friendly interface for both manual and automatic operation.
- The continuous online monitoring provides additional patient security and operating efficiencies.
Economical operation
- The programmable auto start / stop and standby functions enable efficient use of water, energy and consumables.
- The ability to supply up to 5 dialysis machines from a single all-in-one unit, reduces capital investment.
- The AquaWTU is quick and easy to install reducing on-site installation costs.

AQUA B
Central Reverse Osmosis Water Treatment System for Safe Dialysis Operation
The Aqua B is a single pass reverse osmosis unit designed to meet the recommendations set down by AAMI, the European Pharmacopoeia and the European Best Practice Guidelines for Haemodialysis (part 1).
Microbiological purity
An integrated aseptic sample point in the permeate return line allows easy and accurate microbiological sampling.
Semi-automatic volume controlled chemical disinfection provides accuracy, security and safety during the disinfection cycle.
Safety in dialysis operation
Economical operation
Aqua B includes the patented Fresenius “dynamic” water saving device providing a considerable reduction in water usage and subsequent cost savings.
A fully programmable control with a 7-day calendar clock provides automated flexible operations. It includes options for automatic start/stop, “stand-by” and “auto-rinse” functions.
The modular design allows for future expansion whilst avoiding large expenditure for replacement equipment.
