AWT’s desalination equipment is created based on a user-friendly design concept.
Based on the customers’ needs, we have made our equipment easy to
maintain and corrosion-free –proving that this equipment can be used by anyone.

Our efforts for enabling safe use AWT’s design target is that equipment is easy to operate and has superior cost performance. From the design stage, we stick to our concept that equipment needs to be established with a simple structure, where maintenance management can be implemented by anyone. We have also made various creative efforts for reducing work burden significantly, such as producing equipment suitable for transport by container by using unit-oriented structures. We have also enabled the equipment to be operated without chemical dosing so that running costs can be reduced even more.

What is the non-chemical dosing method?
A method of operating seawater desalination equipment without feeding any chemicals. Due to this method, maintenance management does not have to be implemented by an engineer. The equipment will not incur any costs for injecting chemicals or any maintenance activity, and can be therefore operated at low cost. Chemical dosing methods are often used for the purpose of scale prevention and for preventing organic substances from growing, but since they use massive volumes of chemicals in general, they tend to require substantial costs.

Operational monitoring can be implemented from a remote location (optional)

You can control equipment operation by capturing daily operational data into your PC. You can also monitor the data from a remote location by using the internet, where alarm e-mails will be sent to a specified mobile phone when a failure occurs.

Efforts made to allow safe use of equipment Corrosion is a major problem for water treatment equipment. Even stainless steel pipes are not corrosion-free when it comes to treating highly concentrated water. Water leakage is a serious problem for high-pressure operation. When high-pressure water gets leaked due to corrosion, 5.0 MPa high-pressure water would blast out from the pipe (fire-extinguishing water pressure - approx. 0.8 MPa; automobile tire pressure - approx. 0.3 MPa). Replacing expensive stainless-steel pipes once every half a year, leads to expensive running costs. Additionally, equipment has to be stopped during the replacement works, which would suspend water production and become a significant problem. AWT has solved these problems by using resin-coated pipes to prevent corrosion.
