Date:2013-11-20 18:16:12

On the 20th Nov we received our customers from Australia Moulbourne Tony and Angel,who visited the RO water treatment for dental hospital .The output water is at least 10us,aftera long talking in our business we design the whole project for the RO water purification system.

Below is the basic information about this Water treatment purification system.

1T Stainless Steel Reverse Osmosis Water Purifier

Specification of water purifier equipment:

RO Water purifying system uses the American latest Reverse Osmosis device. 

Meanwhile ,this equipment with the preprocessing device, by the high pressure ,

 it enables the water to pass the reverse osmosis film with a diameter of 

one ten-thousandth of a micron and separates impurities, ion, microbes and colloids in the water, 

so as to meet the water requirements in cosmetics ,pharmacy ,electronics and food industries.

Guarantee: for all the machine, it claims one year for guarantee.(Excluded from the warranty are problems due to accidents, misuse , misapplication, storage damage, negligence, or modification to the Equipment or its components. ALSO THE EASY BROKEN SPARE PART IS NOT INCLUDED IN THE GUARANTEE)

Installation: after the machine arrive your factory,if you need,our technician will go to your place to install and test the machine and also training your worker to operating the machine (The time of train depend on you worker). The expenses (air ticket ,food , hotel,the travelling fee on your country) should be on your account and you need paid for the technician USD50 per day. also you can go to our factory to do training.

After service: If you get the problem on the machine ,our technician will go to your place to fixed the machine as soon as possible. The cost should be in your account.(as above).

Annotation: What is the EDI system in the RO system:

Electrodeionization for ultrapure water
Electrodeionization (EDI) is used after reverse osmosis for polishing of demineralized water to obtain low levels of conductivity and silica. The EDI uses ion exchange membranes, ion exchange resins and electricity to produce high-quality water with no regeneration downtime. EDI is an alternative to a conventional mixed bed polisher.

EDI in RO system.jpg
Typical applications for EDI are boiler feedwater at heat and power plants, process water within the electronic industry, the pharmaceutical industry, hospitals and laboratories.
Typical applications of EDI
EDI after RO for low conductivity

Water for power plant
Instead of using a conventional mixed bed, a membrane degasser in combination with EDI can produce high-quality demineralized water without using any chemicals. This provides corrosion-free boiler feedwater with low conductivity and silica content.

Ultrapure process water
EDI after reverse osmosis supplies ultrapure process water with low conductivity. The photo shows EDI for ultrapure water at a microelectronic company. The EDI is customized with special pharma modules for a hygienic design.
EDI making purified water within pharma industries

Water for pharma
Purified water production within pharma industries requires a water treatment system in a hygienic design. The EDI is customized to meet the current versions of European and United States Pharmacopoeia (USP, Ph. Eur.).
