4. MySpring Profile (1)
MySpring - Drinking Water Treatment Systems,
Reverse Osmosis Desalination Units
• Drinking Water Treatment Systems.
• Brackish Water Reverse Osmosis (BWRO)
Desalination Units.
• Consulting, Design, Manufacturing,
Sales (Wholesale, Retail), Installations.

5. MySpring Profile (2)
• MySpring imports components and consumables (RO membranes,
cartridge filters, bag-filters, resin filters, sand filters, HP pumps,
control instruments, chemicals, metering pumps, pressure tanks,
UltraViolet Lamps) from well-known suppliers all over the world (e.g.
FilmTec Membranes, Philips UV Lamps, Grundfos Pumps).
• Keeping big stock of a variety of component codes allows the
company to design and assemble many types of domestic and
commercial, compact, Reverse Osmosis Desalination Units.
• The production line is customized. There is a tailor-made R&D,
technical study and system simulation for each project. The
company designs each system according to the water
characteristics and the daily water quantity requirements of the
client.

6. MySpring Profile (3)
• Each time, the company's engineers prepare an
individual technical study in order to face raw water's
(municipal supply or private well-water) problems
(hard/brackish water, heavy metals, chromium VI,
arsenic, lead, zinc, mercury, high iron/manganese,
nitrate, high chlorine, microbiological load etc.) and
design a system that will produce safe, healthy and tasty
permeate water (from both chemical and microbiological
aspects).
• The final quality of the water can be adjusted by the user
according to his needs. That's why there are a lot of
control instruments on each RO machine. So, the use
and maintenance of the unit is very friendly and easy for
the owner.

7. MySpring Profile (4)

• Mechanical Engineer specialized in Water
Quality &Treatment and RO Desalination,
• Civil Engineer specialized in the Management
and Cleaning of Aquatic Resources,
• Chemist specialized in Water Chemical Analysis,
• Electronic Engineer specialized in Automation.

8. MySpring Profile (5)
• Headquarters: 9, Miliaraki Street,
Kato Patissia, Athens, Attica, Greece
• Website: http://www.myspring.gr
• Industry: Mechanical or Industrial
Engineering
• Type: Privately Held
• Company Size: 1-10 employees
• Founded: 2007

9. MySpring Projects
• Small-Scale Private Brackish Water Reverse
Osmosis Desalination Plants
• Usual clients: Private sector (houses, villas,
hotels, café-bars, restaurants, labs, dentists,
car wash, laundries, distilleries, food
industries etc.)
• Systems capacity: 1-30 m3/24h (Usually 1-12)

10. Typical Project Procedure (1)
First contact with clients via:
• our national agent network (this network has
been established, trained, maintained,
expanded by my face-to-face discussions with
dealers and technicians all over Greece)
• participation in exhibitions
• company website

11. Typical Project Procedure (2a)
• Specifications Definition:
We discuss (face-to-face or telephone or e-
mail discussion) with the client to understand
the specifications and the constraints of the
project.

12. Typical Project Procedure (2b)
The specifications include:
• the kind/type of the raw water that is going to be
treated (municipal network, private well, tank truck
water etc.).
• the average water quantity demands.
• the target quality of the product (treated) water.
• what the product water will be used for (potable,
irrigation, lab use, industrial use, ice maker, coffee
maker, laundry, dish washer, heater, boiler, bathing,
cooking, steam oven, car wash etc.).

13. Typical Project Procedure (3)
• On-Site inspection of the client’s facilities.
• Chemical analysis of the raw water (in some
cases there is microbiological analysis too).
• Initial estimation of the final cost.

14. Typical Project Procedure (4)
• Technical study preparation according to the
results of the chemical analysis.
• Analysis of the needed water treatment and
the needed equipment to compose the final
water treatment system.
• Technical specifications report.

15. Typical Project Procedure (5)
• Design and Simulation of the system.
• Project plan including financial and technical
aspects and timeline delivery. End feasibility
analysis.
• Proposal of the bid.

16. Typical Project Procedure (6)
• Purchase of the needed components from
different suppliers (some basic components
are always in stock).
• Manufacturing of the central water treatment
machine (reverse osmosis device) and
assembling of the total water treatment
system (tanks, pumps, pretreatment and post-
treatment equipment).

17. Typical Project Procedure (7)
• Testing of the system operation at our
facilities.
• Installation of the system at the client’s
facilities.
• Adjustments (flows, pressures, etc.) and
training of the client so that he is able to
handle the system on his own.

18. Typical Project Procedure (8)
• Quality test at the end of the installation to
verify that the whole system is working
properly. Chemical analysis and evaluation of
the final product water (in some cases there is
microbiological analysis too).
