Raw Water Pumps & Storage Tank
Process Conditions
• Medium salt water -> highly corrosive
• Sea Water atmosphere -> corrosion outside pipe
system
• Flow rates: 4.800 m³/d – 600.000 m³/d
• Piping inside and outside of buildings -> temperature
peaks and UV-impact on piping
State of the Art equipment
• SS and FRP pipes
• Butterfly Valves with Super Duplex
Discs
+GF+ solution/ advantages
• HDPE – piping systems
• Even large dimensions available/ more flexible onsite than FRP/ saddles reduce
required space and save costs
• Less weight than SS and definitive no corrosion inside & outside
• Even duplex discs of butterfly valves will corrode after some years – plastic ones do
not and we now have the possibility to offer butterfly valves up to d1200

Process goal and special requirements
• Removal of nearly all suspended solids (outlet normally 10-15 ppm conc.),
• Removal of large impurities incl. small crabs, fish, algae ….
• Problems with deposits inside pipes due to pH adaption (precipitation of
carbonates)
• Problems with dosing of several chemicals

Process Water Treatment Plant
Project Description:
Greenfield Process Water plant at the petrochemical site of Leuna /
Germany by WAT Membratec. Water from existing service water
system of the chemical plant is treated in order to achieve demin-
quality for several consumers on site. The process water plant
consists of an UF/RO-system, inclduing required heat exchanger
systems and different chemical dosing units for cleaning in place
(CIP) of the membrane equipment.
WAT Membratec is a medium-sized German EPC-company for any
kind of water treatment plants. WAT is a longterm +GF+ customer
relying on +GF+ quality in order to meet the high requirements
regarding safety and up-time of chemical industry.
