There are several ways to
supply the required capacities of raw water for power generation, seawater
desalination, municipal systems, and for the oil industry. These
utilities have been getting their supply of raw water through open intake
systems. The need has become apparent in the last 20 years to radically
modify these systems in order to comply with stricter environmental regulations
imposed by governments around the world. In Elmosa, we invested heavily
in finding an alternative to open channel intake systems. We conceived
and researched the idea of pre filtration at the water source. We set up
models and conducted model studies in advanced hydraulic labs. We made
a breakthrough in the water intake system technology by developing an infiltration
system. The Infiltration became its brand name.

Why
a Utility Would Like to Install the Infiltration
|
-
Shore Installation.
-
No highly skilled personnel
required for installation.
-
Modular filter systems makes
it easy to transport and install.
-
Infiltration area design flexibility.
-
Expandability without the need
for system shutdown.
-
Minimal or no maintenance:
-
no backwash,
-
no cleaning,
-
no treatment,
-
no scrapping,
-
no replacement or recharging
or rehabilitation.
-
No moving parts, nothing to
rust, tear or wear.
-
Reduction of surface water user
operation and maintenance costs.
-
Absence of metal parts in any
stage of the system making it adequate for reverse osmosis raw water supply.
-
Total exclusion of Zebra Mussels,
fish, fish larvae, seaweed, sand, trash.
-
Continuos supply of clean water
in sufficient quantities to run any system capacity.
-
System performance and flowrates
unaffected by violent breaking of waves on the beach during storms.
-
Oil slick resistance.
-
Takes only few days to install
and commission.
-
Low cost.

Why the Infiltration
is cost effective
|
-
No ongoing operation or maintenance
expenses associated with the system.
-
Costs are largely limited to
initial materials and installation.
-
Initial expenses are estimated
to be 40% to 70% of those of the standard system.
-
Capacities are virtually unlimited.
-
Pre filtered water with low
silt density index (SDI) reduces the pretreatment costs for reverse osmosis
systems:
-
need for coagulation and flocculation
minimized,
-
pretreatment chemical consumption
reduced,
-
residence time is reduced resulting
in smaller and cheaper buffer tanks.
-
Expenses reduction of operation
and maintenance in power plants as a result of the absence of eroding materials,
usually present in raw water supplies.
-
Biological fouling is reduced.
-
Pumping energy is reduced.
-
Low capital investment.
The savings made by the lower
costs of operation and maintenance of reverse osmosis and power plants
are estimated to pay off the initial system costs in a short period of
time after start up.
Why Environmentalists
as well as Engineers and
Operators Love it
|
Because:
-
It utilizes the site resources
for its construction and operation. It employs natural forces for its operation
and maintenance.
-
It preserves the natural conditions
and habitats; best for fragile sites.
-
Simplicity of design, construction,
operation and maintenance.
-
Low cost.
The Infiltration is the ultimate
