| The
wedgewire products are manufactured by rolling a V-Shape wire
around an internal framework of longitudinal bars. The external
V-Shape wire can have either a sharp end, in what is known as
Vee-Wire Sharp, or it can have a round end in what is known
as a Vee-Wire Wear. The wire and the bars are made of carbon
steel, carbon steel galvanized, stainless steel, copper or any
alloy and they are joint using resistance welding.

| The
continuous slot wedgewire products are used in a wide variety
of industries, such as, construction of water wells, drainage
wells, breweries-malting industries, water and wastewater, treatment,
as intakes for dams, rivers and lakes, different mining process
(clarification, dewatering, and selection process), food industry
and in many other processes and industries. Even though it wedgewire
products have multiple uses, this product was originally developed
in the United States in order to solve the problems associated
with water wells built in fine and very fine uniform sands formations.

Depending
on the type of wire used and the slot opening, the open
area of a wedgewire screen can vary between 10% and 70%
of the total area (see graph). The average opening area
of a water well screen varies from 35% to 45% compared
with 5% to 15% on average of a other scrrens (e.g. perforated
or bridge screen). In the case of support grids, the filtering
area can be up to a 70% of total area, depending on the
material used and the slot.
The continuos slot water screen has several advantages
compared to other screens such as bridge slot screen or
perforated screen A larger opening (filtering) area of
a wedgewire screen leads to superior performance of a
water well compared against the installation of other
types of screens. Moreover a wedgewire filter for water
well are self-cleaning (go-no go), thus, prevents losses
due to friction as well as losses associated with pumping
sand. Also, a continuous slot wedgewire water well screen
eliminate the problems associated with fine sands, thus,
increasing the life of the pumping equipment.

Benefits
of continuos slot wedgewire screens are many, among some of
those are:
- Continuos
slot screen offers a larger opening (filtering) area, which
lead to a larger production of the water well. This fact,
implies a reduction of the long-term average cost of the
system.
- A
greater opening area (filtering area) reduces the pressure
in the systems and head loss, and therefore reduces energy
consumption.
- Minimal
water frictional head loss which lead to an increase in
the efficiency of the water well and/or filtering systems.
- Elimination
(reduction) of the problems associated with pumping of fine
sands in water wells. Longer useful life of the system,
which reduces the cost of capital and operational cost in
the long run.
- In
the case of water screens, these are self-cleaning, which
leads to a reduction of the maintenance cost and longer
life of pumping equipment.
- Stainless
steel or galvanized wedgewire screens offer a greater resistance
to accelerated corrosion.
- Minimum
failure risk in the construction process especially in wells
built in thin aquifers.
- Failure
risk reduction of the filtering system.
- Products
design can be esaily adapted to any specific project at
a minimun cost
