The world's water consumption rate is doubling every 20 years, outpacing by two times the rate of population growth. It is projected that by the year 2025 water demand will exceed supply by 56%, due to persistent regional droughts, shifting of the population to urban coastal cities, and water needed for industrial growth. The supply of fresh water is on the decrease. Water demand for food, industry and people is on the rise.
Lack of fresh water reduces economic development and lowers living standards. Clearly, there is a critical worldwide need to better manage this increasingly valuable resource.
Desalination systems from GE Water & Process Technologies can make abundant fresh water both from seawater and from challenging brackish sources.

PACT principals are among the pioneers in the water desalination industry. Since the early 70s PACT principals have designed and built scores of water desalination plants both for industrial and municipal applications. Among the various desalination processes such as MSF, VC, MED . (thermal processes) and Reverse Osmosis, the latter is the desalination process where PACT has made its mark among the leaders in the field
PACT desalination plants treat brackish and high brackish well-water sources as well as seawater sources ranging from 30,000-45,000 mg/l TDS. Standard capacities manufactured by PACT cover few cubic meters per day up to 1000 m 3 /day. Custom-built systems up to the tens of thousand of m 3 /day are designed in-house and built to the most stringent specifications. Making use of high grade SS alloys for protection against aggressive marine environment as well as state-of-the-art energy recovery equipment for the most efficient use of energy (energy is the single most expensive item in cost of water desalination).

These units are incorporated into larger water purification systems. They will be specified with additional items such as pre-treatment, storage tanks and pipework, dependent on the exact needs of the customer.
Prestige Descale:
A compact RO unit with integrated pre-filtration that accommodates a higher level of output. The Prestige Descale is combined with pre-treatment and storage tanks as appropriate to the needs of the customer.
- Water quality output: please see the attached specification.
- Flow rates: up to 430 litres/hour (at 25ºC)
Prestige Satellite (for Renal Dialysis):
A reverse osmosis unit specifically designed for renal applications, this product will provide a constant, high quality supply of pure water for 4 - 6 renal dialysis machines, depending on the dialysis setup and machine type.
Elite Plus:
These RO units are specifically designed for a diverse range of process applications. They offer a maximum pure water recovery capability of 75% and minimum salt rejection of 97% . A wide range of models offer flow rates from 17 litres/hour to beyond 16,000 litres/hour.
Elite Premier:
Designed specifically for renal dialysis, the Elite Premier offers flow rates up to 2,500 litres/hour, simultaneously supplying up to 40 dialysis machines. It is available in single or double pass versions and offers the option of heat disinfection of the entire system, including the membranes and ring main.

The Deoxygenation system for injection water, can be delivered in two different versions; Minox DeOx System - 2 Stages, or Minox Deox System - Compact Tower.
The MinoxTM DeOx System - 2 stages :
This is the ultimate Deoxygenation system configuration available in the market today. It gives extremely small and light units and requires a minimum of maintenance and utilities.
The MinoxTM Deox System - Compact Tower:
By utilizing the MinoxTM process in conjunction with a tower and packing, the same technical features as the 2-stage system are achieved. It will however require more space and support than the 2-stage system, but still significant less than a conventional system. This means that overall, for most new installations, the 2-stage system will be more cost effective.
