Treating of Complex Waters
Freezing out the Water Part from a Solution with Dissolved Chemicals.
Principle
Method of Utilizing the Refrigeration Energy by Freezing out Water
in a Contaminated Fluid without the Addition of Chemicals.
Theory
When a Solution Freezes, the Ice Crystals Reject the Solute. The Dissolved
Substances increase in Concentration, allowing an Operating
Factor Ranging from 1 to 40 in the Remaining Water.
Technology
TM
The HybridICE Technology consists of a Water Freeze Crystallisation Plant
and a Filter System to separate the clean water from the contaminated concentrate.

MINING & INDUSTRIAL SECTOR
TM
The HybridICE Technology is based on the principles of conventional
refrigeration. HybridICE can be integrated into an existing infra structure
typically found in both the Mining and Industrial Sector. The technology is ideal
for Retrofitting and Modernising existing Refrigeration plants.
TM
Deep Cast Mines have large refrigeration capacities. Existing cooling systems can
be retrofitted for water treatment and in the process improve the existing
refrigeration performance.
BRINE STREAM TREATMENT FOR REVERSE OSMOSES
Membrane technologies are widely installed and used by Industry. The produced
Brine Streams from a Reverse Osmoses (RO) is a critical issue in many countries.
The treatment of Brine Streams is energy intensive and therefore extremely costly
to operate, as these steams are predominantly being fed into Evaporation ponds.

TYPICAL COMPLEX WATER
Complex Waters such as Acid Mine Drainage (AMD) and Brine Steams contain
Freezing Point Depressant Substances (FPDS) such as chlorides and sulphur.
Both AMD and Brine Streams can be used as efficient and environmentally
friendly secondary refrigerant in the HybridICE Process without the need for
Glycol .

ENERGY AND COST ENHANCEMENT
HybridICE - offers itself as an economically feasible solution to Recover Fresh
Water were Energy is Critical and Disposal of Contaminated Fluids are Costly.
TM
Process is not sensitive to impurities e.g. mud / metals unlike membrane
technology.
HybridICE Process requires no chemical addition.
TM
Waste heat from the refrigeration cycle can be utilized to heat the concentrate.
The thermo-physical Properties of contaminated fluid as secondary refrigerant
makes it an ideal medium for thermal energy storage, transport and transfer of
cold energy.
The Process is ideal to reduce air temperature and humidity in the mines.

FEASIBILITY
Contaminated Fluid is an efficient two-phase Secondary Refrigerant
Retrofitting and Utilizing of existing Refrigeration Equipment possible
Significantly reduces the amount of Primary Refrigerant
Usable Water can be recovered without addition of Chemicals

Eco-MeRe™ ENHANCEMENT TECHNOLOGY
Acid Mine Drainage (AMD) often contain high levels of metals
apart from other harmful and toxic substances. When a
HybridICE System is installed, the contaminated fluid is
concentrated.
TM
This concentrated fluid can contain valuable metals such as
Cobalt, Copper, Nickel and Uranium. These Metals can be
recovered with the eco-MeRe™ System, a complimentary
product of HybridICE .
TM
The eco-MeRe™ is an electro-coagulation technology. This
System has been designed to salvage valuable metals and
remove iron and other harmful substances effectively. The
combination of the eco-MeRe™ and HybridICE can ensure
that the recovered water can be used as industrial water or
returned safely back into the environment.
