What is
Contaminant Destruction & Removal?
Water Contaminant Destruction and Removal (CDR) refers to the processes and methods used to either eliminate or reduce undesirable substances in water. Contaminants in water can range from physical particles to chemical compounds and biological organisms.
There are two general approaches:
Destruction
Involves breaking down harmful contaminants into harmless constituents.
Removal
Involves physically or chemically separating and extracting contaminants from the water.
G-DECK TEAM
NOTE: Many of these technologies are being used in China today but are not delivering the results G-DECK delivers.
The difference is in HOW we use the technologies.
Proprietary Processes and Design
G-DECK’s advanced water treatment systems utilize high technology components, integrated to provide highly efficient destruction and removal of contaminants from multi-contaminant water sources, to supply water at Level 2 up to ultra pure, including “healthy” drinking water.
Compared to the systems that currently dominate the industrial treatment market,
G-DECK systems feature
>25% lower capital costs (CAPEX),
>25% lower operational costs (OPEX),
minimized waste products, reduced water usage, and substantially reduced energy consumption, while maximizing water production with minimal to zero wastewater.
Integrated Technologies
Technologies include, though are not limited to the following:
• Biological systems that degrade contaminants to safe chemicals
• Destructive technologies that break high strength chemical bonds apart to form safe chemicals
• Addition systems to transform contaminants into safe chemicals or to create conditions that improve efficiencies of other destructive technologies
• Adsorption technologies to concentrate contaminants
• Desorptive recovery technologies to extract value from the water source
• Regenerable technologies to remove contaminants, but reduce carbon footprint and greenhouse gas generation

CDR – Destruction Technologies
G-DECK systems utilize many of the same technologies as some competitors. But G-DECK systems integrate the technologies in proprietary system designs to achieve superior results.
Examples of Destruction Technologies
used by G-DECK, include the following:
Chlorination/Chemical Disinfection:
This is a widely used method for destroying pathogenic microorganisms in water. Chemicals like chlorine, chloramines, or ozone react with organic and inorganic substances and can inactivate bacteria, viruses, and other pathogens.
Ultraviolet (UV) Radiation:
UV light can effectively destroy bacteria, viruses, and certain organic compounds. When these contaminants absorb UV light, their DNA (for microorganisms) or molecular structure (for organic compounds) is altered, making them non-functional.
Ozonation:
Ozone (O₃) is a powerful oxidant that can destroy a variety of contaminants, from microorganisms to some organic and inorganic substances.
Advanced Oxidation Processes (AOP):
These are treatment processes that involve the generation of hydroxyl radicals, highly reactive species that can oxidize and break down a wide range of contaminants.
CDR – Removal Technologies
Examples of Removal Technologies
used by G-DECK, include the following:
Biological Treatment:
Uses beneficial microorganisms to consume and transform organic contaminants into more harmless substances. Commonly employed in wastewater treatment.
Filtration:
This is a physical process where water passes through a medium that captures and retains particles and certain contaminants. Common types of filters include sand filters, activated carbon filters, and membrane filters.
Ion Exchange:
A process where undesirable ions are replaced with less harmful ones. It's commonly used to soften water and to remove specific contaminants like arsenic, nitrate, and perchlorate.
Adsorption:
Contaminants adhere to the surface of an adsorbent material. This process can effectively remove certain organic compounds, tastes, odors, and chlorine byproducts.
Flotation:
Air is introduced into the water, forming bubbles that attach to contaminants and carry them to the surface where they can be removed.
Reverse Osmosis (RO):
Amembrane-based process that can remove many types of dissolved salts, organic compounds, and microorganisms. RO is inefficient as a primary treatment option, but it can be used effectively as a smaller component once most of the contaminants have been removed.

Systems are Designed to Maximize Efficiency
For the two systems shown on this page, the contaminants are the same; however, different flow rates and contaminant concentrations required different system designs to maximize efficiency while minimizing costs. The treated and released water exceeds California drinking water standards.
