Water scarcity poses a
significant hurdle in Vietnam,
profoundly affecting livelihoods
and agricultural productivity.
9 DragonsCity stands at the
forefront of tackling this challenge,
leveraging the power of algae and
microbes to offer cost-effective
and eco-friendly solutions,
ensuring Vietnam’s water security
for generations to come.

A COMPREHENSIVE
STRATEGY WITH ALGAE
AND MICROBES
Given Vietnam’s diverse topography and varying climate patterns, a multifaceted approach to water management is imperative. Our strategy integrates the potent capabilities of
algae and microbes, driven by our innovative proprietary technologies:
1. Atmospheric Water Generation (AWG): Utilizing advanced microbial sorbent-based technology and solar energy, our AWG systems extract clean water from atmospheric moisture.
2. Solar-Powered Desalination: Employing our proprietary membrane distillation techniques enhanced with microbial processes, our desalinationn plants convert seawater into freshwater with minimal ecological footprint.
3. Wastewater Recycling with Membrane Bioreactors (MBR):
Combining proprietary biological treatment and membrane filtration processes, our MBR systems, driven by microbial biofilms, recycle wastewater, producing high-quality effluent suitable for diverse applications.
4. Smart Groundwater Extraction:
Utilizing smart drilling technologies and solar-powered pumps, we ensure sustainable groundwater extraction,
complemented by our proprietary aquifer recharge methods which include microbial bioaugmentation to enhance water quality.
5. Rainwater Harvesting:
Leveraging our proprietary technologies and algal systems, we efficiently collect and store rainwater, reducing dependency on conventional water sources.
6. Reservoir Optimization:
Our IoT-powered automated control systems monitor reservoir water levels in real-time, while floating algal beds
generate renewable energy and minimize evaporation through reduced surface exposure.
7. Community Engagement:
Through educational initiatives and training programs, we empower local technicians and community leaders to adopt
sustainable water management practices using algae and microbial solutions.

ALGAL AND MICROBIAL
INNOVATIONS FOR
WATER PURIFICATION

9 DragonsCity pioneers the use of algae and microbes for water purification through a range of proprietary technologies, including:
Microbial Technologies
Biofilms:
Utilized in bioreactors, biofilms are communities of microorganisms attached to surfaces. They can degrade organic pollutants and remove nutrients from wastewater.
Activated Sludge:
A process where aerated microbial cultures degrade organic matter in wastewater. It’s commonly used in municipal and industrial wastewater treatment plants.
Anaerobic Digesters:
These systems use anaerobic bacteria to break down organic waste, producing biogas (methane) and reducing sludge volume.
Microbial Fuel Cells (MFCs):
Devices that use bacteria to convert organic matter directly into electrical energy while treating wastewater.
Anammox (Anaerobic Ammonium Oxidation): A biological process that removes nitrogen from wastewater by converting ammonium and nitrite into nitrogen gas.
Denitrifying Bioreactors:
Systems that use denitrifying bacteria to remove nitrate from water, converting it into nitrogen gas.

Phosphorus-Accumulating Organisms (PAOs):
Microbes that uptake and store large amounts of phosphorus, helping to reduce phosphorus levels in wastewater.
Constructed Wetlands:
Man-made ecosystems that use plants, soil, and microbial communities to treat wastewater
through natural processes.
Algal Technologies Algal Ponds and Lagoons:
Large, shallow ponds where algae grow and uptake nutrients from wastewater, effectively reducing nutrient loads and producing biomass
that can be harvested for biofuels or other products.
Photobioreactors:
Controlled systems that cultivate algae using light, carbon dioxide, and nutrients to treat wastewater and produce algal biomass.
Algal Turf Scrubbers:
Systems where algae grow on screens or mats in flowing water, absorbing nutrients and pollutants as the water passes over them.
Microalgae-Bacterial Consortia:
Synergistic systems where algae and bacteria work together to degrade pollutants, with algae providing oxygen through photosynthesis for aerobic bacteria.
Phycoremediation:
The use of algae to remove or neutralize pollutants, heavy metals, and toxins from water, leveraging their natural uptake and detoxification
processes.
Floating Algal Beds:
Platforms that support algal growth on the water surface, enhancing nutrient uptake and providing a habitat for beneficial microorganisms.
Algal Bioremediation:
The use of specific algae strains to target and degrade contaminants such as pharmaceuticals, pesticides, and heavy metals in water.
By employing these microbial and algal technologies, water treatment systems can achieve higher levels of purification, reduce reliance on chemical treatments, and contribute to sustainable and eco-friendly water management practices.
