SHE Aqua CAT Technology

SHE Aqua CAT Technology Rethinking Water Treatment

Our proprietary technology, SHE Aqua CAT, is the culmination of over a decade of meticulous research, extensive field-studies, and unwavering development. SHE Aqua CAT is designed to address the most challenging aspects of water purification, from removing contaminants to improving the overall quality of water for both human consumption and environmental health.

Comparing to other conventional treatment technologies, SHE Aqua CAT has:

Remarkably less water wastage in backwash

> 98% Water Retention Rate

Lower energy consumption, Smaller foot print

~30% lower than AOP / RO
as low as ~0.1 kWh/m³

Degradation of harmful organic and removal of inorganic compounds

Instead of filtering them by physical membranes for concentration and disposal in wastewater system.

What is SHE Aqua CAT?

SHE Aqua CAT stands for Catalytic Advanced Treatment– a revolutionary approach to ensuring the purity and safety of water.

SHE Aqua CAT is a powerful, low energy and low operating cost treatment process that removes, degrades or destroys multiple contaminations simultaneously to produce high quality water from most natural or wastewater sources.

This unique blend of Catalytic Oxidation (CO) and Catalytic Advanced Oxidation (CAO) reactions delivers an integrated water treatment solution that stands out for its efficiency.

A series of processes take place simultaneously as the preconditioned water comes into contact with the selected media catalytic bed, such as:

Catalytic Advanced Oxidation (CAO)

Catalytic Oxidation / Reduction

Co-precipitation

Disinfection

All partly stable oxygen donors (NaOCI, KMnO₄, O₃…) decompose releasing oxygen

SHE Aqua CAT delivers high performance in:

Mineralisation and removal of organic matter

Removing metal & metalloids

Effective full-spectrum disinfection

Remarkable color removal

Taste and smell improvement

Phosphorous removal

Why Water Treatment for Municipal Water

Issues with potable water in building:

General Public Distribution System

Water Utility Plant can provide regulatory compliant water, but contamination can happen in the aged distribution network.

While chlorination cannot eliminate all contaminations, such as bacteria and protozoa, Chlorine is corrosive and is capable to dissolve heavy metals into water.

Proven by epidemiological research, residual organic matter becomes food for bacteria, resulting in bacterial slime development to amplify biological contamination.

Contaminants of Emerging Concern (CECs)

CECs are chemicals and toxins found in water that may cause ecological or human health impacts and are not currently regulated, posing the needs of water treatment for municipal water. Examples are pharmaceuticals, pesticides & herbicides, household cleaning chemicals, PFAS micro & nano-plastics.

Building Distribution System Maintenance

Maintenance for the building distribution piping is hard to be conducted

The Key to Advanced Treatment - CAT Catalysts

CAT0

Exceptional in catalytic oxidation, perfect for groundwater and waters with heavy metals and limited organics.

CATM

Improved capacity for organic matter degradation and recoverable after damage, ideal for municipal water treatment.

CATX

Our highest performing catalyst, achieving over 70% removal of natural organic matter, suitable for surface water and secondary effluent wastewater.

Demonstrated Efficacy and Adaptability

SHE Aqua CAT technology has been tested in a comparative study using river water, known for its variable quality and range of contaminants. This study showcased its remarkable performance, robustness, and adaptability when treating natural, dynamic water systems.

Our Catalytic Reactor
The Heart of SHE Aqua CAT

The core of our system is the catalytic reactor, where water flows through a bed of specialized catalysts, achieving purification through three core processes

Normal flow for daily operation

Backwash flow to remove solids and regenerate the system

Rinse flow to ensure thorough cleaning and readiness for the next cycle

Conditioning
Raw Water is dosed with proprietary chemicals:

Catalytic Advanced Oxidation
High levels of Hydroxyl radicals are created:

Remove odor and color
Removal of PFAS and Contaminants of Emerging Concern
No chlorination, thus no chlorinated DBP & less corrosion

Reduce organic matter to eliminate bacteria growth
Degrade / remove micropollutants to produce healthier water
Replace residual chlorine with more powerful but non-corrosive disinfectant

Unmatched Performance in Natural Organic Matter (NOM) Degradation

SHE Aqua CAT technology sets a new standard in water treatment, excelling in degrading Methylene Blue, a common indicator of NOM. Rigorous tests demonstrate its superior performance and consistency in reducing Total Organic Carbon (TOC) levels in raw water, affirming our leading position in the industry.

How Does SHE Aqua CAT Work?

Our Catalytic Advanced Treatment process is a multi-stage system that includes:

Advanced Oxidation

This process involves the production of powerful hydroxyl radicals that non-selectively degrade organic materials, ensuring the breakdown of pollutants to their most basic forms.

Catalytic Materials

Utilizing a multi-metal oxide granular material, our process leverages catalysts that facilitate reactions without being consumed, thus enabling efficient and continuous treatment.

Catalytic Oxidation & Co-Precipitation

Specifically targeting the removal of arsenic and other inorganic contaminants, our system employs advanced techniques that leave water free from harmful substances.

Potable Water Application

Ensuring that drinking water is safe, our system addresses all necessary parameters to meet and exceed regulatory standards for potable water.

Municipal Wastewater Recycle

By treating secondary effluent from municipal wastewater, we extend the lifecycle of water, reducing waste and contributing to sustainability.

SHE Aqua CAT's system outperforms conventional methods by delivering superior water quality in a more streamlined and energy-efficient process.

Wastewater
Treatment Plant (WWTP)

The starting point for our advanced treatment, where primary and secondary contaminants are significantly reduced.

Conditioning Clarifier

Prepares the water for the advanced stages of treatment by further clarifying and conditioning it.

Ultrafiltration (UF)

A cutting-edge filtration method that ensures the elimination of any remaining impurities, securing pure and safe water.

The Result - Drinkable Water

Our streamlined process aims at the provision of drinking water that is not just safe, with healthier standard.
