Water and Wastewater Treatment (WWT)
Decarbonisation of Water & Wastewater Treatment plants
Towards a Sustainable Solutions
Get Ahead
Water companies that produce treated and drinking water show an increasing interest in using O₂ to reduce their carbon footprint. In general, the public health and environmental regulations are encouraging the industries towards using Ozone, O3 as an alternate to treat micropollutants, bulk sludge and hard Chemical Oxygen Demand (COD).
Safety
Gases is able to remove microbes, contaminants, etc...inside water. It can also avoid the needs to use strong chemicals (e.g. acid, alkaline, chlorine, etc...) to treat water. Hence, creating a more sustainable and safer environment.
Specific Expertise
Equipment that preheats large volumes of combustion Air can get quite costly. Our gas technology uses less energy to preheat small volumes of combustion Oxygen.
Digitalisation
Our solutions can be digitalise for remote monitoring in-line with the Data Analytics & Artificial Intelligence applications in the Industry 4.0 era
Biological Treatment
A recommended alternative to Water & Wastewater Treatment (WWT) is Oxygen, O₂ injection. It can increases the WWT plants' treatment capacity without needing to enlarge their basin sizes. Biological treatment using, O₂ injection intensifies aerobic process in the basins. The energy usage is lower and the stripping phenomena will be minimal or avoided. It produces almost no GreenHouse Gases (GHGs), Volatile Organic Compounds (VOCs) emissions and odours.
Energy Savings
Energy efficiency of oxygen injection systemHigh ratio of kg of O₂ injected per kWh of dynamic oxy-injector power consumption.
Carbon Savings
Measurement of Greenhouse Gases (GHGs) from exhaust gases
Biological treatment with oxygen injection on wastewater plant can lower GHGs emission (e.g. CH4, CO₂, etc..) due to decomposition of organic materials.
Peace of Mind
Optimum process control to meet stringent environmental requirements with peace of mind- Low maintenance
- Safe, Stable and reliable operations
- Continous process and operations monitoring
- Digitalisation and remote monitoring capability
pH Control
CO₂ injection is an effective and economical alternative to neutralising water pH level. This pH neutralisation method reduces impact on the environment because it does not generate secondary pollution. It permanently retains carbon in the form of bicarbonate, which is safe to the environment.
Environmental Friendly
pH regulation without harmful emissions- No harmful emissions such as chlorides or sulfates
- A more gentle method of water pH control
- Low risk of corrosion vs chemicals and increase in lifespan of plant equipment
Peace of Mind
Fully automated pH control system for CO₂ injection- Unlike traditional mineral acid treatments, there are no shower requirements nor carcinogenic fumes
- The cost of CO₂ is competitive against mineral acids
- Reduce overhead operating costs due to chemical and non-pumping operations
Tertiary Treatment
Ozonation, O3 is a disinfectant solution neutralizes biological matters, such as bacteria, viruses, and parasites. In addition, it can also remove harmful metals such as manganese and other pollutants e.g. phenol from water. Besides that, more reduction of suspended solids can be achieved with greater ozone dose.
