Revive every drop of water, building a cleaner future for the Earth.

Revive every drop of water, building a cleaner future for the Earth.

Our Mission

Our mission is to protect nature's water resources, focusing on the development of PVA microbial immobilization technology and adsorbents for phosphates, precious metals, and radioactive substances. We are the world's first company to successfully apply this technology in the industrial sector, providing efficient solutions for wastewater treatment and working to clean up contaminated rivers and lakes. In addition to Taiwan, we aim to help improve water quality in places like the Ganges River in India and water sources in Africa, allowing these resources to be restored to cleanliness and continue nurturing the healthy growth of future generations globally. Our goals are closely aligned with the United Nations Sustainable Development Goals, including clean water and sanitation, and good health and well-being.

What is PVA?

Our PVA microbial immobilization gel beads (PVA bio-balls) are an innovative bio-carrier designed for efficient wastewater treatment and pollutant degradation with the following features:

Size: bead diameter is approximately 3–4 mm, customizable up to 8 mm based on requirements.
Low carbon emissions: Produces minimal sludge and can be degraded into biofuels like ethanol or methane.
High microbial content: Entrapped with immobilized microorganisms, with a microbial content of 6-9%.
Eco-friendly material: Made of polyvinyl alcohol (PVA) and water, biodegradable according to EN-13452 and 14855-1.
Edible safety: Can be applied for food coatings, safe and non-toxic, with usage below 2.0%.
Hydrophilic: No formation of marine microplastics.

Technical Advantages

Our PVA microbial immobilization technology has made significant contributions to traditional biological treatment methods. Compared to Moving Bed Biofilm Reactor (MBBR) technology, we offer several key advantages:

01

Simplified Ammonia Nitrogen Treatment

By using PVA bio-balls entrapped with pig manure wastewater sludge and applying intermittent aeration (1 hour on/off) boosts anaerobic ammonia-oxidizing bacteria, directly converting ammonia nitrogen to nitrogen gas. This process is simpler to operate than traditional systems.

02

Degradation of Toxic Substances

Microorganisms within PVA bio-balls are shielded from external factors and toxins. The high microbial load in the entrapped system provides hydrolytic enzymes for degrading toxic substances, such as NMP (N-Methyl-2-pyrrolidone). This has enabled Formosa Smart Energy’s new battery plant to reduce the reactor retention time from 9.5 days to 1.5 days.

Degradation of Toxic Substances

03

Removal of Carcinogens from Water

Our technology can regulate the microbial community composition in activated sludge. For example, bio-balls entrapped with Pseudomonas putida can effectively remove carcinogenic substances like 1,4-dioxane from water.

04

High-Efficiency Denitrification

Our bio-balls technology, paired with patented additives, significantly reduces reaction lag and shortens reaction times. For NO₃-N concentrations of 500 mg/L, a 90% removal rate is achieved within one hour; for 2000 mg/L, this is accomplished within 18 hours. If the influent temperature exceeds 35°C (within the microorganisms' tolerance), reaction time can be reduced to 10-80 minutes.

High-Efficiency Denitrification

05

Low Sludge Production

Based on the principle of resting cells, our technology reduces sludge production to just 0.05-0.1. This is because more metabolic pathways lead to anaerobic respiration, significantly reducing the amount of sludge generated.

Low Sludge Production

Technical Applications

Our PVA bio-balls are protected by global patents in Taiwan, South Africa, the UK, China, India, Japan, and the United States. The key feature is the etherification modification of traditional PVA microbial immobilization gel beads, which differs from Kuraray's polyacetal method that uses strong acids and high temperatures. We use a more eco-friendly etherification process with a natural purification mechanism during phase transition, similar to silicon wafer purification. This allows the PVA bio-balls to form a stable polyurethane (PU) ether layer.
