Project Background

Thailand has many aquaculture farms, livestock farms and agricultural production facilities. These sites often generate wastewater containing organic matter, suspended solids, nutrients and strong odor. 

In this Thailand farm wastewater treatment project, the customer wanted to improve the wastewater treatment environment and reduce odor from collection tanks, biological treatment units and sludge areas. 

Bluwat Chemicals recommended a combined solution using plant-based deodorizer for odor control, BWD decoloring agent for water color improvement and polyacrylamide PAM for sludge-water separation. 

Main Treatment Problems

The wastewater treatment system faced several common operational challenges: :contentReference[oaicite:4]{index=4}

• Strong odor around wastewater tanks
• Organic foul smell from biological treatment units
• High suspended solids after primary treatment
• Dark or yellowish wastewater color
• Sludge accumulation in sedimentation sections
• Poor floc formation during chemical treatment
• Unstable water clarity after biological treatment

Because farm wastewater contains organic waste, feces, feed residues and microorganisms, both odor control and sludge separation were critical for daily operation. 

Products Used in This Case

Plant-Based Deodorizer

Bluwat Plant-Based Deodorizer was applied around odor-generating areas. It is a green liquid product suitable for wastewater treatment plants, livestock farms, aquaculture farms, sludge rooms and environmental sanitation applications. The product can be diluted with water and applied through manual spraying, automatic spray systems or misting equipment. 

BWD Decoloring Agent

BWD Decoloring Agent was used to reduce wastewater color and improve visual clarity. It can be combined with PAC to strengthen coagulation performance and improve treatment efficiency.

Polyacrylamide PAM

PAM was used as a flocculant after coagulation. It helped fine suspended particles and sludge form larger flocs, making sedimentation and sludge separation more efficient. 

Treatment Process

1. Wastewater Collection and Pretreatment

Farm wastewater was collected and sent to the pretreatment section. Large solids, feces, feed residues and floating impurities were removed before biological treatment to reduce system loading.

2. Biological Treatment

The pretreated wastewater entered biological treatment units such as contact oxidation tanks, MBBR reactors or SBR reactors. Microorganisms decomposed organic matter and reduced ammonia nitrogen. Due to the high organic load, odor was generated around the treatment area, where plant-based deodorizer was applied to improve air quality. 

3. Sedimentation and Physical Separation

After biological treatment, wastewater entered sedimentation or physical separation units to remove sludge particles, microbial flocs and remaining suspended solids. Additional chemical treatment was applied if visible color or fine particles remained. 

4. Chemical Clarification

BWD Decoloring Agent was added to improve wastewater color. PAC supported coagulation and PAM was added afterward to form strong flocs. This process significantly improved sedimentation efficiency and water clarity. 

5. Final Polishing

Depending on reuse or discharge requirements, the treated water could be further processed through filtration, disinfection or other polishing systems to improve overall water quality stability. :contentReference[oaicite:13]{index=13}

Application Method for Odor Control

The plant-based deodorizer was mainly applied in the following areas: :contentReference[oaicite:14]{index=14}

• Wastewater collection tanks
• Biological treatment tanks
• Sludge storage areas
• Sedimentation tanks
• Open wastewater channels
• Around the treatment plant

For large treatment areas, automatic spray systems were recommended to maintain continuous odor control and improve operational efficiency.

Application Results

After implementing the Bluwat treatment solution, the wastewater treatment area became easier to manage and the working environment improved significantly. Odor around biological treatment units and sludge storage areas was noticeably reduced. 

The combination of BWD Decoloring Agent, PAC and PAM improved wastewater clarification performance. Suspended solids settled more efficiently, and the treated water showed significantly better clarity after chemical treatment. 

Benefits of the Combined Solution

Suitable Applications

• Thailand aquaculture farms
• Shrimp farm wastewater treatment
• Fish farm wastewater treatment
• Livestock farm wastewater treatment

• Agricultural wastewater treatment stations
• Sludge dewatering rooms
• Wastewater equalization tanks
• Anaerobic treatment areas

Conclusion

This Thailand farm wastewater treatment case demonstrates how Bluwat Plant-Based Deodorizer, BWD Decoloring Agent and Polyacrylamide PAM can work together to improve odor control, wastewater clarity and sludge separation. 

For aquaculture farms, livestock operations and agricultural wastewater facilities facing odor, sludge and wastewater color challenges, Bluwat Chemicals can provide product recommendations, laboratory testing and technical application guidance based on actual wastewater conditions.
