Turnkey Wastewater Treatment Plant - Hatchery
About the caseThis project is a complete Wastewater Treatment Plant to meet the treatment demands of a hatchery. From its development, conceptual/executive design, R&D, mass balance, and WWTP supply, all were developed by WTECH. The entire project architecture was designed for future expansion, making it possible to utilize the existing structure by simply mirroring the processes.
The concept and technology applied successfully met all objectives, and the plant operates with the lowest possible OPEX.

Challenges
- Integration of multiple treatment stages in a Wastewater Treatment Plant, involving physical, chemical, and biological processes.
- Adaptation and assembly of stainless steel equipment, ensuring corrosion resistance and operational durability.
- Efficient treatment of wastewater with varying loads, solids, fats, and chemical compounds.
- To ensure efficient solid-liquid separation using a lamellar flotation/settlement tank and a secondary clarifier.
- Optimization of the aeration stage with OXYTARGET Membrane, ensuring high oxygen transfer.
- Efficient equalization control to dampen peak flow rates and organic load.
- Proper chemical conditioning with lime preparation and controlled dosages.
- Management of generated sludge, including dewatering with a filter press.
Results
- High efficiency in removing solids, organic load, and contaminants.
- Excellent performance in the biological stage with the use of the OXYTARGET Membrane.
Operational stability provided by the equalization tanks.
- Efficient solid-liquid separation with lamellar flotation/settlement tank and secondary clarifier.
- Significant reduction in sludge volume with the use of a filter press.
- Greater durability and reliability of stainless steel equipment.
- Optimizing the consumption of chemical inputs through proper lime preparation.
- Improved operational control and ease of system maintenance.
