Sustainable Wastewater Systems Design
|
Primary treatment in the Oldcastle systems is performed by algae, a green plant grown through photosynthesis, in a symbiotic relationship with bacteria, thus yielding a very sustainable design. Algae:
- Use Solar Energy
- Remove nitrogen and phosphorous
- Convert carbon dioxide to oxygen and renewable biomass

AlgaePac Wastewater Systems – Benefits/Advantages
|
- Low energy usage
- Tertiary treatment
- Reduced greenhouse gas emissions
- Low maintenance for simple technology
- Advanced ecological treatment using environmentally sensitive methods
|
|
Why Package Plants?
|
- Factory produced concrete structures are cast in controlled environmental conditions for the highest quality
- Pre-assembled components from Oldcastle factories provide for faster installation/construction at the project site.
- Package plants can be used as stand-alone treatment systems, or as polishing systems to provide additional treatment to existing processes.
|
|
Why Distributed or Decentralized Wastewater Treatment?
|
Distributed wastewater systems are used in locations where connecting to a sanitary sewer is not possible due to cost, availability, or where the municipal system is near capacity. Distributed systems provide very effective and sustainable wastewater treatment near the source. Package plants can also be used for small rural communities.
Simple and dependable, naturally
