Biologically Active Pervious Structure (BAPS)

Description:

BAPS is a sustainable technology composed of a porous concrete structure embedded with biochar derived from waste biomass and inoculated with a consortium of microorganisms. This combination facilitates biosorption, biotransformation, and biodegradation of pollutants found in urban runoff water. The biochar is produced from pyrolyzed invasive weeds and agricultural waste, then blended with Portland cement to create pervious concrete blocks. Bacterial biofilms formed within the blocks enhance contaminant removal, targeting pollutants such as E. coli, organic compounds, nitrates, and phosphates. The technology provides a novel approach to minimizing pollution and erosion through environmental remediation.

Key Advantages:

• Effectively captures and degrades various chemical and biological contaminants in runoff water.
• Utilizes waste biomass converted to biochar, promoting sustainability and waste reduction.
• Enhances microbial activity within a durable porous concrete matrix for long-term pollutant treatment.
• Reduces chemical oxygen demand (COD), nitrates, phosphates, and harmful bacteria in water.
• Adaptable manufacturing methods, including different aggregate sizes and biochar incorporation techniques.
• Mitigates erosion and pollutant contamination in diverse environmental settings.

Problems Solved:

• Urban runoff pollution caused by organic, inorganic, and microbial contaminants.
• Ineffective traditional runoff water treatment methods lacking biodegradation capabilities.
• Excess nutrients like nitrates and phosphates that lead to water eutrophication.
• Waste biomass disposal through beneficial reuse as biochar in construction materials.
• Environmental degradation and erosion related to contaminated surface water flows.

Market Applications:

• Stormwater management systems in urban and suburban infrastructure.
• Green building materials and sustainable construction projects.
• Environmental remediation in agricultural runoff and industrial wastewater treatment.
• Public and private landscaping areas requiring erosion and pollution control.
• Municipal water quality improvement programs and ecological restoration initiatives.
