Blueprint: Woodchip Denitrification Bioreactor for 20 Hectares of Drained Cropland — Build Specification
Year: 2026
Type: article
Abstract: DESIGN BLUEPRINT — SIMULATED, NOT MEASURED — NOT BUILT. Build specification for the woodchip denitrification bioreactor designed in the source paper: Aldred, William Alexander, 'Edge-of-Field Runoff Capture Sized from First Principles: A Woodchip Denitrification Bioreactor for 20 Hectares of Drained Cropland', DOI 10.5281/zenodo.24108669. The blueprint specifies the 612.0 m3 woodchip bed (60.0 m x 8.5 m x 1.2 m) on 0.255% of a 20 ha drained field: excavation dimensions and profile, liner and media quantities, inlet and outlet water-control structures, flow distribution, construction sequence, operating envelope (simulated 26.3% seasonal nitrate removal; bypass in rainfall events above about 26.5 mm in 24 h), tolerances, failure modes, and maintenance and media replacement schedule (simulated carbon-depletion life 26 years). All performance is simulated in the source paper, not measured; nothing has been built. Derived build quantities are computed in the deposited compute.py and results.json. AI use disclosed: Dave, an AI research system, assisted with the derivations and preparation.
