About Commissioning Waste Management Dairy Manure CSTR (Continuous Stirred Tank Reactor) Inoculum Recycle Loop Bio-CNG Plant

This facility processes dairy manure through a wet anaerobic digestion configuration utilizing a primary Continuous Stirred Tank Reactor (CSTR) paired with an active **inoculum recycle loop**.

* **Digester Flow Dynamics & Feeding:** Raw substrate undergoes de-gritting and homogenisation before positive-displacement progressive cavity pumps meter the slurry continuously into the reactor base. An effluent clarification and centrifuge dewatering stage separates active digestate solids, routing an enriched anaerobic consortium stream back to the feed manifold. This loop optimizes hydraulic retention time (HRT: 2228 days), enhances microbial loading, and mitigates washout risks during fluctuating organic loading rates.

* **Mechanical Mixing & Thermal Regime:** Digester homogeneity and scum prevention are achieved via multi-level, low-shear mechanical agitators coupled with localized liquid recirculation nozzles. The system operates strictly within the **mesophilic thermal regime (38C 1C)**, regulated by external shell-and-tube heat exchangers and insulated wall heating jackets.

* **Biogas Upgrading & Energy Recovery:** Raw biogas passes through biological desulphurization and chilling condensers before entering a high-pressure, multi-stage membrane permeation system to strip $\text{CO}_2$, yielding fuel-grade Bio-CNG ($\ge 96\%\ \text{CH}_4$). Parasitic process heat is sustained by waste-heat recovery from the compression trains and an auxiliary dual-fuel boiler, achieving closed-loop thermal and energetic efficiency.
