Proposal: Geodyn Solutions – Green Water Recycling and Energy Plant in South Africa
Project Overview
- Project Name:Green Loop Utility Plant – South Africa
- Location:To be determined in consultation with local municipalities
- Plant Capacity:Treats 150,000 m³/day of municipal wastewater
- Capital Investment (CAPEX):$250 million (including 20% contingency)
- Electricity Production Cost:$0.19/kWh
- Water Recycling Rate:90%
- Fertilizer Production:From recovered biosolids and nutrients
Objectives
- Transform municipal wastewater into clean water and biosolids.
- Use biosolids to generate electricity using ORC (Organic Rankine Cycle) and heat recovery.
- Recover phosphorus, nitrogen, and potassium to make commercial-grade fertilizer.
- Achieve net water reuse and zero-discharge operations.
- Support sustainable agriculture and grid resilience.
Key Components and Technologies
- Microbial Treatment & Algal Reactors– First stage for organic load breakdown.
- Advanced Membrane Filtration (MBR/UF/RO)– For water purification.
- Sludge Digestion & Dewatering– To concentrate biosolids.
- ORC & Steam Turbine Units– Converts biosolids into heat and electricity.
- Nutrient Recovery Units (Struvite Crystallization)– Extracts NPK.
- Solar Panels & Biogas Capture– Enhances energy efficiency and reduces emissions.
Implementation Steps
Phase 1: Feasibility and Planning (Months 1–6)
- Conduct site selection, EIA (Environmental Impact Assessment), and secure permits.
- Finalize MoUs with local government and utility partners.
- Engage engineering firms and technology partners.
Phase 2: Design and Procurement (Months 7–14)
- Detailed engineering designs.
- Equipment procurement: microbial bioreactors, membranes, turbines, nutrient separators.
- EPC (Engineering, Procurement, Construction) contractor appointment.
Phase 3: Construction and Installation (Months 15–32)
