ARBOK-OASIS

Overview

ARBOK-OASIS is a mobile, autonomous four-truck complex for restoration and prevention of salinized wells in arid and semi-arid regions. Using ARBOK-VC desalination (100 t/day), the system injects treated freshwater combined with thermally expanded graphite sorbent into saline aquifers, displacing saltwater intrusion and restoring natural aquifer pressure. Supplemented by IoT sensors, AI-driven remote monitoring, and protocol-based water-use governance, ARBOK-OASIS converts "dead" saline wells back to productive freshwater sources within 2–6 weeks per well. Addresses 3–50 million salinized wells globally (India ~3–6 M, Pakistan ~1.2 M, China ~1 M, Sahara/Horn of Africa, Middle East, South Asia).

Applications

Primary use cases: well restoration in saline-intrusion regions; preventive aquifer management; freshwater recovery in water-scarce geographies.

Industries and users: national water authorities, UN/international water programs, arid-region governments, climate-adaptation agencies.

Scale: one unit = ~1 well per 2–6 weeks; clusterable for regional campaigns; BOT (Build-Operate-Transfer) governance model.

Operating Principle

Mobile desalination unit (Truck #1) produces potable water from saline/brackish sources via ARBOK-VC (low-temp vacuum, no chemicals, no membranes, zero discharge). Fresh water is combined with thermally expanded graphite (TEG) sorbent and injected into saline aquifer channels under controlled hydraulic pressure (mild hydraulic fracturing). The combined effect: (1) osmotic displacement of saltwater; (2) TEG creates sorptive "patches" in porous media, acting as natural reverse-osmosis barriers; (3) well depth/water level increased post-treatment to prevent future saltwater re-intrusion via atmospheric pressure. Four-truck support system: power generation (Truck #2), water storage 18 000 t in polymer bags (Truck #3), field crew accommodation (Truck #4).

Key Parameters

Desalination capacity: 100 t/day per unit (ARBOK-VC module).

Energy consumption: ~2 kWh/t (ARBOK-VC baseline).

Field treatment duration: 2–6 weeks per well (depends on aquifer depth, salinity level, geological factors).

Water recovery post-treatment: 100 % potable-grade water output.

Sorbent injection: thermally expanded graphite, custom formulation to create permeability barriers.

Storage capacity: 18 000 t fresh water on-site (polymer tanks, Truck #3).

Remote monitoring: IoT sensors on treated wells; AI-controlled alert/lockdown via SIM, satellite, radio to central command center.

Architecture and Components

Truck #1: A mobile desalination module producing potable water from saline or brackish sources via low-temperature vacuum desalination, mounted on a standard chassis.

Truck #2: On-site power generation and compressor systems, fuel storage, and spare-parts inventory supporting autonomous field operation.

Truck #3: Freshwater storage in flexible polymer tanks, together with lifting equipment and the field-installation components used for sorbent injection.

Truck #4: Crew accommodation (5–6 workers) with sleeping quarters, kitchen, sanitation, and supplies for extended autonomous field operation.

Total system CAPEX: $3.5 M (excludes local taxes).

Central monitoring: IoT + AI control center (remote well-status dashboard, automated lockdown alerts, video surveillance, data logging).

Advantages

Technical: permanent restoration (not temporary cleaning); addresses root cause (saltwater intrusion by aquifer pressure loss); TEG creates durable subsurface barriers; zero chemical discharge.

Economic: $3.5 M mobile unit restores 26–130 wells/year (at 2–6 weeks each); per-well cost $26 k–134 k (depending on complexity); avoided cost of new-well drilling ($600 k–$1 M per well); scalable via multi-unit deployment.

Environmental: climate-resilient (works in arid zones, no external water source needed beyond saline input); AI-optimized water governance prevents re-salinization.

Strategic: geopolitical (addresses water stress in conflict regions); UN-suitable scale; BOT model allows government ownership with private operations; supports SDG 6 (clean water).

Integrations

National water-resource management systems; satellite + ground-based IoT networks; AI governance dashboards; existing well registries; climate-adaptation programs.

Deployment & Operation

Steps: aquifer characterization (depth, salinity, geology) → team mobilization (4 trucks + crew, ~1 week) → well treatment (2–6 weeks per site) → post-treatment monitoring (6–12 months) → team redeploy to next site.

Operating model: government-owned, privately operated (BOT). Licensing/regulatory framework required. Personnel: 1 operator, 1 engineer, 1 technician, 2–3 support staff per site.

TRL

TRL 8 — integrated prototype validated in laboratory and controlled field trials; all subsystems tested (desalination, sorbent injection, monitoring). Ready for pilot commercial deployment. Pending: full-scale field trial on 10–20 wells in target region (3–6 month campaign); regulatory approval and BOT framework establishment.

Market Potential

Global salinized-well inventory: 3–50 million wells (India, Pakistan, China, North Africa, Middle East, South Asia, Australia). No large-scale solution currently deployed. Market addressable if government or UN-level funding secured: restoration of 100–1 000 wells/year over 10–20 years = $2.6 B–$13.4 B program cost; prevents humanitarian water crisis in 500 M–1 B people in affected regions.

Typical Project Economics

Per mobile unit ($3.5 M CAPEX): operating 25–50 wells/year (depending on field logistics) = 2–5 M per-well revenue (via government contract or BOT fees). Annual throughput: 50–100 wells/year per unit. ROI: 7–15 years depending on government funding model and well-restoration fee structure. Multi-unit deployments (5–10 units) enable regional 250–1 000 wells/year capacity.

Risk Factors

Regulatory/governance: requires national legislation and water-use protocols; enforcement of usage limits on restored wells (critical to prevent re-salinization). TEG sorbent offtake science: long-term subsurface durability under different geological/hydrochemical conditions requires field validation. BOT framework: complex to establish across different countries; needs international template. Climate variability: drought or aquifer recharge patterns may affect treatment longevity. Funding: project scale requires UN/World Bank or national government commitment.
