The challenge

The problem this technology addresses

ARBOK produces drinking water, pharmaceutical injection water, ultrapure electronics water, and power-plant generator water — all at 0.7–1 kWh/m³, same system, same footprint. It also processes RO brines, industrial concentrates, and Dead Sea salinity up to 35.5%, delivering Zero Brine Discharge.

ARBOK solution

How the ARBOK system creates value

Low-Carbon Water is a regulatory metric defining the carbon intensity of produced water (kg CO₂/m³). The EU threshold is set at 0.5 kg CO₂ per m³. This technology card evaluates Reverse Osmosis (RO) and ARBOK technology under this metric using energy demand, recovery factor, consumables, brine handling, and lifecycle carbon accounting. The conclusion is binary: RO is structurally incapable of meeting the threshold; ARBOK remains below it permanently.

Low-Carbon Water is not a quality or mineralization parameter. It is the carbon intensity of the entire water production chain, including intake, treatment, transport, waste handling, consumables, and amortized CAPEX.

Carbon intensity formula: CI(water) = (E_proc + E_intake + E_distr + E_waste) × EF(el), plus CI(diesel/gen), CI(chemicals + membranes), CI(brine/discharge), and CI(capex/amortization). Threshold (EU ETS / CBAM): 0.5 kg CO₂/m³.

ARBOK operates under deep vacuum (~–1 bar) instead of the high-pressure membrane separation used by RO (up to 150 bar). Recovery is 100%: 100 m³ in → 100 m³ out, with zero brine. No membranes, chemicals, inhibitors, or washes are used. RO by contrast recovers only 30–50% of feedwater — from 100 m³ seawater it yields 30–50 m³ of product and discharges 50–70 m³ as brine, so delivering 100 m³ of product requires 200–333 m³ of intake (effective recovery multiplier R = 2.0–3.3, base 2.5).

Market and application

Commercial opportunity

Market reference prices: ultrapure water ~$1/m³; pharmaceutical $2–5/m³; RO potable $0.8–2.3/m³; power plants $1.5–3/m³. ARBOK delivers equivalent or higher quality below all of them. Regulatory driver: EU ETS / CBAM low-carbon water threshold of 0.5 kg CO₂/m³, which RO cannot meet.

Cost model at energy price $0.25/kWh.

RO: energy 22.8 × 0.25 = $5.70/m³; chemicals and membranes ≈ $0.20/m³; brine penalties and compliance ≈ $1.50/m³; total $7.4–7.9/m³.

ARBOK: energy 0.72 × 0.25 = $0.18/m³; consumables $0; penalties $0.

Cost ratio: approximately 40× cheaper.

Overview

Low-Carbon Water is a regulatory metric defining the carbon intensity of produced water (kg CO₂/m³). The EU threshold is set at 0.5 kg CO₂ per m³. This technology card evaluates Reverse Osmosis (RO) and ARBOK technology under this metric using energy demand, recovery factor, consumables, brine handling, and lifecycle carbon accounting.

Operating Principle

ARBOK operates under deep vacuum (~–1 bar) instead of the high-pressure membrane separation used by RO (up to 150 bar). Recovery is 100%: 100 m³ in → 100 m³ out, with zero brine. No membranes, chemicals, inhibitors, or washes are used.

Advantages

Structural regulatory compliance: against the ETS/CBAM threshold of 0.5 kg CO₂/m³, RO is always above the threshold and ARBOK is always below it; combined with LongBattery, ARBOK = 0. Zero brine discharge and the ability to process RO brines and industrial concentrates that RO itself cannot handle. No consumables and no hidden embedded carbon — RO carries an unaccounted +0.12–0.15 kg CO₂/m³ from membrane manufacturing, chemical production, cleaning cycles, remineralization, and UV treatment. Universality: one system delivers potable, pharmaceutical, ultrapure electronics, and power-plant water at 0.7–1 kWh/m³. Cost ratio approximately 40× cheaper than RO.
