OWTS™ — Core platform & options

The core platform. The following options can be added as needed.

Modular

Scalable modules for container, vehicle or modular shelter.

Efficient

Optimised filtration and polishing designed for low energy.

Robust

Engineered for variable raw water and demanding environments.

Cloud Control & Monitoring

Connected operations, alarms, dashboards and OTA updates via DABCE Cloud.

Design principles

Neutral, scalable and field‑proven technology for civil and preparedness environments.

No membranes / minimal chemicals*

Low logistics footprint and reduced life‑cycle cost in typical operation.

Minimal automation

Lower cyber exposure and simple field service.

Rapid deployment

Ready to install in hours with few tools.

Climate‑robust

Adapted for Nordic climate and varying raw water.

*Raw water varies; some applications may require additives or pre‑treatment.

Specifications (overview)

Capacity

  • OWTS M: ~200 L/h
  • OWTS L: ~500 L/h
  • OWTS XL: up to ~1,500 L/h

Energy use

~0.5 Wh per litre (typical; depends on raw water).

Power

12/24 VDC, 230 VAC, solar and BESS.

Commissioning

Installation‑ready in under 4 hours.

Raw water

Lake, river, stream or well, including high turbidity.

Monitoring

Local by default; optional cloud control as an added feature. Values are typical and may vary with raw‑water quality and configuration.

Dual‑use potential

One core technology — two domains: civil infrastructure and societal resilience.

Civil use

  • Municipal water
  • Industry & food
  • Agriculture & rural
  • Disaster & crisis response

Preparedness & resilience

  • Off‑grid infrastructure
  • Base camps & critical‑function support
  • Drinking water during disruptions
  • Standardised modules for logistics

How it works (high‑level)

High‑level process description to convey capabilities without disclosing proprietary detail.

  1. 1

    Intake protection

    Coarse/medium screening to protect downstream stages.

  2. 2

    Bio‑treatment stage

    Biological conditioning helps stabilise water quality.

  3. 3

    Advanced oxidation & disinfection

    Oxidative processes reduce microbiology and selected contaminants.

  4. 4

    Built‑in buffer capacity

    Integrated tank evens out flow and provides hydraulic headroom.

  5. 5

    Final polish

    Output polishing for clarity and quality; site‑specific media can be added.

  6. 6

    Off‑grid power integration

    Battery buffer with flexible power inputs: 12/24 VDC or 230 VAC.

Use cases

Remote Communities

Supply for locations with limited infrastructure.

Industrial Sites

Consistent quality for process water.

Emergency Response Units

Rapidly deployable systems for preparedness.
