Technical overview

SND Container System — Modular Containerized Treatment

A modular 3-unit containerized water treatment system that brings SND biological treatment and IoT monitoring together in a deployable, reusable package. Pond wastewater is drawn into the system, passes through pre-treatment (Unit 1), core SND biological treatment (Unit 2) and polishing (Unit 3), and clean water returns to the pond.

Treatment flow

Intake
Pond wastewater drawn into the system
Return
Clean water returns to the pond
Unit 3 — Polishing
Final purification & quality check
Unit 1 — Pre-treatment
Initial filtration & SND bacteria
Unit 2 — Core treatment
Active SND biological process

Fitted to each container unit

Equipment
IoT sensors, air pumps, temperature control and SND bacteria

Best for

Aquaculture farms needing on-site containerized wastewater treatment

Key product advantages

  • Modular, deployable and reusable — SND treatment and IoT monitoring combined in one package
  • Built-in IoT sensors, air pumps and temperature control in every container unit
  • Built-in air pumps supply oxygen for the SND bacteria, and flow control is by automated hydraulic retention time (HRT)
