Autofloc Smart Chemical Dosing in the Civil Construction Industry
Client Background & Requirement
Project Overview
Our client, Auto-Floc, is a New Zealand-based company providing automated flocculant dosing solutions for sediment-laden runoff at construction and earthworks sites. The Auto-Floc system is designed to improve environmental compliance, reduce manual handling of chemicals, and increase operational efficiency through real-time monitoring and automation.
Background
Managing stormwater runoff and sediment control is a critical part of civil construction in New Zealand. Auto-Floc developed a solar-powered, lightweight dosing system capable of delivering precise flocculant amounts in response to site-specific environmental data. With real-time data reporting via a dedicated web and mobile platform, the Auto-Floc system provides a proactive, automated approach to stormwater treatment.
Challenges Faced
Manual Chemical Handling: Traditional flocculant application required significant on-site labour and increased safety risks.
Compliance Requirements: Increasing regulatory demands around stormwater treatment require more accurate and auditable chemical dosing.
Environmental Impact: Conventional dosing systems contributed to waste through smaller containers and reactive dosing methods.
FlexWare Provided
Custom Web Application & IoT Integration: Built an intelligent cloud-based platform enabling remote control, monitoring, and scheduling of Auto-Floc units across multiple sites.
Data-Driven Dosing Logic: Developed software that adjusts chemical application based on rainfall, flow rate, and tank levels to ensure precise dosing and compliance.
Low Power Embedded System Design: Utilized the Particle IDE to create a battery-operated, low-power embedded system, ideal for remote, solar-powered deployments with minimal maintenance.
Custom Hardware Development: Designed and manufactured a custom PCB tailored to the mechanical constraints of the Auto-Floc enclosure, ensuring robust performance in harsh outdoor conditions.
Real-Time Alerts & Notifications: Implemented SMS and in-app alerts for low tank levels and system faults, reducing downtime and enabling proactive management.
