Effective Solutions for Every Project
Dose Injection Systems
The DoseBox is a smart, reliable solution for injecting treatment chemicals into pumped dirty water flows. Designed for erosion and sediment control applications, it automatically doses coagulants and flocculants—such as Polyaluminum Chloride (PAC)—only when water is flowing, ensuring efficient treatment while minimising chemical use.
AUTONOMOUS DOSING TECHNOLOGY
Power. Dose. Clarify.
Title
Powered by solar energy, the DoseBox operates independently of mains power, making it ideal for remote sites, temporary works, and off-grid locations. The system can be configured with either a flow switch or flow meter, providing flexible and accurate dosing across a range of site conditions.
By delivering consistent chemical dosing, the DoseBox promotes rapid floc formation, improving sedimentation and the removal of suspended solids. It is commonly used in conjunction with downstream treatment systems such as lamella clarifiers, sediment tanks, and settling ponds, where it enhances overall water treatment performance.
How Does our DoseBox system work
Water Pumping: Dirty water, containing suspended solids and fine particles, is pumped through a pipeline.
Coagulant Injection: The DoseBox injects a precise amount of coagulant into the water stream.
Flow-Based Operation: The DoseBox can be activated by either a flow switch or flow meter:
A flow switch detects when water starts flowing, automatically triggering the injection of PAC.
A flow meter measures the rate of water flow, allowing the system to adjust the PAC dose proportionally, ensuring precise chemical dosing based on the water volume.
Key Benefits of the Solar-Powered DoseBox System
Sustainable Power: By using solar power, the DoseBox operates without requiring a grid connection, making it ideal for remote sites or projects prioritizing environmental sustainability.
Automated and Precise Control: Whether using a flow switch or flow meter, the system delivers precise, controlled PAC dosing. The flow meter option adjusts dosing based on flow rate, ensuring efficient chemical usage and cost-effectiveness.
Efficient Water Treatment: PAC injection enhances the coagulation process, accelerating the settlement of suspended solids, resulting in faster and more effective water treatment.
Minimal Manual Intervention: The automated system, coupled with solar power, allows for continuous operation with little need for human oversight, reducing labour costs and operational complexity.
Compliance with Environmental Standards: By effectively removing suspended solids and clarifying the water, the system helps meet strict environmental regulations for discharge or reuse.
Applications
Construction Sites
Treating runoff water and sediment-laden flows before discharge into natural water bodies or stormwater systems.
Stormwater Management
Managing and treating stormwater that may carry pollutants or suspended solids from urban environments, particularly in remote or off-grid areas.
Why Choose a Solar-Powered DoseBox
The solar-powered DoseBox chemical injection system, equipped with flow control options through either a flow switch or flow meter, offers an efficient, automated solution for treating dirty water with PAC. Its sustainable, remote-operating capabilities make it ideal for improving water clarity on construction sites, industrial facilities, and stormwater management systems. The result is cleaner water that meets environmental standards while minimizing operational costs and reliance on electrical infrastructure.
