Monitoring Buoy

How it works

Monitor

1. Monitor

Monitoring Buoy provides a complete overview of the water quality by collecting the following parameters every 10 minutes: Chlorophyll α (green algae) Phycocyanin (blue-green algae) pH Turbidity Dissolved Oxygen Temperature Additional sensors sets can be implemented.

Predict

2. User friendly software

The collected data is delivered in real-time via 3G/4G to the user friendly web-based software MPC-View. The software allows you to set up specific automatic alarms to inform about changing algae and/or water parameters, or maintenance activities.

Control

3. Predict algal blooms

The algorithm developed in cooperation with research institutes allows you to predict algal blooms 3-10 days in advance.

Maintenance

Installation and maintenance

The system is easily deployable and anchored in the lake or reservoir. It uses solar panels to provide power, all year round in any country.

Our water quality sensors are equipped with a wiper mechanism for automatic cleaning of the sensors after each reading, keeping the maintenance to a minimum and the readings accurate.

MPC-View Water quality monitoring software

Overview

MPC-View is an advanced web-based water quality monitoring software. The software allows to generate a complete overview of the water quality of one or multiple water bodies.

  • Web-based software
  • User friendly

Visual insights

The software provides insights into the water quality, algae trends, and progress of the ultrasonic treatment in the lake or reservoir.

Dashboard

Users can log in to the software, where they can find a personal dashboard with an overview of the water quality and MPC-Buoy system status.

Real-time alarms

The software allows users to set up specific alarms to inform about changing parameters. Users receive an e-mail notification when the alarm goes off.

87% algae reduction to improve drinking water

The country’s most important water source After years of struggle with algal blooms, The Santo Domingo Water and Sewage Corporation (CAASD) installed multiple MPC-Buoy systems to cover the 7km²/2.7mi² Valdesia reservoir. The first results were visible after two weeks, and the project exceeded the targets for the first year with a 87% reduction in algae levels. The Valdesia reservoir is the main drinking water supply for the population of the…

Lakes remain open during algae season

Control Cyanobacteria concentration Four solar-powered algae control systems were installed in the Aquadrome in Rickmansworth (UK) to control the cyanobacteria concentration in two lakes. Two systems were installed in a lake used for water skiing and fishing, and two additional unites were installed in June 2017 in a lake used for sailing. To ensure that the concentration of cyanobacteria remained at an acceptable level at a popular public open space…

Reduced blue-green algae counts in New Zealand

Reducing blue-green algae counts In the Lower Nihotupu Dam in Auckland, New Zealand, five solar-powered algae control systems are controlling blue-green algae blooms. The project started in December 2016 and it proved to be a great success. The algae counts have significantly decreased over the summer, as compared to the previous year. The water utility’s main objective was to reduce blue-green algae counts in a dam used as a water…
