ONLINE MONITORING OF THE CITY'S WATER SUPPLY AND SEWAGE SYSTEMS
OUR GOAL
To return the water to nature after purification, the same as the water we take from it.
WHO IS THIS SOLUTION FOR
- Water utilities - to improve the reliability of water supply and sewage systems.
- Cities and communities - to protect drinking water sources and environmental safety.
AUTOMATIC EARLY WARNING STATIONS
Automatic early warning stations at water intakes are a key tool for protecting public health.
They detect danger at early stages, when large-scale consequences can still be prevented.
Appointment.
Warning of increased water toxicity as a result:
- Pesticides, pathogens and other toxic substances entering the water;
- man-made accidents at treatment plants and industrial enterprises;
- terrorist acts with the use of chemical warfare agents
Main functions
- Identification of the causes of increased water toxicity at water intakes;
- Sampling with an automatic sampler for in-depth physicochemical analysis of water after receiving
signal about the toxicity of the sample; - Automatic monitoring of water indicators that may affect toxicity alarms and risks to the public.
COMMON INDICATORS OF AUTOMATIC WATER MONITORING
- dissolved oxygen
- suspended solids
- water mineralization
- sulfates
- chlorides
- ammonium nitrogen
- nitrates
- nitrites
- phosphates
- oil products
- biochemical oxygen demand (BOD5)
- chemical oxygen demand (COD)
- dissolved organic carbon
- water toxicity (based on biotesting)
- bacteriological contamination
- level of radioactive contamination
- hydrogen index (pH)
- temperature
- algae
Existing technologies for determining toxicity:
- Chemical analyzers detect only specific substances
- Biomonitors determine the presence of a toxic substance without determining its type - comprehensive indication
Uniqueness of the indicator Toxicity monitoring based on a toxicity biomonitor is precisely the identification of a toxic event at early stages, followed by the determination of a specific toxic substance using chemical and/or other methods. The most advanced version of the toxicity biomonitor is the DaphniaToximeter II analyzer manufactured by bbe Moldaenke.
Automatic biomonitors are used for early warning systems for emergencies and terrorist attacks.
Daphnia Toximeter II
A biological early warning system based on daphnia with video assessment and computer control.
The BBE DaphniaToximeter II monitors water for toxic substances using daphnia (Daphnia Magna) in a continuous flow of water sample.
A CCD camera records the behavior of daphnia in a flow cell with a water sample flow.
The behavior of the daphnia is evaluated using internal software. Statistically significant changes in the behavior of the test objects signal the presence of toxic substances in the water, which is immediately displayed on the screen of the device. The device can be controlled and monitored remotely.

Regulatory documents of Ukraine on surface water monitoring
- According to the Order of the Ministry of Environmental Protection of Ukraine (MEP) «On Unified Interagency Guidelines for Organizing and Implementing State Water Monitoring» No. 485 of 24.12.2001, the monitoring is carried out for surface and sea waters, coastal zones of reservoirs, groundwater and sources of water pollution.
- According to the CMU Resolution «On Approval of the Procedure for State Water Monitoring» of July 20, 1996, No. 815: in order to obtain systematic information on water quality. The State Agency of Water Resources and water supply and sewerage enterprises monitor water quality in the areas of drinking water intake by chemical and biological indicators.
- In the areas of water bodies where cases of high pollution (HP) and extremely high pollution (EHP) are observed from time to time, as well as in border areas, it is advisable to create automated systems for monitoring the quality of natural waters in accordance with DSTU 3831-98 «Environmental Protection. Automated systems of natural water quality control. Types and basic requirements».
