Overview
Bio fouling (or biological fouling) is the accumulation of microorganisms, plants, algae, or animals on wetted surfaces. Ajman Municipality, Environment Department, Natural Resources Conservation Section, had installed six water quality monitoring stations. ELARD served as the integrator for monitoring creeks and water surfaces in the city of Ajman, United Arab Emirates, and consistently checked for water pollution and challenging environmental variables.
ELARD is a supplier of Solinst Eureka quality probes and had supplied, installed, and maintained many similar projects around the Middle East Area.
Challenge:
ELARD faced a myriad of problems to maintain and operate the water quality monitoring stations due to the extensive growth of biological organisms on water probes and the harsh environment.
Elard, UAE – United Arib Emirates
Solution:
ELARD adopted a series of measures to solve problems related with bio fouling and reduce the growth of biological organisms on instruments. ELARD used Eureka Manta 3.5 Probes with Sutron GPRS Link Datalogger. Measured parameters included: PH, Dissolved Oxygen, Temperature, Conductivity, Salinity, Total Dissolved Solids, Refined Oil, Turbidity, and Chlorophyll.
In addition to making a proper site visit (essential for any long-term monitoring system,) ELARD used:
- Copper mesh: copper-gauze anti-fouling kits; 5″ x 30″. ELARD used Eureka supplied copper mesh around the sensor guard to avoid strong growth on the sensors which could eat up the epoxy of the sensor body.
- Duct Tape & Packing Tape: purchased from local shops. This protected the probe body and helped clean the equipment quicker. (It is recommended using proper safety tools while performing the task.)
Result:
The probes, equipped with anti-fouling components, performed well over a 30-day deployment, without any signs of bio fouling accumulation on sensors and drift in values. This helped reduce site visits, increased the life of sensors, and the equipment was cleaned more efficiently.
Manta Series Water Quality Probes
Solinst Eureka offers the largest selection of water quality sensor technologies in the industry. So in addition to standard configurations, each probe may be customized for your specific application. Pick sensors of your choice to fully populate larger probes, or add a battery pack to convert a probe to a logging device.
Manta Trimeter Water Quality Probe
The Trimeter holds any one sensor* from the Sensor Parameters list, Plus temperature and depth sensors (both are optional). For example, a Trimeter configuration could be turbidity, temperature, and depth. Another example could be DO and temperature.
EasyProbe: Water Quality Sondes
The EasyProbe, by Solinst Eureka, is a high-performance, cost-effective water quality monitor. It's ideal for spot-checking, remote telemetry, education, research, aquaculture, and more. The EasyProbe20 includes sensors for temperature, dissolved oxygen, conductivity, and pH, while the EasyProbe30 adds a turbidity sensor. Eureka multiprobes are known for their reliability, with a three-year warranty covering all sensors, and have the lowest maintenance costs in the industry.

Water Level, Temperature & Conductivity Datalogging
The Levelogger 5 LTC measures and logs water level fluctuations, temperature and conductivity. It is programmed to record at intervals as often as 2 seconds. It includes an 8-year battery, memory for 100,000 sets of readings, and comes in 6 pressure ranges. A PFAS-free coating (inside and out) provides superior corrosion and abrasion resistance.
TLC Meter – Measure Accurate Temperature, Level & Conductivity
A TLC Meter provides accurate, stable temperature and conductivity measurements, displayed on a convenient LCD display for easy reading. Static water level and depth of readings are read off Solinst flat tape, which is precisely laser-marked every mm or 1/100 ft. Tape lengths are available to 300 m (1000 ft).
