LEAKWISE - IONICS

Oil on Water Detection and Monitoring Systems

For contamination detection, measurement and control systems.
The Leakwise floating sensors measure the difference in absorption rates of high
frequency electromagnetic energy between hydrocarbons
(and other organic solvents) and water.

Unlike optical and traditional electric conductivity and capacitance detection, this
technology enables reliable detection regardless of level changes, waves,
process upsets, oil & dirt coating, changes in water temperature, salinity, etc.
The Leakwise detection systems are unique in their capability to detect the
presence of very small layers of contaminating hydrocarbons starting from 0.3
mm, and to continuously monitor the growing thickness of these layers. 

The LEAKWISE® ID-221 is installed in sumps
and in groundwater monitoring wells to detect
floating oil sheens resulting from leaking
underground storage tanks and pipe-lines. It is
also used to monitor hydrocarbons and other
organic solvents during site assessment and
remediation. 

ADDITIONAL APPLICATIONS are in detecting
and monitoring floating hydrocarbons in: sewer
systems, waste water treatment systems,
oil/water separators, cooling water trenches and canals, storm water run-offs,
retention ponds and sumps, boiler condensate tanks etc. 

The LEAKWISE® ID-223 can be installed in dry
sumps to detect oil leakage or spillage from:
above-ground oil storage tanks in tank farms,
to detect oil leaks from transformers in sumps
at power distribution substations, etc. It can
also be used to monitor waste water discharge
after treatment. 

ADDITIONAL APPLICATIONS are in
detecting and monitoring floating
hydrocarbons in: sewer systems, oil/water separators, cooling water trenches
and canals, storm water run-offs,
retention ponds, boiler condensate tanks,
groundwater remediation system etc. 

APPLICATION 1: REMEDIATION CONTROL
Inserting the ID-225 in groundwater monitoring wells enables one to:
Plot changes in oil thickness over time to enable more effective choice of
oil skimming wells. 
Monitor effectiveness of remediation techniques 
Implement automatic on/off control of the remediation techniques. 

APPLICATION 2: SKIM TANKS
In many processes, a skim tank is used to collect
entrained oil in waste water. The ID-225 is inserted into a tank through
 one of the inspection hatches, enabling one to:
Automatically start and stop the top skimming operation. 

APPLICATION 3: MONITORING 011/WATER
SEPARATORS
Environmental regulations require oil/water separators to be covered. An
ID-225 can monitor the thickness of the oil layer build-up in the separator. 

APPLICATIONS:
The AGAR ID-227 is designed to be installed off-shore near oil tanker buoy
terminals, jetties, piers in order to detect floating oil sheens resulting from
spills or leaks which may occur during the loading/discharge process. 

ADDITIONAL APPLICATIONS are in detecting and monitoring floating
hydrocarbons near off-shore oil rigs and in: lagoons, lakes, rivers, open
channels, large retention ponds etc. 

DSP-220 APPLICATIONS


The DSP-220 is a computerized monitoring and data acquisition system, especially
designed to support multiple LEAKWISE® and other specialized sensors. The system can
 be tailored to a particular application by using a combination of units and their options.
The basic unit (BDSP-220) includes a microcontroller, data acquisition hardware for 8
sensors, a panel with status lights, a keypad and display, and a serial communication
channel. Operator interaction is carried out via the keypad and display through a series
of simple, user friendly menus. Status of all sensors, or of a selected sensor,
 is seen on the display in measurement mode.
Configuration and calibration modes are used for system setup and
optimization, and are accessed only by an authorized operator. 

OUTPUTS OF THE SYSTEM INCLUDE:
Communication channel for periodic status data flow. 
Optional data logging is used when a connection to the communication
channel cannot be used as a permanent installation. 
Optional modem interface, including automatic dial-up, for long distance alarm. 
Optional relays, each one can be assigned to a specified sensor, and will
activate when an assigned set point is exceeded.
This feature can be used for control purposes. 
Optional 4-2OmA output channels, each one can be assigned to a
specified sensor and give a continuous output related to the
measurement of that sensor.
