The Solinst model 102 is designed to measure groundwater levels, especially in small diameter tubes and piezometers or where a flexible cable is needed to snake past an in-well pump.

The cable has a heavy-duty jacket and stainless steel coaxial conductors for strength.
Permanent markings are precisely laser etched on the cable every millimeter.

Operation principles :

The model 102 water level meters uses a choice of 2 small diameter designs, attached to a narrow coaxial cable, fitted on a sturdy ergonomically designed reel.

A standard 9 volts battery housed in an easy-access battery drawer; power the water level meter.
When the probe enters water the electrical circuit is completed, sending a signal back to the reel where light and clearly audible buzzers are activated.

The water level is the determined by taking a reading directly from the cable at the top of the well casing or borehole.

A sensivity control allows the buzzer to be turned off while in cascading water and ensures a clear signal in both high and low conductivity conditions.

Especially designed for air and water treatment on contaminated site, the double phases extraction unit allows to pump air, water and free hydrocarbon phase from contaminated underground site in order to treat all phases separately.

Air pumped is run to an active carbon filter to discharge hydrocarbon compounds before release to the atmosphere and water is directly send to a stripper for treatment.

Description of a Venting Unit:

Completely automatic, the venting unit is generally supplied as follow :

Vaccum pump: The vaccum pump allows to depressurize the well or site (down to 990 mbar with an air flow rate from 100 to 600 m3/h). The air flow rate of the pump should be in perfect adequation with the site configuration (number of wells, distance between wells to the treatment unit).

Discharge pump: Pumps the water from the bottom of the vaccum tank separator and send to a stripping unit for treatment.

Condensate Separator tank: The condensate separator tank allows to separate water from air (misteliminator and Vortex effect). The air is after treated by active carbon filter and the water is directly pumped for treatment on stripping unit.

Control Panel: allows the control all electricals equipments in the unit (pump, level probes, compressor, pressure…). Possibility to remove information on PV via modem or external installation.

Ideal for low flow rate and where local installation is small or not very flexible.

Advantages :

• Model weight light, small and very easy to install for water treatment, Flow rate is < 5 m³/h
• Steel active carbon filter with « Epoxy » coating internal/external.

Conception design and construction of mobile water treatment units

Applications :

• Industrial water treatment
• Environmental applications ( phyto, hydrocarbons, etc)

Field of activities :

• Industrial skimmers (Oil/water skimmers, etc…)

Especially designed for air treatment in contaminated site, the venting unit allows to pump saturated air from contaminated soil in order to treat it. Air pumped is run to an active carbon filter to discharge hydrocarbon compounds before release to the atmosphere.

Description of a Venting Unit :

Completely automatic, the venting unit is generally supplied as follow:

• Compressor : allows to depressurize the well or site (down to 400 mbar with an air flow rate from 100 to 1200m3/h). The air flow rate of the pump should be in perfect adequation with the site configuration (number of wells, distance between wells to the treatment unit).

• Discharge pump : Pumps the condensate water from the bottom of the condensate separator for treatment.

• Condensate separator tank : allows to separate water from air (mist-eliminator and Vortex effect). The air is after treated by active carbon filter and the water falls down by gravity at the bottom of the tank.
• Control panel : allows the control of all electricals equipments in the unit (pump, level probes, compressor, pressure…). Possibility to remove information on PC via modem or external installation.

Especially designed for underground and surface water treatment, the monocellular SS Stripper allows the elimination of volatile hydrocarbon dissolved in water such as Solvent, BTEX, COV, COHV, up to 95 to 99% of efficiency (depending of the product and water characteristics).
Maximum flow rate of SS Stripper: 30 m³/h.

Description of the SS Striper

Fully made in Stainless steel, the SS Striper is supplied with the following equipments:

• Standard strippers are supplied with 3 stages :
Depending of the flow rate and efficiency required, different stages can be provided.
From the top of the stripper, the water comes in and passes through the stages which are opening to allow the air to be in contact with the water and to bubble the water at each level of
stages. The opening of stages is designed to get a perfect contact between air and water in order to get the best efficiency. The treated water at the bottom tank is pumped by a transfer pump. The contaminated Air is cleaned with Air active carbon filter.

• Air blower: Source of the air diffusion through the stages in the stripper. The flow rate of the blower depends of the flow rate of the water to treat.

• Pump: to pump the treated water at the bottom of the stripper
to send it to an active carbon filter. The pump is regulated by 3 level probes.

• Panel control: Control of electrical equipments on the unit:
pump, level probes, blower, pressure, etc. Transfer information on PC via modem or external installations on option.

Description :

Automatic air powered pumps offer exceptional capabilities in severe pumping conditions found in many landfill sites. Able to function in 2’’,3’’ and 4’’ wells and larger, this controlerless pump works without any bubblers, external control or bleeders. ATEX Certification.

Operation :

As the pump fills, an internal float rises until it comes in contact with the upper mechanism which simultaneously opens an air poppet valve and closes an air exhaust poppet valve. As the result, air pressure builds up within the pump body and displaces the fluid contents up and out of the pump through a discharge check valve.

As the discharge cycle progresses, the float falls and comes in contact with the lower stop that triggers the lever/valve assembly again.

Closing the air in poppet and opening the air exhaust poppet. The pressurized air the exhausts and the pumps is allowed to refill itself, thus beginning a new cycle.

How it works:

The RSS Skimmer is mounted at the top of the SPP-2 pneumatic pump.
The hydrocarbon catched by the membrane is going down by gravity inside the SPP-2 pump. When the SPP-2 is full, the internal float open the air compressed and discharge the product to the surface. Then the pneumatic active skimmer can cycle again. Fully automatic, the SPP-2/RSS can recover products 30 meters depth and inside a 50 mm (I.D) piezometer.
Skimming accuracy: The sheen.

Technical benefits:

• No parts in movement – The length of the membrane could be modify on demand
• Low maintenance and air consumption.
• Very High skimming accuracy.
• Simple to install.
• Atex Certified
• Hydrocarbon must be light (without particules) and not too much degraded.
