Our water source has been detected as contaminated by hydrocarbons (Total Petroleum Hydrocarbons broadly know as TPH). Is there any technology to help us controlling hydrocarbons in site, at the intake of a potable water station?
I have looked at the other responses you have recd and none of them have suggested Electro-coagulation which is the technology developed by my research company to deal with "Frac" water out of the oil field. This is a technology that utilizes consumable electrodes that we supply to you and we can maintain the system or train your personnel how to replace the electrodes. I have numerous articles on this technology on the internet. You can call me at 916-877-1553 to talk more about how to use this in your situation. When the oil is in the water the technology removes it with an electric current and the oil comes out looking like small pieces of pepper. We also remove up to 98% of the other contaminants in the water including metals.
We can provide you with different solutions by i.e. stripping and/or absorbing the hydrocarbon content out of the water. Should you be interested in a tailor made application, just contact me.
We have a product called Osorb Media that absorbs hydrocarbons from water. Our media is NSF certified for drinking water applications, and available in several different forms. We also have an industrial treatment system and are looking for pilot locations. Please reach out to me for more information. http://www.absmaterials.com/osorb-media.aspx Email: info@absmaterials.com

Removal of hydrocarbons can be done by oxidation (often forms byproducts in water), activated carbon (DIFFICULT TO REGEN), or organic polymers. Lanxess has an effective product lewatit AF 5 that should be evaluated for this application
Enviro Now are specialists in absorbents and adsorbents that remove hydrocarbons from aqueous solutions. Most of our solutions are simple as you can see if you wish to visit our website at; www.enviro-now.com I'm happy to work with you to resolve your issues.
If you successfully remove your bulk TPH from water and you still will need some improvement, you could use ozone, which will successfully polish the water and could make it cristal clear, remove any smell from it and disinfect it.
If you interested, I will be more that happy to assist or to answer any of your questions.

Treatment equipment to remove dispersed oil from water relies on one or more of the following principles:
Gravity separation (often with the addition of coalescing devices)
Gas flotation
Cyclonic separation
Filtration
Centrifuge separation
In applying these concepts, one must keep in mind the dispersion of large oil droplets to smaller ones and the coalescence of small droplets into larger ones, which takes place if energy is added to the system. The amount of energy added per unit time and the way in which it is added will determine whether dispersion or coalescence will take place.
The greater the difference in density between the oil droplet and the water phase, the greater the vertical velocity; that is, the lighter the crude, the easier it is to treat the water.
The higher the temperature, the lower the viscosity of the water and, thus, the greater the vertical velocity; that is, it is easier to treat the water at high temperatures than at low temperatures.
Small oil droplets contained in the water-continuous phase are subject to the competing forces of dispersion and coalescence. An oil droplet will break apart when kinetic-energy input is sufficient to overcome the surface energy between the single droplet and the two smaller droplets formed from it.
The greater the pressure drop (and, thus, the shear forces that the fluid experiences in a given time period), the smaller the oil droplets will be. Large pressure drops, which occur in small distances through chokes, control valves, and instruments, result in small oil droplets and water that is harder to treat.
Within water-treatment equipment, in which the energy input to the fluid is very small, the process of coalescence takes place; that is, small oil droplets collide and form bigger droplets. Because of the low energy input, these are not dispersed.
The Macro Porous Polymer Extraction (MPPE) Technology is a highly effective, fully automated, remote controlled and guaranteed method for removing dissolved and dispersed hydrocarbons from water with efficiencies of 99.9% down to below ppb levels.
The Macro Porous Polymer (MPP) acts as a carrier for nontoxic and biodegradable extraction media and absorbs and extracts hydrocarbons from water. The miniscule plastic spheres are capable of reducing contaminant concentrations in water by a factor of more than 1 million, which means that concentrations of thousands ppm (parts per million) can be lowered to below 1 ppb (parts per billion). This is done in only one cycle. The water purification provides clean water for recycling or discharging, and yields almost 100% pure hydrocarbons suitable for reuse. In the MPPE water treatment process, hydrocarbon-contaminated water is passed through a column packed with MPPE particles. The particles are porous polymer beads that contain a specific extraction liquid. The immobilised extraction liquid removes the hydrocarbon components from the process water. The purified water can either be reused or discharged.
If the quantity of HC in water is more then distillation process may be used. And in stripping section steam can be introduced direct and HC overhead product can be recover from top product, The reflux stream also given for mass transfer and purification.
Oil Free Hydrocarbon Removal Matrix (HRM)
The oil free technology is engineered to remove hydrocarbons from water instantly. Oil free immobilizes and permanently bonds the hydrocarbon compounds without developing pressure. The Oil free technology removes oily sheen, synthetic and natural oils, BTEX, PCB's, solvents and organically bound metals. The pressure drop across a saturated Oil free cartridge is less than 1 psi. Oil free technology is available in turn-key systems with operational ranges from 1 gpm - 5000 gpm.
Applications
Marine oily bilge water filtration and treatment
Protection of ultra filtration and nano filtration membranes from fouling
Process water recycle and reuse applications
Filtration of hydrocarbons from washing operations
Filtration of hydrocarbons from manholes and pits
Process/Produced water treatment
Filtration of hydrocarbons from compressor condensate
Filtration of hydrocarbons from tank farm runoff water
I am presuming that the contaminant is in the form of a thin viscuos film which will float on top of the water. There are oil skimers available. For higher contamination, the water will not be potable. Therefore you need to specify the contamination level first.
www.GlobalAdvantech.com We supply cost-effective water treatment and bioremediation systems using proven and proprietary technology. It may be possible to extract hydrocarbons. Systems are in ISO containers, are portable - unless a very large plant is required - and deal with the specific chemical analysis of the input water, the operational processes involved in each case, as well as the looking at the output requirements.
If you're interested, please contact me or respond on the website.
With the limited knowledge that I have I have an experience that Bioremediation is the best technology to remove TPH from whatever the source.It is cheap as well.let the source be bioremediated and so contaminant is taken care of right at the source.
If the TPH levels are high and if a large fraction of it is free oil, then this fraction can be removed and recovered by a coalescence separator. The remaining dissolved PH fraction can be removed by activated carbon (GAC filter) for small-medium scale applications. For large scale applications, medium-high levels of dissolved hydrocarbons can be removed by (advanced) activated sludge biological treatment,
As the colleagues are saying, there are many technologies avilable to remove TPH from water. However, depending on the origin of the pollution, results will be limited and efforts maximised. I strongly suggest you to provide a detailed explanation of the water source (groundwater?) delineate the origin of contaminats (local leakages or broader), water yield to be treated, etc.
