Attachments will show composition of hydrocarbon (DCP-Goldsmith East LACT #7415).

Also you will find sketches to show details of the system.

We have a water stream from a 3 phase separator (see attached “East LACT Tk Instr & Controls“) and have a very low tolerance for entrained hydrocarbons. The max limit of hydrocarbons in the water is 50mg/L.

The associated hydrocarbon is shown on attached DCP-Goldsmith East LACT #7415.

I would like to get some info on filtration systems as applied to this process.

1. Can you filter the hydrocarbon to achieve the 50mg/L limitation (or lower)?
    
2. Can the filters be regenerated or do that need to be replaced when saturated?
    
3. How can we determine when the filters are at their limit and need to be regenerated or replaced?
    
4. Do you furnish equipment mounted on a skid with parallel filters including controls and instrumentation to alert operations if/when their actions are required?
    
5. Can you give me a ball park figure on cost for this system and cost of replacement filters?
    
6. The system should be sized for 50 GPM flow rate at a pressure of 75PSIG. Temperature will range from 60F up to 100F.

If you believe you can help this gentleman out, please drop us a line w/ your contact information and we will forward it on to him.

Moral of the story?

In a perfect world we would have all the answers to every water quality question anyone ever asked us… but the fact that we all have to (or should!) worry about the quality of the water we drink proves that we do not live in a perfect world so we do the smart thing and reach out others we know who may have the answers our readers seek.

If you, as homeowner, business owner, or experienced water quality professional have a question about water quality, don’t hesitate to ask because the more knowledge you have, and we all share, the greater the odds of our collectively coming up with solutions to the world’s constantly growing number of water quality issues.

Does anyone make a big blue oil filter?

As a matter of fact, a company by the name of Pentek manufactures a product called the Pentek OAC-20BB Oil Absorbing Filter which fits conveniently in a standard 20 inch Big Blue housing.

The Pentek OAC-20BB Oil Absorbing Filter uses a modified cellulose-based filter that attracts and chemically bonds with specific hydrocarbons and pollutants such as dissolved oils in water. This filter cartridge also has the part number 155596-03 associated with it.

This product provides instant absorption of up to 90% of total hydrocarbons in a single pass, can operate at high flow rates, result in low pressure drop, and can hold 250% to 300% of its own weight in hydrocarbons.

Where might the Pentek OAC-20BB Oil Absorbing Filter come in handy?

This filter would benefit anyone wishing to remove oils and hydrocarbons from water. Examples of locations where one might expect to find hydrocarbons in water include:

• Around gas and oil facilities
• Bilge water entering/exiting ships
• Surface/Rain water runoff from truck stops, airports, parking lots, major roadways, etc.
• Near automobile/truck service & repair shops
• In areas near machine shops
• Regions surrounding facilities housing industrial processes
• Runoff from car and truck wash bays

Specifications of the Pentek OAC-20BB Filter

• Overall Dimensions of 20″ x 4.5″
• Inner Core Diameter of 1.110″
• Rated for a Max Temp of 125 F
• Rated for a Flow Rate of 5 to 10 GPM
• Pressure Drop Range of 0.2 to 1.0 psi

With all the talk about oil washing up on the shores as a result of the BP oil platform disaster, some people have started to ask a very smart question:

Could some of that oil somehow end up in my well water if I live close to the shore?

At this point no one can answer that question definitively, but rest assured plenty of people would prefer to err on the side of caution and have a water filter system capable of removing any trace elements of the BP disaster that may find their way into their water supply.

The Crystal Quest Mega Triple Undersink Water Filter, known by manufacturer’s part number CQE-US-00309 and good for proper filtering of up to 10,000 gallons of drinking water, uses a combination of three separate filter chambers:

1. Water flows through a sediment filter cartridge that removes sediment, silt, sand and dirt. This helps to extend the life of water softener and water filters and prevent damage to control valves and/or pumps.
2. In the second filter chamber, water flows through pre one – micron filter pads which remove suspended particles such as silt, sediment, cyst (Giardia, Cryptosporidium), sand, rust, dirt, and other undissolved matter.

   It then flows through a bed of media made of a special high-purity alloy blend of two dissimilar metals — copper and zinc (Eagle Redox Alloy® 6500 and Eagle Redox Alloy® 9500) — that works using electro-chemical and spontaneous-oxidation-reduction (REDOX) principles. At this stage chlorine gets instantaneously and almost inexhaustibly oxidized iron and hydrogen sulfide get oxidized into insoluble matter which attaches to the filter media, heavy metals such as lead, mercury, copper, nickel, chromium, cadmium, aluminum, and other dissolved metals also get removed by the electrochemical process.

   In the next stage, water flows through the ion exchange resin, further reducing heavy metals such as lead, copper, aluminum, and water hardness.

   Next, water passes through granulated activated carbon (GAC), a compound universally recognized and widely used as an effective adsorbent for a wide variety of organic contaminants such as chlorine (99.9%), chemicals linked to cancer such as THM’s and benzine, pesticides, herbicides, insecticides, volatile organic compounds (VOC’s), PCB’s, MTBE’s and hundreds of other chemical contaminants potentially found in drinking water. It also works to greatly reduce and/or eliminate bad taste and odors in drinking water.

   The last section of this filter chamber contains another one-micron filtration pad for further reduction of undesirable particles.

3. In the third filtration chamber water travel through a solid carbon cartridge designed to remove remaining volatile organic carbon compounds (VOC’s), insecticides, pesticides and industrial solvents.
