The only way I can think is that the C as activated charcoal is used as a filter. The activated charcoal will absorb certain impurities helping to clean the water

Nanostructured Carbon Water Filter. It#39;s 350 times higher adsorption effect than GAC \ Granular Activated Carbon.

Filtracite is manufactured from highly durable anthracite, which following extraction by mining is screened, washed and processed to produce a comprehensive range of water filtration products.
The physical and chemical inert nature of Filtracite makes it suitable for all potable, municipal and industrial processes where the removal of finely divided particulate material from aqueous suspension is required.
Microporous activated anthracite is produced from waste anthracite powders by the conventional steam activation. The activated anthracite is also treated by supercritical water reaction (SWR) by using distilled water and hydrogen peroxide solution as a liquid medium for SWR treatment. It has been found that SWR treatment can improve the mesoporosity of the activated anthracite though the micropore volume was reduced by the treatment. In liquid-phase adsorption and supercritical water regeneration studies, phenol and organic dye RED 31 were selected as the representative adsorbates. The adsorption and regeneration characteristics of activated anthracite were compared with those of a commercial activated carbon. The results indicate that the activated anthracite prepared showed comparable phenol adsorption capacity but significantly lower dye adsorption capacity than the commercial one. However, supercritical water regeneration efficiency was remarkably high. The first/second regeneration efficiencies of commercial activated carbon and activated anthracite exhausted with phenol were 55/55 and 65/65%, respectively, and in the case of RED 31, 78/79 and 338/317%, respectively, with losses of activated carbon less than 4% per regeneration. Because of little loss of activated carbon during successive regenerations, this SWR regeneration method was suitable for regenerating spent activated carbon or anthracite

I have a new well installed in limestone. There is a strong sulpher odor and the water turns black after it sits for awhile in tank. I am using the water ONLY for lawn watering and to refill my koi pond - so no chlorine treatments. I saw greensand filters and carbon treatment, but gees it is a lawn and a pond and those treatments are very expensive!. The holding tank is pressurized. Would any type of aeration work? I don't care so much about the lawn but the sulpher probably isn't good for the koi.

What about making ur own carbon filter to bo between the water source and the holding tank?

Here's how...Walmart sells a big bag of activated charcoal for really cheap. What you could do is make an enclosure for this using 4 inch Schedule 40 PVC plumbing pipe with 2 end caps.

PVC glue will hold the end caps, and you'll need to drill thru the end caps and make water tite fittings and correct connections.

make the 4 inch pipe about 12 inches long and fill it up full with the activated carbon,

USe Duct tape to hold the carbon on one of the ends while u keep the pipe standing up, then fill it completely*** on both ends of the end caps...Use Epoxy Glue to secure in a 4 pieces of cut round fine mesh Fiberglas Screen material from Home Depot or LOWES on the inside then

Before closing the ends do the top end first. Once it is glued n secure
Turn the pipe filter upside down, careful not to damage ur pipe connection then remove the duct tape that was holding the carbon and glue on the last end with the PVC glue.

To use PVC glue, it has to be fast...so here's what you do in a well ventilated area, with newspaper or large tarp covering a floor, and try not to breathe the glue fumes...open the PVC glue and brush lots of the glue on the the outside of the pipe where the edge is, Dont worry about using too much, you then have to brush the inside of the end caps, hopefully u have at least 3/4 inch space for glue all around the inside of the end cap.
Then press the 2 glued pieces together as far as u can. It will setup in seconds and should not be used for at least 2 hours.

When u epoxied that screen material inside the end caps that is for keeping the carbon from flowing out into ur tank. If you could add in a round piece of Tshirt cotton on the closest side of the carbon, this will help keep the black dust of the carbon from fouling ur tank.

...... mark a date on the outside of the pipe when u made it, then 1 year later you'll have to replace the whole thing.

wow nice project. any questions?

I think the biggest challenge will be making the connections on both end caps. You drill holes for the connectors that match up to ur pipes.
how do u make water tite seals? U'll have to use Permatex Yellow Seal, which u can find in a small tube at Autozone or other car parts store.

Use Teflon PASTE on the connection threads to prevent leaks.
this paste is avail in a squeezable tube from Home depot or Lowes, and squeeze the tube a lot gently to be sure the paste is well mixed inside.

I do not want to throw away water i used in washing (rinsing) clothes or the dishes. But I'm afraid my plants will die if I water them with water with traces of detergent. Is there a way of treating the used water at home without the expensive mechanical water treatments? I read activated carbon can remove some, but not all chemicals from water.

the only plants to avoid with gray water is brand new little seedling plants... they're not able to use it like mature plants are.......water from dishes is okay if the soap you use is NOT antibacterial.... and almost all laundry soaps these days are phosphate-free, so also safe for the garden... and yes, it will kill some bugs if sprayed rather than just run onto the ground...(and of course, no bleach water out there!)....... problem is, some municipalities don't allow the use of this 'gray water' due to it's bacterial content.... and they will fine you if it's not allowed and you're found out....call and ask....

if you don't care, then know that the bacteria thing is REAL, so never try to 'save' the water... if you're going to use it, use it immediately....

during our drought I ran a hose from my washer to a kiddie pool outside, then used a pond pump in it to move water thru the hose to the garden.... worked out right nice, too!....

don't forget to save the water that runs until it gets hot... keep a bucket handy to catch that water, too!....
keep one in the shower with you, as well... amazing how much you can catch there!.... don't dump the bathwater right away, scoop out a bucket and use it to flush with.... use the cooled potato cooking water for the garden, too... same with any other veggies you cook in water... boiled egg water, too... lots of good water gets wasted if you think about it....

We are setting up a Water Treatment Plant in Goa, for which we need to know the "Total Organic Carbon" (TOC) in the ground water (bore well). We need to find out the laboratory which does this test. We have tried to find but most of laboratories are not doing TOC test. We need to know the address of laboratory who can perform this test.

You can try with ONGC's Institute of Petroleum Safety,Health and Environment Management (IPSHEM),Betul,PO Velim South Goa -403723.I hope it will help.
