Yes, I found this for you. https://www.iwapublishing.com/news/distillation-treatment-and-removal-contaminants-drinking-water

But I have heard drinking distilled water may not be that healthy, as desirable nutrients are removed, and the ultra pure water can remove nutrients from the body. Eat healthy and take vitamins to compensate.

Well,

99.9% the distilled water is of H2O Molecules

Yes. Solar water distillation removes Arsenic.

there are plenty of good literature. please see the links below for more information.

good luck for your studies.

William F. Hansen , blending is one option to overcome this (well, in some cases).

Portable water can not be used from distlination .... Solar distilled water is pure without mineral

Good question I will follow answer

I prefer to proof that in laboratory scale bench.

Hello Sudip,

If you are referring to simple passive solar distillation, the answer is Yes. Please see: https://www.researchgate.net/profile/Shivakshi_Jasrotia_R/publication/268519813/inline/jsViewer/5c2f26e492851c22a358895a and https://revistas.javeriana.edu.co/index.php/iyu/article/view/18971

Yes. Solar water distillation removes Arsenic. useful link:

Dear Sir Mr. Mark Brotman,

Thanks for your response. Solar distillation is also useful.

Solar distillation can remove Arsinic from water if not you can proceed to a bidistillation

Valuable contributions.

thank you Sir

Yes, double distillation can be a solution.

Interesting...

Hello,

According to the principle of distillation that chemicals vaporize at different temperatures and most potential chemical contaminants in drinking water have vaporization points higher than water. Therefore, untreated water is heated in a solar distiller; pure water vaporizes first without contaminants. I think the method is suitable for removing Arsenic from water.

This method of purification is also with both pros and cons.

Solar distillation is useful so far UV light can remove it. It contains rays that can break hydrogen bond of water which will reduce or remove arsenic cos is part of minerals that water contain.

Solar distillation is also useful.

Yes, it does

Hello Sudip, good question. I often analyze arsenic in natural waters for mineral exploration. In highly anomalous arsenic areas, these values are abrogated downstream of ponds, so I normally discard such downstream values as being irrelevant to targeting aims. This I find particularly so in moderately deep ponds with algae growths. Shallow ponds, even with plenty benthic algae, depending on the flow rate, will spill arsenic laden waters downstream of highly anomalous As waters upstream.

Both algae and bacteria reduce arsenic levels. But I have noted in algal rich ponds arsenic can go down to ppb level downstream of highly anomalous arsenic streams mitigated with such ponds, so I guess a first pass with algae is important and benthic binding sediments second. How much of this is pond activity is due to Iron reducing bacteria compared to algae is a mute point. Nevertheless I'm sure there will also be a pelagic zone of such bacteria in deep ponds that adds effect as well.

Such Iron reducing bacteria can also be harnessed in an activated sandy fluid bed to very effectively remove arsenic, and this can be constructed for community or even home use if maintained. Fowling of the sediment is managed by back flow of the activated sandy bed of iron reducing bacteria and this can be automated.

It can be considered since evaporation may vary in efficiency and output throughout the year.

Algae mats can also be considered along with simpler Iron pellet beds and activated carbon beds, partially and variably effective.

From my experience above, for larger scales of ground water treatment , I would recommend an isolated from environment and pathogen pond. Just enough non pathogenic nutrient to suffice algae arsenic entrapment to sediment would be ideal. However this still introduces some organic bound metal to clarify. Also throughflow retention times become important to sediment the arsenic. The advantage though is that the system can be modified in scale to community needs.

If such ponds are subject to aerial pollution, extreme in many regions of the world today, additional phytoremediation plants could be considered and a sub aerial drainage system with secondary isolated pond or water retention facility installed. This could be considered for home systems with adequate land available, though more ideal for joint community based systems. Complete isolation from near shallower surface ground waters that way be laden with pathogens would be mandatory.

I note you reference to other ions, sodium, pH etc so you may wish to adopt tertiary processing that handles both.

A gel system will remove arsenic, best with ligated iron and even more highly effective with Lanthanum ligate to activate such gels. Eluting the arsenic to rejuvenate the gel can be done but a complex process for home use with HCL, beyond domestic management. The home becomes a Lab, untenable if mistakes are made.

In terms of evaporation, note some metal(oid), including arsenic will be bound in organic gel colloidal form, indeed in some case the majority of it. This organic ligated metal can be effectively released with UV. However some organics may be volatile to distillation, and pass on the metal(oid) to distillate. This organic bound metal can be variably captured with activated carbon or gel. A ratio of bound to ionic solubility is introduced here in processing. Weather the bound metalloid to free metal ion ration is favorable needs experimentation through such systems, for each natural water and how each stage of treatment is sequenced may vary this ratio. If every bit of arsenic is to be removed consider multiple systems. If co metalloids such as selenium are also a problem (eg surface waters near coal fired power stations or alkaline ground waters, low sulphidation base metal associated gold deposits proximity where alkaline waters can carry very high arsenic in addition), this needs special attention. Example selenium being volatile if contemplating distillation. Reduction of labile ionic forms via bacteria is a strategy and can be implemented in upstream processes similar to arsenic.

Most high selenium is best removed as high ionic forms in particular are toxic.

However some organic selenium in diets is essential, Se being the 8th essential element for life. Moreover, data from toe nails and hair analyses show selenium abrogates effects of some cancer associated with arsenic (in the same data cohort). Trace selenium, (more likely organic forms), are essential.

All systems pitted against each other to compare the best combination of costs, effectiveness and utility for YOUR natural waters would be helpful, as waters vary a lot in chemical makeup. Your arsenic target reductions need some thought as well. Example remove as much as possible as cheap and easy as possible, or just remover the lot or anything in-between depending on cost and utility. Identify your target. That I suggest may needs some experimentation with your waters to conceive an optimal target you can be happy with. However easy good first pass reduction of arsenic is a priority in the first instance of implementation.

Ionic membranes are costly but new membranes (eg see data from Hatch), highly effective, especially for very complex problematic waters such as acid mine but also natural acid rock drainage waters. Even here I would recommend including upstream treatments such as ponding phytoremediation of waters beforehand, with both microscopic and macroscopic plants as it reduces load and costly maintenance.

I highly recommend considering adequate dietary selenium to abrogate arsenic cancer risks and folate. And B vitamin complexes to enhance metabolic repair mechanisms for arsenic toxicity in any community subject to chronic exposures of arsenic. Thinking about this is important even after water treatments since there are no safe limits for arsenic, including natural low level exposure over a lifetime.

Arsenic in water remains in organically bound and inorganically bound. In general, all inorganically bound arsenic compounds may not be evaporated like water, but organically bound As compounds in reducing condition may form volatile As compounds like, methyl arsine (AsCH3), dimethyl arsine(As (CH3)2, etc. and may be evaporated to contaminate the distillate.

Distilled Water Removes Minerals and Contaminants Distillation will not remove all the chemicals but removes soluble minerals (i.e., calcium, magnesium, and phosphorous) and dangerous heavy metals like lead, arsenic, and mercury. ... The vaporization process strips salt, metals, and biological threats.
