Dear Jonas Nyman, that it is a chemical agent not growing in nature like vegetables ( okra, cactus, Moringa oliefera,.......). That it has a relation to Alzheimer disease when aluminum residuals exceed some predefined limit. Please refer to the link:-

Is that enough Sir?
Alum is a common naturally occurring mineral. There is nothing unnatural about it. It is however, as you correctly point out, not a plant.
Regarding Alzheimer's disease and aluminium, I think you should be more careful with how you consult the scientific literature. The reference you gave, and the references in it, are not up to standard.
You see sir , the reference I gave is from a peer reviewed journal, also the publisher is SPRINGER and it is difficult to say that this reference and the references in it are not up to standard. Let me ask you a simple question. In your opinion what is that standard ? but please refer to an environmental law or legislations like from EPA or WHO. So that I can handle this standard. For your knowledge the above journal is (Thomson Reuters) and (Scopus) classified. Best regards.
just reading the abstract it seems the range in residual turbidity after treatment is unacceptably high for cactus extract compared to alum, which is a problem for modern treatment requirements as turbidity is a key indicator of treatment efficiency and risk factors. Might have a role in pre treatment with alum polishing afterwards though.
There is no connection between Alzheimer's and drinking water treated with aluminium salts.
Dear Henrik Rasmos Anderson , please refer to the following file which is one of the most important articles that assure the relation between alum and Alzheimers disease. I highlighted the sentence concerning alum(aluminum sulfate). Also I provided the link
to the article below . This is one of many articles concerning residual aluminum salts in drinking water. If you need more I am completely ready to provide you with a list.

Dear David Thomas Roberts , my advice is that you preferably read the article completely before judging, As there were 12 points concerning 12 months and the range for residual turbidity was (0.0-296) (ntu). So what about 0.0?? Yes alum has a higher efficiency than cactus and this was reported in the abstract .
Dear Nabeel Hameed Al-Saati,
The publication (Miller et al, 2008) you refer to is a fine paper about coagulation but as I search the .pdf it seems it doesn't contain the word Alzheimer's. Is it possible you meant to refer to another paper?

Dear Henrik Rasmus Andersen, the article says cleary that aluminum residual has an impact on human health this means many diseases not only one. Please refer to this article in the file. It discusses the relation with Alzheimer's disease.
Actually your article states some connection between aluminium in occurring in the brain and neurological disorders. "Many scientific articles are available,covering various aspects aluminum toxicity like the pathophysiology of neurodegenerative disorders (amyotrophic lateral sclerosis, Parkinson dementia, Alzheimer’s disease)." These conditions are caused by other physiological disorders and not related to drinking aluminium contaminated water.
If a hospital use water with very high aluminium concentrations for dialysis it can cause "dialysis encephalopathy" which is mentioned in your paper and in patients poisoned with aluminium in this manner some neurological effects similar to Alzheimer's occur.
Thank you dear Henrik Rasmus Anderson. I deeply appreciate your shared information. Please refer to the following link: -

Scientific dissemination of the properties of the natural coagulant will be an ideal setup for propagating these green alternatives in water treatment initiatives. Although the usage of these materials is documented from early days, the scientific elucidation of their
properties or the mechanism is forbidden. But due to recent interest in green chemistry and sustainable management endeavors, these materials are gaining importance in research arena and such works are being initiated in a steady phase. The surge of Moringa oleifera in the water treatment research had thrown light on many such species. Though they are traditionally utilized, detailed investigation on their properties in water treatment are still to be explored.
