Seeking advise for water filter solution

Published on by in Technology

Hello, we are trying to find an effective filtering system for tap water in Brazil.  The 3 main problems are:

  1. high level of LEAD (Due to outdated plumbing system)
  2. ALUMINIUM (Which is used in high quantities as water treatment) and  
  3. PESTICIDE INFILTRATION. (Unfortunately Brazilian authorities do not monitor a lot of pesticides used in agriculture, and therefore we are trying to prevent the  water contamination).

We are looking for an expert to help us choose solutions from existing systems or develop a new solution for us. Thanks a lot!

GianCarlo.

  3. Sorry, there are NO filters that take out emerging contaminants. Filters must be changed but when? A NON- FILTER solution is magnesium oxide beads that place a positive charge in the water that shatters the magnetic bond that holds all Totally Dissolved Solids and simply gasses them out. The beads Never wear out, Never dissolve and Never need to be replaced. This process only costs $40 one time. No filters, No equipment, No electricity.

  4. Bioremediation as an Option

    hello Giancarlo,

    I am reading all kinds of suggestions by various people but I have a natural way to cure.Absolutely no technology needed.Easy to carry anywhere and also implement it at any place.Just leave my bacteria in water for 24hrs and it takes up all the salts from within in 24 hrs.Later you can use the metals to something more useful.

    Another question I have is which pesticide in particular.Just being inquisitive..can send you pictures as well.

    Regards

  6. Hi Giancarlo, Sorry i am late... all the shared the particulars like, lead, aluminum, pesticide can be filtered via AHD Nadi filter water unit. you can install and remove all said these material from drinking water. for more please feel free to visit safe drinking water page at www.ahdpak.org website we at AHD working in Sindh Pakistan and successfully removed all along with biological contamination or drop me email for more information at ahdpak@gmail.com

  7. Dear Geancarlo, how you're doing? I am chemist and biologist and I Work as a environmental consultant here in Brazil. I may help you to understand the current technologias used here and/or present you to some fiter supplyers here that can help you. Please, fell free to contact me leonardo.zanata@hlrservicos.com.

  9. Water filter with KDF backfilling

    Water filter with KDF backfilling

    Flowing water filter with KDF have been proven to be one of the best means to improve the quality of drinking water and tap water according to independent laboratory tests. Municipal water treatment plants, hospitals, beverage manufacturers, restaurants and consumers rely on vodochistiteli with KDF. Traditional KDF components manufactured in two basic embodiments: KDF KDF 55 and 85. KDF is a fine granular filling which consists of a chemically pure zinc and alloys of copper. They eliminate the contaminants from the water by using the principle of the electrochemical redox reactions, known as the redox potential. This is a result of these reactions, many pollutants are converted into harmless substances. Chlorine is converted into harmless chloride salt. Heavy metals such as copper, lead and mercury binds to the KDF alloy and thereby removed from the water. They effectively remove more than 98% of chlorine and up to 98% of water-soluble heavy metals such as copper, chromium, lead, mercury, chlorinated hydrocarbons, hydrogen sulfide, iron metal, lead, arsenic, aluminum, cadmium and mercury. Due to its efficiency KDF capable of removing even the hot water, the speed of water purification is the highest than all of the above filters. KDF is also very effective as compared to reverse osmosis systems. It also removes chlorine and working in a vast range of temperatures and water pressures. Ultraviolet water purifiers are not as effective as cleaners with KDF, because they are working in muddy water and remove inorganic contaminants. At the same time they are very economical, because KDF does not require the use of electricity or light bulbs. Efficiency can be improved KDF in combination with other filter materials. KDF increases the efficiency and life of water filters and controls the multiplication of bacteria, fungi, algae and mildew. Lifetime filters with KDF much longer than other systems listed above.

    KDF-85 ™ is a product of the most modern technology in the field of water filtration. Loading appeared on the basis of copper and zinc in the form of a sponge. These two chemical bonds combined with an opposite-based electromagnetic pol at the molecular level. KDF ™ removes up to 99% chlorine bonds, and, depending on the conditions Vladan - a considerable amount of iron oxides, hydrogen sulfide, lead, while having bakterioubivayuschie and bacteriostatic action. Loading with their exceptional properties otfiltrovyvaniya Chlorine is the ideal product used in public and private-vodoprodno kanalizatsiynyh systems. Depending on your needs and use KDF ™ is available as an additional, remember granulate KDF-55 and KDF-75 fiber. Loading is used among other things as part of the filter module in our, new product - bathing Bowl FHSB.

  10. Lead, Aluminium and Pesticide Removal

    Hi Giancarlo,

    Firstly, the heavy metal contaminants are likely to be soluble therefore will not filter out with the exception of RO use.

    Test the water quality for corrosion/leaching of heavy metals using the Langelier Index calculation (use search engine) may required re-mineralisation with lime/CO2 if corrosive/aggressive water quality based on Langelier calculation..

    Reduce the Alum use by dose optimisation using Jar Testing

    Use activated carbon filtration to adsorb organics (pesticides/herbicides) checking filter inlet and outlet regularly for spent carbon/filter breakthrough.

    Good luck with the project and please contact me privately if further information is required.

  12. www.wateringpipe.co.uk This container allows sedimentation of liquids hence allowing the heavy particles to be flushed away. It could be used on mains connection if the input rate was very low(2L/day) and could be suitable for your problem.

  14. Hey Giancarlo, There are different types of water filtration systems, ones that can be installed at home or at the source. Here are various links that address both: http://www.filterswater.com/water-purification/industrial-water-purification-systems.html http://water-filter-systems-review.toptenreviews.com/ https://www.youtube.com/watch?v=XwCvH7TilsM http://www.tekleen.com/industrial-irrigation-filter-applications/

    First, you just missed to state about your current treatment system for my evaluation ..will be glad if you can share to me,

    1. High level of lead due to outdated piping...  pvc pipes will do

    2. High in aluminum .... you might have used high level of alum containing coagulants. you can replaced it with flocculants- just determine if your waste is cationic or anionic for a specific flocculant to be used

    3. Pesticide infiltration....a more serious issue, there are hundreds of pesticide chemical and some are of smaller molecules where it becomes difficult to filter. I suggest to escalate this with the brazilian authorites to at least minimize the release of pesticide wastes.For now, I suggest that you should go back to item#2. It should coagulate is some degrees of ionic flocculants

    feel free to contact me. Thank you

     

  19. The most simple and inexpensive method is to flush your plumbing system by running the water for one to two minutes before drinking it. Flushing is only necessary if the water has been in contact with the plumbing for at least one hour. Flushing your plumbing system is recommended only if the lead concentration in your running water sample was less than 15 µg/L. It may not be effective in apartment buildings with complex plumbing systems or in homes on public water sources where lead service lines are the source of the lead. In these cases, tap water concentrations of lead may exceed 15 µg/L even after several minutes of running the water. If flushing proves effective, you can conserve water by flushing the plumbing system in the morning and storing water in bottles for use during the rest of the day. Only flushed water from the cold water tap should be used for drinking and cooking, since hot water can dissolve lead more quickly than cold. If excessive lead concentrations persist after flushing, or if flushing is an undesirable method, there are numerous alternatives for reducing lead exposure. Homeowners who have a groundwater well with a submersible pump may want to have the pump checked. If some of the pump’s metal parts are corroding, they could be contaminating the groundwater with lead. Acid-neutralizing filters can be installed to reduce water corrosivity by adding calcium and by increasing the pH of the water. Unlike other treatment options, these filters act to prevent lead from entering the water rather than removing it at the tap. They do this by producing a thin scale that prevents the lead from being dissolved from the pipes and solder inside the plumbing system. Reverse osmosis units (can remove lead and aluminum)and activated alumina filters are very effective in removing lead once it is in the water. These units typically are attached to the kitchen tap and treat only the water from that tap. Pesticides can be found at microgram levels in ground water or surface water. They usually come from intensive agricultural activities. The most common pesticides found in water are Atrazine, DDT, lindane, Carbofuran, etc... In natural waters, pesticides are present at ppb (microgram/L) level. Most of them are hydrophobic and easily removed by adsorption on activated carbon filters. In case of large amounts or large plant capacities, nanofiltration can be a better adapted technology, avoiding hassle of media replacement.

  20. I have a method to do this safely, you can put drinking water in a small container which is made from mud (Egyptian mud) especially for this purpose, and this very cheep method to do this, and we use it in Egypt.

  21. Lead, Aluminum and other contamination removal

    Giancarlo,

    Main question is - are you looking for a domestic (sold to individual house/apartment or to a multi-apartment building) or pre treatment for wells or municipal supply network?
    Also, then we need to look at water analysis (determine levels of lead and aluminum, or other contaminants as well, as perchlorate might be in the water) and expected results.

    we do have a local Brazilian partner, in case you need a local partner. jgur@newterra.com

  24. Treatment Options

    Gianarlo, is this treatment for a single family dwelling (home or apartment) or is this for municipal treatment for a community? The treatment strategies for lead and aluminum are different depending on the application.
