Pl. educate, and correct me, pl.: A.Comparison between laterite based technology and Nanotechnology: 1. No toxic chemical leaching from the media 2. Absolutely natural from laterite soil and hence less costly 3. Media can correct pH as it is a natural soil 4. Can remove heavy metals also 5. The media has strong antibacterial property 6. Arsenic removal media does not require regeneration during its lifetime 7. Disposal of media is not an issue as it satisfies TCLP protocol (bound arsenic does not leach out even is left in open) B. Nanotechnology for arsenic removal from groundwater- Nanoparticle based technology: 1. Leaching of toxic nano-particles from the media causing further damage to the health 2. Synthetically prepared Media is expensive 3. Cannot correct pH Along with arsenic, 4. Can remove arsenic only 5. Media does not have antibacterial property . 6. Arsenic removal media requires regeneration by chemicals. 7. Safe disposal is questionable. 8. Possibility that the treated Water contains nano particles, and that these nano particles find access to blood cells in our body is high

Please let me explain. We are referring here to nanotechnology since our (polymer) nanofiltration membranes do contain "nano pores". That is why we consider our production technology as nanotechnology. Our nanofiltration membranes are used for making drinking water, and are approved by NSF, KIWA, etc. That means no toxic chemicals, no nano particles, ect. Our nanofiltration membranes remove low molecular weight organic materials, as residual medicine, pesticides, hardness, color, etc. During operation we do need hardly chemicals for cleaning, while our energy consumption is very low ( <0,3 kWh/m3).
