THE FUTURE OF NANOTECHNOLOGY IN WATER DESALINATION

Nano scale science plays an enormously positive role on the everyday life of every one.

The feasibility of nanofilters helps us to develop  ,along –term  &profitable relationship due to the hi-tech & the advantageous of these nanotechnologies which are :-

1-long term use

2-Resuable

3- No power & No pressure

4- Filters media , low cost & reusable

In nanotechnology desalination we replace the RO unit with NF units , the number of nanofilters (NF) & their  capacity will depend on the capacity of the plant .

Nano technology process Merit:-

(1 ) Quality standard:-

Contaminated free water with ng/l ,nanowater with 1000 time mora quality .

(2)  Power operating cost :-

     Cost-effective ,No RO used , it will reduce the cost to 50% of price.

(3) Product water volume:-

Large volume production , 2/3 volume of feed water .

(4) Durability :-

It is reusable for years , durable station .

Visual detection point using nano membrane sensor layers for selective toxins with response time of minutes  .

Note:- the color change means  the membrane should be changed or washed .

 

 Water Desalination plant (nano membrane stages)

The manufacture replaces the RO unit by three membranes

(1) Filter tank  #HOM-V

This filter remove TDS & contains layers containing with active & selective adsorbents for each of the following :-

  • Salts or minerals (Na.Ca &Mg)
  • Toxicants (metals) –Radioactive elements if any
  • Arsenic contaminated water , if any
  • Some chemicals & hazardous

 

Exchange of the filter medium :- filter media has passed the period of use will be replaced, with a new tank  , filter media in the tank is not unplugged .

Tank that contains the older media as it is sent to the manufacture to recycle it .

(2) Filter tank  #HOM-R

The other elements or particles that remained for HOM

TDS control are as follow :-

  • Salts or minerals (Na.Ca &Mg)
  • Sulfur &phosphate
  • Organic species like pesticides ,virus ,bacteria , herbicides , bad taste, odor &cysts.

Exchange of the filter medium :- filter media has passed the period of use will be replaced, with a new tank  , filter media in the tank is not unplugged .

Tank that contains the older media as it is sent to the manufacture to recycle it .

(2) Filter tank  #HOM-CTO

In that stage we use meso carbone filter   to get ride of  all the remaining contaminants

Quality of Nanowater
