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
