High TDS (1349 mg/l) - Solution Required for Full House Supply

Hi 

I am looking for a complete solution to supply my home with borehole water and 'get-off the grid'

My water test results:

• PH @ 25°C : 7.3
• EC @ 25°C mS/m : 225
• Na mg/l : 394.6
• K mg/l: 67.0
• Ca mg/l: 81.7
• Mg mg/l: 75.2
• Fe mg/l: 0.3
• Cl mg/l: 321.6
• CO3 2 mg/l: N/A
• HCO3- mg/l: 994.4
• SO4 mg/l: 36
• B mg/l: 2.71
• Mn mg/l:

1. Water is not potable as per BIS 15000 for Drinking Water. You may have to go for Softener to have utility water & advance technology like Reverse osmosis for drinking water

2. No oxidisable matter neither bacterial contamination?

3. Is this chemical analysis typical of groundwater sources in your area? Removing this salinity will be energy-intensive so difficult to reconcile with your off-grid ambition. 

4. It is all about how much energy you are willing to pay for....

   I would suggest water generated from air

   Ro will be environmental hazard

5. Hard water is safe for drinking and does not cause any health issues unless there is a high contamination level of metals like arsenic. The best way is to take the help of a TDS metre. The TDS metre helps you measure the TDS value in your water supply. As an average, a TDS value of more than 200 PPM in water makes it hard water. But it also depends on the other contaminants in your water. 

   1. You could add a whole house sediment filter to your main line into the house. There are a couple different kinds (replaceable paper, cleanable metal screen, and more fancy options).
   2. You could add a reverse osmosis system and significant size storage tank to store enough RO water since the system won't keep up.

   "Water containing TDS concentrations below 1000 mg/litre is usually acceptable to consumers, although acceptability may vary according to circumstances. However, the presence of high levels of TDS in water may be objectionable to consumers owing to the resulting taste and to excessive scaling in water pipes, heaters, boilers, and household appliances Water with extremely low concentrations of TDS may also be unacceptable to consumers because of its flat, insipid taste; it is also often corrosive to water-supply systems "

6. Introduce UF and RO 

    

7. 
   

   You can also use solar energy and EDR or RO to desalinate, however the capital cost would be much higher than to have municipal potable water supply.

8. Why not get off the grid using atmospheric water generators?

9. At such TDS, the cost of system such as media filtration and reverse osmosis will be too high in cost and won't be feasible.Better go for the grid.

10. Good morning, to use your hight TDS borehole water you need a pretreatment (multimedia filter for instance) and a BW-RO. I also strongly advise dosing a little amount of CO2 and seting-up a maërl filter (Calcium bicarbonate). Please note that Boron concentration will probably always exceed OMS limit (you have to run RO simulations to be sure).

    Good luck
