Hi everyone,
What is a guaranteed process to reduce hardness of wastewater from 5000 and 2000 level to less than 1000 ?
Which is a guaranteed process to reduce silica of 400 to as minimum as possible (circa 50) from waste water ?
Your feedback much appreciated.
Lotic uses it's patented EC-AOP sytem to remove silca 100% and reduce hardness to 15 or less. We have a facility used in Thermal SAGD operations for Exxon. Low operating and consumable cost. This system replace HLS units.
please contact Lotic for more information on how our Patented system works with out chemicals.

Hi Sandeep, chemical softening calculations (using lime or sodium carbonate) have been put into a useful tool - a product of the South African Water Research Commission - called STASOFT version V. This allows you to enter your water chemistry and select a final hardness level. It will then calculate the chemical addition required depending on the chosen softening chemical. The programme also allows you to ensure the water is stable after treatment (Langelier Saturation Index). Other practiced methods of softening are ion-exchange and membrane processes (nano-filtration).
Silica reduction in wastewater will also be achieved by addition of lime (and hence the water softened at the same time). Alternatively membrane processes may be considered (microfiltration). However it depends on what the treated water will be used for as this may be costly.

To Arturo Constante, The AOP will not working as there are inorganic chemistry and in max. oxidation level.

Hot Lime softening with Dolomite is likely to help

If you want to be safe, lime + sodium carbonate softening
in order to obtain high silica removal efficiency a dosage of Mg salt (MgOH or MgCl2) is often requested, according to ratio Mg/silica on your raw water

Advance Oxidation Process
Actually I offer my technology to purify any kind and flow of waste or salty water into potable with zero emission at low operating costs if you or your client were interested.

with AOP only organic matter decreased not inorganic matter.

What are you going to oxidize with calcium and magnesium hardness and silica being the concerns?

lime softening will help you, but needs more specific analyses of the waste water
