- EC Principles
Water Vision’s innovative and effective Thincell® electrochemical technology can be a critical component of your process and waste water treatment system. Thincell® has proven itself to be a one treatment option for a broad range of pH, contaminants and applications. Thincell can integrate into your existing or planned wastewater treatment system, be installed to target specific hard to remove contaminants, improve operational efficiencies, or it can act as essential protection for sensitive Reverse Osmosis (RO) and Nano-Filtration (NF) membrane technologies.
Reverse Osmosis and Nano-Filtration treatments are used for water purification. After the hard work of ridding water of impurities with Thincell, completely potable water with final removal of salts can be achieved with these processes. Without pre-treatment to remove flocculants, heavy metals and bacteria, spiral wound filters can plug easily and lead to premature shutdowns or costly filter and pump replacements.
In order for NF, RO or similar final processes to be effective, there needs to be a robust intermediate process for removing sub-micron particles. Thincell eliminates these minute particles that other filtering technologies can not. And, since the membrane filters are usually large, the compact, modular Thincell system reduces operating footprint, often critical when used on offshore facilities or space restricted environments. Thincell is the perfect filtration partner for working with these micro clean water technologies.
The expansive Thincell product line from Water Vision allows a broad range of sizes for any flow rate. The Thincell product offering can be modularized, mobile, trailer-mounted, scalable and customizable to fit virtually any requirement.
|Feed Sample||Treated Water PW4||Removal Efficiency|
|Sodium – mg/l||6800||6700|
|Turbidity – NTU||34||5||85.3%|
|Total Suspended Solids (TSS) – mg/l||180||15||91.7%|
|Silica – (mg/l)||24||3||87.5%|
Silica was successfully removed from the following process and waste streams in a Big Spring Refinery:
|Silica Source||Feed Sample||Treated Water||Removal Efficiency|
|E. Bound. Rec. Well||69.3||7.8||88.74%|
Silica reduction in process water minimizes premature scale buildup and reduces maintenance and restoration costs of heat treatment and cooling tower equipment.
Silica Removal to Prevent Scale Buildup
Thincell’s unique electrochemical processes are extremely effective disinfectants. More importantly, the Thincell system disinfectants in one step where Traditional EC requires a second technology (electro-oxidation) to complete the disinfectant process.
Thincell electrochemistry produces an in-situ disinfectant that:
|Feed Sample||Treated Water||Removal Efficiency|
|E Coil Bacteria (mpn)||2,419||0||100.00%|
|Enterococcus Bacteria (mpn)||83||10||87.95%|
It is not well understood why EC reduces hardness concentrations from waters. Public domain information contains considerable data to support EC hardness reduction. The same amount of data exists to refute the claim.
Thincell has reduced hardness concentrations in several applications; however, hardness reduction is very water specific. Removing hardness from waters reduces premature scale buildup.
EC feasibility testing for hardness reduction should be completed prior to selecting EC as a treatment option.
