When it comes to wastewater treatment there are several options. One of the most common technologies used is Reverse Osmosis. Reverse Osmosis is the process of water being pushed through a membrane in a way that goes against the usual flow of water. Pressure is used to force the wastewater through a semi-permeable membrane which cleans it. The process allows the membrane to grab particulates and pollutants from the water as it is pressed into a lower solute liquid. Lower solute means there is less contained in the water, which is the opposite of how Osmosis works, hence the name.
Reverse Osmosis has many applications and is currently considered one of the better means of treating wastewater. It is popular with desalinization plants as it is able to catch a good deal of salt as the water is moved through. Many power plants use it as a means of recycling wastewater for their cooling towers and boilers. Car washes employ RO, in some cases, as a means of recycling their wastewater for use in the final rinse stage since the resulting water has such a low mineral count. This prevents spotting on cars.
There are several drawbacks to the process, however. First is the membrane itself. Eventually the filter gets clogged and will often need to be replaced. There is also a matter of volume as the membrane is only able to handle so much water through it over the course of a day. Water that comes from the RO process is also highly acidic and can cause corrosion through copper pipes and rusting in steel tanks. In industrial applications it eventually reaches a point of diminishing returns in efficiency as the process is further pushed. RO is very labor intensive and costly.
Electrocoagulation is a technology that is not newer than RO, but its usage has not been as widespread due to inefficiencies in older systems. Those inefficiencies have been worked out and the popularity of electrocoagulation has been growing steadily. EC, as it is also known, is the process of using electricity to alter the chemical properties of contaminants. It breaks down emulsified chemicals such as oil by altering the chemical chain. EC also causes the ions in contaminants to reverse polarity and bind into a different, inert substance which is where coagulation comes in. The result is a sludge that is easily dewatered and separated from the newer, cleaner water.
Where electrocoagulation shines is with pollutants that are not able to be filtered. Emulsified oil, suspended solids, heavy metals, and TPH are all made inert and easily removable from the water. These dangerous substances, that include arsenic and uranium, are rendered harmless as their more damaging properties are removed as they are altered. The applications of electrocoagulation include: industrial water cleaning, onsite wastewater treatment system, and small scale water purification for personal use.
EC is safe to use as it does not use all the harsh chemicals like chemical coagulation, can be virtually odor free as there is no need for retention ponds, and it is a rapid process allowing larger quantities of wastewater to be cleaned in a shorter period of time.
Electrocoagulation does not clean everything. It can only affect contaminants that have conductive properties. As a result it cannot be used as the active desalinization process. Salt does not transfer electricity very well so it is not removable. Larger objects also need to be strained from the wastewater before the EC process is used on it. While inert and safe for dumping, the sludge that results from the process also does need to be disposed of.
So which is the better answer? The tried and true process of Reverse Osmosis? Or the increasingly efficient Electrocoagulation? Leave a comment below to let us know what you think. Regardless of whose opinion is right, Clear Choice Wastewater Treatment, LLC feels we can provide the best option using our Electrocoagulation technology.
With our No Capital Cost onsite wastewater system we can provide state of the art, efficient, effective, and easy to use water cleaning for lots of different types of wastewater. As an onsite wastewater treatment plant our EC technology can handle large amounts of mixed wastewater including: septage, grease traps, portable toilet waste, and oil interceptors. Our system is able to handle any type of oil waste and oil-mixed water better than any other technology out there. The unit also fits in an area that is about a quarter of an acre of land.
