Reverse Osmosis is one of the best methods for purifying water. RO Plants are placed in almost every household, businesses, and industrial facilities. Despite possible differences in size, they are all designed to clean and purify water in order to prevent toxins from entering our bodies, when we consume them.
An innovative procedure is used in RO water purification plants to filter out dissolved oxygen, inorganic and organic matter, and other contaminants from water. Now, let’s understand the treatment of wastewater produced from industrial RO Plants before its disposal.
Wastewater/reject water produced from industrial RO Plants
Although, RO is a useful technique for dealing with wastewater, it might be problematic what to do with concentrate or reject water, which typically accounts for 20–50% of the volume of RO feed water.
Particularly, Industrial RO reject / RO concentrate's high salinity can make it impractical, to send to a local sewage plant. The cost of transporting the effluent to a treatment plant may also be prohibitive.
How much-rejected water is produced from industrial RO Plants?
In an industrial RO plant, there is a specific ratio of reject water. By this, we imply that only 25% of the water is purified throughout the filtration process, whereas 75% of the water is referred to as rejected water and is typically not used by people.
The rejected water cannot be utilized for drinking since it has significant impurity, and dissolved solid concentrations.
Which technique is used to treat industrial RO reject water?
An evaporator and a filter press can be used to achieve Zero Liquid Discharge (ZLD). Before being processed, RO Reject/RO Concentrate is kept in a holding tank. The water will be evaporated by the evaporator after being pumped into a heated tank system.
It will thicken and concentrate the wastewater. Pumping the thickened slurry into a filter press will extract the solids. The filter press will also maintain cleanliness in the heated tank and guarantee smooth functioning. The heated tank receives the filtered water from the filter press, and adds it there for evaporation.
Use of an Evaporator
Water evaporation and wastewater reduction can both be accomplished, with an atmospheric evaporative tank. It can truly help you save money and is free of sophisticated machinery and chemistry.
An evaporator is the best option for those searching for the highest evaporation rates, at a particular temperature due to its high efficiency.
Conclusion
RO (Reverse Osmosis) is a process that produces extremely pure water, but it also produces large amounts of wastewater, called as RO Reject or RO Brine Concentrate. The municipal sewer may not be able to handle the disposal of this salinity, and transporting the effluent to a treatment center is expensive.
One of the most cost effective and environmentally friendly methods, of getting rid of brackish or salty water is using ZLD Plants. The entire water purification system will save you money in the long run, because it lacks expensive gear and chemicals.
For your particular wastewater application, Netsol Water Solutions can create RO Reject water treatment system. It is possible to have a closed-loop water treatment system and achieve Zero Liquid Discharge (ZLD).
