Reverse osmosis (RO) uses crossflow membrane filtration and thus, antiscalants are used so that the contaminated or the reject water, leaves the system as a concentrated brine. The unpurified portion of the water is left with all the salts, organics, and colloidal particles that the membrane rejects as it flows to the permeate side.
The operating recovery will increase along with the brine's concentration. Scales start to form in the brine when the concentration of dissolved salts is above saturation. The same is true for organic and colloidal particles, which grow more fouling-prone as they concentrate along the membrane system's length.
Let’s have a look at these reverse osmosis antiscalants.
In reverse osmosis (RO) membrane systems, Netsol Water has developed very efficient inhibitors, which remove the most difficult scales and dramatically reduce colloidal and organic fouling. All feedwater sources including groundwater, wastewater, fresh surface water, ocean, and municipal water, respond favourably to these antiscalants.
Our highly effective reverse osmosis (RO) antiscalants work at surprisingly low dosages, and can prevent scales even at very high saturations. These antiscalants can minimise cleaning frequency, eliminate the requirement for acid dosing, and let facilities to run at greater recoveries.
Various types of scales
Calcium carbonate, calcium phosphate, calcium sulphate, barium sulphate, strontium sulphate, calcium fluoride, iron hydroxide, iron phosphate, silica, and colloidal foulants are among the scales, which are controlled by RO antiscalants. Our RO anti-foulants spread colloidal silica and organic materials in the natural environment.
How do Reverse Osmosis (RO) Antiscalants work?
Specialty chemicals called RO antiscalants are applied before a reverse osmosis membrane system. These compounds, known as scale inhibitors, are made to stop or reduce the growth of mineral scale on membrane surfaces. For a reverse osmosis system to consistently operate, the proper antiscalant is essential.
1: Now, when dissolved minerals in water are allowed to concentrate past their saturation point, when they will begin to emerge from solution, mineral scale is created.
2: The water poured on the window appears clear, but each drop contains dissolved minerals, similar to water spots on a window.
3: The dissolved minerals in that water remain behind as it evaporates and manifest as hard water.
4: Water is driven through a reverse osmosis membrane system, but the dissolved minerals cannot move through and are left behind.
5: For RO systems to run continuously, it is crucial to prevent scale from building up on the membrane surface. This would prohibit water from passing through.
The improper antiscalant chemical can fast promote scaling and the ensuing performance loss. However, scaling issues can be totally removed by administering the right RO antiscalant at the right dose rate.
The dosage rates for RO antiscalants are normally quite low, and they can be used in conjunction with other chemicals given upstream. Additionally, RO Antiscalants generally meet all environmental standards for chemicals, fed to reverse osmosis water treatment facilities and are safe to handle.
