Reverse osmosis
(RO) is a membrane-technology filtration method that removes many types of large molecules and ions from solutions by applying pressure to the solution when it is on one side of a selective membrane. The result is that the solute is retained on the pressurized side of the membrane and the pure solvent is allowed to pass to the other side. To be "selective," this membrane should not allow large molecules or ions through the pores (holes), but should allow smaller components of the solution (such as the solvent) to pass freely.

In the normal osmosis process, the solvent naturally moves from an area of low solute concentration (High Water Potential), through a membrane, to an area of high solute concentration (Low Water Potential). The movement of a pure solvent to equalize solute concentrations on each side of a membrane generates osmotic pressure. Applying an external pressure to reverse the natural flow of pure solvent, thus, is reverse osmosis. The process is similar to other membrane technology applications. However, there are key differences between reverse osmosis and filtration. The predominant removal mechanism in membrane filtration is straining, or size exclusion, so the process can theoretically achieve perfect exclusion of particles regardless of operational parameters such as influent pressure and concentration. Reverse osmosis, however, involves a diffusive mechanism so that separation efficiency is dependent on solute concentration, pressure, and water flux rate. Reverse osmosis is most commonly known for its use in drinking water purification from seawater, removing the salt and other substances from the water molecules.
RO Anti Scalant:
Scale and fouling can be very damaging to your membrane system, costing you a loss in production and money. Thatís why itís important to invest in antiscalant chemicals to clean the system properly.

Scale is a white chalky buildup of calcium minerals that occur as the water precipitates. Some common examples of scale are calcium carbonate (CaCO3), calcium sulfate (CASO4), barium sulfate (BaSO4), and strontium sulfate (SrSO4). Less common but equally problematic are silica (SiO2) and calcium fluoride (CaF) scales. Over time without the proper treatment scale and other contaminants can build up and reduce the production flow of your system. To counteract or prevent this from occurring, RO chemicals such as antiscalants can be used to reduce the amount of contaminants that attach to the membrane surface during production. Antiscalants help to keep membranes from fouling so that water will flow smoothly through. Many antiscalants work to combat scaling and fouling by bonding with whatever contaminants are in the water, preventing it from attaching or sticking to the membrane surface.
Membran Cleaner :
membrane cleaning chemicals provide better cleaning, extend reverse osmosis membrane life and is more cost effective than on-site cleaning. This off-site membrane cleaning process is specifically designed to restore RO membranes to or near the original manufacturer's performance specifications.
Reverse Osmosis Biocides
Non-oxidizing, non-ionic biocides and antifoulants can be used either on line or as part of a cleaning program to control biofouling in reverse osmosis (RO) membranes. When used as an on-line treatment, the biocide should be dosed prior to the RO system to control bio-growth in the membranes.
During normal operation over a period of time, the RO membrane elements are subject to fouling by suspended or sparingly soluble material that may be present in the feedwater. Common examples of such foulants are colloidal deposits, organic and biological deposits, calcium carbonate scale, calcium sulfate scale, and precipitation of silica compounds. Foulants will have an adverse effect on the membrane performance and are generally progressive.Chemical cleaning of the RO membranes is generally performed to remove foulants that have accumulated on the membrane surface or elsewhere within the RO element. Chemical cleanings are designed to remove the foulants by either:
Coagulants & Flocculants...
WST coagulants and flocculants are formulated to assist in the solids/liquid separation of suspended particles in solution. Such particles are characteristically very small and the suspended stability of such particles (colloidal complex) is due to both their small size and to the electrical charge between particles. Conditioning a solution to promote the removal of suspended particles requires chemical coagulation and/or flocculation.

Coagulants neutralize the repulsive electrical charges (typically negative) surrounding particles allowing them to "stick together" creating clumps or flocs. Flocculants facilitate the agglomeration or aggregation of the coagulated particles to form larger floccules and thereby hasten gravitational settling. Some coagulants serve a dual purpose of both coagulation and flocculation in that they create large flocs that readily settle.
