Product Details:

Reverse osmosis (RO) is a water purification technology that uses a semi permeable membrane to remove ions, molecules, and larger particles from drinking water. Reverse osmosis can remove many types of dissolved and suspended species from water, including bacteria, and is used in both industrial processes and the production of potable water. 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 solvent molecules) to pass freely. The membranes used for reverse osmosis have a dense layer in the polymer matrix—either the skin of an asymmetric membrane or an interfacial polymerized layer within a thin-film-composite membrane—where the separation occurs. In most cases, the membrane is designed to allow only water to pass through this dense layer, while preventing the passage of solutes (such as salt ions).

An antiscalant is a pretreatment injected into the feed water before the feed water enters the RO membranes. Its presence delays the reaction between calcium magnesium and bicarbonate. This result is scale not forming as the water is being purified by the RO.RO membrane systems that use antiscalant avoid mineral scaling and thus can operate for extended periods of time between membrane cleanings. Also, antiscalants allow RO membrane systems to remove far more pure water from each gallon of feed water than would otherwise be possible. Antiscalant is a pretreatment water additive for reverse osmosis system that is highly effective in preventing the membranes from scaling. Before the feed water enters the reverse osmosis membrane, an antiscalant is injected into the water and sent it through the system.

Ro Antiscalant is a pretreatment water additive for reverse osmosis system that is highly effective in preventing the membranes from scaling. Before the feed water enters the reverse osmosis membrane, an antiscalant is injected into the water and sent through the system. There are a large number of chemical suppliers who supply a variety of proprietary antiscalants and dispersants to improve the operation of ro and nf systems. Antiscalants are a family of chemicals designed to inhibit the formation and precipitation of crystallized mineral salts that form scale. RO antiscalant helps to control inorganic scales of calcium, magnesium, barium, strontium, fluoride, iron and silica. RO antiscalant ensures above 80% reduction in scaling tendencies if used continuously. Antiscalant for Reverse Osmosis is invulnerable in handling and use with a very high recovery rate of membrane.

Using RO antiscalant helps to control inorganic scales of calcium, magnesium, barium, stronium, fluoride, iron and silica. RO antiscalant ensures above 80% reduction in scaling tendencies if used continuously. ... Antiscalant forReverse Osmosis is invulnerable in handing and use with a very high recovery rate of membrane. In membrane desalination operations at high recovery ratios, the solubility limits of gypsum and calcite exceed saturation levels leading to crystallization on membrane surfaces. The surface blockage of the scale results in permeate flux decline, reducing the efficiency of the process and increasing of operation costs. The effects of scale on the permeation rate of RO systems is illustrated in the following figure. Following an induction period, plant flow decrease rapidly.
