Reverse osmosis system Expoter in Africa

Reverse osmosis occurs when the water is moved across the membrane against the concentration gradient, from lower concentration to higher concentration. To illustrate, imagine a semipermeable membrane with fresh water on one side and a concentrated aqueous solution on the other side. If normal osmosis takes place, the fresh water will cross the membrane to dilute the concentrated solution. In reverse osmosis, pressure is exerted on the side with the concentrated solution to force the water molecules across the membrane to the fresh water side.

Reverse osmosis is often used in commercial and residential water filtration. It is also one of the methods used to desalinate seawater. Sometimes reverse osmosis is used to purify liquids in which water is an undesirable impurity (e.g., ethanol).

The process of removing divalent cat ions, usually calcium or magnesium, from water. When a sample of water contains more than 120 mg of these ions per liter, expressed in terms of calcium carbonate (CaCO3),  it is generally classified as a hard water. Hard waters are frequently unsuitable for many industrial and domestic purposes because of their soap-destroying power and tendency to form scale in equipment such as boilers, pipelines, and engine jackets. Therefore it is necessary to treat the water either to remove or to alter the constituents for it to be fit for the proposed use.

Water described as "hard" is high in dissolved minerals, specifically calcium and magnesium. Hard water is not a health risk, but a nuisance because of mineral buildup on fixtures and poor soap and/or detergent performance. Hard water is

Diffusion is the movement of molecules from a region of higher concentration to a region of lower concentration. Osmosis is a special case of diffusion in which the molecules are water and the concentration gradient occurs across a semipermeable membrane. The semipermeable membrane allows the passage of water, but not ions (e.g., Na⁺, Ca²⁺, Cl^-) or larger molecules (e.g., glucose, urea, bacteria). Diffusion and osmosis are thermodynamically favorable and will continue until equilibrium is reached. Osmosis can be slowed, stopped, or even reversed if sufficient pressure is applied to the membrane from the 'concentrated' side of the membrane.

Home water softener manufacture in Noida, NCR

The standard whole-house softener works on the principle of ion exchange, termed "cation exchange." It conditions hard water by substituting sodium chloride (salt) or Potassium chloride for the hardness minerals such as calcium, magnesium, and iron.

Inside a cation-exchange softener, the house water supply flows through plastic-like beads called "resin," arranged in columns called "resin beds" that reside in the "resin tank." These beads attract the mineral ions of hard water while giving off sodium ions. To periodically recharge the beads with sodium ions, they're flushed with salt water (brine), a process that removes the hard mineral ions from the resin and discharges them as waste. Once excess sodium is rinsed away, the cycle begins again.

.Reverse Osmosis is a process where water is demineralized using a semipermeable membrane at high pressure. Reverse osmosis is osmosis in reverse. So, what is osmosis? Osmosis is most commonly observed in plants. If you don't water your plants they wilt. A plant cell is a semipermeable (water flows through the membrane but salts don't) membrane with the living stuff on the inside in a salt solution. Water is drawn into the cell from the outside because pure water will move across a semipermeable membrane to dilute the higher concentration of salt on the inside. This is how water is drawn in from the ground when you water your plants. If you salt your plants (over fertilize or spill some salt on the grass), the plant will wilt because the salt concentration on the outside of the cell is higher than the inside and water then moves across the membrane from the inside to the outside.
To reverse this process, you must overcome the osmotic pressure equilibrium across the membrane because the flow is naturally from dilute to concentrate. We want more pure water so we must increase the salt content in the cell (concentrate side of the membrane). To do this we increase the pressure on the salty side of the membrane and force the water across. The amount of pressure is determined by the salt concentration. As we force water out, the salt concentration increases requiring even greater pressure to get more pure water
