RO Antiscalant

Reverse Osmosis serves as one of the most critical processes that are involved in the process water treatment to clean water, utilized in various industrial process applications. Reverse Osmosis can be regarded as the process wherein semi-permeable membranes help in separating purified water from contaminated water. It occurs when a pressure is applied to the concentrated side of the membrane resulting in forcing purified water to the dilute side.
Reverse Osmosis is very efficient for the treatment of brackish, surface and ground water for both large and small flow applications. Some examples of industries that use RO water include boiler feed water, food and beverage, pharmaceutical, metal finishing and semiconductor manufacturing to mention a few.
The overall performance of a reverse osmosis system relies on various factors like feed water quality, membrane type, flow control, temperature and pressure. Systems must be well maintained for ensuring effective performance with any fouling requiring cleaning that will maximize the output of the water.
Now, scaling of RO Membranes is one of the critical determining factors of the rate of process water treatment by reverse osmosis system. More the scaling, reduced is the productivity of the system. To effectively control the scaling and to improve the productivity of the system, RO Antiscalant is the best solution one can opt for.
Scalant
What is Scaling?
Scaling can occur when certain dissolved (inorganic) compounds become more concentrated and exceed their solubility limits and precipitate on the membrane surface as scale. The most common scale that develops on RO membrane is that of Calcium Carbonate.

How scaling can be controlled?
The scaling can be controlled in two ways – either by removing scaling after it has formed or simply by protecting or preventing the formation of scaling. This prevention can be done by employing RO Antiscalant chemicals.


RO Antiscalants efficiently controls Iron fouling by sequestration thereby reducing the frequency of membrane cleaning. It helps to check the capacity of RO close to design, and assists in minimizing membrane cleaning cost and shutdowns. It accounts for effective scale inhibition with high recovery rate. It is effective at low chemical dosage thus appears to be economical.

Acid Coil Cleaner leaves the aluminum surface clean and shining bright

Improper refrigerant levels, dirty coils, and worn out compressors or condensers can result in inefficient performance of air conditioning system. An inefficient system tends to force the compressor to work harder than is required decreasing its life span and thereby leading to higher energy bills. The primary energy required in operating an air conditioning system comes from the compression of refrigerant. The hotter the compressor receives the processed refrigerant, the more energy is necessary to force it through the condenser. The refrigerant needs to become cold enough to absorb more heat from the process, therefore an external chiller such as an open evaporative condenser or air blast unit is required. It is crucial for effective air-conditioning operation that the condenser is able to easily reject heat through the cooling airflow and the heat exchanger coils. Energy consumption builds up as the refrigerant vapor pressure increases, where the refrigerant is not sufficien...

Excellent Efficiency Flocculation with Polyelectrolyte

Polyelectrolytes are regarded as polymer chains with an electrolyte group on every repeat unit. When dissolved in a polar solvent, these polymers are charged due to dissociation of small counter ions that leave behind a charged macro ion. Polyelectrolytes include biologically important molecules such as polypeptides and DNA. These are referred to as polymers that are generally used for water purification. These are highly noted for their beneficiary nature of handling problems of slow settling of flocs in water at low temperature, treating soft colored water where they increase toughness of the flocs and enhance its settlement ability. Polyelectrolytes are formulated in a way so as to be used as coagulants and flocculants as well as a sludge dewatering agent in the waste water treatment plants. P olyelectrolyte , thereby, plays an indispensable part in the sludge conditioner formulation. Generally flocculation occurs owing to charges present on the particles. Generally, Pol...
