NSF Certified Food Grade RO Antiscalant [ 5 Kg] Good Chemistry – Scalechecck

Scaling is caused in membranes because the level of hardness salts in the water becomes highly concentrated as it passes through the RO unit. In smaller units scale formation can be prevented by base exchange softening the make-up water but for larger systems that is very expensive. We have developed a range of easy to handle, cost effective RO Antiscalant which increase the solubility of the hardness salts so they remain in solution rather than forming scale on the membrane. Our cost effective RO antiscalants will inhibit a wide range of foulants including: calcium carbonate, calcium sulphate, barium sulphate, strontium sulphate, calcium fluoride, silica and iron.

Scalecheck RO Antiscalant by Good Chemistry is a NSF Certified Product.

Specifications:

RO systems create salt concentrated water streams that could produce scale or fouling. ALTRET Membrane Antiscalants and Cleaners are formulated to be compatible with all brands and types of RO, NF, UF membranes. It provides anti-scaling, antifouling capabilities and keeps fouling material in suspension. ALTRET Cleaners and Support Chemicals are the ideal choice for extending the life of membranes and obtaining a higher level of performance from the elements within the membrane system.

It is proposed to dose Special Food Grade Antiscalants in the feed prior to the cartridge filter for RO system to prevent saturation of various organic salts especially Silica on RO membrane surface on concentration.

AQUASTAT -101 is an aqueous polyelectrolyte based Antiscalant manufactured by Ion Exchange. It has been specially designed to be used in reverse osmosis application.
Reverse Osmosis (RO) is the procedure where deionization of water takes place as it is being passed through under pressure through a semi-permeable reverse osmosis membrane. Using of the reverse osmosis membrane for filtration of heavily soiled water is generally accompanied by some serious threats that may lower down the productivity of the membrane. Generally the three major issues or concern are Degradation, Fouling of RO membranes and Scaling.
Deposition of particles on a membrane that leads to the plugging of the membrane is referred to as scaling. Reverse osmosis (RO) membranes along with the flow passages within the membrane elements tend to scale due to the formation of precipitation of sparingly soluble salts, such as calcium carbonate, barium sulfate, calcium sulfate and strontium sulfate. Most natural waters also comprises of relatively higher concentrations of sulfate, calcium and bicarbonate ions. Scaling generally takes place on RO membranes when the concentration of the scale-forming substances surpasses saturation limit thereby producing added solids within the RO feed water. These substances get hard to be removed from RO membranes due to their low soluble nature. Scaling dwindle the efficiency of the membranes in minimizing the concentration of solids and leads to more frequent cleanings.
RO antiscalant, sometimes mentioned as scale inhibitors, manifests as specialized chemical formulations helps in increasing the solubility of sparingly soluble salts such as CaSO4, CaCO3, BaSO4, SrSO4, and CaF which are the most common scales of concern when added to the membrane system. These antiscalants are to be used as an important component in the operation of the system in order to run the reverse osmosis systems efficiently and in a well organized manner.

AQUASTAT -101- an effective antiscalant exhibits to be a white to amber coloured formulation having a slightly acidic odour. It manifests a pH of 3.5 and is of specific gravity about 1.2. AQUASTAT -101 inhibits the formation and growth of alkaline earth carbonate and sulfate scales. It also helps in dispersing suspended solids and colloids. It acts as an excellent crystal distorter and is efficient at low dosage. AQUASTAT -101 performs as an excellent threshold inhibitor of alkaline earth scales and displays excellent dispersion of suspended solids and colloids.
