Making RO Antiscalant Chemical - Acuro Organics Limited

What Is RO Antiscalant Chemical? RO, or reverse osmosis, an antiscalant chemical is made in the process of purifying water by using RO, which can remove up to 99% of the dissolved salts and chemicals from water. This purified water is generally used for industrial purposes, or to provide an alternative source of drinking water to areas where it may be unavailable or undrinkable. RO antiscalant chemical also helps reduce problems such as scale buildup within the system that could lead to more serious issues down the road, like clogged filters and other malfunctions in the system itself. 

Process of making RO water 
The reverse osmosis water purification process involves six basic steps:
1. Pretreatment,
2. Feed preparation,
3. Pre-filtration,
4. RO permeate generation and recirculation,
5. Post-filtration,
6. Product water storage, 

The RO process begins with the pretreatment of incoming raw water to remove unwanted particulates. Pretreatment systems include magnetic filters, screens, and belt filters to remove solids that could potentially plug membrane pores. Membrane manufacturers offer surface modifications that improve fouling resistance as well as simplify cleaning procedures. After pretreatment, incoming water is divided into two streams. A portion flows through a feed tank where it is mixed with concentrated sodium chloride solution or caustic soda (NaOH) to prevent scaling during later stages. To allow for effective mixing, tank diameters should be at least three times greater than RO component pipe diameter so that liquid velocities do not exceed a maximum of 1 ft/s (0.3 m/s). Stable solutions can be achieved by introducing feed gradually through an educator or by manual means such as submerging a clean pump impeller in caustic solution while mixing vigorously by hand. Concentrated salt solutions are corrosive so contact between them and RO components must be avoided as they can cause significant damage. For example, concentrations as low as 5% NaCl will attack stainless steel piping; 3% NaCl will eat away at silicone rubber and Viton seals, rubber tubing swell up and eventually burst; 0.5% NaCl may delaminate Teflon coating material from RO membranes; etc. Traditionally solvent-based alkylphenol ethoxylate detergents have been used to reduce membrane surface tension and thus minimize foaming which causes back-pressure on upstream pumps however more recent investigations indicate that the use of non-corrosive food grade phosphates produces equally effective results.

What you need..? 
Caustic Soda, Nitric Acid, and Water. You need to determine the concentration of caustic soda in the solution. Then calculate what percentage of caustic soda is Nitric acid. Take the desired amount of RO antiscalant chemical in your container add some amount of Nitric acid and mix it thoroughly. Then slowly add water and mix it gently. Add more water if necessary to make a thick paste-like consistency with little froth on top. Allow the mixture to stand overnight and stir it again before using it. The resulting RO antiscalant chemical works best after 24 hours of curing time.

How to do it..?
Manufacturing RO antiscalant chemical is a process that starts with a different chemical in its raw form, ammonia. The process of making an RO antiscalant begins when ammonia and water are mixed together to create liquid concentrated fertilizer (LFC). From there, LFC undergoes several modifications (including cooling, filtration, and evaporation) to end up as a powdery ammonium nitrate product.

5 Uses of Antiscalants in an RO Plant - Acuro Organics Limited

Many homeowners and businesses use RO systems to purify their water, removing harmful minerals and chemicals from their tap water. But what does antiscalant mean? And why are antiscalants used in RO plants? Here’s an overview of the uses of antiscalants in RO plants, plus a few ways they can be harmful to your system if not used correctly. In addition, you can find out how to get the best RO water filters at the best prices with our review of the top five brands on the market today!  1) Prevent Scale Buildup Scale is typically caused by mineral deposits. The key thing to know about scale is that it’s mostly comprised of calcium and magnesium, so an antiscalant prevents these minerals from sticking together. When calcium and magnesium are separated they can be flushed out without causing any problems with your system. Since scale buildup is one of the RO plant's biggest issues, employing a chemical antiscalant is crucial for preventing and removing scales from your system. However,...

What are the Benefits of Antiscalant?

Adding antiscalant to your water system has long been known to reduce scaling on internal surfaces and equipment and can prevent problems such as poor flow, bad taste and odor, pressure fluctuations, and equipment breakdowns. However, most water professionals aren’t fully aware of the full benefits that can be gained from using antiscalants ( water treatment chemicals ) as part of their routine maintenance program. Here are four benefits of antiscalant that you may not have been aware of before now.  Why Should I Care About Discharge/Antiscalant:-   Discharge is a corrosion inhibitor that lowers your cooling tower’s water pH from 6.5 to approximately 7.2 (the recommended range is 7.0–7.6). A discharge/antiscalant helps prevent limestone formation inside your cooling tower, and it also increases efficiency by preventing scale buildup on your equipment and pipes. Discharge Rate & The Occurrence Of White Sludge:-   In the alkaline process, high calcium sulfate is produc...
