Filter Media and Resins Run Down
At J&F we have a wide range of different filter medias & resins available, whether you need it in small or large quantities, we are the people to go to. It can be a bit of daunting going through all the variations on offer. Let’s just get into what we have to offer shall we?
First up we have Birm. This is an efficient and economical media, that can tackle and dissolve any iron and manganese compound in your water. There are a lot of advantages to this media such as long material life with relatively low attrition loss, a wide temperature performance range and extremely high removal efficiency. Birm filter media is easily cleaned by backwashing to remove the precipitant and it’s not consumed in the iron removal operation. Birm offers a tremendous economic advantage over many other iron removal methods. This particular media can be used pretty much anywhere, including a gravity fed or pressurized water treatment system.
CARBON: AQUASORB CS
Next up on our long list of filter medias & resins we have Carbon. Ideally suited for the removal of oxidizing agents such as chlorine and ozone from water. This media is a high activity granular activated carbon, manufactured by steam activation from select coconut shell charcoal. It can be used for the following; reducing chlorine, improving taste, eliminating odours and reducing dissolved organics. It’s a pretty good all-rounder! Another important feature of this material is its superior mechanical hardness and the extensive “dedusting” during its manufacture which ensures an exceptionally clean activated carbon product.
The next media up that is also manufactured by steam activation of select coconut shell charcoal, is AquaSorb® CX-MCA. The catalytic activity of this activated carbon makes it highly effective for the removal of chloramines and hydrogen sulphide from potable water. AquaSorb® CX-MCA can be used for eliminating hydrogen sulphide (rotten egg smell), chlorine reduction, chloramine reduction and removal of dissolved organics.
The first of many resins is next, De-Alk Resin. This resin is a macro-porous weak acid cation exchange resin and is used for dealkalisation and deionization in water. This resin is for simplex and duplex water systems only and used to help with pH correction. Water must be within a pH of 6.8 – 7.2 to be optimal for human consumption. pH levels outside of these levels can also cause corrosion to pipes (often seen as a blue/green stain).
De-Min Resin, or also known as RA370, is a high-capacity mixed bed ion exchange resin, for direct water purification and demineralization. This resin is used for water purification, demineralization (also referred to as deionization), refining water for a range of appliances and offers efficient high silica removal. Demineralization is typically described as the removal of all cations (e.g. calcium, magnesium, sodium, potassium, iron and other heavy metals) and anions (e.g. bicarbonate alkalinity, chloride, sulfate, nitrate, silica and CO2) from a solution in exchange for H+ and OH- ions. This reduces the total dissolved solids in the solution. This is required for many sensitive processes, such as high-pressure boiler operation, food and pharmaceutical application, and electronics production, so this is a pretty important resin and very useful.
Next up is the best of the best, and a known favourite at J&F, the advanced five-stage treatment media for an all-in-one solution, Ecomix.
Ecomix is a unique blend of five different filter medias that provides an all-in-one treatment for the removal of iron, manganese, ammonia, organic matter and water hardness and it’s effective over a wide range of operating conditions. Two of the ingredients, FerroSorb and HumiSorb are unique to Ecomix, providing a highly effective method of treatment for problem water, but it doesn’t just end there. Ecomix has other ingredients including an inert layer for treating oxidised iron, cation exchange resin for softening water, and quartz sand for ensuring uniform flow across the vessel. Lets get into a bit more about these two unique medias shall we?
You can find out more about Ecomix and it’s applications by reading our Ecomix guide that you can find here.
Filter-Ag Plus is great for removing the following from the water; suspended irons, organic matter, silt & dirt. It’s an all-natural, environmentally safe product, that has a surface area one hundred times greater than silica sand, resulting in better filtration. Compared to normal sand filters, filter-Ag Plus’ rough surface and internal porosity allow for much longer and more effective filter runs and a high capacity for sediment loading. This reduces backwash frequency and conserves water.
Next is Juraperle. This filter media is great for treating water with Low pH levels, iron, manganese, and CO2 removal. Juraperle is a sacrificial granular media for correcting the pH level of low pH water. Primarily made up of calcium carbonate, Juraperle dissolves into the water supply, naturally lifting the pH level in the water. Juraperle can also aid in the removal of iron and manganese due to the oxidation process. This iron and manganese needs to be removed from the media, which can be done via a backwash process performed every day. By removing the iron and manganese from the media, Juraperle remains capable of dissolving into the water.
NITRATE REMOVAL RESIN
Did you know that nitrates are one of the most common contaminants in private UK water sources? Unfortunately, nitrates are highly soluble in water and at high enough levels, if not filtered, can cause health problems. Nitrates can also cause “Blue Baby Syndrome,” where oxygen transportation in the bloodstream of babies is hindered. High levels of nitrates in water can also be carcinogenic. Therefore, it is important to control the levels of nitrates to ensure it is safe to drink. So this is where Nitrates Removal Resin comes in handy. They are commonly found in places near farms, golf courses, wastewater disposal sites, landfills, livestock facilities and crop fields. Therefore, it is important to control the levels of nitrates to ensure it is safe to drink.
Pyrolox is a long-standing water filtration media, so long in fact its been around for over 75 years, so it’s doing something right! It is effective at reducing iron, manganese and hydrogen sulphide in problem waters. It eliminates them by a process known as oxidisation. Particulates from the oxidised iron, manganese and hydrogen sulphide become trapped in the media and are then removed from the system during a backwash cycle.
Semidol is a simple media, designed to correct low pH levels in acidic water quickly. It’s particularly effective when used to treat very low pH levels in water.
Seimdol reacts neutrally during the water treatment process, which means it does not interfere with other medias and causes no problems during the switch over process. Semidol is commonly used to treat low pH in water for drinking, swimming pools and industrial processes.
Softener Resin. One of the most common issues with water is water hardness. When you treat hard water it prevents limescale and ensures a longer life from items such as dishwashers, washing machines, showers and boilers. Adding on to the many benefits of softened water, it also helps to reduce heating bills, results in softer laundry and soap that lathers much easier.
Here’s how it works; the resin is made up of tiny beads which are positively charged with sodium ions. The calcium and magnesium ions contained in calcium carbonate and magnesium carbonate are negatively charged. Just like a magnet, the positive resin beads attract the negative calcium and magnesium ions. In return, the sodium ion is deposited to the carbonate, because “opposites attract.” What you are left with is sodium carbonate in the water which does not cause limescale and gives you softer water.
Last but certainly not least is Tannin Resin. This is ideal as a pre-treatment for UV disinfection and removes tannin and colour from water. What we mean by this is water that contains things like plant and animal matter as well as sediment, all of which can cause water to appear “stained” or coloured; typically a brown, green or yellow. Evidently, this can sometimes result in undesirable contaminants present in the water as well as giving it a simply unappealing colour. In almost all instances, you’ll want to treat the tannin to ensure it does not interfere with the final product produced; whether that’s drinking water, food and beverage production or items and products created commercially and industrially.
Coloured water can also be an indicator that other contaminants are present in the water that can be harmful, such as iron, manganese and sediment.
