Water Softener - Aqua Conditioner

Aqua Conditioners Technology The Aqua Conditioners technology is unique because it: Prevents scale & also breaks down existing scale – without salts, chemicals or electricity Provides an endless supply of ‘softened’ water without further cost or maintenance What is a Aqua Conditioner system? According to some very narrow definitions, a ‘water-softener’ changes hard water into the soft water only with the removal of calcium from the water with sodium carbonate. This means the Aqua Conditioners unit is not technically a water softener as it does not add chemicals or remove any minerals from the water flow. However, it does turn ‘hard water‘ into ‘soft water’ as characteristics of the calcium molecules changes so that it does not drop out and cling to other surfaces. The Aqua Conditioners device prevents scale from forming by neutralizing the scale producing properties of the minerals in hard water. This means the neutralized mineral particles will flow freely through the system without sticking to the surfaces. What does the Aqua Conditioners technology do? The technology is designed to protect plumbing systems and other surfaces from the negative effects of hard water minerals. The scale and residue that usually sticks to pipes, valves and other surfaces is prevented from forming by changing the hard minerals in the water into inactive microscopic particles. These inactive mineral particles stay suspended in the water (much like minerals are suspended in milk) and flow freely, unable to stick to surfaces. Most importantly, unlike hard water minerals, if the inactive mineral particles occasionally drop out of suspension they can easily be washed or wiped away without the use of caustic chemicals. How does a Aqua Conditioners work? The unit is installed directly on your water line. It has at its core a non-sacrificial, catalytic converter that is non-ferrous, resists rusting and corrosion, and is totally non-toxic and ecologically safe. The unit requires no salt, no resins, no electricity, no magnets, no back washing and no maintenance. Using a unique combination of metals within the alloy core plus the principle of turbulence (the Venturi effect), the water flow is forced through the Aqua Conditioners unit where an electro-chemical catalytic reaction occurs. During this reaction, electrons are transferred between molecules, completing missing electrons and so new mineral compounds are formed. The electro-physical changes in the minerals neutralize their scale producing properties. The result is that previously ‘hard’ minerals are changed from being large molecules into inactive, microscopic mineral particles. The Chemistry Blended in a specialized foundry process, each alloy core is made up of a number of dissimilar metals scientifically selected from the anode and cathode galvanic scale. The alloy is not a sacrificial anode (ie; does not need replacement). On contact with water thousands of intense galvanic electrochemical reactions occur along the length of the alloy core. Minerals are attracted to these galvanic sites as they flow through the system. The electrical charge or zeta potential of the minerals in the water is reduced allowing the minerals to aggregate and form nano-sized colloids which remain in suspension rather than precipitate on pipes and associated equipment. Zeta potential is considered to be the electric potential of the minerals in the water. Aqua Conditioners lowers the Zeta potential of water by a factor of almost 2.

Iron Removal Media - Green Sand

Manganese greensand is a purple-black filter media used for removing soluble iron, manganese and hydrogen sulfide from well water supplies through oxidation and filtration. It also has the capacity of removing radium and arsenic. It is processed from the mineral glauconite that is zeolite. Using iron exchange properties of this natural zeolite, a manganese dioxide coating is deposited on the surface of the glauconite grains. The manganese dioxide acts as a catalyst in the oxidation-reduction reaction of iron and manganese. The media can be used in two methods of operations: continuous regeneration (CR) and intermittent regeneration (IR). Soluble iron and manganese are oxidized and precipitated by contact with higher oxides of manganese on the greensand granules. The hydrogen sulfide is reduced by oxidation to an insoluble sulfur precipitate. Precipitates are then filtered and removed by backwashing. When the oxidizing capacity power of the Manganese Greensand bed is exhausted, the bed has to be regenerated with a weak potassium permanganate (KMnO4) solution thus restoring the oxidizing capacity of the bed. 1 ½ to 2 ounces of potassium permanganate, in solution, per cubic foot of Manganese Greensand is considered sufficient for normal regeneration. It is required to vigorously backwash and regenerates the bed when it is placed in service and before its oxidation capacity is totally exhausted. Operating the bed after oxidation capacity is exhausted will reduce its service life and may cause stain. ADVANTAGES of Green Sand • Iron reduction over wide pH range • Effective reduction of hydrogen sulfide in addition to iron and/or manganese • No harmful effects from a chlorine feed • Low attrition for long bed life Green Water Concepts is a major supplier of Green Sand in Kerala

Activated Carbon

Activated carbon, also called activated charcoal, is a form of carbon processed to have small, low-volume pores that increase the surface area available for adsorption or chemical reactions. Those derived from coal and coke are referred as activated coal and activated coke respectively. Activated carbon works via a process called adsorption, whereby pollutant molecules in the fluid to be treated are trapped inside the pore structure of the carbon substrate. Carbon filtering is commonly used for water purification, in air purifiers and industrial gas processing, for example the removal of siloxanes and hydrogen sulfide from biogas. It is also used in a number of other applications, including respirator masks, the purification of sugarcane and in the recovery of precious metals, especially gold. It is also used in cigarette filters. Active charcoal carbon filters are most effective at removing chlorine, sediment, volatile organic compounds (VOCs), taste and odor from water. They are not effective at removing minerals, salts, and dissolved inorganic compounds. Typical particle sizes that can be removed by carbon filters range from 0.5 to 50 micrometres. The particle size will be used as part of the filter description. The efficacy of a carbon filter is also based upon the flow rate regulation. When the water is allowed to flow through the filter at a slower rate, the contaminants are exposed to the filter media for a longer amount of time. Green Water Concepts is one of the largest suppliers of activated carbon of different grades across Kerala.

Iron Removal Media - BIRM

Clack Birm® is a granular filter media commonly used for the reduction of iron and/or manganese from water supplies. Birm® is an efficient and economical media for the reduction of dissolved iron and manganese compounds from raw water supplies. It may be used in either gravity fed or pressurized water treatment systems. Birm® acts as an insoluble catalyst to enhance the reaction between dissolved oxygen (D.O.) and the iron compounds. In ground waters the dissolved iron is usually in the ferrous bicarbonate state due to the excess of free carbon dioxide and is not filterable. Birm®, acting as a catalyst between the oxygen and the soluble iron compounds, enhances the oxidation reaction of Fe++ to Fe+++ and produces ferric hydroxide which precipitates and may be easily filtered. The physical characteristics of Birm® provide an excellent filter media which is easily cleaned by backwashing to remove the precipitant. Birm® is not consumed in the iron removal operation and therefore offers a tremendous economic advantage over many other iron removal methods. Other advantages of Birm® include; long material life with relatively low attrition loss, a wide temperature performance range and extremely high removal efficiency. Negligible labor costs are involved because Birm® does not require chemicals for regeneration, only periodic backwashing is required. When using Birm® for iron removal, it is necessary that the water: contain no oil or hydrogen sulfide, organic matter not to exceed 4-5 ppm, the D.O. content equal at least 15% of the iron content with a pH of 6.8 or more. If the influent water has a pH of less that 6.8, neutralizing additives such as Clack Corosex®, Calcite or soda ash may be used prior to the Birm® filter to raise the pH. A water having a low D.O. level may be pretreated by aeration. Additions of chemicals to influent or backwash water which contacts Birm® media may inhibit iron or manganese removal or may break down or coat Birm® media. Chlorination greatly reduces Birm®’s activity. High concentrations of chlorine compounds may deplete the catalytic coating. Polyphosphates are known to coat Birm® and reduce Birm®’s ability to remove iron or manganese. Before adding any chemical to the influent or backwash water, the chemical's compatibility with Birm® should be thoroughly tested. Clack Birm® may also be used for manganese reduction with the same dependability as iron removal. In these applications the water to be treated should have a pH of 8.0-9.0 for best results. If the water also contains iron, the pH should be below 8.5. High pH conditions may cause the formulation of colloidal iron which is very difficult to filter out. All other conditions remain the same for either manganese or iron removal. Advantages of BIRM Media • Under the proper conditions, no chemicals to purchase for maintenance. Regeneration not required. • Iron removal efficiency is extremely high. • Negligible labor cost: only periodic backwashing required. • Durable material with a long life and wide temperature range. • Weighs only 40-45 lbs./cu. ft.
