The presence of iron and manganese in the water supply is clearly distinguishable by the presence of brown/yellow staining on clothing & sanitary wear.

Watercare offer a range of filter systems to eliminate iron and manganese from the water supply.

1.      Automatic backwashing column filter system using a Birm media. Birm is an efficient and economical method of removing dissolved iron and manganese compounds from raw water supplies. It acts as an insoluble catalyst to enhance the reaction between dissolved oxygen and the iron/manganese compounds. When using Birm for iron removal it is necessary that the water contains no oil or hydrogen sulphide, organic matter does not exceed 5 ppm, the dissolved oxygen content is at least 15% of the iron content and the pH is 7 or higher. For manganese removal the above also applies but the minimum pH is 8.0.

2.      Automatic backwashing column filter system using manganese greensand media.  Manganese Greensand is capable of removing iron, manganese and hydrogen sulphide from water through oxidation and filtration. Soluble iron and manganese are oxidised and precipitated by contact with the greensand granules. Hydrogen sulphide is eliminated by oxidation to the sulphate form. Precipitated material is removed by back washing and the oxidising power is restored by regeneration with weak potassium permanganate solution.

3.      Automatic backwashing column filter system using an ion exchange resin media which regenerates using granular salt.  This system removes iron, manganese and hardness

4.      Automatic backwashing column filter using crystal rite media which regenerates using granular salt.  Crystal rite provides superior removal of iron, manganese & hardness while raising pH levels of acidic water at the same time.  Crystal rite crystals provide better filtration and are thoroughly cleaned by backwashing faster than ordinary resins without loss of product.

Crystal Rite is available in 2 forms

a)      Crystal Right 100 is used where the raw water pH is between 6.0 and 7.0. (if the pH is lower than 6.0 then conventional pH correction will also be needed.)


Crystal Right 200 is used where the raw water pH is 7.0 or above, its advantage in this situation is a higher capacity.

 

The presence of hydrogen sulphide in the water supply is easily identified by a rotten egg like odour.  Watercare offer a range of systems to eliminate hydrogen sulphide as levels can vary considerably.

1.       Low levels of Hydrogen Sulphide can be removed by the installation of an Activated Carbon column filter. Activated Carbon is for use in a range of water treatment applications. Typical uses include taste and odour removal in domestic water treatment.

2.      Moderate levels of Hydrogen Sulphide can be removed using Manganese Greensand. Manganese Greensand is capable of removing hydrogen sulphide, iron and manganese from water through oxidation and filtration. Hydrogen sulphide is eliminated by oxidation to the sulphate form. Soluble iron and manganese are oxidised and precipitated by contact with the greens and granules. Precipitated material is removed by back washing and the oxidising power is restored by regeneration with weak potassium permanganate solution.

3.      High levels of Hydrogen Sulphide can be removed using an Aeration (non chemical) system.  An Aeration system comprises of a) an aeration tank b) an aeration spray system c) booster pump d) Activated Carbon column filter.  This process involves the water being supplied to the aeration tank from the well pump via aeration nozels fitted in the tank.  This allows the water to be exposed to the atmosphere resulting in the dissipation of the Hydrogen Sulphide.  The water is once again pressurised by the use of a booster pump which supplies water to the property via an Activated Carbon filter

4.       Excessively high levels of Hydrogen Sulphide can be removed using Ozone (non Chemical) {link to Ozone page}

pH - Acidic Water
 
Water particularly is some mountainous areas, may have very low pH values, low hardness values and excess of carbon dioxide.  This situation causes corrosion phenomena and oxidises depositing, as a consequence the perforation of pipes.  The solution to the problem is installing neutralizing filters with calcium carbonate.  Neutral neutralising filters made up of a column containing active masses of calcium carbonate capable to increase the pH value and the water hardness, bringing it to a more balanced value.  The masses need to be periodically washed, this is automatically carried out by the head of the column filter controlled by an electronic timer.  To complete the protection of the systems, it is necessary to install after the neutraliser a metering pump for dosing an anti-corrosion product. 

The quality of potable water is periodically kept under control by the public corporations in charge, but this does not avoid the risk of leakings and pollutants along the supply pipelines that are often too old.  To be sure of the quality of the water coming into our houses, the water we daily use to cook our meals, a valid solution is installing a UV sterilising system.

With the installation of a UV disinfection system you no longer have to be concerned about waterborne pathgenic organisms causing illness or contaminating production processes.  UV systems kill bacteria, viruses and other pathogens by preventing them from reproducing.  The results? Safe drinking water.

UV disinfection is a natural process that adds no chemicals to your water.  Other disinfection methods, such as those that use chlorine, may create harmful chemicals that have been linked with serious illnesses

Maintenance Looking after your UV system is easy.  All you have to do is periodically clean the lamp sleeve and replace your lamp once a year. Watercare can provide peace of mind warranty packages.

Various types & models are available to suit your particular applications e.g household/industrial

_Most municipal water supplies contain chlorine, chlorine levels vary because of uneven distribution.  Water can contain excess of chlorine used for disinfecting, cause of bad smells, colours, unpleasant tastes and possible formation of compounds dangerous for the human health.  For this reason it is recommended to install a chlorine removal filter with activated carbons.

_The presence of nitrates in water is caused by the decomposition of nitrogenous substances that can be found in human or animal waste and mainly by the indiscriminate use of (nitrogen-based) fertilizers in agriculture.  These fertilizers are being more & more used and high concentrations can be found particularly in water beds and in all agricultural areas strongly overworked.  Children under six-seven years old and elderly people are more subject to the risk, directly affecting the blood composition, thus reducing haemoglobin and giving origin to carcinogenic processes.  For domestic use it is recommended to reduce the excess of nitrates by installing a nitrate remover with anionic resins regenerate by sodium chloride.

_Various levels of ammonium can be detected in ground water.  Ammonium found in ground water supplies can be removed successfully by the installation of an automatic backwashing column filter using crystal rite resin & chlorine generator.  This system regenerates using granular salt
