Particulate filtration is the filtering of solid, undissolved particles from water. The nature and size of solid particles can vary greatly. Some examples are clay particles, sand, organic debris, Iron oxide and Manganese oxide. Particulate filters can be used whether on their own, or more commonly, as part of a filtration system. Iron and Manganese filter systems for example sometimes use a back washable particulate filter. The type and size of filter will depend on the water quality and flow rate. We can offer assistance in this area.

Reverse osmosis is a process that is used to remove a wide range of salts to give water of a high purity. Osmosis is a natural process involving fluid flow across a semi-permeable membrane barrier. It is the process by which nutrients feed the cells in our bodies and how water gets to leaves at the top of trees. If you seperate a solution of salts from pure water using a basic thin semi-permeable membrane like a sausage skin, the pure water passes through the membrane and tries to dilute the salt solution. If the salt solution is connected to a vertical pipe then the progressively diluted solution will fill the pipe until the osmotic pressure drawing the pure water through the membrane is the same head pressure as the diluted solution. We can offer assistance in this area.

The RO/EDI unit uses electro-deionisation to further polish the RO water, producing water with a typical quality better than 10 Meg Ohms. The EDI contains alternating semi-permeable anion and cation exchange membranes. The spaces between the membranes are configured to create liquid flow compartments with inlets and outlets. A transverse DC electrical field is applied by an external power source using electrodes at the ends of the membranes and compartments. When compartments are subjected to an electric field, ions in the liquid are attracted to their respective counter-electrodes. The result is that the compartments bounded by the anion membrane facing the cation membrane facing the cathode become depleted of ions and are thus called diluting compartments. The membrane facing the anode will then trap the ions that have transferred in from the diluting compartments. Since the concentration of ions in these compartments increases relative to the feed, they are called concentrating compartments, and the water flowing through them is referred to as the concentrating stream. We can offer assistance in this area.

Yellow discolouration of water can be caused by organic compounds called tannins. These are usually found in peaty areas and in water supplies that are affected by surface water. Apart from discolouration, organic compounds can make water unpotable and can foul filtration and reverse osmosis systems. We can offer assistance in this area.

Activated Carbon is a specialised filter media used principally for removing Chlorine or organic compounds from water. Most of the activated Carbon used for water treatment is made from baking crushed coconut shell until it produces a charcoal type material. This is then activated with high pressure steam, leaving the carbon with many minute active pores on its surface. The ability of Activated Carbon to remove contaminates from raw water is dependent upon the length of time the water spends in contact with the media. Therefore sizing the filters correctly is crucial for effective performance. We can offer assistance in this area.

The presence of Nitrates in water causes many problems, ranging from blue baby syndrome (if fed to babies less than 6 months old) to contamination of poultry if used as feed water for farmed birds. The source of Nitrates in ground water is usually from farming fertilisers. The EEC permitted maximum is50mg/l with an advisory maximum of 25mg/l. We can offer assistance in this area.

Private water supplies may contain micro-organisms that can be harmful if consumed. Ultra Violet light is electromagnetic radiation with a wavelength that is shorter than visible light but longer than x-rays. This disrupts the DNA of micro-organisms, preventing them from replicating and thus de-activing their potential for infection. Ultra Violet systems provide a safe, clean and economical method for sterilisation of water supplies. We can offer assistance in this area.
