Water Filtration

Description Specification Downloads General Description Water with a pH below 7 is acidic and has a corrosive nature. Acidic water corrodes the copper pipe-work and heating systems found in domestic and industrial plumbing systems. The copper dissolves out and is deposited on fixtures and fittings leaving unsightly green stains. Raising the pH will neutralise the water stopping the corrosivity, removing the metallic taste. The simplest way to raise the pH of water is to pass the water through a vessel containing slowly dissolving calcium and magnesium salts. These salts slowly dissolve into the water 're-mineralisingƒ?? the water and naturally raising the pH. The water can be simply passed through the media through an in/out head or through an automatic backwashing filter head. The backwashing head has the advantage of remixing the media and also removing any debris which may have been oxidised out of solution as the pH increases.

Colour in water (after it has been mechanically filtered) is typically caused by organic compounds. If the colour is due to iron or manganese there are specific treatments (see the iron and manganese section). If the colour is due to organics then treatment is normally by ion exchange or activated carbon. Organic colour comes from decaying vegetation and may be completely soluble or particulate. Tannins (Humic and Fumic acids) are by far the most common class of compounds and give the water a yellow/brown tint. In highland areas where water runs off peat the water can be heavily coloured. When the water passes through anion resin beads the organic molecules are bound to the resin. When the resin has become saturated and can hold no more colour forming compounds they need to be removed. Resin selection is critical as many require caustic soda to remove the

Description Specifications Downloads The 3 Series ECO UV system is designed specifically with the environment in mind. Longevity: The 3 series ECO system is designed primarily for longevity. The system is manufactured to be very robust as it is manufactured from stainless steel throughout. This should last upwards of 20 years with only minor components possibly having to be replaced. Even when the system has come to the end of its useful life, all components can be easily recycled. This gives the DaRo UV systems 3 series ECO a very low overall carbon footprint. 5 year warranty: We believe that no other manufacturer confidently backs their UV Systems with such a pioneering manufacturerƒ??s warranty. With impressive build quality and assured design you can be guaranteed complete piece-of-mind** UK manufactured: The DaRo UV systems 3 series ECO is manufactured throughout at a single facility in the UK, unlike many other systems that are shipped in from the Far East, thus lowering
