“A PROCESS OF TREATING SEA WATER FOR USE IN TEXTILE PROCESSING UNIT”

The following specification particularly describes the invention and the manner in which it is to be performed
BACKGROUND
[0001] The present invention relates to sea water treatment and more particularly, to a process for the treatment of sea water to produce water suited for use in textile processing.
[0002] One of the most important resources on earth is water and is an absolute requirement for sustenance of life on the planet. Water is consumed by all living beings and especially used by people for home and industrial purposes. While the supply of sea water is abundant, fresh potable water on the other hand is limited. Without conservation efforts of our fresh water resources, this vital supply of potable water may be exhausted.
[0003] Conservation carries economic benefits as well, as energy and equipment are also conserved as a direct result of water preservation efforts. Conserving water is important because it keeps water pure and clean while protecting the environment. In a recent study, it is found that 3% of the earth's water is fresh water, 2.5% of the earth's fresh water is unavailable which is locked up in glaciers, polar ice caps, atmosphere, and soil, highly polluted, or lies too far under the earth's surface to be extracted at an affordable cost. 0.5% of the earth's water is available as fresh water.
[0004] The textile industry uses fresh water to treat their fabric or garments. In textile wet processing, water is used mainly for three purposes, namely, as a solvent for dyes and chemicals, as a medium for transferring dyes and chemicals to fabric, and as a washing and rinsing medium. However, the water used in the textile industry is fresh water. Sea water which is abundant is not used in the washing process of textiles as it known to destroy the fabric as well damage the processing machines.
[0005] Therefore, there is a need to use sea water in the textile industry while ensuring no damage occurs to the textiles or machinery.

[0013] FIG. 1 schematically illustrates one process by which sea water is treated to form textile compatible water, according to techniques of the present invention. Each step of process 100 is described in further detail below.
[0014] At s sea water is filtrated in order to remove one or more living things such as aquatic organisms, small fishes and the like. Further, the sea water is filtered to remove sludge and several other small objects such as seashells, pebbles, etc. In one embodiment, the filter used for the filtration process is a 200-micron nylon mesh filter. In one embodiment, the filtered sea water is stored in an open tank.
[0015] At step 120, silver nitrate (AgNo3) is added to the filtered sea water to remove chlorine and reduce the saltness of the water. The filtered sea water, typically includes 25 to 35 grams per litre of dissolved NaCl (common salts) and other dissolved salts of magnesium, potassium, calcium etc.. In aqueous solution Sodium and Chloride is present in the ionic form. In an example embodiment, 15-25 gram of silver nitrate (AgNo3) id added per litre of filtered sea water. Silver Nitrate reacts with sodium chloride chemically to produce a precipitate of silver chloride after 30-45 minutes. It may be noted that when chlorine is removed from the sea water, the saltiness of sea water is reduced drastically. In one embodiment, the precipitate is removed through lower valve of the tank.
[0016] At step 130, capric acid is added to the above treated sea water to entrap metal ions and to create complex salt. The capric acid is a fatty acid and therefore entraps metal ions in its long chain to create metal complex salt. In an example embodiment, the amount of capric acid added is 30-35 grams per litre of the treated sea water. The capric acid is mixed with the treated sea water for about 20-30 minutes. The capric acid also lowers the PH of the treated sea water. In one embodiment, the pH of the treated sea water is between should 5.5 and 7. If the pH of the treated water is still acidic, it can be adjusted by by adding soda ash or any base component.
[0017] At step 140, the treated sea water from step 130 is passed through an activated carbon filter. The activated carbon filter traps and removes the complex salt and softer water is generated. The activated carbon filter can also remove, amongst other things, herbicides, pesticides, organic contaminants, and chemicals such as chlorine. In an example embodiment, the activated carbon filter has a large surface area with tiny, low-volume pores thus providing a surface for either absorption or chemical reactions.
[0018] At step 150, the filtered sea water from the above process is passed through a positive sodium ion charged ion exchanger. In this step, the ion charged ion exchanger replaces magnesium and calcium ion to sodium ions which are attached to a resin. The final treated water retrieved from the step is compatible for use in textile processing.
[0019] Thus, it can be seen from the above process, sea water that is abundantly available, can be used as a resource for textile processing units. This helps in conserving fresh water and thus is an environment friendly process.
[0020] The present invention has been described above by way of example. However, the present invention is not limited to the above specific embodiments. Any changes or modifications made based on the present invention fall within the protection scope of the present invention.
