Textile Industry


Treated water through various processes is required to be employed in the textile sector like many other industry sectors. Serious problems such as spots or unobtaining the desired color will arise as a result of not using quality water, especially in painting processes. Elements such as iron, manganese, bacteria, organic matter and bicarbonate in raw water with undesired parameters like hardness create serious problems in the textile industry during sundry processes such as sizing, washing, bleaching, polishing and particularly in painting. These problems can be eliminated only through the selection of an appropriately selected water treatment system. The quality of treated water that must be provided in the textile industry is as below.


Appearance: Clear
Odor: Odorless
PH: Neutral
Hardness: <50 German hardness
TDS: <1 mg / l
Solids: <50 mg / l
Organic elements: <20 mg / l
Inorganic elements: <500 mg / l
Iron: <0.1 mg / l
Manganese: <0.02 mg / l
Copper: <0.005 mg / l
Nitrate: <50 mg / l
Nitrite: <5 mg / l
Bicarbonate: <50 mg / l
The most appropriate system should be chosen subsequent to comparison of raw water quality with the values specified hereinabove .



The quality of water used in textile processing industry is extremely important. A good deal of textile firms experience serious problems due to lack of appropriate quality of the water used. Some companies are not even aware that cited problems spawn from the bad quality of raw water. However, today, a considerable majority of the textile sector has begun to ascertain the necessity to improve the quality of raw water and bring same to the desired quality required through the textile industry and commenced to strive in parallel therewith. Members of textile industry, naturally, enter into dialogue with companies working in this field with an eye to achieve the water quality described in the previous section. At this point, it would be appropriate to underline the potential existence of a significant hazard that the textile industrialists may encounter with.

Various abuses are experienced incident to water treatment systems in our country as well as other various areas. Different methods germane to water purification technologies can be employed to achieve the same purpose. In order to recognize the most appropriate method all of these methods have to be examined thoroughly. Accordingly, companies in our country which are not aware of the basic facts incident to water treatment and which only can install reverse osmosis systems recommend only reverse osmosis systems to the textile industry as employed in other industries and thus do not allow the clientele thereof to examine and opt for other systems inasmuch as they cannot designate such systems. While reverse osmosis systems may be appropriate in some situations, there is a good deal of situations where resin system technologies are deemed fit and suitable.

Reverse osmosis systems in Turkey are generally implemented through companies which are not originally water treatment companies and which only can implement reverse osmosis systems. This said, companies approaching the issue as purchasing an ordinary machine suffer inconveniency due to slightest water problems thereof. There are dozens of systems in our country that do not work properly or create big problems due to falsely made pre-treatment (i.e. removal of iron, manganese, bacteria, organic matter, etc.) or on account of not replacing proper equipments that are required consequent to the implementation of a reverse osmosis system. Being a businesslike water treatment firm warrants conducting the soundest study of the analysis and establishing the most appropriate solutions. Another problem, as indicated hereinabove, is that the manufacturers which propose reverse osmosis systems as a solution for each situation are only capable of implementing cited system. Therefore what our industrialists need to carefully pay attention is that they have to choose the most appropriate technology after examining thoroughly rather than accepting the technology to be imposed thereto through manufacturers.

The main problems experienced in the textile industry rise due to water hardness and existence of bicarbonate. The amount of water used in textile industry is very ample. Therefore, the special resin systems designed by ARITIM MÜHENDİSLİK are able to provide more economical investment and operating cost compared to reverse osmosis systems. The system to be selected in textile industry has to be determined through a detailed study. In this sense, being a mere water treatment company is not sufficient. To know the properties of waste water disposed through the textile industry is a significant part of the subject issue. ARITIM MÜHENDİSLİK , thanks to18-year work experience thereof in environmental technology, namely in both water treatment and waste water treatment fields, can select the most appropriate systems incident to foregoing companies.

ARITIM MÜHENDİSLİK has the ability to design all the different technologies both in resin systems (ion exchange) and reverse osmosis systems and thus is able to prevent textile industrialists to purchase systems without being thoroughly aware germane thereto and hence make fatal errors respecting same.

ARITIM MÜHENDİSLİK is one of the leading companies on reverse osmosis systems not only in our country but also in the world. ARITIM MÜHENDİSLİK Water Treatment Systems, the patented brand of ARITIM MÜHENDİSLİK, that has made very successful implementations abroad in this field are sold in world markets. The world’s most energy efficient desalination system created through ARITIM MÜHENDİSLİK, which converts sea water to drinking water, is commercially available to end-users. Sea Water Reverse Osmosis System established in Cyprus with 1000 m3/day capacity, both technically and in terms of capacity, is one of the world’s most important facilities.

Last but not least, ARITIM MÜHENDİSLİK is the only Turkish water treatment company in the field of reverse osmosis that can take part in world’s largest environmental fairs in order to exhibit the products thereof. Not only reverse osmosis systems but also the ion-exchange systems aka resin systems were also exhibited in these fairs. This is simply because ARITIM MÜHENDİSLİK is a water treatment company to the core and able to produce duly all kinds of technology.

REMEMBER!!! There are always other alternatives for the water treatment system you are planning to install in your factory. Reverse osmosis system is only one of these systems, while the other one is the special ion exchange system. You must reach a final decision only after examining investment and operating costs of both systems. To this end, ARITIM MÜHENDİSLİK, with the ability thereof to design all cited systems, offers your esteemed side solution partnership vis a vis selection of your system in addition to mere sales of plant and machinery.

All issues mentioned hereinabove reveal how crucial and pivotal it is to work not with only a reverse osmosis company but rather with a water-treatment company and yet more with an Environmental Technology company while choosing your systems as a matter of fact.


We would like to provide your esteemed side with some information germane to Water Processing System of the company named TÜP MERSERİZE TEKSTİL SAN. TİC. A.Ş. which is one of the most notable facilities installed through us. TÜP MERSERİZE TEKSTİL SAN. TİC. A.Ş. Water Processing System has been established with a special tailor made ion exchange technology. The facility daily purifies 6000 m3 (250 m3/hr) well water and improves the quality thereof for employment of same in the textile industry (in order to obtain this amount of treated water with Reverse Osmosis system filtered water, 8000 m3 of raw water has to be used. 6000 m3 of treated water is obtained while 2000 m3 of cited amount is discharged as waste water.) However, the system installed through us currently converts 6000 m3 brackish water into 6000 m3 of treated water.

The treated water pH of the system is 6.95 to 7.05 and an extremely a homogeneous value is provided. Bicarbonate is 40 ppm as CaCO3 and French degree of hardness is lower than 0.2. Hence, extremely high-quality water is obtained for the textile process.

When the operating cost of the system is examined it can be observed that power consumption is almost non existent. Inasmuch as very high-pressure pumps are not required as in Reverse Osmosis system, the mere consumption of electricity is the one required for the regeneration pumps running only several hours a day.

HCl and NaOH are consumed as chemical elements in the system. HCl is used for regeneration and is not thrown away after regeneration but sent completely to waste water treatment plant. Inasmuch as the pH value of waste water employed in textile industry is 11 to 12, it is used in order to reduce the pH value of HCl wastewater used for regeneration prior to entry thereof to biological treatment. Thus, the regeneration cost of the system is zero. Neutralization of the water coming out of the ion exchange system is performed through NaOH. 500 Kg of 50% caustic is used per day to this end. The cost of caustic is 0.1 Euro/kg. This said, process cost of treated water per m3 has an extremely small price like 0.0083 euros in an ion exchange system with a capacity of 6000 m3. Daily cost of caustic is 50 Euro.

The cost of 1 m3 of treated water is 0.1 to 0.15 Euros in Reverse Osmosis systems. In this case, daily saving is well over 500 Euros per day.

To be able to implement only Reverse Osmosis system is now insufficient regarding the current requirements of textile industrialists. It is crucial to have the ability of establishing any type of water treatment systems. Even this is insufficient. Being capable of installing each type of waste water treatment systems allow industrialists to earn large profits through operation of the systems in integration.
