Textile wastewater includes a large variety of dyes and chemicals additions that is a huge environmental challenge. Main pollution in textile wastewater came from dyeing and finishing processes. These processes require the input of a wide range of chemicals and dyestuffs, which generally are organic Compounds of complex structure. Textile wastewater is a mixture of organic pollutants like carbohydrates, fats and oils, dyestuffs, phenols, detergents, & inorganic pollutants like acids, alkalis, metals, other salts, phosphates, nitrates, bleaches, sulphides, etc. Most of the chemicals are toxic and some are even carcinogenic and mutagenic. The color of the wastewater is basically due to insoluble and non biodegradable dyes. Conventional oxidation treatment i.e. chlorination have found difficulty to oxidize dyestuffs and complex structure of organic compounds at low concentration or if they are especially refractory to the oxidants. The use of ozonation in textile waste water treatment has proved to be very efficient and effective in removing color. Ozone is effective in removing the color from all dyes used in textile processing. Ozone is capable of causing the degradation of dyes.

Maintaining the chemical balance in any swimming pool is essential for clean and healthy pool water. Water balancing is not such a complicated exercise. It is simply the relationship between different chemical parameters. You will probably not change the water in your pool for many years. A pool that is "balanced" has proper levels of pH, Total Alkalinity, Hardness and Residual Chlorine etc. therefore Swimming pool water requires daily tests of this water parameters to maintain the water balance. A pool tester is a pool care system that enables the operators to find out the disinfection level in the pool.

DM Plant is an Ion exchange technology used to remove salts (cations and anions) from water. Soluble chemical compounds, when dissolved in water, become ionized; that is their molecules dissociate into positively and negatively charged components called ions. Consider common table salt, sodium chloride. In its solid form, this compound consists of one sodium atom (Na) and one chlorine atom (Cl) tightly coupled together (NaCl). When dissolved in water, however, the compound splits into two ions Na+ and Cl- A Typical two-bed DM Plant consists of two FRP vessels connected in series along with its internal fittings. The first unit consists of high capacity strongly acidic cation exchange resin, which converts positive ions of salt and replaces them with hydrogen ions to form respective acids, which are absorbed in next vessel by strongly basic anion exchange resin. The water obtained by this process shows conductivity less than 30 µScm and Total Dissolved Solids less than 10 ppm.Further high purity water can be achieved by Mixed Bed Deionizers, which are designed to produce high purity treated water. They can be used as polishing units after two beds DM Plant to obtain high purity water.

Aquaculture is the fastest growing food producing sector in the world. India is also one of the countries where eco-friendly aquaculture is going on. Understanding & identifying the physical and chemical water qualities are very critical for successful aquaculture. To a great extent water determines the success or failure of an aquaculture operation. The Objectives Of Today̢۪s Aquaculture Industries : Lower aqua culture mortalityIncrease size & weight of the aqua cultureReduce Fresh Water UsageMinimize Waste Water GenerationEnvironment Pollution Control Increase higher reproduction Rate with Effective Quality In general the fish̢۪s health depends not only on the inorganic waste but also depends on the organic & toxic waste present in the water. Traditionally chlorine is used as a disinfectant in aquaculture water treatment in order to control viral, bacterial, fungal or other pathogens which causes harmful effects on an aquaculture habitat. The residual chlorine even at low concentration is toxic to aquatic life and may require dechlorinationChlorine creates more hazardous by-products like tri halomethanes (THM̢۪s) All forms of chlorine are highly corrosive & toxicThe large concentration of chlorine doses may also oxidized skin surface of fish Fish becomes restless, lethargic, & may appear dead & have a shallow respiration Ozone is commonly used in aquaculture water treatment for two main reasons which are disinfection by the killing of harmful pathogens and a significant improvement in water quality. We are a trustworthy Manufacturer, Exporter and Supplier of Aquaculture Ozone Generator. Ozone is a powerful oxidizing agent disinfects and oxidizes organic pollutants while increasing the water̢۪s dissolved oxygen level. The end result is exceptional water quality, which is a fundamental requirement for intensive fish farming. Advantages Of Aquaculture Ozone Generator : It effectively removes organics, pesticides, discoloration, and nitratesTypically unconsumed ozone reverts back to oxygen, leaving no harmful residuals behindO3 improves the effectiveness of biological and particulate filtrationOxidizes organic matter such as fish excrementFish odor reductionPrecipitates dissolved solidsEnhances micro flocculation Disinfection Unlike agents such as chlorine, or any of its derivatives, oxidation with ozone leaves no hard to handle or toxic residues requiring subsequent complex treatment Ozone immediately starts to attack the oxidizable components it comes into contact with. This property makes it a very powerful disinfectant. Because the process only leaves "oxygenated" products No chemicals required for aquaculture treatment Increase shelf life of aquatic biota

Color in water and waste water is considered as pollution. There are two segments of waste water which can have color, one is domestic or commercial and other is industrial. Any waste water produced in commercial activity and domestic activities like grey water and sewage water can have less or high degree of color in their waste water. From industries like Food processing, PHARMA, Industrial effluent, Textile waste, Paper and pulp and Sugar industries can provide color in their waste water and if treated or disposed untreated becomes a major concern of authorities and society. Many times in spite of waste water treatment plant STP or ETP the treated water can have some objectionable color in the water. For this it is not commercially viable as well as technically feasible to install one more waste water treatment plant exclusively for color. Any color organic or inorganic in nature can be easily oxidized using strong dose of ozone in waste water. Ozone is very powerful oxidizing agent which cans easily being installed or retrofitted to reduce or to remove color from waste water. We have wide range of Ozonator from 10g/hr to 10kg/hr Ozone is very successfully used in tertiary treatment to reduce color from textile wastewater and treated sewage waste. It not only reduces color but also removes odor and disinfectant water.

During manufacturing and processing activity odorous gases are generated as a natural byproduct. It is many time an integral part of the process. Many time these odor are harmful and nuisance to people leaving in the surrounding areas. It can also be referred as air pollutions and demands scientifically designed and engage technology to control odor. Continuous expose or intermediate exposure to this odor can not only create nuisance but also some of ill effects like headaches, uneasiness, hypertension and illness related to air pollution. Odor is basically an organic or inorganic compound on molecules in air to reduce or remove the effect of odor it has to be efficiently oxidized. Ozone is one of the fast and strong oxidizing agents. Scientifically integrating ozone in air handling units or exhaust can oxidize foul odors can clean air. Odors are mainly associated with industrial processing and commercial establishments. There are many types of odors like industrial exhaust, sewage treatment plant, garbage areas, organic waste composting, fish feed industries etc.
