A method of dye removal from wastewater includes producing activated carbon from heavy oil fly ash and using the activated carbon to adsorb dye in the wastewater. The heavy oil fly ash based activated carbon is produced using phosphoric acid based chemical activation. The dye can be removed from wastewater by contacting the wastewater with the activated by: 2. Certain impurities in the waste streams to be treated by ion exchange, in addition to magnesium, such as lead and other metals, calcium hard- ness, etc., would be retained by the exchange resin and problems re- lated to regeneration of the resin and reuse of the zinc could be expected.
In general, the wastewater from textile industry contains many various dyes. To gain a widespread reception, the azo-degrading bacteria should exhibit decolorizing ability for a wide range of dyes, aeromonas hydrophila was selecte from six bacterial strains with the capability of degrading textile dyes (Chen et al, ).File Size: KB.

The objectives of this study is to demonstrate an automatic bench scale pilot unit using polymeric resins to remove dyes from textile wastes. The size and flow rates of the unit will be appropriately sized to obtain the ne- cessary data to ascertain costs and technical feasibility of a full scale re- sin exchange.

UF treatment is not widely used by the textile industry due to the low dye rejection , this is why, direct recycle of filtrate is not possible without further treatment.
Alves and Pinho  reported that UF is more suitable than reverse osmosis to decolourize the wastewaters supply by the tanning industry because the dyes are bound to fats. The use of low-cost adsorbent has been investigated as a replacement for the current expensive methods of removing dyes from wastewater.
As such, fly ash generated in National Thermal Power plant was collected and converted into a low-cost adsorbent. The prepared adsorbent was characterized and used for the removal of dyes from by: and the best available technologies (BAT) for their removal from textile effluents.
Textile operations and water pollution Textile industries prepare fibers; transform fiber into yarn and then yarn into fabric. Subsequently, these fabrics go through several stages of wet processing (Holkar et al., ). It is well known that adsorption by activated carbon is an effective and commercially applicable method for removing colour and other pollutants from textile and dye wastes.
Porter () suggested that carbon adsorption is a complete treatment for textile by: But due to high export demands of textile materials, textile producers are extensively using synthetic dyes. These synthetic dyes have complex aromatic structure which is resistant to light, ozone.

The use of synthetic chemical dyes in various industrial processes, including paper and pulp manufacturing, plastics, dyeing of cloth, leather treatment and printing, has increased considerably over the last few years, resulting in the release of dye-containing industrial effluents into the soil and aquatic ecosystems.
The textile industry generates high-polluting wastewaters and their. Dyes are widely used to colour products in textile, leather tanning, cosmetics, pigment and many other industries. Effluents discharged from these industries cause potential hazards to environment and human health.
Hence, the removal of dyes from water/wastewater has gained a huge attention in recent years. The service life of a resin will depend on a number of factors, including the chemical makeup of the stream to be treated, the type of IX process and resin used, how often regeneration cycles are needed, the hydraulic load of the resin, and whether any extreme process conditions exist.
IX resins degrade gradually with use, making it difficult.The patent-pending Nano-Dye TM turn-key system is designed with the strategic intent to use the textile dye plant’s current exhaust dye equipment and dyestuff library.
Nano-Dye TM ’s break-through dyeing technology now allows cotton exhaust dye jets to use no salt and exhaust up to 99% of dyestuff (eliminating solid waste).
