With the grown up industries the wastewater is increasing but not only this the sewage is contaminated with the left of whey from dairy production. Because they can't treat it further more or reuse it somehow from the last product of the dairy the cheese curd.

Although advanced novel approaches for the utilization of whey have been made recently, about half of all the whey produced is discarded. The total annual production of lactose, the chief constituent, is 4 million tons, of which only about 0.2 million tons (5%) find some commercial application. In future, tighter environmental controls for dumping whey are expected these could make disposal very difficult, if not impossible. Moreover, as the demand for cheese rises, whey production will increase, but the demand for whey and lactose will be greatly exceeded by what is produced. Therefore, their safe and effective disposal, protecting both the environment and the economy of the industry, is a large and imminent challenge for scientists.

All the fields lead me to have interest on it knowing that if we don't do nothing for our environment to improve it today then we will get the punishment for what we weren't able to do in the past. My interest fields are water and wastewater treatment, industrial waste and food waste but one process that must done today in my country is what to do with the industrial waste? By managing that many things will take place cause many of this waste considered like sewage and wastewater, if is not discarded on the sewage it's discharged on the lakes, rivers so they will affect the lake fauna by poisoning them through faster decomposable products that lead to different toxic substances and because the whey is a very acidic 5.6.5.9 pH it is a harmful waste if it is not treated.

So, if we don't give the right attention to this harm industrial waste, will keep flowing to other places taking the whey with itself, means that there are abundance of problems that indicate a lot of water, soil and also the most sewage treatment process will be harder cause the whey is a very concentrated product of a typical cheese whey, whether sweet or acid, contains lactose (3.3-6.0%), protein (0.32-0.7°/0), fat (0.15-1.0%), and traces of salts. The protein consists of P- lactoglobulin (50%), a-lactoalbumin (25%) and other proteins (25%), including immunoglobulins. The lactose and proteins are both potential biochemical sources and pollution problems. So depend on the whey content we can see how harmful she is to be drained also in the land and water systems of the city in my country special is the first think that comes up in industries. Whey is the major by-product of the dairy industry, which is produced in large quantities and usually disposed off causing major environmental pollution, due to its high organic load. The objective of this work is a development of a new pretreatment and transformation of whey residues into useful organic compounds.
