Necessity Of Oxygen Based Treatments In Wastewater Industry
Oxygen is one of the elements which can be vastly used in almost every industry, one of these industries being treatment of water and wastewater. It is quite easy to supplement oxygen to the process or simply replace the air with it, in the aeration basin. This allows the treatment capacity to be increased to its maximum limit along with reduction in VOC emissions, odour and foam. Furthermore, it also leads to increase flexibility of the process.
Wastewater is produced in almost every industry and every industry has to deal with the purification process as wastewater cannot be released into the environment. Now, adding oxygen is necessary as adding pure oxygen to the process raises the level of dissolved oxygen. Therefore, it reduces odours in water without requiring any further action. By creating oxygen acetates, the cost of the treatment system is significantly lowered. This allows every industry to meet its environmental goals without investing huge sums of money. This assists industries in managing peak demand by increasing capacity and reducing Volatile Organic Compound emissions at the same time. With the numerous developments in every process wastewater treatment plants are becoming a necessity in every industry. Therefore, use a trusted gas cylinder oxygen to reduce emissions of hazardous air pollutants. There are numerous In-situ systems which have been developed in a manner to allow combining the benefits of oxygen use in a low cost process, which is highly efficient and also reduces air emissions. Moreover, there is a significant reduction in minimal capital expenditure.
In the wastewater industry, it is quite difficult to find a disinfectant, however O2 gas cylinder can be utilized at this time, as oxygen is the best solution for removing a wide array of impurities from water. Oxygen is used for production of Ozone which is then used as disinfectant as it does not have any chemical residue. This is the main issue with most disinfectants as they all have chemical residue of some form. Therefore, it results in removing some impurities and adding its own residue as impurity, making Ozone the ideal disinfectant for wastewater treatment. The water released from these plants is not directly used anywhere, which is why when it let into the natural environment all its chemical impurities need to be removed completely.
Some advantages of using oxygen for treatment of wastewater, especially in the In-situ system are:
• Increase in bio-treatment capacity
• Considerably low Voc emissions
• Reduction in foam formation
• Controlled evaporative cooling effects along with electrical power costs
• Oxygen demand varies from time to time and the range of variations is fairly large
Additionally, oxygen is used for generating ozone, which is used for disinfecting water. Some of the processes in which oxygen is used are Odor control and aeration, pH control, disinfection and Ozone sludge reduction.
