Petrochemical wastewater treatment package
Before we discuss the Petrochemical Wastewater Treatment package or PCWW, let’s have a brief definition of the petrochemical industry and then we will discuss the various sources of petrochemical wastewater. Petrochemical is an industry that produces various chemical products with the help of raw materials from oil and gas. Due to such activity, it produces very dangerous chemical and toxic substances, which will cause irreparable damage to the lives of animals and humans if old methods of petrochemical wastewater treatment are used.
- Disinfection: in the last step before the purified water enters the spaces and fields For irrigation, etc., contamination by chlorine disinfectants or UV lamps, as well as ozonation They disappear. This method does not bring environmental risks, especially the purpose of Purified water during the petrochemical wastewater treatment process for irrigation of agricultural lands contains Edible trees.
API The American Petroleum Institute or API method is one of the old and relatively common methods in petrochemical wastewater treatment, which operates based on the standards of this institute. The most important difference with the CPI grease trap is that the tanks are rectangular and the solid and suspended particles of fat and oil are collected based on the specific weight, which of course is affected by the wind due to being open, and after settling each of the components from They separate from each other.
DAF, DAF or Dissolved Air Flotation degreasing method in petrochemical wastewater treatment, which is the newest and best known degreasing method, which is used not only to separate solid particles and oil and its suspended derivatives, but also to reduce the rate of various pollutant parameters such as BOD5 and COD decreases. In this method, high pressure air flow is injected into the water that needs to be treated as petrochemical waste water, and the suspended matter adheres to the air bubbles that are formed and quickly rises to the surface.
All these methods are among the best and most effective methods of degreasing in the treatment of petrochemical and other industrial wastes by Ati Sazan Arsham Sanat Group. It should be noted that Ati Sazan Arsham Sanat Company, having all the devices and equipment related to petrochemical wastewater treatment, is considered the largest supplier and provider of this type of service in the country.
IFAS IFAS or Integrated Fixed-Film Activated Sludge method in petrochemical wastewater treatment with the help of activated sludge technology increases the efficiency of treatment even for downstream processes and its fixed film substrate is completely resistant to organic substances and hydraulic shocks. This method, in a way, is a combined method with the advantages of both, and the fixed film bed is placed inside the activated secondary sludge during the industrial wastewater treatment process.
EAAS is the EAAS or Extended Aeration Activated Sludge method in the treatment of petrochemical wastewater for those times when a much higher efficiency is considered from the purification and recycling of activated sludge by aerobic and biological methods, which consists of two stages. In the first stage, for the decomposition of sludge and also for the reproduction of bacteria, organic materials are decomposed, but their amount is small, therefore, in the second step, in order to provide energy, the bacteria not only decompose the sludge, but also use the organic materials of their structure and They occur almost simultaneously.
UASB UASB or Up-flow Anaerobic Sludge Blanket method works much more successfully in the treatment of petrochemical wastewater in removing BOD and COD, and more methane gas can be obtained from the recycling of activated sludge, and at the same time, a system to prevent the emission of odor is also considered for it. Is.
