Industrial wastewater is a by-product of the manufacturing of commercial products. Industrial products may produce hazardous runoff from the operating equipment. This wastewater needs to be treated before being dumped into the sewer or wastewater stream.
The treatment guidelines are governed either by state or federal regulations. These need to be complied with to avoid any penalties. The wastewater treatment process is much dependent on the chemicals and their storage.
The chemical storage tanks should be designed properly to avoid any leaks and spillovers. In case of the system failure, not only the employees are harmed but the industry itself could be shut down.
Role of chemicals in Industrial Wastewater Treatment:
- Neutralization: During this process, sulfuric acid sodium hydroxide is added to the water to achieve the optimum pH.
- Removal of solid particles: To facilitate it, chemicals such as ferric chloride, alum, and other flocculants and polymers are used. These generate a positive charge to neutralize negatively charged solid particles.
- Odour control: The accumulation of wastewater generates some unpleasant odours. Certain chemicals are required to reduce the foul smells.
- Disinfection: Disinfectants are needed to remove the pathogens from the wastewater.
- Sludge treatment and removal: A polymer chemical is used to remove water from the sludge. This reduces the volume significantly, making transporting the sludge to the landfill easier and less expensive.
Reliable chemical storage depends on several factors such as the type of industry, size of the business, and federal, state and local legislation.
Choosing the ideal chemical storage tank:
Wastewater treatment requires aggressive chemicals to treat the water. Thus, it becomes pertinent to store them safely.
Generally, the facility planners give priority to space rather than the particular needs, while designing the tank.
The chemicals used in industrial wastewater treatment chemicals require a strong and safe storage solution to combat their corrosive properties and other harmful effects.
Different types of chemical storage tanks are:
- Fibreglass: Fiberglass storage tanks are constructed of wound strips that overlap or are sprayed on fibreglass material. This forms several seams. However, each seam serves as a weak link that provides another opportunity for a leak or tank failure. It is also expensive and requires additional corrosion barriers for aggressive chemicals. It raises the overall cost of the tank. If you are thinking of purchasing a fibreglass tank, be prepared for ensuring regular inspection and maintenance.
- Linear and Cross-linked Polyethylene: Though less expensive than the fibreglass tank, the linear polyethene tank is also less robust. However, cross-linked polyethene tanks are cost-effective, resistant to chemicals and robust. They are seamless and have one-piece moulded construction.
The right chemical storage tank becomes a crucial part of the industrial wastewater treatment process.
