  • industrial wastewater control systems

Since the nature of wastewater produced by the four producing subsidiary companies differs, various methods of treatment are required to cope with the issue. There are 21 pre-treatment or full treatment systems installed at the complex with a total treatment capacity of fifty thousand cubic meters a day. Their specifications are as follows:

Systems Units
DAF (Dissolved Air Flotation) 3
CPI (Corrugated Plate Interceptor) 4
API & PIT 8
Activated Carbon 1
Neutralization 6
Ion Exchange 1
Oil Baffle 1

 

There is a project in progress for re-treating and recycling of all treated wastewaters.

 

Waste Management

Waste Quantity and Quality Evaluation Project

Study of current situation/ identification of sources of industrial and municipal waste/ quantity and quality study of waste materials/ waste materials classification/ proposing solutions to improve waste management.

 

Executed improvement projects: at this stage, projects that have led to improvements in waste management, be it reducing the volume and quantity of waste materials, reducing contamination due to waste treatment or improvement in treatment methods are as follows:

Building a site to recycle municipal waste
Designing and building the country’s first and only industrial landfill
Coding waste materials
Preparing special containers for waste materials transportation
Constructing separation and storage site for metal and wooden waste
Cutting transfers to the burn pit to reduce environmental pollution
Installing an automated system to order and record waste transport work orders
General training for personnel
Specialized training for the environment division staff

 

BIPC Landfill

The center has three waste burial cells of the level type known as Area Method. As an example, the cell number 2 is for the burial of half-hazardous and hazardous solid waste. It has the following specifications:

  • Dimensions 176×86 m
  • Compacted clay improved with bentonite of 90 cm diameter
  • HDPE Geomembrane coverage of 2 mm thickness
  • Geotex tile for protecting geomembrane
  • Drain with 15 cm thickness (coarse-grained and rounded corner so that it is more porous and penetrable for the leachate)
  • Four polyethylene pipes each one of 25 cm diameter and 90 meter length

Another example is the cell number 3 allocated for the high hazardous waste. It has the following specifications:

  • Dimensions 42×42 m
  • Compacted clay improved with bentonite of 90 cm diameter
  • HDPE geomembrane coverage of 2 mm thickness
  • Clay layer of 10 cm thickness for protecting geomembrane
  • Drain columns of 30 cm diameter thickness at the distance of 1o meters
  • A drainage polyethylene cell of 25 cm diameter and about 50 meter length

 

Leachate collecting Cells

Eight small cells gather leachate and rain water from drain systems of waste burial cells.

Two main cells gather and lead the leachate to evaporation pond.

The evaporation pond is designed to store leachate and rain water before they are evaporated.

BIPC Waste Incinerators:

  • Ab Niroo Company Solid Waste Incinerators
  1. Incinerator number 1 for burning polymers
  2. Incinerator number 2 for burning industrial waste such as bags, clinical infectious waste, poisonous material containers and work clothes

These two-story incinerators work with hydraulic systems. The waste materials are burnt in the first story in 800 to 1000 degrees Celsius. Afterwards, the hydrocarbon residue of burnt polymers is transferred to the second story that does the combustion in 1000 to 1200 degrees Celsius.

 

  1. Kimia Bandar Imam Company Liquid Waste Incinerator

Heavy and light Chlorinated hydrocarbons are burnt at the VCM plant waste incinerator at about 1200 degrees Celsius. In this system, a scrubber tower is designed to neutralize the remaining Cholridric acid gas, preventing it from exiting the system. It neutralizes the emitted steam through injecting water and caustic.

3-3 Controller equipment of atmospheric pollutants

To control the atmospheric pollutants there are installed 10 scrubbers of various types, 46 cyclones and 6 Flare Systems of different types. Moreover, a project is executed for evaluating the quantity and quality of atmospheric pollutants, having done the modeling and planning of dissipation of these types of pollutants. Continuous Emission Monitoring (CEM) is installed on all stacks.

 

Landscapping activities

  1. Creating a mangrove forest through planting eight million trees in a land of 500 hectares
  2. Building a 68-hectare park in Mahshahr city
  3. Creating a 30 hectar green landscape inside the complex
  4. Building a cultural-recreational complex close to the Salt Lake
