Another advantage of resin composite products is possibility to combine two or more products to each other in order to create a new product.
For example, a septic tank can be combined with composite manholes in the case of observing the entry liquid.
The composite septic tank has other advantages of resin composite products like: electricity resistance or avoiding UV from sunshine or FDA standard in storing water.
The new product is usable for clean up refinements where the tank is underground and needs to be observed.
The main process of tank is in two parts.
The first part that cleans water from oil and takes out the oil, outside of the tank.
Then the second part that takes big sedimentary form the liquid and take them out.
Those manholes were used in septic tank are useful when someone needs to observe the parts of cleaning up the liquid.
The manholes are installed on the top of tanks.
One of the places that needed such a product was Shiraz State Airport.
The organization needed the tank for their temporary refinements.
Matin Technical Design Co had done the project for Shiraz Airport as will be detailed below:
The tank was created in dimensions 1.6*3.4 with the height of 7m.
The main use of the tank was cleaning up the refinement underground.
