With the expansion of cities and the increase in the need for water supply, the population living in these areas has increased significantly, and of course the amount of wastewater generated has also increased. In order to supply water, there is a need for large treatment plants with different structures such as reservoirs and basins for purification, sedimentation and storage.
In the wastewater industry, just like water supply, it needs various basins to separate and secure the outgoing wastewater. Usually, all over the world, basins are made of concrete structures for financial and work reasons.
Although the construction of water and wastewater basins with concrete has its own advantages, but because both water and wastewater have factors that can greatly aggravate corrosion and damage in concrete, in most cases, concrete water and wastewater basins work much less than the service life of their design and need to be modified and repaired.
Two important factors in the corrosion and damage of concrete water and wastewater basins are more important than others. The first factor is the very different acidity of the fluid inside the reservoir, which varies according to the source of the water and the water entering the basin.
If the water input is from areas where the salts in that area give the fluid an alkaline or acidic effect, then surely, due to the high reactivity of concrete with these materials, corrosion will start on the surface and corners of the reservoir and penetrate into the thickness of the structure.
This case is much more severe in wastewater basins because the wastewater input from industries and residential units is very acidic or alkaline and the severity of their damage is much higher than water.
After the first factor, in general, the creation of sulfur factors causes the bad smell of wastewater and is the main factor in reducing the strength of concrete basins in this industry. The chemical agent H2S, which reacts in the vicinity of other metals, can create much stronger acids, which further causes damage to the basin.
Considering all the mentioned cases which are the main destructive factors in this industry, Farasath Zarfam Company has entered the field of strengthening and repairing concrete water and wastewater basins and by providing the latest method to prevent and improve the performance of concrete water and wastewater structures that are used It is one of the various composite coverings, which has taken steps to preserve the capitals of different employers.
By conducting various researches in this field and rooting out the main factors involved in creating defects and damages in concrete basins, Farasath Zarfam Company offers its composite coatings for various functional conditions of water and wastewater that meet the needs of the respected employer.
The materials used in the construction and application of the mentioned composite coating are used according to the acidic or basic conditions, the amount of acidity, the amount and type of damage caused, the desired strength and the length of service based on global standards.
In addition, the implementation of the composite coating is applied after the design and supply of materials by Farasath Zarfam Company, using guidelines based on each project.
Farasath Zarfam Company is ready to provide consulting, design and implementation of such projects in various industries by implementing several successful examples of repairing concrete water and wastewater basins using composite coating in industries such as oil and gas.
