Water purification plants for washing industrial vehicles tanker trucks
The washing of tankers and industrial vehicles in the last decade has been completely revolutionized, the European community to ensure the conformity of products transported in tanks and to avoid any contamination between products, has included a regulation and the creation of a certificate of “suitability for washing”.
This has allowed the creation of a new industrial sector such as the washing of tankers and industrial vehicles.
This industrial washing process produces a considerable amount of wastewater with very different chemical, physical and biological characteristics both in concentration and type.
Every single washing of a tanker truck produces a wastewater that is composed of the product previously transported, for this reason it is necessary to study specific water treatment plants that pay attention to the chemical diversity that intertwine during the different washings.
Pentacque, thanks to its experience, is able to advise you and provide you with purification plants that correspond to these needs, these water treatment plants in some cases are defined as complete, which means the purification consists of a chemical-physical treatment and a biological treatment.
The chemical-physical water treatment section, is highly effective and flexible, the purification plants we install must be able to treat waste water even with strong fluctuations in chemical concentrations, the water treatment plant must be able to absorb all the pollutants present.
This can be achieved thanks to PLC automation and stoichiometric dosing of the correct chemical contrast reagents, it also should be noted that this wastewater has a strong presence of suspended and sedimentable solids that require a preliminary flotation purification plant that reduces the COD and attenuates the entire subsequent purification process.
If the washing of tankers and industrial vehicles produces organic wastewater, as it conveys products that can be assimilated to the food industry, the wastewater treatment plant must be of the activated sludge biological type.
The sewage treatment plant normally used in case of food-grade contamination of the wastewater is a batch biological activated sludge treatment system, this solution is suitable because the low daily volumes and the diversity of pollutants are contained by this system.
It has to be considered that the treatment capacity in terms of yield, is greater than the continuous biological system, this batch sewage treatment system also suffers less from the lack and diversity of organic feed and is better able to withstand the variations caused by different washings.
The combination of chemical-physical and biological activated sludge batch plants are necessary in this area, the treatment designed ensures the functional guarantee and compliance with the current table limits.
The water treatment plants normally proposed in the washing of tankers and industrial vehicles are:
- Continuous chemical-physical purification plants
- Chemical-physical sewage treatment plants in batch
- Sludge dewatering plants
- Absorbent filtration equipment for surfactants and organic substances
- Biological plants with continuous activated sludge
- Automatic forced aeration batch installations
- First rain plants
