Optimization of the cleaning effort

Advantages and disadvantages of short and long cleaning intervals

Table: 
Advantages and disadvantages of short and long cleaning intervals

Very short cleaning internals

 Very long cleaning intervals

High cost (operating costs)
High cost (subsequent costs)
+
Lower operational risk at full hydraulic performance capacity.
In the case of solidified deposits the cleaning result can only be achieved with high energy expenditures and a prolonged cleaning period.
+
Deposits cannot solidify; cleaning can be carried out with lower energy expenditure.
High operational risk because of limited hydraulic performance capacity.
+
Minimal risk of damage to pipelines due to lower energy expenditure during cleaning.
Increased risk of damage to the pipelines, as a result of
cleaning with maximum permissible energy expenditure.
