Wistrand continuously works with development of our procedure, in order to improve the technical result and to minimize influence on the environment.
A boiler with fewer operating hours since the last performed chemical cleaning, are normally easier to clean than one with twenty years of operation. It requires fewer steps in the treatment and the cleaning becomes less complicated and can often be performed with less consumption of chemicals. Which also means a smaller load on the external environment, as well as a shorter time time required for the cleaning.
Wistrand works according to an environmental and safety policy. When you contract Wistrand, you will always be sure that we will put safety and environment first.
If the chemical cleaning can’t be included of the normal “environmental conditions/terms” a special specification regarding the waste disposal must be made.
This specification should be given to the regulatory authority of the plant, which gives it to other relevant authorities and grants permission.
The specification describes the cleaning process, treatment of the waste chemicals and gives the benchmarks to be achieved on the water phase and the sludge phase. It also specifies where water and waste will be discharged and/or deposited.
Each specification is unique, since the conditions vary from place to place and the requirements on both cleaning results and waste disposal continuously becomes more strict.
