Use CasesNeutralizing high-temperature boiler drainage in a small space
Customer's Needs and Problems
Alkaline drainage is generated from the boiler used at the factory.
Conventionally, this liquid would mix together with the miscellaneous drainage generated within the same factory, and this lowered the pH to within the discharge standards.
The boiler was updated to a large-capacity device, which increased the boiler drainage. Even if this drainage was diluted with the miscellaneous drainage, the pH still exceeded the standard value.
To adhere to the discharge standard, neutralization was required, which posed the following problems.
We heard the customer’s situation and considered a method that would not use a pit or large tank.
We came up with a method in which we installed a long distance of piping from the boiler’s drainage outlet to the neutralizing device, thereby cooling the drainage during transfer.
