What is the wastewater discharge volume using soft water? What is the wastewater discharge volume with a conductivity of 0.1 us?

When the steam pressure is greater than 2.5 MPa, the blowdown rate should not exceed 5% ； 3. When the steam generated by the boiler is used by heat-driven steam turbine generators and chemically softened water is used as make-up water, the blowdown rate should not exceed 5% ； When chemically treated demineralized water is used as make-up water, the blowdown rate should not exceed 2%.
The waste discharge rate is generally 0.5-1% of the boiler’s evaporation volume
