XY-311 defoamer can be used in stock solution(undiluted) or diluted with thickened water for use.
It is suggested that use a suitable device and/or tool, add this product into the place where it can disperse easily.
In pulp washing section, use a metering pump for continuous adding through the filling point.
Rate of flow: 5-15L per hour, use a metering pump
10-100 ppm for waste water treatment use
The optimal adding point, adding amount, adding method and dilution ratio should be based on a series of lab and field test result. Proper dosage level of this defoamer is sufficient for inhibiting and breaking the foam effectively, don't use it excessively.
