Lamination directly influences the laminated filter performance and service life. Based on the lamination of two different types of port layout, the law of its head loss was studied under different flow rate of clear water conditions. The results showed that under the condition of clear water, with the increase of flow rate, the head loss and flow of the two laminations presents a power function relationship, and the added value of the head loss of two kinds of lamination experienced a substantial increase, further analysis of the head loss between the two kinds of laminated difference, the head loss of the two kinds of laminated both present linear function relation with the difference between the flow. The test conclusionis: through the experiment, the head loss of the composite flow laminated filter is superior then the traditional flow path, but also need follow-up tests verify the anti-clogging performance; in addition, this paper for the domestic water market provides a new product.
