浅层砂过滤器 BRD Shallow sand filter

■产品概述
浅层介质过滤器是常州碧瑞达水处理科技有限公司的新型产品,产品近乎球形的外売和独特的内部设计可以确保过滤的水流平稳,多个罐体串联后使用,过滤效果更佳。在一些流量较大、过滤速度较快的场合可采用浅层砂过滤器,如工业、商业领域,如食品、纺织、治金、塑料、医药、建材、造纸、工业及商业建筑的暖通空调系统。

■ Product Overview
Shallow media filter is a new product of Changzhou birida Water Treatment Technology Co., Ltd. the product's nearly spherical outer shell and unique internal design can ensure the smooth flow of filtered water. Multiple tanks can be used in series, and the filtering effect is better. Shallow sand filter can be used in some occasions with large flow and fast filtering speed, such as industrial and commercial fields, such as HVAC system of food, textile, metallurgy, plastic, medicine, building materials, paper, industrial and commercial buildings.

 

■工作原理
主要通过滤料进行截污清洗,当滤料因截留过量的机械杂质而影响其正常工作,过滤器设置的反冲洗机构对滤料进行反洗。利用逆向进水,使过滤器内砂滤层松动,可使粘附于填料表面的截留物剥离并被反冲水流带走,有利于排除滤层中的沉渣、悬浮物等,并防止滤料板结,使其充分恢复截污能力,从而达到清洗的目的。

■ working principle
The filter material is mainly used for sewage interception and cleaning. When the filter material is affected by excessive mechanical impurities, the filter material is backwashed by the backwash mechanism. By using reverse water inflow, the sand filter layer in the filter can be loosened, which can make the intercepted substance adhering to the surface of the filler peel off and be taken away by the backwash water flow, which is conducive to the removal of sediment, suspended substance, etc. in the filter layer, and prevent the filter material from hardening, so as to fully restore the intercepting capacity, so as to achieve the purpose of cleaning.
