The small size of steel valveless filter series products is square and flat top cover, while the large size is round and arched top cover. It has good health protection conditions and can be set in the open air. Compared with reinforced concrete filter, it has small self weight and can use asphalt sand flexible foundation.

鋼制無閥過濾器系很適用在地表水凈化（如大中小型景觀水、人工河湖、噴泉瀑布等循環(huán)水的過濾）；地下水除鐵除猛；旁流水旁流過濾；生產(chǎn)廢水去除懸浮雜質(zhì)；有機(jī)污水經(jīng)生化處理、二次沉淀池處理之后的后續(xù)過濾，以及室內(nèi)游泳池水的過濾。

The steel valveless filter system is very suitable for surface water purification (such as large and medium-sized landscape water, artificial rivers and lakes, fountains and waterfalls, etc.); Removal of iron and iron from groundwater; By pass water by pass filtration; Removal of suspended impurities from production wastewater; After biochemical treatment and secondary sedimentation tank treatment, the organic wastewater is filtered, and the indoor swimming pool water is filtered.
