Stainless Steel Filters Tank Material：SS 304/316 Technology： Welding/Blasting/Polishing Sealing： Bolt cap O-ring Connection：Flange 4

Stainless Steel Filters Tank Working Status Weld voids, Acid mist, Acid water stains, Chemicals, Lack of Maintenance 5

PP Filters Replacement Process and Working Hours Take out the cap — 5 min Total 48 min Take out the filters and clean inside— 13 min Replace with the new filters— 5 min Fasten the bolts— 15 min Adjust and close the cap— 10 min 6

Working condition of PP filters ＊Outside-In ＊Remains are easy to fall into the vessel when replace the filter. 7

The Influence of Outside-In Filter Cartridges Sand / Carbon Prefilters Many times of replacement of filters RO system The carbon filter particle in RO membrane The particle of RO membrane Powered Carbons / Cements particle in RO membrane 8

Patented Max Flow Pleated Filter Housing Features ~ Material：FRP Process： Binding-Solid-Paint Spray Sealing：Auto lock cap Connection： PVC-Coupling Frame： Carbon Steel / Stainless Steel 9

Working Condition~ ＊Inside-Out ＊Remains can be removed when replace the filters. 10

LMF Filtration System -Multi Installations Feature~ Assemble: Vertical / Horizontal Capacity: can be expended by demand Application: Can be flexible designed with RO，UF Systems Install: on site 6 Filters Designed 4 Filters Designed 2 Filters Designed with RO system 12

Comparison Table Traditional Filtration System covers big area with equivalent water volume LMF Filtration System covers small area only 1/21/3 of the traditional one with equivalent water volume Time and labor consuming in Install Easy to install and replace the filter, 2 -4 times of LMF system The material of system can not meet corrosion resistance requirements The material of system can meet all kinds of corrosion resistance requirements The building cost of system is high The building cost of system is low only 1/4 -1/2 of the traditional one. The operation cycle of system is short The operation cycle of system is long is 2 -3 times of the traditional one. No expansion room for the water operation volume The water operation volume can be expanded to the demand 13
