A Water Filter Removes Impurities From Water By Means Of A Fine Physical Barrier From A Chemical Process Or A Biological Process. Filters Can Be Used For Suspended Solids Removal, Removal Of Organics, Odour, Oil& Grease, Iron Etc By Selecting The Right Type Of Medium For Filtration. We Offer A Wide Range Of Water Filtration Systems That Provide You with Clean & Healthy Water To Use. Designed To Meet The Stringent Requirements Of Clients. These include the Entire Ranges Of Filter Are Available In Different MOC Like FRP, MS, MSRL, SS Etc. They Are Available In Fully Automatic, Remotely Operated, Manually Operated, Or With Multiport Valves.
Dual Media Filter / Sand Filter
Our Filters Work On The Principal Of Depth Filtration. The Principal Media In These Filters Is Quartz Grade Sand And Anthracite. Other Supporting Media Include Pebbles Of Various Sizes, Crushed Gravel, And Silex. The Major Advantage Of This Kind Of Filters Is That Anthracite Which Provides For Coarse Filtration Is Lighter Than Filtering Sand. Due To Which One Stage Of Coarse Filtration Takes Place On The Anthracite Bed And The Next Stage Takes Place On The Sand Bed. Thus, Depth Filtration Is Achieved. Since Both Media (Viz Sand And Anthracite) Are Employed The Dirt Loading Capacity Of These Filters Is Twice That Of Pressure Sand Filters. Hence These Type Of Filters Are More Capable And Give High Performance.
Activated Carbon Filter
The Principal Media In These Filters Is Activated Carbon. Other Supporting Media Include Pebbles Of Various Sizes, Crushed Gravel, And Silex. The Activated Carbon Is A Highly Porous Media. This Property Of Carbon Allows It To Adsorb The Free Chlorine In Raw Water. Also, Organic Matter Present In Colloidal Form, Oil & Grease Is Adsorbed In These Pores. Thus Odour Emanating From Raw Water On Account Of These Colloids Is Reduced. The Activated Carbon Present In The Standard Range Has An Iodine Value Of 450. This Carbon Is Also Available In Iodine Values Of 600, 900, And 1200.
Iron Removal Filter
The Principal Media In These Filters Is Manganese Dioxide. Other Supporting Media Include Pebbles Of Various Sizes, Crushed Gravel, And Silex. Manganese Dioxide Catalyses Precipitation Of Iron And Holds Back The Precipitated Matter On The Filter Bed. These Are Used To Remove Iron From Ground Waters.
Gravity Filters / AVGF
For Larger Flow Rates Where Pumping Is A Constraint, We Suggest Gravity Filter, Also Known As Rapid Sand Filters, Usually At The Outlet Of Pretreatment Plant. This Reduces Pumping Requirement And Can Be A Good Choice Where Space Availability Is Not A Constraint. AVGF Is A Boon For Places Which Are Remotely Located Where Operators Can Not Attend On a Regular Basis. Automatic Valve-Less Gravity Filter Comes With A Unique Feature Of Initiating Backwash Based On Pressure Drop And It Does Not Involve Any Automation Product Such As Auto-Valves, Controllers, PLCs Etc. It Operates On Gravity And Backwashes Purely On Delta-P Using Simple Hydraulic Principles. AVGFs Are Ideally Suited For Village Water Supply Schemes And Remote Locations.
