Supply & Install Range
-Filter Body Includes All Inside Parts.
-Filter Outer Parts Like Siphon& Drainage Water Tubes as well as Tube Supports
-The Connecting Pipeline, Valves & Supports Among Same Group Filter Tanks.
-Steel Filter Drain Clean Valves, Short Pipes And Elbows.
Media & Support Media Arrangement Method
- Clean All Impurities After Mounting The Filter, Then Mark Each Proof Height Line Of Each Media And Support Media In Filter Inner Wall, Double Check Each Grain Dn Range To Fill Them From Large To Small For Real Distribution.
- Carry On Support Media Arrangement From Bottom Average-Thickness Support Media (Material) To Upper In Line With All Formal Marked Line.
- After Finishing Support Media Arrangement, Then Distribute Filter Media Same As Before Carefully To Make Sure Its Proportionate Arrangement In Line With Marked Line By Adjusting Them With Blade.
Mounting Description
- When Put Filter Into Site Position, Must Check Level Again To Make It Mounted Smooth And Stable, It Will Be Welded Into The Bottom Steel Plates And Fixed.
- Water Tank Bolted With Filter Roof Beam Support To Make Two Weirs Into Same Level Height Thus To Safeguard The Water Distribution Averagely.
- Connecting Flange And Screw With Siphon Tube System Must No Air Leakage And Strictly Control The Height Of Siphon And Auxiliary Tube Proof Position.
- Besides Special Inside Corrosion-Proof Treatment, The Outside Surface Also Need Do Color Stipulated Coating.
Operation Description
- First Running, Use Rubber Tube To Inject Clean Water Into Water Tank To Make Water
Going Through Filter From Bottom To Upper Via Connecting Tube To Drain Out The Air In Filter.
- First Back washing , Adjust The Washing Intensity Into 1/4 Of The Siphon Reduce Tube DN Position Via Intensity Adjusting Device , After That , Increase The Opening Degree Gradually Till Regulated Value.
- During Operation, Must Check If Its Filter Media In Level Position Or Being Polluted Esp. When As By Pass Filtering Circulated Cooling Water Whose Filter Media Is Easy To Be Polluted By Algae, If Found , Must Remove The Polluted Media Layer Around 100mm Thickness And Then Change It As New Filter Media.
