FRP Tank and Vessel In Water Treatment

The Working Principle of FRP Tanks

1. Purification principle

• Raw water enters the filter storage tank through the inlet pipe and is uniformly distributed throughout the filter media layer through the distributor.
• Water moves downward with the filter media layer , with put on hold solids, colloids, and other impurities being maintained and adsorbed by the filter media. Clean water is collected by the collection agency and released with the outlet pipe.”.
• When the filter media comes to be saturated with adsorbed contaminations, backwashing is done. Backwash water enters from the bottom, causing the filter media layer to broaden and loosen up, and pollutants are released with the drainpipe pipeline together with the backwash water, recovering the filter media’s filtration capacity.

2. Structural principle

• Storage tank body:  FRP wound building , consisting of an inner lining layer (corrosion-resistant), architectural layer (load-bearing), and external protective layer (UV-resistant), with the ability of enduring water stress effects and water top quality corrosion.
• Water circulation system: The leading makes use of a bell-mouth or perforated plate distributor to ensure uniform water circulation distribution and stop local filter media overload.
• Water collection system: The lower utilizes a dome-shaped perforated plate or branch pipe-type water collector to make sure consistent water discharge without filter media loss.
• Assistance layer: Located listed below the filter media, it utilizes river stones or quartz sand to support the filter media and make certain uniform water circulation.

3. Detailed Functional Refine

• Filtration stage: Inlet valve open → electrical outlet valve open → drainpipe shutoff shut; water moves with the filter media for purification, continually generating water.
• Backwashing phase: Inlet shutoff closed → backwash inlet shutoff open → drain valve open; water streams in the opposite instructions to backwash the filter media, lasting 5– 10 mins.
• Forward Flushing Stage: Close the backwash inlet shutoff → Open the inlet shutoff → Open up the drain valve, forward flush residual contaminations, lasting 2-3 minutes.
• Operational Control: Automatic control systems set off flushing based upon time or stress differential; handbook control systems call for manual valve operation.

What are the types of FRP tank ?

• Quartz sand filter tank: Eliminates put on hold solids, silt, rust, and other particulate contaminations from water, used for municipal water pretreatment and swimming pool water filtration.
• Activated carbon filter tank: Adsorbs organic compounds, smells, residual chlorine, and various other impurities from water, made use of for drinking water advanced therapy and post-treatment of wastewater for decolorization and deodorization.
• Manganese sand filter tank: Gets rid of iron and manganese ions from water, made use of for groundwater therapy and well water purification.
• Multi-media filter tank: Split with quartz sand, anthracite, turned on carbon, etc, for multi-stage filtering, utilized for industrial water pretreatment.

Setup and Maintenance Standards

• Installation Demands : The equipment needs to be set up indoors or in a sheltered outside location, preventing direct sunshine and rainfall; the installment website have to be degree, with ground load-bearing capacity conference devices requirements; inlet and electrical outlet pipes must have reserved valve and stress scale user interfaces for upkeep comfort.
• Installation Steps : First, setting the devices, attach the inlet and outlet pipes, water drainage pipelines, and various other piping, after that mount the electrical control system. After linking the power supply, perform commissioning and set parameters such as backwashing cycles and operational setups.
• Daily Upkeep : Regularly inspect the stress differential of each filter. When the pressure differential goes beyond the established value, execute backwashing; based on usage problems, on a regular basis change filter media such as quartz sand and turned on carbon; Keep the surrounding setting clean to prevent dust from going into the equipment.

How is the control method for FRP pressure tank?

• Manually controlled filter container: Runs purification and backwashing via hands-on valves, ideal for small systems and recurring procedure scenarios.
• Automatically controlled filter tank: Outfitted with a multi-port valve or PLC control system, automatically completes purification, backwashing, and rinsing processes, appropriate for massive systems and continuous procedure circumstances.
