FRP Wastewater Treatment Tank

Yingnai FRP Wastewater Treatment Tanks are built for industrial wastewater equalization, neutralization, precipitation and chemical treatment processes. Corrosion-resistant resin systems can be selected for acidic, alkaline or saline wastewater. Customized chambers, mixers, baffles, dosing ports and instrumentation connections allow the tank to integrate directly with different wastewater treatment technologies and operating layouts.

Typical Diameter RangeD 1000–4500 mmOther dimensions can be engineered
Main Sizing DimensionTank length LSee the three sizing-matrix sheets
Installation OrientationHorizontal, aboveground; buried service only by specific designInstallation method depends on site and transport limits
Fabrication MethodFilament-wound shell with molded heads and reinforced saddle zonesSelected according to diameter, capacity and access
Structural ConfigurationInner corrosion barrier, structural laminate, outer protective layer and saddle reinforcementLaminate schedule is project-specific
Resin OptionsSame resin options, selected for the stored mediumFinal resin must be checked against medium, concentration and temperature
ReinforcementSurface veil, mat, woven roving and continuous winding rovingGlass type and content follow the laminate design
Design PressureAtmospheric as standardPressure or vacuum service requires a separate verified design
Operating TemperatureDesigned according to resin system, medium and actual service conditionsDo not publish a single universal temperature limit without resin verification
Operating MediumWater, wastewater, chemical liquids and selected industrial mediaChemical compatibility review is required
Design Specific GravityProject-specific; based on stored-liquid density and transport/support loadsCustomer should provide normal and maximum density
Corrosion BarrierResin-rich inner surface with chemical-resistant veil and laminateBarrier thickness and resin are selected for the medium
External ProtectionUV-resistant resin-rich layer, gel coat or project coatingColour and protection system can be customized
Tank Bottom / SupportsFRP or steel saddles with anchor arrangementFoundation reactions must be confirmed by final design
Inlet and OutletDiameter, location, flange standard and reinforcement customizedPiping loads should not be transferred directly to the shell
ManholeTop or side manhole customizedAccess and maintenance requirements govern arrangement
Vent / OverflowVent and overflow connections as requiredSizing follows filling, emptying and process conditions
Optional AccessoriesSaddles, hold-down straps, lifting lugs, level gauge, baffles and insulationAccessory loads must be included in structural design
Inspection and TestingSame, including saddle alignment and support inspectionTest scope follows contract and applicable code
Applicable ReferencesProject specification and applicable RTP/FRP laminate standardsReference does not imply certification unless contractually stated
Installation MethodSaddle-mounted installation; buried installation only with engineered backfill and external-load designInstallation manual and lifting plan should be project-specific
Application FieldsIndustrial liquid storage, wastewater, chemical service, transport-limited sites and underground applications by designActual suitability depends on medium and hygiene requirements
CustomizationCapacity, diameter, length, resin, saddles, nozzle layout and buried/aboveground arrangementManufacture according to approved drawings
Required Inquiry DataMedium, concentration, temperature, density, capacity, support/burial condition and nozzle listThese inputs are required before final quotation and design
