Water Process

Wastewater Process

Industry Expertise Flowrox has the valve or pumping solution to meet the challenge with in the Water and Wastewater Industry: Grit Slurry Sludge Primary Sludge Thickened Sludge Sludge Transfer Scum Primary Scum Thickened Scum Scum Transfer Sampling Systems Tank Dewatering/Flushing Sludge Dewatering Belt Filter Press Feed Centrifuge Feed Gravity Belt Feed Rotary Drum Thickener Feed Chemical Feed Systems Sodium Hypochlorite Sodium Bisulfite Methanol Lime Carbon Slurry Polymer Ferric Chloride Alum CSO / SSO Pumping Systems Return Flow Loops Hydrostatic Pressure Relief Flood Prevention Flowrox valves and pumps are designed and manufactured to withstand the most demanding process applications and extend the time between maintenance outages.

Water and Effluent Treatment Pumping Applications Lime treatment of effluent Metering flocculant Alum feed Metering of bromine chloride Chlorine monitors - sampling chlorine Metering sodium hypochlorite Metering fluoride Odor masking Sampling sewage, effluent and potable water Waste pit - pumping flocculant Waste treatment - re-circulation of leachate Waste water - dosing disinfectant Waste water aeration basin - meter liquid nutrients Water treatment plant – addition of carbon granules

CSO / SSO Backflow Prevention Larflex valves prevent the backflow of clean water into the overflow pipes of Sanitary Sewer Overflow (SSO) and Combined Sewer Overflow (CSO) When flap gates fail, backflow occurs and treatment plants are forced to treat the clean water because it has combined with sewage The persistent operational problems with flap gates, and resulting high maintenance costs, resulted in the US EPA issuing a grant to develop an "All Rubber Duckbill" to overcome problems with flap gates   Modified 15” Flanged For Combined Sewer Overflow

42” Flanged Installed for Flood Control Systems Flood control systems often incorporate multiple high volume / low head pumps in order to discharge large amounts of water rapidly Although the differential pressure is not great, these systems are often susceptible to backflow during high tides and storm surge Larflex valves are integrated into flood control systems due to their low headloss and reliable backflow performance These systems cannot take the risk of using rigid flap gate technology because of their history of not sealing, corrosion problems, and tendencies to freeze open or shut closed 42” Flanged Installed for Flood Protection

Levee Flood Protection Drainage pipes penetrate levee embankments to allow storm water runoff relief It is crucial to have the reliable backflow prevention capability of Larflex valve to prevent flooding of residential and commercial areas when the discharge pipe becomes submerged  Prevents flooding of residential and commercial areas Allows rapid discharge of runoff 24” Flanged Installed for Levee Flood Protection

Flowrox Pinch Valves Product features Technical features 100% tight Full bore Only the sleeve is in contact with the medium Linear control curve Centreline closing Technical features Sizes: of 25 to 1000mm Operating temperature: from -25°C to +160°C Operating pressure: from vacuum to 100 Bar Process benefits Excellent wear and corrosion resistance No jamming or clogging Self-cleaning Trouble-free operation Long service intervals The Larox valve utilizes two pinch bars which squeeze the sleeve from opposite sides closing the valve on the centerline Having two moving pinch bars which stretch the rubber sleeve creates a significant advantage compared to single pinch type pinch valves The stretching action of two pinch bars create less stress on the rubber sleeve and also insures a stretching and cleaning of the inner layer of the pinch valve sleeve. With each and ever operation the pinch valve sleeve is cleaned free of lime slurry scale build up Larox offers its SensoMate option which is a wear monitoring system built into the structure of the rubber sleeve Larox pinch valves are engineered to be the best available pinch valve in the industrial market today Larox pinch valves dwarf the pressure capabilities of traditional pinch valves. The Larox pinch valve is capable of handling pressures up to 1500 psig Centerline Pinching technology Self cleaning of scale build-up Sealed stem assembly Stainless steel internal moving components In the open position full flow with no obstructions and rubber lined for maximum life in the worlds most demanding slurries or pneumatically conveyed materials
