Tideflex Mixing System (TMS) for Water Reservoirs

• Separates  Inlet and Outlet.
• Eliminates short-circuiting and achieves complete mixing.
• Mitigates ice formation.

The Tideflex Mixing System (TMS) has been extensively CFD and scale modeled and field validated to significantly improve storage tank water quality by eliminating short-circuiting and achieve complete mixing.  The TMS is completely passive and does not require an outside energy source.  It operates on the existing differential pressure when the tank levels are fluctuated.  For every tank, Tideflex engineers select the optimum TMS configuration and run Manifold Hydraulics and Mixing Analysis Models.  The Mixing Analysis links the TMS configuration efficiency and Manifold Hydraulics to provide data on the amount of tank turnover required to achieve complete mixing once the TMS is installed.

Overflow Pipe Protection

• Tideflex valves will not rust or corrode open or shut.
• Tideflex valves completely drain, no standing water.
• Prevents cold drafts and airbourne pathogens from entering tank.

Mesh screens and flap gates have typically been installed on the end of overflow pipes.  Screens rust, become dislodged, and do not prevent cold air and airbourne pathogens from entering the tank.  Flap gates can corrode open or shut and require maintenance.  Tideflex valves on overflow pipes provides a maintenance free solution to overflow pipe protection.

Overflow Security Valve (OSV)

• Increase tank security.
• Reduce potential for terrorist attack.

While conducting vulnerability assessments, many water utilities identified tank overflow pipes as a source for potential terrorist attack on the public water supply.  Red Valve Company developed the OSV to increase the security of water tanks.  The Tideflex duckbill check valve is hidden within the OSV assembly and cannot be tampered with once the assembly is installed in the overflow piping.

Reclaimed / Reuse Water Tank Mixing Systems

• Reduce solids with improved mixing.
• Reduce biological regrowth, algae growth and odor problems.
• Maintain disinfectant residual.

The Tideflex Mixing System (TMS) reduces water quality problems, associated to the loss of disinfectant residual and biological regrowth, within reclaimed water storage tanks by eliminating short-circuiting and achieving complete mixing.  When tanks are not completely mixed, the water quality (pH, residual, DO, etc.) can vary through the depth and this variance can promote corrosion and biofild problems.  With complete mixing, water quality will not vary through the depth.  The TMS is passive, does not require maintenance, and mixes the tank with the differential pressure when tank levels are fluctuated.

Pump Check Valves

• Non-mechanical.
• No slam.
• High back-pressure rating.

Waterflex check valves are used in clean water pumping applications to eliminate slam and maintenance issues common to other styles of check valves.  The Waterflex is passive, has no mechanical parts and operates soley on differential pressure.  The custom engineered membrane is fabric-reinforced and vulcanized with a preset to ensure long term performance and sealing characterisitcs.

Filter Check Valves

• Non-mechanical.
• No slam.

Water treatment filters incorporate Tideflex duckbill check valves on the filter to waste and backwash pipes to prevent backflow.  Tideflex valves are passive, non-mechanical and operate solely on differential pressure.

Alum Sludge Mixing Systems

• Mixing and odor removal of alum sludge.
• Coarse bubble diffusers with duckbill check valve design.

Water treatment processes utilizing alum as a conditioner have to manage this difficult sludge prior to disposal.  This alum sludge contains organic materials which can produce odors through decay during stroage periods.  This sludge is also dificult to manage due to it's consistency and adhesion characterisitics.  The Tideflex coarse bubble aeration system is ideal for providing mixing and aerobic conditions without generating maintenance problems with the equipment.  The Tideflex duckbill check valve technology which is incorporated into the diffuser units provides backflow prevention of the sludge into the distribution system allowing for continual operation without downtime for maintenance.
