![Repair Of Major Damage To High Density Polyethylene Wastewater Pipeline]( "Repair Of Major Damage To High Density Polyethylene Wastewater Pipeline")
Repair Of Major Damage To High Density Polyethylene Wastewater PipelineLeprino Foods, the world's largest mozzarella cheese producer, operates two plants that share one wastewater pipeline – a 16” SDR11 High Density Polyethylene Pipeline (operating at approximately 160 PSI). During dirt work an “auger” hit the wastewater pipeline and drilled an 8” diameter hole in the line. Leprino needed immediate access to a repair fitting for this line.

Disc Aerators Replace Brush Aerators, Increasing Capacity And Performance
To comply with new EPA rules and handle additional flow, the City of St. Charles Missouri WWTP required a capacity increase, and the landlocked plant needed a solution that would fit within its existing footprint. Brush aerators and boat clarifiers were replaced with 12 VLR-mounted disc aerators to fulfill the oxygen requirement while allowing for the treatment of higher organic loading. The solution provided increased nutrient-removal capacity and improved efficiency without increasing tank volume.

Why Measuring Hydrogen Sulfide In Wastewater MattersHydrogen sulfide (H2S) gas in wastewater environments is a familiar concern. But waiting until its odor is detected can be too late to exert as much control over it as desired. Fortunately, a new ability to monitor H2S concentrations — in the liquid wastewater stream, in real time — is advantageous for wastewater professionals in terms of safety, cost, and consumer complaints. Here are four ways to capitalize on that capability.

WASTEWATER PRODUCTS
De Nora Water Technologies developed the direct gas-pressure chlorinator for applications where electricity, used to operate a booster pump, and water pressure, required for ejector vacuum operation, are unavailable.
The 3-Way Valve is available in 4”, 6” and 8” sizes and is available as a stand-alone valve or as part of a Vaughan submersible or vertical wet-well Chopper Pump. The valve is a non-plug design using a rotatable CD-4MCu valve disc to allow discharge out of either of the top ports.
The OPTIMASS 1400 is a cost-effective twin straight tube Coriolis mass flowmeter for a wide range of standard applications with gases and liquids (up to 170,000 kg/h or 6,235 lb/min). The meter features Entrained Gas Management (EGMTM) for liquid applications, providing reliable readings even in the event of gas entrainment of up to 100%. In this way, the Coriolis meter enables continuous and uninterrupted measurement of volume flow and mass, density and temperature – even at difficult process conditions with 2-phase flow.
