Eliminating Sludge Islands In Your Wastewater Lagoon By Jim Dartez, RELIANT Water Technologies
Old municipal and industrial wastewater lagoons have the tendency to build islands of sludge at various locations around the lagoon. It is most common for older lagoons to build such islands wherever wastewater enters the lagoons.
Optimizing Air Flows To Aeration Basins By Sierra Instruments, Inc.
As a result of clean energy mandates and the rising cost of energy, wastewater treatment facilities around the country are retrofitting their instrumentation to run highly efficient, cost-effective, clean facilities. To reduce emissions and produce clean energy, solid wastes are often digested in large digester tanks to reduce the volume of waste (sludge) and produce more biogas, which is then used as fuel in the cogeneration process.
Using Membrane Contactors To Remove Dissolved Gases From Feedwater By Membrana
When engineers at the Kori nuclear power plant in South Korea found that dissolved nitrogen in reactor feed water led to an increased production of carbon 14, a long-term environmental contaminant, they sought a way to minimize its production. Membrane contactors were installed to simultaneously remove both dissolved nitrogen and oxygen from the water.
The MIOX Blackwater Trailer is a mobile, chemical-free, on-site water treatment system for high-volume disinfection. Capable of dosing between 100 to 150 mg/l and higher, this mixed oxidant solution (MOS) system achieves complete kill of both sulfate-reducing bacteria (SRB) and acid-producing bacteria (APB). MIOX technology operates with salt, water, and electricity, so there are virtually no health, safety, spill, or environmental concerns.
Designed via feedback from actual field users, the MC4-150 dry calcium hypochlorite feeding system prepares and automatically delivers a consistently accurate dose of liquid-available chlorine for disinfection applications.
