With the increased use of storm water retention tanks, the need arises to routinely clean the tanks. Regular cleaning maintains combined sewer overflow (CSO) capacity and prevents septicity and odor problems associated with stagnant effluent. PWTech® Tipping Buckets provide a simple yet robust solution for flushing retention tanks.
Using Oxygen to Solve Waste Water Problems
Lack of oxygen can cause inadequate purification or even anaerobic decomposition, as well as offensive odors. Injecting oxygen into sludge beds &/or piping allows you to:
* Reduce nitrogen levels
* Meet peak O2 demands
* Have a back up to your aeration system
* Pre-purify waste water
* Control odors
* Deter corrosion damage
* Meet increased requirements regarding waste water purification
Force main systems are typically high sulfide odor generators due to septicity conditions related to full pipe flow and a greater anaerobic slime layer (biofilm) thickness. Primary factors that influence sulfide loading generation in a force main include sewage temperature, BOD, retention time, pipe size and flow. Gaseous hydrogen sulfide (H2S) release at the force main discharge is usually the main concern related to odor and corrosion control needs; however, corrosion problems within the pipe can be of a...
In the treatment of sanitary sewage, bio-solids are separated from the liquid. These bio-solids are concentrated and dewatered using filter presses, centrifuges, or other devices. Hydrogen sulfide and mercaptans are released during the dewatering operation. Carus permanganates react quickly and produce immediate results for hydrogen sulfide removal in order to provide a safe, odor free environment and minimize corrosion due to sulfides.
Sulfide Odor Control
Sulfide is found throughout the environment as a result of both natural and industrial processes. Most sulfide found in nature was produced biologically (under anaerobic conditions) and occurs as free hydrogen sulfide (H2S) - characterized by its rotten egg odor. We are most likely to encounter biogenic H2S in sour groundwaters, swamps and marshes, natural gas deposits, and sewage collection/treatment systems. Manmade sources of H2S typically occur as a result of natural materials containing...
