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
TenCate Geotube technology dewaters primary, secondary and overflow sludge from the sewage treatment plants’ digesters and lagoons. This municipal dewatering solution is used in water and wastewater treatment applications including lagoons, tanks, and digester cleanouts. The containers can provide dewatering and containment in one operation, with 85% to 90% reduction of BOD in the effluent. Most of the time, the dewatered effluent is clear and safe enough to be returned to the sewage treatment plants.
Use natural air currents for aerobic sewage treatment via venting pipes.
Alternatively, they can be solar powered using a very low energy 12 Volt fan.
The FILTERPOD requires no electricity for the treatment process. They finally allow modern, high quality sewage treatment for all regions of the world, even for off-grid locations.
Remote fly-in recreational fishing lodges often require effluent to be discharged directly into surface water. NOMADIC™’s membrane technology produces the highest quality effluent of any sewage treatment technology available today.
In sewage treatment plants, flow sensors are primarily installed for internal reasons. Ultrasonic flow meters are used to control the flow velocity in partially filled and fulfilled pressurized pipes, specific plant components, for leak detection or to control the use of additives. International regulations such as the EU-Directive for handling municipal waste water require flow metering for a continuous surveillance of waste water flow. Defective flow monitoring in sewage-treatment plants can therefore influence...
All described properties of Fe(0) nanoparticles can be even used for decomposition of pollutants contained in the waste water, mainly for treatment of industrial sewage and hutch water. The usage of nanoiron can represent a significant qualitative step in the classical technologies of water treatment including drinking water. The extremely reactive iron nanoparticles thus offer a possibility to solve long-lasting problems with a high content of uranium and arsenic in a variety of localities in the Central Europe....
AQQA is used in industrial wastewater treatment to: separate the sludge from the clear water in membrane bio reactors. constitute the final filtration of the effluent of standard sewage treatment plants (tertiary treatment). keep specialized bacteria in the system, that can biologically degrade organic matter. enable Zero Liquid Discharge: prefiltration for reverse osmosis systems.
Most nitrogenous materials in natural waters tend to be converted to nitrate, so all sources of combined nitrogen, particularly organic nitrogen and ammonia, should be considered as potential nitrate sources. Primary sources of organic nitrates include human sewage and livestock manure, especially from feedlots. The primary inorganic nitrates which may contaminate drinking water are potassium nitrate and ammonium nitrate both of which are widely used as fertilizers. According to the Toxics Release Inventory,...
