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...
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,...
MICROCAT microbial formulations from Bioscience, Inc., are blends of specialized, naturally occurring microbes and other ingredients that work together to solve the most common, damaging problems inherent to municipal wastewater plants. By augmenting existing microbial populations, MICROCAT products naturally aid in stabilizing municipal sewage treatment and collection systems, enhancing their ability to break down difficult-to-degrade wastes and handle highly variable waste treatment conditions.
Dewatering and Thickening of Municipal Sewage Sludge using the Decanter. Flottweg has more than 50 years of experience in dewatering and thickening sewage slurry. We know the special requirements of sewage treatment plants and the water industry. As a result, we have developed a special decanter series especially for sewage treatment plants: the Flottweg C series.
The filtration of the grind sewage takes place in an arrangement of procedure. If necessary, an individual designed Zyklon-container or a "Grobfilter" is associated in combination with in turn connected Zyklonfilters. Policefilter and special flow movements support the process. The size and the version of the plant depends on the customer`s demand and could be completed just as they like.
About a decade ago it became known that pharmaceutical residue in river water had caused fish to change sex. Recent studies show that pharmaceutical residue alters behavior of perch. Many studies have concluded that waste waster contains micro pollutants like pharmaceutical residue. This water is released from our waste water treatment plants into the environment without proper treatment. Many countries in Europe are now taking political action to reduce the effects of the pharmaceutical residue. In Switzerland,...
Aeration Process Introduction: Waste Water Treatment removes impurities and contaminants from a com¬munity`s sewage utilizing a number of different processes and a variety of equipment. One of the processes is the use of surface aerated basins that use aerobic micro-organisms to remove 80 to 90% of organic matter in waste water. Oxygen concentration in the water basins is a critical factor to promote the optimum micro-organism growth rate needed to treat the water in the shortest amount of time. As a result,...
Industry and municipal waste-water (sewage) treatment plants have had to respond to environmental legislation such as the Urban Waste Water Directive, IPC, IPPC and now the EPR (Environmental Permitting Regulations). As successive legislation becomes more stringent, discharge consents have been progressively tightened, and the need for self-regulation has become more important. As a consequence, on-line instrumentation has been installed throughout waste-water industry to continuously to provide final effluent...
