Odour emissions form a serious problem for many people that live near or work in places which produce odours. These places can be factories, wastewater treatment plants, farms like pig and poultry breeders, solid waste disposal facilities and landfills. As some odourous compounds can be harmful for the health of humans other are simply unpleasant and can cause health problems when exposed to on a continuous basis. In either case something needs to be done about it.
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.
Filamentous sludge is a common problem at activated sludge plants. With ozonation of the return sludge flow it is possible to reduced the amount of filamentous bacteria in the sludge and significantly increased the settling properties of the sludge.This in turn means better performance of the activated sludge process. When a bioreactor is connected to the sludge line the removal of the damaging filamentous bacteria means higher quality sludge in the bioreactor, which leads to higher biogas production.
Tracking the tiniest cracks – with H2O wastewater treatment. Heavy use, material fatigue and material faults can cause tiny cracks in plastic and metal parts. These are so small that they are invisible to the naked eye. But they can still be relevant to safety, e.g. on the wings of passenger jets. That’s why these parts are regularly checked for micro cracks. One way of doing this is the dye penetration process, where the part to be checked is first thoroughly cleaned. Applying a special dye and using...
The most significant problem in the dairy sector is the high concentration of fats and oils involved. This kind of water involves various pH values and peaks in temperature. These characters make a complex treatment system necessary.
B & V Effluent services have been successfully helping brewers and distillers throughout the UK with the management of their effluent systems for nearly 30 years. As a result the B & V Effluent Team holds a vast amount of specialist knowledge in regards to the problems faced within the beverage industry including the management & reduction of pollutants in general to meet discharge consents.
Proper waste treatment and free-flowing plumbing lines are critically tied to one another. Of the many products marketed which claim to aid plumbing problems, MICROCAT® products are unique. They offer a combination of micro organisms, enzymes (biochemical catalysts) and other ingredients which act together naturally to soften, loosen, remove and break down greases, fats and oils in plumbing lines, sewer systems, pump stations and treatment plants, thus keeping them clean and odour free. Developed through the...
Wastewater Deodorization: The formation of hydrogen sulfide often poses a problem for municipal wastewater treatment. Chlorine dioxide, a powerful oxidant, can be effectively used to control noxious, irritating, or pungent odors from many operations. Moreover, its unique selective properties permit more efficient application at a lower dosage and cost than chorine, hypochlorite, permanganate peroxide or ozone.
Membrane units, in our days are widely used in the water pre-treatment preparation and are becoming one of the most important technologies in the production of high pure water. Nevertheless they often face problems with scaling and fouling and are therefore limited by frequent maintenance, downtime and high costs. Our treatment programs are specifically designed for membrane units like reverse osmosis, ultra- and nanofiltration and enable to remove or preventive control scaling and fouling. Our main target is to...
Industrial and municipal waste contaminated with fat – a frequent problem for companies maintaining wastewater network infrastructure and municipal wastewater treatment facilities. We recommend the use of GREASOLUX fat dissolvent cartridges to avoid the problems of pipeline chocking, equipment damage, offensive odors, formation of filamentous bacteria, poor wastewater treatment results, poor sedimental properties of activated sludge. GREASOLUX – is a cartridge that slowly dissolves in water, enriched...
Odor from industries is a growing problem as cities are expanding closer to industrial areas. The production at food processing industries, fish factories, biodiesel plants and the like can create odors that might be a nuisance to the surrounding area. Odor control systems has thus become important to industries located closed to urban areas.
As one of the world`s most precious natural resources, the reuse of water is becoming increasingly important. MIOX is both the most cost-effective solution and the preferred technology for disinfection and oxidation of wastewater for reuse or reintroduction into the environment. MIOX`s hypochlorite generators offer a safer, technologically superior solution to wastewater treatment, virtually eliminating many of the negative problems associated with traditional chlorine disinfection. Safer, economical and significan...
Controlling algae, cyanobacteria and fouling efficiently with ultrasound to reduce taste and odor problems in the treatment plant. Prevent taste and odor problems. Control fouling in sand filters and clarifiers. Improve coagulation and flocculation processes.
Ballast Water Solutions. Ship ballasts often carry aquatic organisms that can cause a significant problem when transported from one body of water to another. In fact, the invasion of non-native species via ballast water has been described by maritime and environmental authorities as `one of the greatest threats to the world`s waterways.`
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
Cyanides are used in a number of chemical synthesis and metallurgical processes (as simple salts or cyanide complexes). As a class, cyanides are highly toxic and must be destroyed or removed from wastewaters prior to discharge. The most common method for treating free or simple cyanide is alkaline chlorination. However, chlorination of cyanide results in highly toxic intermediates (e.g., cyanogen chloride) and, if organic material is present, chlorinated VOC’s. These compounds, together with the residual chlorine,...
They have a high content value for organic material, solids, oils and grease, with the added presence of nitrogen, produced particularly in the cleaning, descaling, peeling and bone extraction process. To avoid the problem of salinity, several components can be made using ASI 314.
In wastewater treatment, the aeration system is often the largest energy consumer. It seems the age-old answer for every problem was to increase horsepower and add more aeration. When you analyze aeration, only 20% to 50% of the energy consumed is needed for production of dissolved oxygen (DO) for processing BOD and nitrifying bacteria. The remaining energy is used just for the mixing effect.
Wastewater treatment plants can on occasion experience problems with settling of the biological sludge in the secondary clarifier. Often this problem is caused by the abundant presence of filamentous microorganisms.
