The presence of dissolved solids presents both physical and financial challenges for aeration diffusers in any wastewater treatment operation and can be particularly problematic in high-concentration industrial and food-processing applications. Here are some warning signs, insights, and solutions for coping with conditions that can lead to excessive dissolved solids accumulation.
Wastewater from dairy applications has high amounts of calcium and phosphorus. This characteristic may cause scaling on the media of a Moving Bed Biofilm Reactor and may cause poor COD removal. Veolia was able to retrofit the client’s existing MBBR with the newly designed Z-MBBR media by AnoxKaldnes, which improved the operation of the entire wastewater system.
The Escalon Industrial Waste Water Treatment Facility’s service area is seasonal and centered on tomato and pickle processing. The production season (roughly mid-July through mid-October) sees high hydraulic- and BOD loads that strain the facility’s capacity. During the high season highly variable BOD load depletes DO and causes permit violations and odor complaints. Praxair installed 4 X 15 HP Medium Velocity Oxygenation (MVO™ oxygenation system), with the ability to deliver up to 6 TPD of oxygen to supplement the existing aeration capacity at the facility.
The hardest aspects of comparing efficiencies among submerged aeration technologies are the many variables in capital expense (CAPEX), operating expense (OPEX), and complexity of wastewater makeup. Instead, consider comparing the physics of different aeration technologies and the relative costs associated with them. Here are five major categories for evaluating industrial wastewater aeration efficiency.
The use of low salinity water in Enhanced Oil Recovery processes has been a recent topic of discussion. The potential to increase recovery rates by altering the reservoir characteristic from an oil-wet to a water-wet state, along with potential cost savings, has garnered attention in recent years.
Are your current pressure-boosting pumps the best design for your operating conditions? Are they maximizing value from your operating budget with peak efficiency? How can you know for sure, and what can you do if they are not? Here are some guidelines for evaluating performance efficiency in pressure-boosting applications and for choosing the best pump configurations for new or existing applications.
Ken’s Foods is a privately held food manufacturing company located in Marlborough, Massachusetts, USA. For 60 years, Ken’s Foods has been making an extensive line of salad dressings, sauces, and marinades.
In the sugar and bioethanol industries, robustness and reliability of the equipment are of paramount importance. The XFP pumps were taken into operation in 2013 and have been running continuously since then, without any interruption or specific maintenance.
A California winery was having odor problems from its wastewater evaporation lagoons. The wash and wastewater from this facility contain large amounts of organic matter. The wastewater is collected and pumped to two main lagoons for evaporation, percolation, and sprinkler irrigation.
A balanced wastewater process is a beautiful thing — plenty of biochemical oxygen demand (BOD), plenty of O2, and all those hungry little microbes are fat and happy. But what can be done when dissolved oxygen (DO) takes a nosedive and there’s not enough O2 to satisfy industrial and food processing BOD? Here are some preparations to consider before wastewater treatment goes completely out of whack.
Precise water quality is critical for municipal water treatment operations, but many industrial applications have even more rigorous requirements, regulations, and guidelines to follow. The energy, pharmaceutical, food processing, and other industrial fields require exact water quality in order to function efficiently.
See how Xylem partnered with WateReuse Colorado and Invintions Winery to create wine using purified recycled water.
At Fluence, we have more than 30 years of experience in the design, construction, and operation of waste-to-energy plants for a wide range of industrial and municipal clients. Our proprietary anaerobic treatment technologies process wastewater and sludge to produce biogas, which can be used to produce electricity and thermal energy, or which can be purified to produce biomethane for injection into the grid.
L'eau Claire upflow filters offer an alternative to conventional water clarifiers for removing suspended solids and colloidal material such as silica. Despite the influent loading, this cost-effective filtration process removes 98% of particulates ≥2 microns without the use of clarifiers, flocculation, sedimentation, dry chemical addition or mixers. Watch the video to see how it works.
A hospital had been pumping their wastewater with a submersible pump for years. But after seeing the benefits of the S&L Above Grade Wet Well Mounted Pump Station, they quickly saw the benefits - easier and safer maintenance, higher efficiency, long pump life, and more. Hear from the operator himself to learn why the hospital now prefers S&L's EVERLAST™ Wet Well Mounted Pump Station.
Many food processing facilities operating today were designed and built to accommodate consumer habits of a bygone era. As those commercial markets have evolved, and industry has adapted to the changes, the wastewater plants at those sites are no longer capable of processing the waste generated during production.
This article disucsses two trends turning the flowmeter industry on its ear: advances in flowmeter diagnostics and the adoption of smartphone-like technology to improve access and communications.
Every year, World Water Week, a conference organized by the Stockholm International Water Institute(SIWI), brings together experts from around the world to discuss global water issues. This year’s event focused on Water, Ecosystems and Human Development, with discussions concentrating on how business, NGOs and government agencies are collaborating to address water-related challenges.
Three thousand litres of water — that is the amount needed to produce the food each British person eats every day. This is according to a new study into the “water footprint” of diets in Western Europe, conducted by the European Commission and published in Nature Sustainability.
Industrial companies need reliable water treatment technology, since failure of a water system may result in downtime for production, with significant financial impacts. Ultraviolet (UV) technology is used for water treatment in various industries such as microelectronics, food & beverage, pharmaceuticals, and many other industry segments.
The Greater Lawrence Sanitary District (GLSD) in North Andover, MA, was one of 28 organizations nationwide to be honored for an innovative water or wastewater project in the most recent PISCES Recognition Program sponsored by the Clean Water State Revolving Fund (CWSRF). PISCES stands for Performance and Innovation in the SRF Creating Environmental Success.
By harvesting heating, ventilation, and air conditioning (HVAC) condensate, industrial operations can take advantage of a cool, convenient source of clean water.
As focus on resource recovery intensifies, food and beverage operations are under a particularly large microscope. An anaerobic digester designed for the food and beverage industry can create value out of the space’s unique wastewater.
If you’ve ever looked into the ice cream freezers at your local grocery store you can imagine all the different ingredients you’d find at the ice cream factory: cream, sugar, chocolate, fruit, nuts, milk, syrups, and so on.
Anaerobic digestion is a practical and efficient technology to utilize considerable amounts of organic waste from intensive animal production and food processing and wastage during distribution/consumption, municipal waste, etc. to produce methane gas for electricity generation, local/process heating, and direct injection into the gas supply network.
Wastewater treatment operations are beginning to embrace the power of automation. How can it help? And how is it implemented?
Electricity is a major cost for industry operations, and the cost of meeting environmental regulations is right up there as well. At the same time, industries are compelled to improve sustainability and lower their carbon footprints.
Technologies which could transform the shape of the water industry of the future will be on show at the fifth BlueTech Forum, to be held in San Francisco.
Wineries and vineyards face some added environmental and economic challenges to properly treat and dispose of wastewater. Proper treatment and disposal can be costly and there are very strict regulations that must be followed.
