GEM + MBR - Catering Water Recycle - Case Study
Introduction An in-flight catering and commissary terminal (SATS) was in need for a more advanced wastewater treatment system, as their current wastewater treatment solution was inefficient and did not meet discharge requirements. CWT and its partners developed a solution which allowed ATS to not only treat their water to reduce discharge costs, but also allowed water re-use as well. Challenge ...

Investment and operating costs of municipal wastewater treatment plants in China
The municipal wastewater treatment will continue to be intensified in China due to the economic development and the poor water quality. Within four years, the number of wastewater treatment plants has doubled. Before 2000, mostly plants without nitrogen and phosphorous removal were built. Since Chinese laws require strict effluent qualities, many plants were built with ...

What is the textile effluent treatment?
Water is the most wonderful gift of nature. Water is most useful and abundant compound in the earth. Water is not only essential for human lives, animals, plant lives but also has a unique importance in industries. The textile industry uses water very intensively. Water is the main principle medium in the textile industry to apply dyes and various finishes. Thus the textile wastewater ...

Energy-efficient wastewater treatment via the air-based, hybrid membrane biofilm reactor (hybrid MfBR)
We used modeling to predict the energy and cost savings associated with the air-based, hybrid membrane-biofilm reactor (hybrid MfBR). This process is obtained by replacing fine-bubble diffusers in conventional activated sludge with air-supplying, hollow-fiber membrane modules. Evaluated processes included removal of chemical oxygen demand (COD), combined COD and total nitrogen (TN) removal, and ...

Compliance is King but at What Cost?
For years Plant Managers sole purpose has been to ensure that their plant remains within it’s set compliance ranges, but at what cost? On one site we managed £380,000 or 26% worth of energy savings, 3.9GWh, 2995 tes CO2 reduction and improvement on Compliance. This was on a substantial sized site but these percentage savings can be replicated on most sites. Strathkelvin ...

Why More Enterprises and Communities Should Turn to Decentralized Wastewater Treatment
Decentralized wastewater treatment solutions aren’t limited to domestic services. As industrial effluent regulations become more stringent, many enterprises can turn to decentralized, on-site wastewater treatment. There are various advantages to implementing this solution, and specific industries can greatly benefit from doing so. However, before diving into those details, it’s ...

Reducing agriculture’s water footprint
Decentralized Water Reuse Can Help Preserve Sources of Fresh Water As the world population grows, so does the demand for food and the need to grow more crops. In many regions of the world, water has become a scarce resource, with supplies affected by climatic changes. Not only does water scarcity limit farmers’ ability to irrigate their crops, but overdrawing groundwater supplies for ...

Review of cost versus scale: water and wastewater treatment and reuse processes
The US National Research Council recently recommended direct potable water reuse (DPR), or potable water reuse without environmental buffer, for consideration to address US water demand. However, conveyance of wastewater and water to and from centralized treatment plants consumes on average four times the energy of treatment in the USA, and centralized DPR would further require upgradient ...

Mobile Unit Cuts Sludge Dewatering Costs for Rural Water Authority
A streamlined method of dewatering digested sludge is helping cut costs for one rural Virginia water authority. The self-contained mobile belt press system is housed in a conventional trailer that can be easily transported from one treatment site to another. According to Bar Delk, general manager of the Louisa County Water Authority (LCWA), Louisa, VA, the new unit eliminated the need to expand ...

UNAS : The key to energy-positive sewage treatment
Water boards are looking for more cost effective ways to operate their WWTP’s and produce clean effluent in an energy neutral manner. As part of that strategy the maximum recovery of energy and nutrients becomes a major objective. A technology upgrade of existing installations reveals possible, whereby cold anammox plays a key role. The recently developed Upflow New Activated Sludge (UNAS) ...

Two-phase anaerobic digestion for class a biosolids at moccasin bend WWTP
The Moccasin Bend Wastewater Treatment Plant (WWTP) provides treatment for the City of Chattanooga, Tennessee and the surrounding region. The City has completed upgrades to the solids handling facilities to treat and dewater the primary solids and waste activated sludge (WAS) from the WWTP. This paper summarizes the process to handle the primary solids and the start-up process. Primary solids ...

Environmental assessment of two small scale wastewater treatment systems: SBR vs CAS
European Water Directive 91/271/EEC introduced a series of measures aimed at protecting sensitive areas against the emission of nutrients originating from waste water treatment plants. There are, however, environmental costs associated with achieving the required level of water quality, such as greenhouse gas emissions resulting from energy consumption. The goal of this study is to assess ...

Inhibition of biological phosphorus removal in a sequencing moving bed biofilm reactor in seawater
Abstract: A new process was developed to achieve denitrifying biological phosphorus removal in wastewaters containing high levels of nitrate and phosphate with a low level of organic matter. This could particularly be useful in recirculating systems such as aquariums or fish farms to prevent accumulation of nitrate and phosphates and to avoid regular cost extensive and polluting water ...

Cost comparison of full-scale water reclamation technologies with an emphasis on membrane bioreactors
The paper assesses the costs of full-scale membrane bioreactors (MBRs). Capital expenditures (CAPEX) and operating expenses (OPEX) of Spanish MBR facilities have been verified and compared to activated sludge plants (CAS) using water reclamation treatment (both conventional and advanced). Spanish MBR facilities require a production of 0.6 to 1.2 kWh per m3, while extended aeration (EA) and ...

Beyond the barriers of water reuse
Water reuse may be the moment’s most talked about treatment industry topic. It’s no wonder that as drought persists in regions throughout the world without sign of subsiding, questions about how we can make the most of our water are being asked. An answer can be found in the ways that we apply membrane bioreactor (MBR) technology. As one of the most central components for water ...
