  • Deep ditch minimizes footprint

    A goal of many communities in planning wastewater treatment facilities is to minimize the footprint, reducing land use. To reach this goal, a Chinese municipality built their oxidation ditch to deeper parameter depths than conventional designs but experienced serious process and mechanical issues. Officials found that not all aerators are equal. For tackling this deep ditch activated sludge ...

  • Structural Fabric Cover Minimizes Odor Emissions for Municipal Wastewater Facility

    As municipal and industrial wastewater facilities find them-selves being ever more tightly squeezed by encroaching neigh-borhoods, the minimization of odor emissions becomes a critical operating issue. This was the problem facing the Municipal Authority of Wyomissing in Reading, Pa., operating a 4 million gallon-perday wastewater treatment facility. Located right within the community, this ...


  • Minimizing risks in wastewater reuse: proposed operational principles and guidelines for South Africa

    Treated wastewater represents a significant potential source of reclaimed water for some beneficial reuses. However, public concern over the risks/health-related hazards of wastewater reuse has limited the general acceptability of reuse systems in many countries. It is important to manage the operation of recycled water systems in such a way that it will not adversely affect public health and ...

  • Capturing biogas energy to increase your business profits while safeguarding the environment

    Methane is a biogas produced from swine or cow manure, as well as food processing and meat packing waste. Methane is a natural gas, that when left uncollected, contributes to the harmful greenhouse gases in the earth’s atmosphere. When biogas is captured under a cover and becomes concentrated, it creates a corrosive and toxic byproduct called hydrogen sulfide. The gas generates a rotten egg ...

  • Industrial flue gas desulfurization waste may offer an opportunity to facilitate SANI® application for significant sludge minimization in freshwater wastewater treatment

    This paper reports an exploratory study on the use of a sulfite-rich industrial effluent to enable the integration of a sulfite–sulfide–sulfate cycle to the conventional carbon and nitrogen cycles in wastewater treatment to achieve sludge minimization through the non-sludge-producing Sulfate reduction, Autotrophic denitrification and Nitrification Integrated (SANI) ...

  • Treatment of industrial wastewater

    All industries produce some type of waste product, either from production, maintanance or both. These hazardous and non-hazardous wastes need to be properly stored, treated and discharged to a sewer system or otherwise disposed of. Wastewater treatment is a multi-stage process to renew wastewater before it is discharged to the municipal sewer system. The goal is tio reduce or remove organic ...

  • Comparing Capacity Expansion and Waste Minimization Options at a Chemical Manufacturing Facility

    ABSTRACTIndustrial wastewater treatment facilities that are nearing their capacity limit often have a relief option that typically is not available to municipal treatment facilities. That option is to reduce waste loads coming from the production areas by optimizing manufacturing processes so that less waste is generated per pound of product made. In making the decision between reducing waste ...

  • How to Minimize Solids for Disposal while Meeting Stringent Effluent limits: Industrial Park Case Study

    The Renda Industrial Park (RIP) in TaSheh, Taiwan, was required to expand and upgrade its existing 10,000 CMD (2.6 MGD) treatment system to 23,000 CMD (6 MGD) in order serve its expanding client base, and at the same time meet a new < 100 mg/l effluent COD standard. The existing wastewater treatment system of primary sedimentation and extended air activated sludge with chemically assisted ...

  • Innovative Approaches to RO Concentrate Management: Beneficial Reuse and Concentrate Minimization

    ABSTRACTDesalination of brackish waters and reclaimed waters using reverse osmosis (RO) is often limited by the options available for concentrate disposal, particularly in inland areas. Dewatering the concentrate is alternative approach to disposal but the available thermal and membrane technologies are still cost prohibitive for most applications. Beneficial reuse of the RO concentrate ...

  • Green Roof Media Selection for the Minimization of Pollutant Loadings in Roof Runoff

    ABSTRACTStormwater is a leading cause of water quality impairment in estuaries like the Chesapeake Bay. Green roofs are a potential best management practice for urban areas where land for traditional stormwater practices is unavailable. They are aesthetically pleasing, with excellent water retention ability. However, it is unknown how effective they are at treating stormwater. Typical media ...

  • Wastewater Treat Ability in the Food and Beverage Industry

    Abstract Wastewater treatment is a concern in most industrial sectors. However, the food and beverage industry is potentially more concern than most. The food and beverage industry is traditionally a user of large volumes of water. The cost of water is rising sharply in many countries around the world, often related to the higher costs of delivery of high quality potable water as well as the ...

  • Industrial Laundry

    Problem: For many years industrial laundries discharged their effluent into the local sanitation plant without any restrictions. Now, when applying for a new discharge permit, the laundries are required to meet the new guidelines established by the EPA These requirements are normally as follows: 100 PPM for fats, oils and greases; and 250 PPM for total suspended solids. Some ...

  • Optimizing Wastewater Treatment

    ' Growing volumes of both industrial and municipal wastewater are being discharged to surface waters but the treatment provided frequently is inadequate to protect the desired uses of the receiving waters. With limited resources in terms of both institutional capacity and finance, governments face difficult choices in optimizing their investments in municipal systems and establishing practical ...

  • Heat recovery from wastewater

    Heat recovery from gray water is particularly important in water-intensive industries such as pulp and paper plants, dairies and breweries. Rather than flushing used water down the drain, consider whether a heat exchanging system can help you put that energy to work in your process again. Most plant operators arc aware of the need to save money and reduce the environmental impact of their plant ...
