Sludge Digestion/Thickening Optimizes Treatment - Case Study
Overview: Big Park Domestic Wastewater Improvements District in Arizona had constructed a new 500,000 gallonsper day biological wastewater treatment system in 1997. As time passed, the aging plant was unable tokeep up with increasing demands. Challenge: In 2012, the District started working with Sunrise Engineering to find a solution that would work in theirexisting plant. Sunrise Engineering partnered with Aeration Industries International to upgrade theequalization basin, as well as the sludge digester/thicken...
Treating wastewater as a resource
A number of UK landfill operators are turning wastewater into a resource by utilising OTT monitoring and control systems to manage the irrigation of Willow crops (for renewable energy generation) with pre-treated effluent. BackgroundLeachate from landfill sites represents a significant potential environmental liability, extending long into the future after a landfill site has closed. Conventional treatment and disposal options involve biological treatment and consented discharge to either the wastewater treatment...
GWT Electrocoagulation Wastewater Treatment – An Application To Sustainably Reuse Textile Wastewater
The textile industry is a water consumption intensive industry. Water is utilized for cleaning the raw material, and for the different steps in the textile dyeing process. Due to the effects of water scarcity and stricter environmental regulations, the cost of fresh water utilization has increased worldwide. In addition, the textile industry is faced with pressure by government regulators to move toward sustainability, by reducing the consumption of water, while internal pressures to maintain or increase profit...
Biofiltration WWTP 50.000 PE
The aerated upflow biological filtration (biofiltration) is a technology which is today successfully used in more than 500 European wastewater treatment plants. Among this, the one of Sallek Valley, in Slovenia, differs by a two stage biofiltration and a part-recirculation of sludge from thickener to increase the COD concentration needed for denitrification. This process allows an advanced denitrification- nitrification in a very compact way and low operation costs. The results of the wastewater treatment plant...
Wastewater-Solids Dewatering Odor Control - Case Study
BackgroundThe Milan Wastewater Treatment Plant, located just south of Moline, Illinois, is a 1.7 MGD (6,434 m3/day) activated sludge facility with an average wastewater flow of 700,000 gpd to 800,000 gpd. This facility dewaters primary sludge using a belt filter press (Figure 1). The press operates an average of three times per month, 8 hours per day at a pump rate of 100 gpm. The sludge is dewatered from 3-4% solids to about 23% solids. ProblemOn days when the bio-solids from the primary settling tank are...
