This article describes the effectiveness of bioaugmentation in the sewer network as a strategy to reduce sludge production. Sludge is an obvious by-product generated from the physical, chemical and biological treatment processes of a wastewater treatment plant (WWTP) as shown in Figure 1. Sludge management, which includes treatment, hauling, and disposal, is one of the biggest burdens facing ...
A market leader in biomass engineering has launched a 24-hour biological safeguard system to protect organisations operating treatment plants against discharging illegal levels of ammonia. North East-based Cleveland Biotech (CB) has seen an increase in enquiries for its Amnite NS5000 product from companies which are obliged to prove to authorities they adhere to legal constraints over ...
Sludge is an obvious by-product generated from the physical, chemical and biological treatment processes of a wastewater treatment plant (WWTP) as shown in Figure 1. Sludge management, which includes treatment, hauling, and disposal, is one of the biggest burdens facing municipal plants. The costs of sludge management account for 55% of the total WWTP operating cost and 35° o of the capital ...
What is it? The bioaugmentation is an innovative technology which consists in an increase of selected bacteria to help naturally the biological process of organic compounds degradation. It is proper to dose in any effluent type and wastewater treatment system, which no longer has enough capacity or has an inefficient performance. These products facilitate the reduction ...
Problem DefinitionIn 2004, the site was an active manufacturing facility with plume trichloroethene (TCE) concentrations ranging from 1 to 20 milligrams per liter (mg/L), and hexavalent chromium (Cr[VI]) ranging from 0.5 to 7 mg/L. Intermediate degradation products of TCE were present in only trace concentrations in this primarily aerobic aquifer. The site source area was excavated in March ...
Selecting a remediation alternative that is compatible with the natural soil and ground water conditions is not only a more sustainable approach, but leads to significant savings. Comparison between bioaugmentation and other remediation methods in the five recognized sustainability criteria demonstrates the advantages of bioaugmentation. While this paper is nota complete quantitative analysis, it ...
The US Department of Defense (DOD) has completed pilot-scale work on the 'MAG-1' site at Fort Dix, NJ, to test suitability of anaerobic bioremediation for an aquifer with low pH. Project results will be used to design full-scale ground-water treatment at MAG-1. In addition, technical criteria gained from the demonstration will be integrated into DOD’s remediation strategy for its many facilities ...
The use of Bioaugmentation has been shown to be a very effective method of restoring activity in a wastwater treatment plant treating the effluent from cheese production. The plant had lost activity and in this case activity was restored without removing the existing dead biomass. This presented a considerable challenge and resulted in considerable savings for the client since the dead sludge ...
ABSTRACT The New York City Department of Environmental Protection (NYCDEP) has developed and is utilizing a unique sidestream treatment process that provides for nitrogen removal from high ammonia anaerobically digested sludge dewatering centrate, while producing predominantly nitrite as the ammonia oxidation product (Katehis, 2002; Fillos, 2005). The biomass produced in the sidestream ...
Introduction This packaging plant finishes 'heavy' beer, a liquid concentrate, into the well-known canned and bottled products. The plant handles 50,000 barrels per week and generates over 350,000 gallons of wastewater per day. Wastes are treated at the plant's 0.5 MGD waste treatment facility which operates under a standard discharge NPDES permit. Waste beer is the main constituent of ...

Abstract The effectiveness of In-Pipe Technology (IPT) patented sewer collection system engineered bioaugmentation on i) influent wastewater loads to wastewater treatment plant (WWTP), ii) WWTP performance, and iii) effluent quality, was a demonstrated at a domestic sequencing batch reactor (SBR) WWTP (Sewer District #20) in Suffolk County, Long Island, New York in collaboration with the ...
The risk driver for remedial action on many sites is potential vapor intrusion hazard. While mitigation of the vapors entering the structure can reduce the risk to an acceptable level, there are associated long-term monitoring, operation and maintenance costs. Bioremediation of the source of vapors can reduce the risk and eliminate long-term costs. The vapor intrusion risk is managed by ...
Problem DefinitionThe site is a former manufacturing facility, where a historic trichloroethene (TCE) release created a plume 1,100 feet wide and 7,000 feet long averaging 3,600 micrograms per liter (μg/ L) TCE, with a groundwater velocity of about 2 feet per day. Prior to biostimulation with electron donor, the groundwater conditions ranged from aerobic to mildly reducing and Gene-Trac DNA ...
ProblemA trichloroethene (TCE) release at the site in the early 1980’s led to concentrations of TCE and cis-1,2-dichloroethene (cDCE) as high as 592 and 90 milligrams per liter (mg/L), respectively, in the source area, where dense non-aqueous phase liquid (DNAPL) was suspected to be present. The downgradient plume had concentrations of TCE, cDCE, andvinyl chloride (VC) as high as 2, 34, and ...
Author’s note: The terms mill and plant are used interchangeably in this article to describe an industrial manufacturing unit, such as a Pulp & Paper Mill, Petroleum Refinery, Chemical Processing Plant, Meat & Poultry Processing, etc. Plant (or mill) outages come in two types – scheduled and unplanned. Scheduled outages are generally annual affairs at roughly the same ...
A man-made natural fibre producer had produced a new high strength, fibrillated cellulosic fibre derived from wood pulp destined for use in garment manufacture. As a result of the IPC authorisation attached to the production of this product it became necessary to establish the biodegradability of various effluent streams leaving the production plant. In order to evaluate the feasibility of ...
