Industrial Pond Treatment
This small municipality was experiencing difficulty in maintaining dissolved oxygen levels in their industrial ponds. During the processing season, they were receiving 3MGD of industrial wastewater from tomato and green pepper processors. During the previous season, they had been out of compliance on numerous occasions and received several complaints from the public concerning odors from the ...

Reclaimed municipal wastewater for forage production
This study aims to evaluate the possibility of using reclaimed municipal wastewater for agricultural purpose. We assessed the validity of municipal wastewater treatment, analyzing its chemical characteristics before and after the biological stabilization by pond treatment (WSP). The reclaimed municipal treated wastewater (TWW) was used to irrigate Cenchrus ciliaris. Experiments were carried ...

Fire water storage - Case study
Project Situation A Georgia based retail distribution center experienced algae problems in a fire water storage pond 200 feet long and 75 feet wide – 15,000 square feet or about one-third acre. The filamentous algae in the pond caused clogging of the screens and pumping system. An alternative to chemical treatments was desired to control the algae. Products/Technology Used BioWorld was ...

Dynamics of
Aeromonas species isolated from wastewater treatment systemAeromonas are widely distributed in the aquatic environment, and are considered to be emerging organisms that can produce a series of virulence factors. The present study was carried out in a sanitary sewage stabilization pond treatment system, located in Lins, State of São Paulo, Brazil. Most probable number was applied for estimation of the genus Aeromonas. Colony isolation was carried out on ...

Improved processing performance in a facultative pond system- Case study
Overview: This is a facultative pond for the wastewater treatment plant (WWTP) serving a town of about 2,000. The WWTP is a continuous flow system with a design flow of 0.16 MG/day, but does receive up to 0.9 MG/day during rainy periods. The facultative treatment pond is 16 acres in surface area, and has a mean depth of 5.5 feet deep with an average slurry/sludge depth of about 9 inches. The pond ...

Ecological swimming pond case study
In spring 2009 LG Sound installed an LG Sonic in an ecological swimming pond in France. This pond has been suffering from the growth of filamentous algae for a long period of time. Even when the algae where removed, they grew back within a couple of days. Swimming or any other recreational use was made impossible in this pond. The LG Sonic products can shift the balance in a watery ecosystem to ...

Milk Processing Wastewater Treatment
A milk processing facility was using a 800 hp evaporator to dispose of their 0.75% solids concentrated milk waste stream. The staff was interested in evaluating the effect of using the Floccin products to capture the majority of the BOD and send this higher % solids/BOD sludge to the evaporator. The idea was to reduce the electric hp by reducing the volume of water going to the evaporator. Their ...

Calibration of a simple model for waste stabilisation pond performance in seasonal climates
The paper describes the calibration of a model for waste stabilisation pond (WSP) performance in seasonal climates, based on the use of readily available climate data sets. Calibration data were taken from a wide geographical area of Canada and the USA, including coastal and moderately seasonal sites. Good agreement with measured values was shown using a biochemical oxygen demand (BOD) decay ...

UV disinfection of stabilization pond effluent: a feasible alternative for areas with land restriction
The purpose of this research was to determine the feasibility of a UV photoreactor for the disinfection of effluent from a polishing pond following a UASB reactor treating domestic wastewater. For this, a 20 mm diameter photoreactor (20.7 litre volume) equipped with four 30 W submerged low-pressure mercury arc lamps was used. Three tests with contact times and doses ranging from 45 to 90 s and ...

Improved Processing Performance in a Facultative Pond System- USINWW-LOC110.001 (ID32) - Case Study
Topics: wastewater, sludge reduction, ammonia, MLSS/TSS, BOD, odor control, short-circuiting Overview: This is a facultative pond for the wastewater treatment plant (WWTP) serving a town of about 2,000. The WWTP is a continuous flow system with a design flow of 0.16 MG/day, but does receive up to 0.9 MG/day during rainy periods. The facultative treatment pond is 16 acres in surface area, and has ...

Effective natural organic matter removal in pond water by carbon nanotube membrane with flocculation/adsorption
A carbon nanotube (CNT) ultrafiltration (UF) membrane was applied to natural organic matter (NOM) removal in pond water treatment. The source water was pretreated by flocculation and/or adsorption prior to the UF process to alleviate permeate flux decline and improve NOM removal efficiency. The performance of a commercial polyethersulfone (PES) UF membrane was compared to evaluate that of the ...

Water Recovery Project
The Commercial Opportunity Fielding considers it a matter of environmental ethics to extract and repurpose anything of value from the waste streams it handles, wherever feasible. For some streams, however, the cost of separation exceeds the value of its components. Such streams require some form of ultimate disposal. For hazardous liquid wastes there are few environmentally acceptable disposal ...

Floating Cover - Water Corporation Western Australia - Case Study
Water Corporation Western Australia. 6000 Perth 2.000 nV wastewater reservoir. "Water Corporation (WA) installed Hexa-Cover in a wastewater treatment pond in Leonora, Gold-field Region. We are happy to say, the installation went very smoothly. To date the effluent quality supplied to the recycled water scheme is much improved as well as the quantity' Leanne Brown. Analyst Water Quality ...

What Limits the Productivity of Acid Mine Drainage Treatment Ponds?
Acid mine drainage (AMD) treatment ponds are very common in the U.S. Appalachian coal region and are the main source of many headwater streams. Though the water that discharges from these ponds generally meets state and federal water quality standards, there is a distinct lack of productivity in most of these ponds. Our first objective was to compare the productivity of chemically-treated, ...

Dredging the Back Nine: Stormwater and Water Treatment Ponds
SRS Crisafulli's FLUMP Dredge was in the news this spring for its role in meeting the opening day schedule at a unique Wyoming golf course. The Casper Star-Tribune reported on the FLUMP's contribution to a remediation effort at the Three Crowns Golf Course, Casper, Wyoming. When we called to find out if the deadline had been met, we were told it was close, within one week. Three Crowns ...

Landfills case study: Space heating with LFG: Small project-big savings
On a typical January morning in Minnesota, a landfill operator is working on the compactor’s transmission. Despite the four inches of snow on the ground, he opens the garage doors in the maintenance building to let out some of the excess heat. Unlike previous winters, this year the operator can afford to crank up the heat in the building while working on equipment because the heat is being ...

Influence of temperature and pH on nitrogen removal in a series of maturation ponds treating anaerobic effluent
This paper presents an evaluation of the influence of pH and temperature on nitrogen removal in a series of three shallow maturation ponds serving as post-treatment of upflow anaerobic sludge blanket (UASB) reactor effluent (approximately 200 population equivalent). Monitoring was from January 2007 to May 2009. Throughout this period, the ponds maintained relatively stable operational ...
