Egg Processing
Problem: This eggplant, located in Southern California, pro¬duces approximately 6 million eggs per week. During the process and preparation of these eggs, some break and fall on the floor where they are washed into floor drains and mixed with the egg wash water. The mixture of broken eggs and wash water is discharged to a balance tank and then sent through a settling clarifier. The settling ...

Pemex Refinery Decommissioning
The Problem The decision by PEMEX to close their "La Nogalera" petroleum storage facility in Guadalajara, Mexico, involved the demolition of the facility's large storage tanks. Before demolition, the tanks had to be cleaned and all traces of petroleum had to be removed from the tanks. All tanks were pressure washed prior to demolition creating a large volume (9,035 m3) of contaminated wash water ...

Characterization of microbial communities in exhaust air treatment systems of large-scale pig housing facilities
Exhaust air treatment has gained importance as an essential factor in intensive livestock areas due to the rising emissions in the environment. Wet filter walls of multi-stage exhaust air treatment systems precipitate gaseous ammonia and dust particles from exhaust air in washing water. Microbial communities in the biomass developed in the washing water of five large-scale exhaust air treatment ...

Optimization analysis of separation conditions of washed water containing a lead complex and characterization of the precipitation products
Presently, the large amount of industrial leaded wastewater creates a great challenge to both environmental governance and wastewater recycling. Lead complexes in washed water must be removed mostly before the washed water can be recycled. This paper reports the mechanism and factors of removing Pb complexes in simulated washed water by the sulfide precipitation method. The reaction time, ...

Building on tradition
A new technology is making a name for itself in potable water filtration. And, according to AMT Systems, it is the most cost-efficient advance since the introduction of the dual media filter. Your filters need to be washed every day. What would your energy, water and waste treatment saving be if they only required washing every four or five days? You need to increase the output of the works. Are ...

Minimizing water consumption and health problems at the same time (Malaysia)
PROBLEM A glue manufacturing plant in Malaysia had a belt press, but they had always faced clogging problems because of the sticky characteristics of sludge dewatered. For its operation and maintenance, they needed to use a great amount of water, as much as 36 m3/day. Furthermore, high-pressure water cleaning generated loud noises and the misty sludge scattered by the cleaning process also ...

Recovery of microorganisms on fabric materials after low water temperature washing with non-oxidizing acidic bleaching formulation by culture method
The recovery of microorganisms to different fabrics was evaluated after a washing process combined with a food-grade non-oxidizing acidic formulation and low washing water temperature. Cotton, polyester and a polyester/cotton blend fabric samples were inoculated with Escherichia coli, Listeria innocua and Saccharomyces cerevisiae, then dried for 1 day. They were separately placed in a simulated ...

Treatment of tunnel wash water and implications for its disposal
The use of road tunnels in urban areas creates water pollution problems, since the tunnels must be frequently cleaned for traffic safety reasons. The washing generates extensive volumes of highly polluted water, for example, more than fivefold higher concentrations of suspended solids compared to highway runoff. The pollutants in the wash water have an affinity for particulate material, so ...

J.C. Chambers WWTP City of Berea, KY
The City of Berea was operating with outdated belt press technology which had high maintenance requirements and inadequate operating capacity. During the latest expansion of their facility, the plant evaluated various options for increasing the hydraulic throughput and reliability of their dewatering system. BDP was the press of choice due to the superior performance of the 3DPTM belt filter ...

Sources of organic matter in first flush runoff from urban roadways
This study aims to explore the influential sources of organic matter in first flush runoff from urban roadways by comparing organic carbon content and particle size distribution in road dust with those from discharge from vehicles during rainfall. Samples on first flush runoff and road dust were collected from urban roadways. In addition, vehicle drainage was assumed to flow from vehicles ...

Filter fabrics for sugar plants/ Sugar industry filter cloth
Mostly the raw materials for sugar production will be sugar cane and sugar beet, according to the different clarify method, which can be divided into carbonized sugar (lime+CO2) and sulfurized sugar (lime+SO2) sugar, though the carbonized sugar more complex and need much investment on the machines and clarificant, but the general processing principle and procedures are similar. And the ...

Carbon recovery from screenings for energy-efficient wastewater treatment
The energy content of screenings from six municipal wastewater treatment plants (WWTPs) was examined. Hourly samples of separated screenings were taken over 24 hours at three of the plants to illustrate diurnal variations. To recover the chemical energy, which usually leaves the WWTP with the screenings, a screenings wash press was used to transfer organic matter from the solid into the ...
