PWTECH Hybrid Bnr Plant Performance, Dunsborough Wastewater Treatment Plant - Case Study
The Dunsborough Wastewater Treatment Plant is located in Western Australia and has capacity to treat up to 1 million gallons of municipal wastewater daily. The plant was commissioned in May 2000 and is designed to prevent nutrients from entering the environmentally sensitive Geographe Bay. The wastewater is treated to tertiary standards and much of the effluent is used to irrigate a bluegum ...

Shrimp Processing Wastewater Treatment
These jars show the treatibility with Floccin J and wastewater from cooked shrimp. The initial untreated water had a TSS of 1,230 ppm and a BOD of 3,000 ppm. The addition of 0.10 grams of Floccin J in 100ml (8.34 lbs/1,000 gallons) created a tight flock and a very clean effluent water quality. The treated TSS was less than 10 ppm and the BOD was 200 ppm. There was a significant amount of oil ...

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 ...

Meat Processing Wastewater Case Study
Nordfjord Kjott R.A. - Meat Processing Plant - Stryn, Norway The Challenge: Located deep in the mountains of Stryn,, the original plant consisted of an inlet pump station and Salsnes filter for pretreatment, fat removal and a Salsnes filter for post treatment. The plant also had 8 concrete tanks which were not in use. The municipality was faced with equivilent loading rates of 10,000 PE and ...

Peach Processing Wastewater Treatment
A major fresh pack operation of peaches and nectarines needed a screening system to remove the labels and peach fuzz from their wash water before it was pumped from the pond for irrigation use. Flow to the pond is a steady flow of 50 gpm, rising to 600 gpm during periodic draining of the peach coolers and washing systems. The water is a combination of wash water, labels and fuzz from the fruit, ...

Grease Processing Facility Wastewater
Yellow & Brown Grease Processing for Biofuel This facility takes in yellow and brown grease and processes it to recover the organics for biofuel. The resulting wastewater generated is shown below on the left. The pH quickly drops to 4.67 as the organics anaerobically decompose thereby dropping the pH. Caustic was used to raise the pH to 6.4 and the addition of Floccin 909 produced the ...

Design development of an electrocoagulation reactor for molasses process wastewater treatment
The impact of electrode corrosion behaviour, reactor geometry and current density on electrocoagulation efficiency were investigated for the treatment of molasses process wastewater. Two laboratory-scale vertical plate electrocoagulation reactors were used for this investigation: the first being a low aspect ratio bath reactor with a low specific electrode area, while the other was a high aspect ...

Mixed micelles-mediated dephenolisation of table olive processing's wastewaters
Olive processing wastewaters account for highly pollutant agro-industrial effluents. Their phenolic compounds are responsible for their toxicity. Those natural compounds have to be degraded or recovered before any discharge into the environment. This investigation deals with the extraction and concentration of the phenolic compounds into an aqueous phase using a mixture of nonionic/anionic ...

Enzymatic oxidation of phenolic compounds in coffee processing wastewater
Peroxidases can be used in the treatment of wastewater containing phenolic compounds. The effluent from the wet processing of coffee fruits contains high content of these pollutants and although some studies propose treatments for this wastewater, none targets specifically the removal of these recalcitrant compounds. This study evaluates the potential use of different peroxidase sources in ...

Toxicity reduction and biodegradability enhancement of cork processing wastewaters by ozonation
Biodegradability enhancement and detoxification of cork boiling wastewater (CBW) are required for the successful implementation of biological treatment options. We studied the possibility of achieving these goals through ozonation pre-treatment by experimenting on the effect of ozone dose and pH. The CBW used had a pH of 5.81, a chemical oxygen demand (COD) of 1,865 mg L−1, a biochemical ...

Development of downflow hanging sponge (DHS) reactor as post treatment of existing combined anaerobic tank treating natural rubber processing wastewater
Conventional aerated tank technology is widely applied for post treatment of natural rubber processing wastewater in Southeast Asia; however, a long hydraulic retention time (HRT) is required and the effluent standards are exceeded. In this study, a downflow hanging sponge (DHS) reactor was installed as post treatment of anaerobic tank effluent in a natural rubber factory in South Vietnam and ...

A momentary look on food processing wastewater treatment
The qualities and volume of wastewater released from food processing industries have created significant concerns for ecologists all over the world. However, the amount and quality of wastewater vary from industry and food processing types. While some food organizations prefer to discharge the wastewater in a particular period, some go for dispatching polluted water all over the year, which has ...

The wastewater treatment of the food industry
The wastewater treatment is a process which is used to recycle the wastewater into an effluent that can be reused again. This treatment helps in removing all the impurities from the water. Many industries are involved in this type of treatment to make use of water and not to waste it. Due to the scarcity of water, this type of water recycle is necessary. Many foods and beverage processing ...

PEWE Williams Sausage Case Study
For over 55 years Williams Sausage operated with the belief their Country Flavor Formula would sell sausage. They blend only the finest whole hog cuts flavored with a family recipe of the finest herbs and spices, without adding sugar. It worked, so starting with a single truck the firm grew from western Tennessee to a national firm which has required many plant expansions. And with the focus on ...

Site Selection for Food Processing Facilities Wastewater Treatment
Food processors face an ever changing production schedule which depends largely on the growers products, their finished product customers, labor, and the current market pricing. Many facilities are relocating or looking to relocate to decrease the fixed cost of overhead and labor to try and obtain a competitive advantage over their competitors, which can be only a few cents per pound of finished ...

Electrocoagulation (EC) Process for Wastewater Treatment
Electrocoagulation (EC) process is a cutting-edge technology that is increasingly being used for wastewater treatment. This innovative process involves the use of electric current to remove impurities from water, making it a cost-effective and eco-friendly alternative to traditional wastewater treatment methods. In this article written by our experts, we will discuss the step-by-step process ...

Ammonia Reduction By Bioremediation
Specially selected microbes treat poultry processing wastewater to reduce nitrogen and organic waste levels Petrox DN organisms reduced ammonia-nitogen and BOD levels in the same wastewater reactor. The organisms in Petrox removed 40% of the ammonia-nitrogen in 48 hours. This reduction stabilized the concentrations in wastewater effluent to an acceptable level eliminating permit ...
