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, ...

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 ...

Poultry Processing Facility Wastewater Treatment

This chicken slaughter and processing facility has a wastewater system that treats 1.2 MGD. Their process uses ferric chloride as the coagulant, caustic to stabilize the pH and an anionic polymer prior to separation in the DAF units. The facility also does some further processing with addition of seasoning and brines which add TDS/EC to the water. The ferric/anionic polymer combination is ...

Wastewater treatment in a milk-processing company

Description of the plant The accruing wastewater from the production of cheese and milk products is collected in a centralised pump sump and given to a first pre-treatment step. This step includes a separation of bigger parts by a sieve and a flocculation step with a dissolved air flotation for elimination of fats and cheese particles. After that, the pre-treatened water is buffered ...

Integrating anaerobic processes into wastewater treatment

Over the past decade, the concept of anaerobic processes for the treatment of low temperature domestic wastewater has been introduced. This paper uses a developed wastewater flowsheet model and experimental data from several pilot scale studies to establish the impact of integrating anaerobic process into the wastewater flowsheet. The results demonstrate that, by integrating an expanded granular ...

Cavitational technology in wastewater treatment process

Cavitation is one such recent technique which has been found to be substantially beneficial in wastewater treatment. Cavitation can be described as formation, growth and sub-sequent collapse of cavities releasing large magnitudes of energy locally, creating conditions similar to hot spots, and also generating strong oxidizing conditions by way of ...

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 ...

Domestic wastewater treatment with CEPT-wetlands process

This study aimed to develop an effective process with less construction and operation cost and with flexibility of meeting different temperature requirements, namely CEPT-construted wetland processes. To reduce the chemical cost for the CEPT process, fly ash was firstly utilised to develop an efficient compound coagulant. The lab-scale experimental results showed that with low Fly Ash Coagulant ...

Sustainable wastewater treatment chemicals in a food processing plant

A food ingredients manufacturer was using an inorganic aluminium metal salt with pH correction to treat their effluent. This chemical regime refused to give them any real control over their effluent characterisation. Their effluent plant required constant monitoring and adjustment. The inability to control the characterisation of the effluent exiting the site meant non-compliance to the ...

Metal Processing Facility 2 Wastewater Treatment

Integrated Engineers, Inc. conducted the below treatability on a Metal Processing facility that uses soluble metal cutting oils in their machining process; below are the results. The treatment required no pH adjustment from the 7.0 pH. The best product was treated with 0.679 grams of Floccin-HP (powdered) in a 100 ml sample and required moderate mixing. The dosage equates to a treatment of 56 ...
