ClearFox are specialists in the design and manufacture of plug and play modular solutions for all food processing wastewater. Our technical ability and experience make us the best choice for your project. We have a range of process technologies that can be combined in a modular arrangement to deal with any type of food processing wastewater. These include pre-treatment, dissolved air flotation, biological treatment, clarifiers, disinfection. We can also incorporate ultrafiltration to allow the wastewater to be recycled and used as process water.

ClearFox modular industrial wastewater solutions have the following advantages:

• Low operation costs
• Modular
• Automatic operation
• Low purchase price
• Process and effluent guarantees

Application Description:

In the food processing Industry the water quality may significantly affect the products, therefore high quality water is used in production after having been treated by chemical dosing, coagulation, sand filtration, activated carbon filtration, degasification, and other processes. Water use starts with conditioning raw materials such as soaking, cleaning, blanching and chilling. It continues with cooling, sanitising, steam generation for sterilisation, power and process heating, washing and rinsing cans, bottles, cleaning equipment, containers and finally, direct “in-process” use. In especially the beverage manufacture carbon dioxide gas, sweeteners like sugar or syrup and flavours may be dissolved into the water. Wastewater volumes vary with the products manufactured and factory type. Up to 10 times the amount of water in relation to product ingredients is needed and has to be treated.

Wastewater composition:

The composition of wastewater from food processing factories are characterised by high BOD, SS, and sugar or oil concentrations, as well as emitting odour.

Wastewater Characteristics:

The characteristics and volume of wastewater discharged from food processing factories vary with the products and production procedures. Water plays a key role in food processing. It is used in every step of the technological lines, including cleaning and washing, disinfection, heating and cooling. Water requirements are huge.

 The three major categories according to their origin and composition are:

1.Processing water:

Processing water is formed in the in special coolers and condensers, as well as condensates from evaporation. In general, processing waters lack pollutants and, after minimal pretreatment, they can be reused or discharged together with stormwater. Water reuse is possible, typical applications are hot water and steam production as well as membrane cleaning.

2.Cleaning wastewater:

Cleaning wastewater usually comes from washing equipment which is in direct contact with the products manufactured. It also includes spillage, CIP effluents or equipment malfunction and even operational errors. Over 90% of organic solids in effluents come from manufacturing residues. These effluents are in large quantities and are highly polluted, thus requiring further treatment.

3.Sanitary wastewater:

Sanitary wastewater is found in lavatories, shower rooms, etc. Sanitary wastewater is similar in composition to municipal wastewater and is generally piped directly to sewage works, but it can be used as a nitrogen source for unbalanced effluents before a secondary aerobic treatment.
