Dairy industry has grown in most countries of the world because the demand for milk and milk products has steadily risen. Simultaneously, the production of milk per head of cattle has also grown as a result of advancements in veterinary science .

The dairy industry produces different products such as pasteurized, condensed, skimmed and powdered milk, yogurt, butter, different types of desserts and cheeses and sometimes cheese whey .  Dairy industries release large quantities of wastewater often in the order of thousand cubic meters/day. It is estimated that dairy industry uses 2 to 5 L of water per L of milk processed. Most of the wastewater produced in the dairy industry results from cleaning of transport lines and equipment between production cycles, cleaning of tank trucks, washing of milk silos and equipment malfunctions or operational errors. These wastewaters are rich in biodegradable organics and nutrients. The Dairy Waste Water is similar to most other agro-industries wastewaters, characterized by high BOD and COD concentrations representing their high organic content. The main contributors to the organic load of these wastewaters are lactose, fats and proteins. If not treated, High concentration of organic matter in dairy wastewater causes pollution problems to surroundings.

Dairy effluents contain dissolved sugars and proteins, fats, and possibly residues of additives. The key parameters are biochemical oxygen demand (BOD), with an average ranging from 0.8 to 2.5 kilograms per metric ton (kg/t) of milk in the untreated effluent; chemical oxygen demand (COD), which is normally about 1.5 times the BOD level; total suspended solids, at 100–1,000 milligrams per liter (mg/l); total dissolved solids: phosphorus (10–100 mg/l), and nitrogen (about 6% of the BOD level). Cream, butter, cheese, and whey production are major sources of BOD in wastewater. The wastewater may contain pathogens from contaminated materials or production processes. A dairy often generates odors and, in some cases, dust, which need to be controlled. Most of the solid wastes can be processed into other products and byproducts.

By utilizing WyunaSep technology, dairies can recover fats for non human consumption from their waste stream and sell it in the market.

WyunaSep Hydrocyclone use centrifugal force to Physically separate fats or solids from water or water based solutions regardless of the flow rate.

Fluids containing fats are fed tangentially into the hydrocyclone. As the mixture flows through the unit, it accelerates sending the lighter phase (fats) to the centre for removal through the overflow. Cleaned water reports to the underflow.

Our solid separators are equally efficient, sending unwanted solids directly to the underflow stream. Clean water flows through the overflow. Simples !!

You can use it separately or together, WyunaSep offers a single, cost effective system for your dairy process.

You retain valuable product while unwanted waste is removed in on efficient operation.

Yield is improved End product quality and process performance are greatly enhanced. And downstream equipment, such as ultra-filtration, are protected.


With the help of WyunaSep Fats recovery system and ETP-Pre treatment system.
You can recover all the free fats & proteins from effluent water
Increases good quality of recovered Fats and Proteins, as it is recovered before any treatments in ETP.
Reduces load on ETP further treatment.
Increases  ETP and Aeration efficiency, by removing the Fats and solids from its water.
Reduces  frequent maintenance requirement.
Saves operators time and efforts to handle dirty water.
Due to reduction in Fats and solids prior to ETP reduces load on pumps and chemical dosing in further treatments.
