ELECTROFLOTATION TREATMENT OF DAIRY WASTEWATER: CHEMICAL-TECHNOLOGICAL ASPECTS

Refinery Wastewater Treatment: A true Technological Challenge

Crude oil and condensate refineries generate a large amount of wastewater that has both process and non-process origins. Depending on the type of crude oil, composition of condensate and treatment processes, the characteristics of refinery wastewater vary according to a complex pattern. The design and operation of modern refinery wastewater treatment plants are challenging and are essentially t...

Treatment of Dairy Wastewater Using Pilot Scale Tricking Filter

A pilot scale trickling filter and secondary sedimentation are used to evaluate the feasibility of this process for the treatment of raw dairy waste. The BOD in the raw waste of 252 to 1200 mg/l is reduced 50-73% by a single stage and a further 17-55% by sedimentation tank. Treatment efficiencies are determined at various waste strengths and influent flow rates. With a loading rate of 5-12 kg B...

A Correlation Study on Physico-Chemical Characteristics of Dairy Wastewater

The dairy industry has important to day-today in human life. Dairy industry involves processing of raw milk into products like milk, butter and cheese, etc., and generates 1 to 3 times the volume of milk produced. Knowledge on the physico-chemical characteristics of dairy wastewater is essential in the design, operation, collection and treatment as well as disposal facilities for the effective ...

Dairy Wastewater Treatment using Three-Stage Rotating Biological Contactor (NRBC)

Dairy wastewater is enriched in organic matter (about 45-72 g/l, COD) and also contains biodegradable carbohydrates. A three-stage system, NRBC was fabricated as a bench scale unit for lab experiments, to remove organic carbon from the whey. The fabricated NRBC had several advantages, such as quick start-up, high biomass concentration and was additionally able to handle high organic loading rat...
