Worldwide, environmental regulatory establishments are setting strict standards for discharge of wastewaters from industries. Anaerobic digestion is an environment friendly technology to treat industrial wastewaters. Anaerobic digestion is a series of processes in which microorganisms break down biodegradable material in the absence of oxygen. For the treatment, cheese-dairy wastewater is taken...

The effluent guidelines and standards for the feedlot category were first published in 1974 (1). The feedlot category includes beef, dairy, swine, poultry, horses, and sheep. The current regulations are based on a three tier structure and apply to all operations with ≥ 1,000 animal units (AUs) and some with ≥ 300 AUs , if they meet certain risk based conditions. In the case of the poultry indus...

BOD (Biochemical oxygen demand) is the pollution index of any water sample. One of the main factors influencing the estimation of BOD is the nature of microorganisms used as seeding material. In order to meet the variation in wastewater characteristics, one has to be specific in choosing the biological component that is the seeding material. The present study deals with the estimation of BOD of...

We assessed the bioflocculant production potentials of a consortium of two marine bacterial species belonging to the Oceanobacillus and Halobacillus genera, isolated from sediment samples of Algoa Bay in the Eastern Cape Province of South Africa. Cell free culture broth of the consortium had a flocculating activity of 98.3%, which is higher than those of pure cultures of the individual species....

Airborne endotoxins in occupational environments are a potential respiratory hazard to individuals. In this study, airborne endotoxins were collected using open-face and button aerosol samplers from inside animal housing units and downwind from agricultural production sites and a wastewater treatment plant. Filter extracts were then diluted to examine the effect of interfering substances on the...

The use of different organic carbon sources in the denitrification of wastewater containing 2500 mg nitrates/L in a SBR was studied. Three alternative sources of carbon were tested: wastewater from a sweet factory, a residue from a soft drinks factory and a residue from a dairy plant. The first two are sugar-rich, whereas the third presents a high content in lactic acid. Maximum specific denitr...

The biomass productivity and nutrient composition of microalgae, such as Chlorella vulgaris, depend on the cultivation process content growth media. Thus, in this study aimed to investigate C. vulgaris cultivated fish dairy cattle wastewaters. Thirty wastewater samples (2.5 L) were collected from system production. Microalgae Erlenmeyer flasks containing 10 mL microalgae 1,790 under constant li...

Dairy wastewater management is a major concern for many milk-producing countries as it serious nuisance to the surroundings when disposed of untreated, increasing organic load and foul smell. Microalgae remediation an easy cost-effective treatment treat effluent simultaneously enhance few agronomic traits. In this research, phytoremediation technique was validated by treating dairy using microa...
