Polygonum multiflorum or Fo-ti root (traditionally known as He-Shou-Wu in China, or as tuber fleeceflower in North America) is a Chinese plant which is popular due to its rejuvenating properties. The Chinese people use the root of the plant for medicinal purposes such as promoting fertility, restoring hair color and preventing aging effects. Pochtolom polnuyu versiyu2432246.

Commercial dairies have two options – to pretreat and pay to discharge to municipal sewerage or to operate an in house treatment plant. However, there is no one size fits all solution. There are multiple possible configurations for a dairy wastewater treatment plant, In terms of biodegradability, dairy process wastewater is complex – it contains a combination of easily degradable carbohydrates and not so easily degradable proteins and fats.

It is variable in pH also, rapidly changing from alkaline to acidic when lactose ferments to lactic acid. Dairies are multi product factories and the contents of pollutants in the wastewater will change with the start of each new cycle in the production process. This lack of consistency needs to be addressed by the treatment system. Wastewater Treatment Plant Design Software Free Download Technologies Used in Dairy Wastewater Treatment Dairy wastewater needs complex treatment prior to discharge in order to prevent environmental damage. This is due to the high concentration of organic materials including protein, carbohydrates, fats, grease and minerals that elevate BOD.

Moreover, dairy factory cleaning processes generate wastewater containing detergents and cleaning agents that increase COD. Although there are many ways to reduce BOD and COD, biological treatment is the main method using aerobic, anaerobic or a combination of both technologies within a dairy wastewater treatment plant. Steps in the Treatment of Dairy Wastewater Mechanical treatment of dairy wastewater involves filtering out suspended solids with a mechanical screen. This reduces the organic load and protects the subsequent treatment equipment from blockages. An equalization/buffer tank will hold 6 – 12 hours of influent in order to smooth fluctuations in the flow. Supplying air at this stage helps to mix the wastewater and regulates the consistency for the next treatment stage. FOG removal usually follows flow balancing in a conventional dairy wastewater treatment plant.

Sewage Treatment Plant Sewage Treatment Plant Sewage treatment has a number of benefits. For example, sewage treatment ensures that the environment is kept clean, there is no water pollution, makes use of the most important natural resource; water, the treated water can be used for cooling machines in factories and industries, prevents the outbreak of waterborne diseases and most importantly, it ensures that there is adequate water for other purposes like irrigation.

Sewage Treatment Plant Installation If you are considering a new installation of a Sewage Treatment Plant or Septic tank you need to know that the system you are considering suits your needs. We can recommend and install a waste system after conducting a thorough site visit to determine both current and future requirements. • Our fully qualified engineers are able to recommend systems from several manufacturers ensuring a perfect fit for your requirements. We will then carry out the full installation from initial excavation to final commissioning and testing; this ensures that you have peace of mind that you are dealing with one contractor from start to finish. • Once completed we can put in place a service schedule to ensure that your new installation and equipment will continue to run efficiently.
