December 12, 2022Membrane filters can be defined as a microporous film that serves as a barrier, allowing the flow of fluids or gasses while preventing the passage of particles and microorganisms. These filters have specific ratings for their pore sizes which is vital to keep the microorganisms or particles which are bigger than the size of their pores through the process of surface capture. Membrane filtration utilizes pressure in order to force water or any other kind of carrier (fluid or gas) through a porous or semi-permeable membrane. This process separates the particulate matter that's suspended from the soluble and carrier components.

Regardless of whether it's a high school science laboratory, a medical research laboratory or scientific research facility, laboratories are hazardous environments and certain safety measures need to be implemented to prevent accidents. The following safety tips can help avoid common hazards and accidents in a laboratory.Â
- Basic Safety Protocols
Try to avoid working alone in a building and never work alone in a laboratory if the work you are doing presents an element of danger. Alert others to potential dangers when working with hazardous equipment or materials, or if there are any unusual hazards or conditions present. A laboratory is not the place for joking around. Distracting or startling someone working in a laboratory environment can cause an accident.
- Know Where to Go and What to Do in an Emergency
It is no use waiting for an accident to happen before you read through safety protocols and procedures. Understand what the safety rules and regulations are and what to do if there is

November 09, 2022Bacterial and viral outbreaks in wild animal colonies can have a devastating impact on wildlife populations, and sometimes their long term conservation too. Early diagnosis can help wildlife managers understand what pathogens they are dealing with so they can implement measures to prevent the spread of disease where possible.

October 14, 2022Ceramic membranes have long since been regarded for their specific advantages in separation techniques, notably chemical and thermal stability, high flux rates, and potential for regeneration. Made with an α-Al2O3 support layer, the intermediate layers and the membrane are made of TiO2 or ZrO2 depending on pore size.Â

October 13, 2022What is the purpose of spacers and shims used with the membrane test cells, and do I need them? Crossflow velocity (CFV) refers to the linear rate of flow of the feed solution as it passes tangentially over the surface of the membrane filter and is measured in meters or feet per second. Some of the feed solution will permeate through the membrane filter, while the balance will flow along the surface of the membrane and collect as concentrate that can be recirculated through the system. The crossflow velocity has a direct impact on the fouling rate and the occurrence of concentration polarization — where a concentration gradient forms in the fluid adjacent to the membrane surface.

October 13, 2022Oktoberfest is an annual beer festival held over the course of two weeks during September-October in Munich, Germany Its origins date back to October 12, 1810, when the festival was first held to celebrate the marriage of Prince Louis of Bavaria, who later became King, to Princess Therese von Sachsen-Hildburghausen. Over the years, the festival has evolved to include an amusement park and fun-fair, food and drink stalls, and several large and lively beer halls, where much of the merry-making takes place.

September 16, 2022The World Health Organization (WHO) defines air pollution as the "contamination of the indoor or outdoor environment by any chemical, physical or biological agent that modifies the natural characteristics of the atmosphere." This International Clean Air Day, let's try to clean up our act and strive for clean air and blue skies by making a concerted effort to reduce our carbon footprint.

September 16, 2022What is Chemical Oxygen Demand?. Chemical oxygen demand (COD) is the amount of dissolved oxygen needed to oxidize organic matter present in water. COD testing is conducted to determine how much organic matter is present in a water sample and how much oxidation will occur. COD testing can also be used to determine the levels of inorganic chemicals present in a sample, [1] and is used to quantify pollution levels in water. A higher COD value indicates greater pollution levels in a water sample.
