Water contamination can have a deleterious effect on humans. What is the impact of wastewater on human health? Some illnesses from wastewater-related sources are relatively common health problems. Water borne diseases like gastroenteritis can result from a variety of pathogens in wastewater; other important wastewater-related diseases include hepatitis A, typhoid, polio, cholera and dysentery. Outbreaks of these diseases can occur as a result of, drinking water from […]

We all know wastewater is harmful. But how harmful, and in what different ways? This is the subject of my current newsletter. Aquatic Organisms Do Aquatic organisms exposed to pharma products live or die? Antibiotics, blood lipid regulators, analgesics, anti-inflammatory drugs, and beta-blockers, fragrances [musks], skin care products, disinfectants and antiseptics are the common ingredients o domestic wastewater. Physiological responses on organisms in the aquatic […]

Prior to the advent of microscopy and discovery of microorganisms, types of classes of living beings were either plants or animals Microbes did not fit into either of the traditional classes. A third classification to accommodate these, protists came into being Many protists have one cell, but even the multicellular ones have all identical cells. Tissue regions generally recognized as protists include: * […]

Most wastewaters have putrifying (rotting in due course) organic matter. Biological wastewater treatment systems are to covert th organic matter into easily manageable end products, such as carbon dioxide, methane and humus, which can be utilized or dispose off without affecting the environment. The microorganisms use the organic matter as food to provide energy and carbon fo cellular synthesis. Industrial fermentation uses aseptic techniques to […]

sand filter systems used in wastewater: 1. Intermittent Sand Filters The treatment involved in the case of intermittent sand filters applies the sewage, that has already undergone preliminar treatment, onto the filter beds of wastewater sand filter at regular intervals. By this, air can enter the interstices of the bed betwee the dose of sewage to supply the required aerobic bacteria. 2. Construction […]
