OdoServe with High-pressure Misting System - Case Study
This manufacturing facility uses potatoes that are cultivated in the selected regions of India to create 200 MT of potato-based starch per day. This factory is situated in the southwest part of the Punjab, India. High TSS effluent has been generated while producing potato starch. High TSS in the influent primarily results in the deposition of sludge and the development of anaerobic zones in the ...

Understanding F:M Ratio
F:M ratio as a theory is one of the most important aspects in wastewater treatment but also one of the most poorly understood concepts. Occasionally textbook numbers are good guides, however there are many instances in which understanding the complexity of F:M ratio may help to provide further insight. As a consultant it is very common to see strong emphasis on calculations such as F:M ratio. ...

BM Respirometry System for essential COD fractionation in wastewater
Wastewater characterization is nowadays considered an indispensable step that provides all the necessary information for a reliable management and design of biological treatment processes. This characterization should mainly include the chemical oxygen demand (COD) fractionation as an indispensable tool for all that. COD fractionation involves identification of non-biodegradable and ...

Why is Water Temperature Important in Determining Water Quality?
Water temperature as a key factor in the success of aquatic environments and influences several parameters that can alter its physical and chemical properties. The temperature of water defines growing seasons and dictates what species can survive in a particular body of water.Temperature plays an essential role in water chemistry and can affect biological characteristics of surface water, ...

Gas Sensors for the Development of Modified Atmospheric Packaging
A huge number of the foods we buy are contained in modified atmospheric packaging (MAP). Fruits, vegetables, meats and baked goods are all contained in a modified atmosphere to extend their shelf life. MAP means food tastes and looks fresher for longer, without any modification of the food itself.Modified atmospheric packaging achieves this by replacing the air that would normally be trapped in ...

Municipal Solid Waste Recycling Methods
Biological or thermal treatment of municipal solid waste can result in recovery of useful products such as compost or energy. Biological Processes Biological treatment involves using micro-organisms to decompose the biodegradable components of waste. Two types of processes are used, namely: Aerobic processes: Windrow composting, aerated static pile composting and in-vessel composting; ...

The Solution of Domestic Sewage Treatment Process
What is domestic sewage treatment? Domestic sewage is mainly various detergents and sewage, garbage, feces, etc. used in urban life, mostly non-toxic inorganic salts. Domestic sewage contains nitrogen, phosphorus, sulfur, and pathogenic bacteria.The features of domestic sewage treatment? Domestic sewage contains a large amount of organic matter, such as cellulose, starch, sugars and fatty ...

Aquaculture sewage treatment process and technical points
The organic matter concentration is high, the suspended solids are many, and the color is deep. The NH3-N concentration is very high due to the large amount of animal feces, and it contains a large number of pathogenic bacteria. The pollutants in the sewage mainly exist in the form of solid and dissolved carbohydrates, which make the sewage show high BOD5, CODcr, SS and chromaticity. , P and ...

Digging Deeper into Soil Tests
In 2022, the technologies available to growers are vast and varied, spanning from biological to digital, all promising to maximize yields. Inputs on the other hand are quite limited, with fertilizer supplies across the globe diminished, leading to high costs for the needed materials. At Sound Agriculture we are developing products and tools that work alongside current technologies and ...

Pilot Plant Study
We have successfully conducted pilot plant studies for various industrial wastewater to study the efficacy of ULRD (UNITED’S LOW RETENTION DIGESTER), The ULRD concept is aimed for treating low & medium strength waste-water at high volumetric loading rates, with shorter hydraulic retention time. ULRDs are simply the vertically stretched versions of traditional UASB digesters. UASB ...

Protecting Against Oxygen Deficiency Risk
What is Oxygen Deficiency? The air we breathe is made up of 78% nitrogen, 21% oxygen, and trace amounts of other gases such as carbon dioxide, neon, and hydrogen. The Occupational Safety and Health Administration (OSHA) defines an environment in which oxygen levels fall below 19.5% as an oxygen-deficient atmosphere, which should be treated as immediately dangerous to health or life. How is ...

How changes in F/M impact microbial populations
Did you know that microbial populations in wastewater are constantly changing? F/M or influent organic makeup and concentrations are a major influence as to what microbes are present. Other factors influencing microbial populations include temperature, pH, D.O., inhibitory compounds, and macronutrients. An underused tool in wastewater treatment is to check your system against the growth curve. A ...

miniDOT Loggers Solve the Case of the Disappearing Jellyfish
Jellyfish Lake in Palau is famous as a place to swim with jellyfish. This is possible because the jellyfish in this particular lake have reduced pneumatocysts, which means they are unable to sting people. Palau is located in the western part of the Pacific Ocean, near the Philippines. Due to its location, Palau is subject to the effects of El Niño, which significantly decreases aquatic ...

Do you Know the Reasons for These Problems in the Aerobic Tank?
The aerobic tank is a structure that maintains the dissolved oxygen content suitable for the growth and reproduction of aerobic microorganisms through aeration and other measures to treat pollutants in the water. The function of the aerobic tank is to allow the activated sludge to perform aerobic respiration, further decompose organic matter into inorganic matter, and remove pollutants. ...
