A great way to deal with algae, fat, oil and grease (FOG) is to install a Dissolved Air Flotation (DAF). However, many face difficulties in operating the device and therefore, plant fails. This article highlights some insights about DAF, how to select a proper DAF and what to do in order to have a good commissioning….
No one cares about wastewater until it is a problem. Say, the city is charging high surcharges or limiting permit levels that are impacting production or expansion plans. So, what do you do when there is a problem? Start with your goals The first step is to understand what is in the wastewater, how concentrated it is,…
Wastewater generated from food production and agricultural activities is a major source of environmental pollution. It is also among the most difficult and costly waste to manage because food processing wastewater can contain large quantities of nutrients, organic carbon, nitrogenous organics, inorganics, suspended and dissolved solids, and it has high biochemical and chemical oxygen demands….
Wastewater management is an undesirable task for facility managers and their staff. But, it’s an important job, because wastewater problems can quickly turn into a very expensive and unsanitary mess. Below is advice from our engineers about the ten most common wastewater treatment problems you may encounter at your facility and how you can fix them. Problem…
Using coagulants and flocculants to remove suspended solids during industrial wastewater or influent surface water source treatment is common practice. However, failure to properly store or manage these chemicals can lead to downtime, impact production, increased costs, decreased equipment reliability and shortened lifespan, on-site safety issues and more. For instance, poor water quality entering a process…
We classify wastewater treatment as a water use because it is so closely linked to other water uses. Before being released into the environment, much of the water absorbed by houses, industries, and companies should be treated. If you’re unsure what “wastewater treatment” means, think of it as “sewage treatment.” Nature can deal with small amounts…
The generation and emission of odorous compounds such as hydrogen sulfide (H2S), ammonia (NH3) and various volatile organic compounds (VOCs) is a common problem in WWTP. Among these, the case of coastal WWTPs in areas with high population seasonality, such as tourist localities, is especially problematic. The deodorization systems of these WWTPs must be capable…
The IEPP® Pipeline Flocculator is a type of plug-flow reactor coagulation / flocculation system consisting of a long serpentine pipe with a specific length and diameter. The term ” plug-flow ” refers to the constant retention time and mixing energy at any given cross section of the pipe. As such, all particles are subjected to…
Flocculants are used in a wide range of industries to help remove materials suspended in water. In this artical, we examine their role in waste water treatment, detailing what they are, what they are used for, and how they work. We’ll also outline how flocculants differ from coagulants, another common class of waste water treatment…
Coagulation and flocculation are essential components of both drinking water and wastewater treatment. They provide a reliable process for treating water turbidity (the cloudiness or haziness of a fluid typically invisible to the naked eye), which is a key test of water quality. In wastewater treatment, they enable up to 90% reduction in suspended solids…
