Why it is Important to Control Algae Growth
A combination of high temperatures, stagnant water and nutrient overload can result in excessive algae growth. These so-called algal blooms can lead to a depletion of oxygen in the water, release of toxins and taste and odor problems. Without treatment, the algae will grow more every year, resulting in an unbalanced ecosystem. Therefore, it is important to control algal blooms for a healthy ...

Combined Experiences of Thermal Hydrolysis and Anaerobic Digestion
Historical Perspective of Thermal Hydrolysis First experiments in US 1976 – Haug et al Thermal pre-treatment prior to anaerobic digestion may result in net energy production from the system because of increased biodegradability and reduced digester heating requirements. Recycling of liquid side streams from thermally pre-treated digested sludge should not significantly increase the oxygen ...

Bi-On Carb OX: Odor treatment in WWTPs. Case study SIMTEJO (Portugal) - Case Study
Avoiding problems associated with foul odors in and around collectors and waste water treatment plants is today one of the major focus points to avoid possible issues related to worker safety, as well as minimizing negative social discomforts caused by the foul odors. The main sources that generate foul odors in WWTPs occur at stages of anaerobiosis, where the lack of oxygen favours the ...

Primary settling tanks covering to prevent odors emission - Case Study
Primary settling tanks covering to prevent odors emission at the Cambrils Waste Water Treatment Plant The Catalan Water Agency (ACA) commissioned a project aiming to minimize odor emission from a Wastewater Treatment Plant (WWTP) located in Cambrils (Tarragona) that suffered from bothersome smells coming from the primary settling tanks. Occasionally, these emissions ended up into neighborhood ...

Three successful approaches for controlling odor in wastewater treatment ponds
Solving odor problems in wastewater treatment ponds should begin with a few investigative questions: How was the pond designed? Has the pond operation changed over the years? What is the purpose and operational theory of each pond, and have ponds been added or closed? Why are odors apparent on some days and not others? Understanding these “hows” and “whys” will ...

Elimination of NH3 and odor from composting by biotrickling filter and preliminary exploration on molecular biology
A biotrickling filter was focused on treatment of odorous NH3 gas, along with volatile organic compounds (VOCs) and other odorous gases during cattle manure composting. The biotrickling filter could treat NH3, the main composition, with removal efficiencies of close to 100% because NH4+ was bio-oxidized in the biofilm to NO3− resulting final NO3− concentrations of about 1000 mg/L. Results of ...

What’s That Smell? Wastewater Edition
Sewage is not known for its pleasant aroma, but what exactly is that smell, and what causes it? The municipal wastewater treatment process can release odors in the collection and treatment process. Wastewater is mostly water, but it also contains organic and inorganic matter, bacteria, and other microorganisms. These all contribute to processes that release gases into the air that are unpleasant ...

Odorous compounds treatment of winery and distillery effluents during natural evaporation in ponds
ABSTRACTDuring treatment of winery and distillery wastewater by natural evaporation in ponds, formation of malodorous compounds induces harmful olfactory effects. In this work, we studied the origin of malodorous compounds and methods to prevent and treat odours. The formation of volatile fatty acids (VFA) from pure substrates (glycerol, lactic and tartaric acids, ethanol) and complex media ...

Integrated Odor Control for Solids Handling Operations
Untitled Document Solids handling operations and solids holding facilities are often major sources of odor at wastewater treatment plants. Hydrogen sulfide and other odorous compounds generated during primary settling and solids holding are released during solids processing. For dewatering processes, belt presses in particular are prone to severe odor problems. Belt press ...
