Nanoen - The sludge generated from industrial wastewater treatment processes may contain high levels of heavy metals such as copper (Cu), chromium (Cr), arsenic (As), nickel (Ni), cadmium (Cd), and other heavy metals. These heavy metals can be harmful to the environment and human health if not properly treated.

  Nanoen - The study of granular sludge was first conducted in the 1980s on Upflow Anaerobic Sludge Blanket (UASB) bioreactors. Granular sludge exhibits higher capability in treating organic and nutrient-rich compounds, particularly phosphorus, compared to conventional activated sludge.

Nanoen  - Businesses and enterprises operating in the business and manufacturing sector that generate wastewater must invest in the construction of wastewater treatment facilities (WTFs) as required by law.

Nanoen - The phenomenon of difficult settling of activated sludge and the return of floating sludge are two common issues in wastewater treatment systems, directly impacting the efficiency of wastewater treatment and resulting in the effluent quality not meeting technical standards.

Nanoen - Recently, Nano Environmental Construction and Technology Company (Nanoen) successfully conducted a training course for the technical staff of Apache Vietnam Shoe Company, aiming to enhance their skills and quality in operating the wastewater treatment system at the company.

Nanoen - In fact, there is no common assessment table for all wastewater treatment works; each treatment work has differences in terrain, treatment technology and wastewater properties. When you want to evaluate any system, you need to survey, record the current status, calculate and evaluate technology, current status and system operation.
