WWTP with UASB ANAEROBIC DIGESTER for high COD removal & renewable energy
Organic waste (both solid waste and wastewater) from the palm oil industry, tapioca industry, and so on, has the potential to be processed into biogas which is a renewable energy source.
Microorganisms in the Anaerobic Digester break down organic matter in the waste into biogas through a series of stages which include the process of hydrolysis, acidogenesis, acetogenesis, and methanogenesis with the biogas produced consisting of methane CH4, carbon dioxide CO2, and other gases such as H2S and ammonia.
HydromasterAD is an Anaerobic Digester system developed from UASB technology for optimal reduction in COD levels by applying an excellent biomass separation system so that the mixing process of granular biomass, liquid waste, and biogas becomes very effective. Several types of HydromasterAD were developed to suit the characteristics of the waste in each industry ranging from COD of 2,000 mg/L to 80,000 mg/L.
In contrast to the aerobic system with aeration which ends up with a lot of sludge from the activated sludge activities, this system runs without aeration so that this anaerobic system is very low in energy and efficient and instead produces energy with much lower volume of end sludge.
Usually to achieve wastewater quality standards that meet environmental quality standards, an aeration process is still needed after this anaerobic process.
Advantages of HydromasterAD system :
- Decrease in COD levels by 85% to 95%
- Produce biogas as a renewable energy source
- Durable tank with special anti-corrosion coating for > 30 years usage.
- Efficient with high Organic Loading Rate which saves land compared to other systems
