Waste water treatment using anaerobic digestion technology

On January 21 in Tay Ninh, Nuoc Trong Tapioca Joint Stock Company in coordination with Rhodia Energy GHG Company (belonging to Rhodia Group - France) has put into use a wastewater treatment plant of a starch processing plant. Biogas Rhodia tapioca water in Tan Hoi commune, Tan Chau district, Tay Ninh.

The factory is built in a 2-hectare campus, using modern anaerobic decomposition technology, which is being applied in many countries around the world.

Biogas Rhodia Water Plant with a investment of US $ 1 million, specializing in biogas production with a capacity of 2 million m3 / year, from biogas recovery from wastewater under clean development mechanism (CDM) and selling credits reduce emissions obtained.

The advantage of the method of treating wastewater produced by biogas and energy anaerobic digestion system is the COD content (chemical oxygen demand) and BOD (biochemical oxygen demand) in waste water will be treated. handling and overcoming 90% of pollution problems.

On the other hand it will create a great economic value of providing biogas as fuel for incinerators to dry powder, replacing other fuels that establishments are using such as cashew nut shell, cashew oil. , FO oil . which pollutes the environment. The use of biogas as fuel will be 25-30% cheaper than other fuels.

The high technical feature of the system is to ensure that biogas plant waste water can contain a COD content of 95% less than when receiving wastewater directly from cassava starch processing plants.

The new biofuel plant will save energy costs , replace fossil fuels with renewable energy sources and improve wastewater treatment; Significant reduction in greenhouse gas emissions and odor treatment.

Rhodia is a chemical group based in Paris (France), and is present all over the world. In 2009, Rhodia's revenue reached 4 billion euros.

The Biogas Plant Rhodia Nuoc Trong is a bioenergy plant, producing the first biogas from the Rhodia Group in Vietnam (led by Rhodia Energy GHG). This is the basis for Rhodia to expand the construction of wastewater treatment plants in Vietnam.
