Highly concentrated/Less-degradable
We propose methods for processing wastewater/waste fluids difficult to process using existing factory wastewater treatment systems.
Examples of proposals
Treats waste fluids hard to process in-house.
Reliable treatment significantly reduces disposal costs.
We offer systems that maintain high concentrations of microorganisms and propose systems that best suit the needs of each customer.
Sumitomo Heavy Industries Environment offers the know-how needed to identify and acclimatize microorganisms suitable for processing target waste fluids.
Example of system
Examples of solutions
Raw water condition
Characteristics: Mainly propylene glycol (PG)
Countermeasure based on proprietary technologies
H2 inhibition countermeasures
We combine a conventional BIOIMPACT product with a proprietary acid-producing process to prevent H2 inhibition during anaerobic treatment of PG.
Issues in PG treatment
In the acid-producing reaction of high-concentration PG, H2 resulting from the reaction hinders acetic acid reaction. This makes anaerobic treatment difficult.
