We evaluate the performance of the agents, design the specifications of plants, analyze water quality and sludge, and perform assessments related to the improvement and development of the agents.

Analysis of the properties and condition of the sewage and sludge associated with industrial-effluent treatment, human-waste treatment, treatment of leachate from waste, and treatment of wastewater from incineration facilities.

1.Physicochemical assessments	Coagulation and settlement treatment, dissolved-air flotation treatment, oxidation-reduction treatment, treatment for heavy metal removal, adsorption treatment with activated carbon, and evaluation and selection of the agents used for these treatments.
2.Biological-treatment procedures	Batch-type treatment tests, continuous treatment tests (using model plants), denitrification and dephosphorization treatments, evaluation of the performance of the filters used for immobilized beds and floating carriers, and evaluation and selection of the agents used for these treatments.
3.Treatment assessments	Microscopic observation (evaluation of biota) Microbial test ,treatment of sludge condensation, sludge dewatering treatment, volume reduction of sludge, and evaluation for these treatments.
