A new wastewater treatment technology for mixed acid drainagecontaining fluorine

A new environment-friendly wastewater treatment technology was developed for the treatment of mixed acid drainage containing fluorine. The ordinary wastewater system using “slaked lime” is ineffective at removing fluorine; besides, it cannot decompose “hard-type surfactants” in the wastewater, so the amount of generated sludge and the quality of treated wastewater are not at the satisfactory level. This newly developed wastewater system uses microorganisms and calcium carbonate to treat the industrial wastewater that contains strong chemicals such as acids, bases, and hydrogen peroxide. By changing the structure and construction of the treatment tanks, it is possible to treat calcium carbonate and microorganisms at the same time and decompose hard-type surfactants. This greatly contributes to improved water quality, saves resources, and reduces greenhouse gas emissions to one third those of the old system

A new method for treating fluorine wastewater to reduce sludge andrunning costs

Reduction of the sludge generated in fluorine wastewater treatment is a critical problem for the semiconductor industry. We have developed a new method for treating fluorine wastewater in order to reduce sludge and running costs. This method utilizes a small amount of Al(OH)₃ not only as an aggregator for CaF₂ generated from fluoride ions in the wastewater but also as an effective fluorine adsorbent. The Al(OH)₃ as fluorine adsorbent is used repeatedly through an AI(OH)3 reclamation process. This method can effectively treat the concentrated fluorine wastewater to achieve an exceedingly low concentration in one-step treatment. We constructed a practical treatment system using this method by modifying part of an existing conventional system. This new treatment system is able to reduce both the total sludge and running costs to about one-tenth those of a conventional system

An efficient treatment technique for TMAH wastewater by catalyticoxidation

Developers used in photolithography contain toxic tetramethylammoniumhydroxide (TMAH) and this creates a problem of how to properly treat developer wastewater. We have developed a TMAH wastewater treatment technique that consists of a combination of two novel decomposition processes: pyrolyzing TMAH to TMA and decomposing TMA to N ₂, H₂O, and CO₂ by means of a selective oxidation catalyst for nitrogenous compounds. We have tested a system using this technique in long-term treatment of the actual wastewater and have found it to be sufficiently practical. The running cost of a treatment system using our technique would be about one-ninth that of disposing of the wastewater as industrial waste but about 2.3 times that of biological treatment. Compared with biological treatment, however, our system is tolerant to many treatment conditions and operation management is much easier. Furthermore, it occupies only about one-sixth the area of a biological treatment system     

A novel treatment technique for DMSO wastewater

We have developed an efficient treatment technique for wastewater containing dimethyl sulfoxide [DMSO, (CH₃)₂SO], a compound used as a photoresist stripping solvent in semiconductor manufacturing processes. Generally, wastewater containing organic compounds can be treated biologically, but with DMSO wastewater, biological treatment is not available because noxious compounds are produced that harm the environment. Here, we present an effective DMSO wastewater treatment technique in which we add an oxidizing agent and irradiate the wastewater with ultraviolet light to prevent damage to the environment. The use of hydrogen peroxide (H₂O₂) as an oxidizing agent in combination with ultraviolet irradiation causes DMSO to decompose promptly into methanesulfonic acid (MSA, CH₃SO₂OH). With continued treatment, the resultant MSA decomposes gradually into the inorganic compound sulfuric acid (H ₂SO₄). In this reactive route, no noxious compounds are generated. We confirmed that MSA can be biologically treated comparatively easily, and that by combining the initial ultraviolet irradiation/H₂O₂ addition treatment to rapidly produce MSA with a biological treatment to convert the MSA to H ₂SO₄, the total processing can be treated at very low cost. These treatment techniques make use of the characteristically high reactivity of DMSO and are very effective as a means of treating DMSO wastewater
