Calix, an Australian ,industrial technology, company, is actively scouting targets in Europe for its water and ,wastewater, business area, CEO Phil Hodgson said. The company, with a market cap of AUD 110m (USD 78m), welcomes advisory approaches that could introduce targets, especially as it is more difficult to find targets during the COVID-19 pandemic, given the travel restrictions, the CEO said.

Treatment and reuse of coalmine wastewater in Vietnam ...

Coalmine wastewater has long been a concern due to its potentially severe adverse environmental impacts, such as soil and water pollution. The wastewaters from coalmines, which are commonly referred to as acid mine drainage (AMD), are formed by the chemical and biochemical reactions in the groundwater exposed to the ore and oxygen.

Groundwater pollution, can be caused by untreated waste discharge leading to diseases like skin lesions, bloody diarrhea and dermatitis. This is more common in locations having limited ,wastewater, treatment infrastructure, or where there are systematic failures of the on-site sewage disposal system.

As ocean pH drops, the aquatic environment could become to ,acidic, for kelp to survive. Human use of rivers and estuarine habitats can also affect ,kelp forests,. As we continue to use rivers for such things as logging, dredging, and development, we dislodge large amounts of sediment into the rivers that is ultimately flushed into the oceans.

Because Nitrosomonas europaea contains ammonia-oxidizing enzyme, nitrite reductase, and nitrous oxide reductase, the conversion of ammonia to dinitrogen was tried with different reaction conditions. In aerobic reaction conditions, ammonium was converted to nitrite (NO 2 − ), while under oxygen-limiting or oxygen-free conditions, NO 2 − -N formed from ammonia oxidation by N. europaea was ...

It is speculated, that the aluminum cation is functioning to replace the sodium (or calcium) cation to result in an insoluble aluminum naphthenate precipitate. This method offers an advantage over acidified extraction as a strategy for organic acid removal in that it does not require pH depression.

The results indicated that the initial removal rate of Qu increases from 85.8% to 92.9%. The cleavage pathway of Qu is ,speculated, by Frontier molecular orbital (FMO) theory and verified by GC/ MS analysis. Introduction
