Hydrochemistry and dissolved solute load of meltwater in a catchment of a cold-arid trans-Himalayan region of Ladakh over an entire melting period
The hydrochemical study of meltwater draining from a catchment dominated by snowmelt in a cold-arid trans-Himalayan region of Ladakh, India, was carried out for an entire melting season (May–September) during the year of 2010. Cation concentration in the meltwater shows a consistent trend of Ca > >Mg > Na > K for this period. Carbonate weathering has been identified as the ...

Automated Handling of Activated Carbon in Bulk Bags Reduces Dust and Labor for Municipal WTPs
Two cities, one in the United States and the other in Canada, over 700 miles (1100 km) apart, were experiencing nearly identical problems caused by manual addition of powdered activated carbon to their municipal water treatment systems. Both cities not only eliminated a health hazard caused by carbon powder dust, but also reduced the amount of labor required to add powdered activated carbon to ...

Selecting Bulk Handling Equipment
As processors design factories to grow and automate production, it’s easy for them to focus on the islands of production in their systems (i.e. the expensive equipment that actually makes the end product) and overlook the equipment that transfers material between these islands. By this, we don’t mean they forget they need conveyance equipment. Rather, we mean they easily prioritize ...
