Evaluation of industrial dyeing wastewater treatment with coagulants and polyelectrolyte as a coagulant aid.

Wastewater is the major environmental issue of the textile industries besides other minor issues like solid waste, resource wastage and occupational, health and safety. Textile and dyeing mills use many kinds of artificial composite dyes and discharge large amounts of highly colored wastewater. Pretreatment, coloration and after treatment of fibers, usually require large amounts of water and ...

Enhanced Pd pillared clays by Rh inclusion for the catalytic hydrodechlorination of chlorophenols in water

Bimetallic Pd–Rh catalysts supported on pillared clays have been prepared and tested for aqueous-phase hydrodechlorination (HDC) using 4-chlorophenol (4-CP) as target compound. These bimetallic catalysts combine the higher activity of Rh with the better stability of Pd found in previous works with monometallic catalysts. Different combinations of Pd and Rh amounting to 1 wt% total metal load were ...

Temperature dependent morphological evolution of Rh nanopyramids

The temperature dependent oxygen–induced nanopyramidal faceting of atomically rough Rh(210) surface has been studied using scanning tunnelling microscopy (STM). Rh(210) surface is annealed in oxygen at temperature ≥550 K, the surface completely covered with nanometre–scale facets. The annealing temperature is found to be one of the responsible factors for the nucleation and growth of faceted ...

Rainwater harvesting: theorising and modelling issues that influence household adoption

Household adoption of rainwater harvesting (RH) systems recently boomed in Australian urban centres. As a sustainable supplement to the mains supply, water authorities regarded RH as a demand management device. Yet what actually motivated household RH adoption was not well understood. Burawoy's ‘extended case method’ was used to link grounded enquiry with 13 core theoretical concepts drawn from ...

Dynamics of Chromosome Spreading

Consistency of optimum chromosome spreading during harvest of cytogenetic specimens remains a major concern. We have tested the idea that a precise control of the drying rate (the time with which metaphase cells dry), as fixed cell suspension is placed on a slide or an in situ culture in last fixation, may be the answer. Amniocyte and lymphocyte cultures were allowed to dry at defined ...

Rotork’s RHS solves valve access issue at water treatment plant

Recent rehabilitation at the drinking Water Treatment Plant #2 in Olathe, Kansas, USA, has included the installation of Rotork IQ3 intelligent electric valve actuators to replace electric actuators from another manufacturer. In the gravity filter plant, 18 butterfly valves are situated in an area beneath a walkway which made it difficult to access and operate the old actuators. With the new ...

Visibility Trends in Korea during the Past Two Decades

Temporal trends and spatial distributions of visibility measured by the human eye over 60 stations in Korea between 1980 and 2000 are analyzed and discussed. Generally, visibility is lowest on winter mornings and highest on summer afternoons throughout Korea. Visibility in Seoul is now in an increasing trend while it has decreased nationwide, especially in clean coastal areas. Spatial ...

Sequestration of Pb(II) and Ni(II) ions from aqueous solution using microalga Rhizoclonium hookeri: adsorption thermodynamics, kinetics, and equilibrium studies

In the present study, the microalga Rhizoclonium hookeri (RH) was effectively applied to remove the metal ions [Pb(II) and Ni(II)] from aqueous solution in batch adsorption mode experiments. The adsorption process was influenced by several operating parameters such as initial metal ion concentration, contact time, pH, particle size, adsorbent dose, and temperature. The maximum monolayer ...
