Investigating sustainable solutions for roadside gully pot management
Roadside gully pots are an important component of urban drainage, with over 17 million examples in service throughout England and Wales. Their main purpose is to retain sediments from road runoff, leaves and organic litter in order to avoid blockage or hydraulic restriction of the drainage system. …

One pot synthesis of metal, carbides and polymeric aerogels
<p>"Ultra-low density, three-dimensional assemblies of nanoparticles are referred to as aerogels, and typically are derived from supercritical fluid (SCF) drying of wet-gels. Aerogels are generally fragile materials, but that issue has been addressed successfully by X-aerogels, in which the …

Finite element modeling of flow through ceramic pot filters
… many ceramic filter factories manufacture flowerpot-shaped filters, PHW has transitioned from the flowerpot shape, to a paraboloid shape, and finally to a hemispheric filter shape. The PHW factory conducts flow-rate testing as part of their quality control process and has documented a wide range …

Measuring clay property variation and effects on ceramic pot filter performance
… the country. Originally a distributor of ceramic pot filters (CPFs) manufactured in Accra, PHW began construction of a new factory outside of Tamale in late 2009 when it was recognized that importing filters from Accra was too inefficient to meet the demands for household water treatment and safe …
