efficiency depends on the nature of activated carbon used, the water composition, and operating parameters.

The characteristics of the chemical contaminant are also important.The mobile phone industry is an example of clever adaptation.Emphasis is placed on small size, high energy density and low price. The inscription of Ni MH on a battery pack does not automatically guarantee high energy density.Depending on the type and concentration of the contaminant being removed, some carbon filters may require special hazardous waste handling and disposal, which can be costly.(Adapted from LEMLEY et al. The sessions will be interactive and participants will leave the training with hands on ideas and storyboards for interesting/thrilling water stories. Understand important aspects about policies and legal frameworks and how command and control tools (standards and restrictions) can be used in the water and sanitation sector.1995)Carbon filters are relatively easy to install and maintain but skilled labour is required at least occasionally for equipment. After long-term use, their surfaces are saturated with adsorbed pollutants and no further purification occurs. Creating Policies and a Legal Framework (WP) Standards (WP)Restrictions (WP)There is no shortage on innovative solutions to optimise local water management and sanitation systems.Compounds that are less water-soluble are more likely to be adsorbed to a solid.

A second characteristic is the affinity that a given contaminant has with the carbon surface.

Since Ni Cd remains a standard against which other batteries are compared, we evaluate alternative chemistries against this classic battery type.

Nickel Cadmium (Ni Cd) — mature and well understood but relatively low in energy density.

We often get puzzled by announcements of new batteries that are said to offer very high energy densities, deliver 1000 charge/discharge cycle and are paper-thin. Another battery may be built for long life, but the size is big and bulky.

While one battery type may be designed for small size and long runtime, this pack will not last and wear out prematurely.

Activated carbon filters are relatively easy to install but require were used during the 18th and 19th century by the sugar industry for decolourising solutions (CECEN 2011).
