Silica indices have been calculated for lavas from volcanoes in and around New Zealand. Comparison of geographic distribution of the indices with the ages of the volcanoes indicates there are two different Quaternary volcanic zones within the North Island. One is the Rotorua-Taupo zone with the "volcanic front" lying along White Island, Whale

Silica Sand. Filter sand is an extremely effective filter media because of its ability to hold back precipitates containing impurities. Filter sand size, angularity and hardness are the important filter sand characteristics to ensure proper filtering. Products meet or exceed the NSF/ANSI Standard 61 for Drinking Water System Components, as well
media for intermittent sand filters is a coarse sand with an effective size between 0.3 mm and 0.5 mm. The media sand grains should be relatively uniform in size having a low Uc value (less than 4.0) to promote movement of water and prevent clogging. KEYWORDS: sand/ media specifications, filter media, media grain size
Unimin 100 lb. Silica Sand is renowned for quality, uniformity and consistency. It has a 4060 grade (60% retained on 40 mesh or coarser) and a 2. 0 MILS surface profile when used as an abrasive. Its effective size in filtration is 0. 35 mm. High-quality industrial quartz silica sand can be used for filtration, as an abrasive, as a component of
