Journal publication on Integration of zero-valent iron technology into MatiKalp to remove arsenic

S M Sehgal Foundation, India is pleased to share the publication of our recent scientific article titled "A Low-Cost Solution for Arsenic in Water: Integrating ZVI Technology into Ceramic Pot Filter- MatiKalp". It is published in the International Journal of Science and Research (IJSR). 

The study focuses on the integration of ZVI technology into Ceramic Pot Filter which is capable of reducing arsenic, and practically effective, and can be easily implemented in many communities.

We extend our thanks to the Centre for Affordable Water and Sanitation Technology (CAWST), Canada, and Potters for Peace, USA for their technical support in ceramic pot filters. 

The publication is available here: https://www.ijsr.net/archive/v12i5/SR23512152240.pdf

Take the biosand filter survey

CAWST needs your input! In 2023, the biosand filter celebrates a very important milestone - 30 years. We invite all biosand filter implementers and/or trainers to participate in a survey to measure the tremendous impact the technology has had – on the WASH sector, and in people’s lives around the world. The survey includes questions about your experience with implementation, distribution, and impact, and how you have applied new knowledge, skills, and innovations. 
All results will be anonymized, so your answers won’t be attributed to you in our reports. The survey should take between 5 and 10 minutes to complete, and it's currently available in English, Spanish, French and Nepali. Please add a comment if you would prefer to take the survey in another language.

Thanks for your participation!

NEW LIVE WEBINAR: A water professional’s guide to safe storage

Testing and treatment is only part of the equation to achieve safe drinking water at the point of use. How do you select a container for storing water once it’s been through sedimentation, filtration and disinfection? How do you keep it clean and prevent contamination?

To answer these questions and more, the HWTS Network is hosting a live webinar featuring experts from Eawag, the Swiss Federal Institute of Aquatic Science and Technology, and the Centre for Affordable Water and Sanitation Technology (CAWST). Join us to get helpful resources and job aids on safe storage, and stay for a Q&A.
