Clean water solutions for low- and middle-income countries don't have to be expensive, but they have to be available. The statistics are sad: 1.7 billion people use a drinking water source contaminated with feces, and more than 500,000 people die of waterborne disease each year, most of them younger than 5 years old. Clean water …

A lot can go wrong in a large urban water system. Pumps malfunction. Valves break. Pipes leak. Even when the system is functioning properly, water can sit in pipes for long periods of time. Water shortages are also a growing problem in a warming world, as communities across the Southwestern U.S. and in many developing nations …
These are small-scale water treatment, reclamation, and recycling plants that are designed to collect, treat, and reuse water in close proximity to both the source …
An illustrated tour of how water treatment systems generally work. Windhoek, Namibia, a city of about 430,000 people surrounded by an arid landscape, has been treating wastewater to achieve a drinking standard and returning it to homes since 1968 for all kinds of uses, including cooking and drinking.Storm water runoff, industrial …

This booklet provides information about the supply of safe drinking-water to small water supplies serving fewer than 5000 people. The intention of optimisation is to achieve the most effective and efficient use of a water treatment plant – which includes getting the best out of each piece of equipment that is
Several water treatment plants in Indonesia have utilized aeration and pre-chlorination before coagulation-flocculation processes to reduce chemical and energy consumption and decrease water treatment costs. This study was conducted to get more understanding on the role of aeration and pre-chlorination in water treatment.

Closing the water cycle by either desalination or wastewater purification promises to provide virtually unlimited volumes of freshwater: in principle, it would enable an increase in water ...
* 1. Equipment can be customized according to customer requirements. System function 1. Low-pressure shutdown protection. When the pre-treatment water supply is insufficient and the high-pressure pump inlet pressure is lower than 0.05MPa, the protection action will be automatically stopped and an audible and visual alarm will be issued.
The costs span a range of small-scale flows, allowing for water reuse treatment costs to be quickly estimated. A robust data set was gathered and synthesized, including: Detailed summaries of treatment technologies, types of reuse, and national reuse regulations, Cost data for over 234 small-scale treatment system,

They performed operational analysis, combined with experimental evaluation using a small-scale helical wound system. The amount of freshwater production in this system was 15,600 l/d [83]. Further to this, they also tested a semi-batch RO-SSD system through process modelling and a small-scale screw pilot with a single-pass RO-SSD …
procedures. In a study of 20 small water treatment plants (WRC Report 738/1/00 Guidelines for the upgrading of small water treatment plants) it was found that most local small water treatment plants experienced problems in operating on a sustainable basis. This was due to a number of both technical and human factors.
Hydropower is a mature energy technology and one that could play a more important role in providing clean and reliable energy. In small-scale contexts, hydropower is useful for providing electricity access, balancing intermittent resources, and as a potential source of energy storage.

Natural water purification relies on the self-purification processes of water, soil and plants. This wastewater purification technique uses no extra artificial energy supply or other necessary substances. Classic natural water purification is divided into purification in macrophyte beds, on the one hand, and helophyte filters on the other hand.
Indonesia's Small-Scale LNG Power Plant Conversion – A Triple Hit for PGN? 2 While ssLNG would increase domestic demand, there is a reason why ssLNG has been on the drawing board for such a long time – justifying its economics is a big challenge.
