Accurate water-monitoring technologies support short- and long-term sustainability goals in both municipalities and the industrial sector In recent years, São Paulo, Cape Town and other major world cities have come dangerously close to running out of water, and the criticality…
When it comes to water used in boilers, it is important to remove potentially problematic impurities. This offers a potentially huge return on investment, even with the prevention of just one major upset, let alone recurring failures Several decades ago,…
Polyaluminum chloride (PACl) is used as a conditioning agent for reducing the stickiness of waste-activated sludge in wastewater-treatment applications. Presented here is a study comparing two PACl species with different degrees of polymerization The sticky behavior of waste-activated sludge (WAS)…
A few months ago, this column addressed the megadrought in the U.S. Southwest and the increasing concerns over water scarcity [ 1]. Since that time, the drought in that region of the U.S. has continued, further impacting communities across the…
Membrane-supported processes can bring many benefits in water-treatment applications where membranes have not traditionally been used Reverse osmosis (RO) is the standard treatment technology for purifying water supplies for potable water applications and many industrial processes. One of four crossflow,…
To ensure that wastewater discharge meets all compliance requirements, plants should adopt a multi-tiered approach, rather than assuming that the downstream treatment facilities can handle all potential contaminant loads Most industrial manufacturing facilities are required to meet strict limits on…
Currently, enhanced biological phosphorus removal (EBPR) techniques in municipal wastewater-treatment plants (WWTPs) do not work well at temperatures above 25°C, which is common in warm countries. This limitation is expected to extend to more countries with the advent of global…
Understanding the working principles of scrolling and pushing centrifuges can help when deciding which type to use. Feed properties and other factors also play a role When looking for a proven solution for mechanical dewatering, you will most likely come…
Samsung Engineering Co., Ltd.(Seoul, South Korea) has acquired a 24% stake in the Vietnamese water-treatment company DNP (Dong Nai Plastic) Water for about KRW52.7 billion ($41 million). The signing ceremony, was held at the Intercontinental Landmark Hotel in Hanoi, Vietnam,…
Advances in membrane technologies allow processors to delve into gas- and water-separation applications more effectively and efficiently Conventional membranes have a reputation for being “finicky” and “high maintenance” because they don’t operate well under high pressures or temperatures, are subject…
