One place has already figured out how to profit from poop: A sewage treatment facility in Japan has been mining sludge for gold since 2009, Reuters reported at the time. The Nagano prefecture, northwest of Tokyo, once recorded finding 1,890 grams of gold per ton of ash from incinerated sludge.
P2W offers water treatment solutions for gold mines and acid mine drainage, one system without chemicals for handling cyanides, conductivity and sludge. P2W& 39;...
Instead of collecting a whole city’s wastewater and sending it to a large centralized treatment plant and then piping the reclaimed water great distances for re-use, with sewer mining the acquisition, treatment and re-use of the sewage typically all happens in the same lo ion.
Connecting a remote mine to a central treatment plant via pipeline is expensive, time-consuming, and requires negotiation of complex right-of-way issues, so mining operations typically require decentralized treatment of water and wastewater. Decentralization, in a nutshell, means siting treatment near the water source, demand, or ideally both.
P2W’s motto is – we take care of all wastewater treatment issues so that the client can focus on the mining business. And as our track record shows, P2W’s sustainable wastewater treatment technology provides a sustainable solution for the mining industry, the local community and the environment.
A volume of 2.0 L of mining wastewater intensified with 100 mg CN − dm −3 at initial pH of 12 were introduced into a glass tank and then, recirculated through the electrochemical cell using a peristaltic pump. Samples of 75 mL were collected each time and after settling time of 30 min, the supernatant liquid was filtered through a 0.20 ...
Wastewater treatment expert Paul Cobbin explores three issues mining companies face — plant upgradability, expandability and water scarcity — and how to overcome them.
Sewer mining is one of the many ways the NSW Government is securing our water supply for our growing population. SW8 07/13 What is sewer mining? Sewer mining is the process of tapping into a wastewater system, either before or after the wastewater treatment plant , and extracting wastewater, which is then treated and used as recycled water.
