  • Treatment Of Produced Water By Electrocoagulation
    Treatment Of Produced Water By Electrocoagulation

    Produced water (PW) is salty water trapped in the reservoir rock and brought up along with oil or gas during production. It subsists under high pressures and temperatures, and usually contains hydrocarbons and metals. Therefore, it must be treated before being discharged to surface water. Different techniques are being used to treat PW through phase separations, system control and design, and chemical treatments. In this paper, we discuss our experimental results on treating PW through electrocoagulation (EC).

Water Reuse Becomes Builders’ Selling Point Water Reuse Becomes Builders’ Selling Point

One way to think about offsetting water rate increases is to reuse the water being consumed. For example, instead of paying $100 a quarter and using the water flowing out of faucets just once, what if you as a homeowner could treat that wastewater on site and reuse it to irrigate the lawn, wash the car, or flush the toilets?

Fuzzy Filter Uses Compression In Advanced Primary Treatment Fuzzy Filter Uses Compression In Advanced Primary Treatment

Advanced primary treatment reduces or eliminates the solids load or organic carbon out of the waste stream. By doing so, a wastewater plant can decrease aeration power and avoid the need to expand its treatment basin size. The removed solids can also be moved to a digester to produce energy.

Benefits Of Walnut Shell Backwashable Media Filters Benefits Of Walnut Shell Backwashable Media Filters

Filtra Systems Company developed the walnut shell filter about 40 years ago. One of the attractions of walnut shell is how well it can handle oil. When oil mixes together with sand, it essentially becomes asphalt. With walnut shell, the oil is coalesced and then, when it’s backwashed, the oil can be released from the shell.

SEPAREL&reg; EF Series SEPAREL® EF Series

The SEPAREL EF series uses external flow which allows water to randomly flow over the hollow fibers and, in turn, contact dissolved gases more frequently. Therefore, desgassing performance with the EF series is higher than the PF series which utilizes internal flow. Also, a lower pressure drop means that larger modules can be used. This video explains how the EF series works.

Small SEPAREL&reg; EF Series Small SEPAREL® EF Series

The small SEPAREL EF series is optimized to remove dissolved gases in water applications with smaller flow rates. The EF series uses external flow which allows water to randomly flow over the hollow fibers and, in turn, contact dissolved gases more frequently. Therefore, desgassing performance with the EF series is higher than the PF series which utilizes internal flow. This video explains how the EF series works.

ABOUT WASTEWATER FILTRATION

Wastewater filtration is often part of the tertiary treatment process that involves the final removal of suspended particles from water that has passed through both the primary and secondary treatment phases and immediately precedes disinfection. As the water passes through the filter, residual suspended material and bacteria is trapped in the filter and are removed from the filtered water. Passage can be blocked by physical obstruction, biological action, adsorption, absorption or a combination of ways. Wastewater filtration is usually the final step in the solids removal process.

With regulations increasing around wastewater effluent, the use of ultrafiltration and microfiltration systems in further polishing effluent has grown. Sand or activated carbon filters can provide a media for bacterial decomposition of nutrients, converting nitrates into nitrogen gas. The rise of water reuse applications is also fueling the increasing use of filters during the final polishing stages of the wastewater treatment process.
