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.

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.
