Low-UC anthracite filter media extends the life of your filter before the media must be changed out. Low-UC anthracite typically produces consistent improvements in turbidity removal, due, in part, to more efficient solids loading.

OPUS&reg; Technology - Optimized Pretreatment and Unique Separation Technology OPUS® Technology - Optimized Pretreatment and Unique Separation Technology
OPUS technology combines a proprietary high rate chemical softening process, MULTIFLO, with filtration, ion exchange, and reverse osmosis operated at an elevated pH in single-pass or double-pass mode to generate high effluent water quality suitable for discharge, recycle or reuse.
OPUS® II Technology - a New Innovation for High Recovery of Water for Reuse OPUS® II Technology - a New Innovation for High Recovery of Water for Reuse

OPUS® II is a proprietary process for high recovery of complex wastewater streams. This new innovation uses CeraMem® ceramic membranes as pretreatment for reverse osmosis to reduce the system footprint. OPUS II can be delivered in modular, containerized units to minimize installation costs.

Like the original OPUS technology, OPUS II effectively removes silica, organics, hardness, boron, strontium and particulates. It generates high quality effluent at a high recovery rate, providing clean water for discharge, recycle or reuse.

Selecting The Right Membrane For The Job Selecting The Right Membrane For The Job

In this Water Online Radio exclusive interview, Fred Wiesler, Global Director of Sales for the QUA Group, discusses some of the Company’s key products, including the EnviQ that uses a flat sheet PVDF membrane, and has a .04-micron pore size. It provides ultra-filtration quality water, with the strength of a PVDF flat sheet membrane. Each module has 55 flat sheet membranes connected to a central permeate collection tube, and each module has about ten square meters of area that can produce three to four cubic meters per day of clean water.

Decentralized Membrane Treatment Technology Decentralized Membrane Treatment Technology

In the early 90s, Bio-Microbics introduced membrane treatment technology, traditionally used in drinking water treatment plants, to the decentralized treatment market. In this Water Online Radio interview, Jennifer Cisneros, Director of Marketing for Bio-Microbics and Chair of the National Onsite Wastewater Recycling Association’s Marketing Committee, discusses the use of the onsite technology at an oyster bar where Total Kjeldahl Nitrogen (TKN) was about three times the level of ammonia.

Born out of UCLA and the California Inner Systems Institute, Water Planet is focused on revolutionizing water reuse through next generation membrane technology. As Erik Hoek, CEO of Water Planet, explains in this Water Online Radio interview, the company has two core technologies.

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.

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.
