Zero Liquid Discharge (ZLD) describes a treatment process with the goal of removing all the liquid waste from a system. The focus of ZLD is to economically reduce wastewater and produce clean water that is suitable for reuse, thus saving money and being beneficial to...

A sludge or filter press is commonly used to dewater sludge from water or waste water treatment operations. Sludge/filter presses operate applying very high pressures to the cake (from 5 to 15 bars and sometimes even more). Different techniques are used for different types of sludge/filter...

De.mem’s proprietary and in-house developed automated control system “de.live” utilizes Programmable Logic Controller (PLC) and an algorithm optimized for process control, which improves efficiency, performance and reliability of our water treatment systems....

Ion exchange is a water treatment process commonly used for water softening or demineralization, but it also is used to remove other substances from the water in processes such as dealkalization, deionization, and disinfection....

A media filter is a type of filter that uses a bed of sand, peat, shredded tires, foam, crushed glass, geo-textile fabric, anthracite, crushed granite or other material to filter water for drinking, swimming pools, aquaculture, irrigation, stormwater management, oil & gas operations, and other...

Dissolved Air Floatation (DAF) is a water treatment process that clarifies waste water by the removal of suspended matters such as oil & grease or solids. The principle is based on dissolving air in the waste water under pressure and then releasing the air at...

A SALSNES filter system is a new and innovative option for primary treatment of waste water – at a fraction of the footprint, 30-60% lower capital cost and with significantly lower total lifecycle costs when compared to conventional primary treatment....

Forward Osmosis (FO) is an osmotic process that uses a semi-permeable membrane to effect separation of water from dissolved solutes. It works without the application of external, hydraulic pressure. Based on osmotic pressure differences, a draw solute draws water through the membrane until the pressure...

A Membrane Bioreactor (MBR) is the combination of a membrane process, usually based on Ultrafiltration membranes, with a biological wastewater treatment process, the activated sludge process. MBRs are nowadays widely used for municipal and industrial wastewater treatment....
