A TRUSTED PARTNER TO WATER & WASTEWATER TREATMENT

Membrane Systems for Municipal Water and Wastewater Treatment

Municipal water supply and wastewater treatment companies worldwide are encountering numerous challenges. The demand for clean drinking water is increasing, while the need to treat wastewater is also on the rise. With diminishing fresh water sources in many areas, it is essential to minimize losses and maximize recycling throughout the entire water management process. Memtik has been developed to address these challenges, which include both quantitative (meeting the increasing demand for potable water and wastewater treatment with limited water sources) and qualitative (treating water with emerging contaminants and adhering to stricter usage and reclamation standards). These challenges are further complicated by the necessity to reduce water losses during processing and enhance water recycling, while also complying with international, national, and local usage and reclamation standards.

Key Applications:

  • Potable water treatment involves the filtration of ground water from various sources, including surface water, lakes, rivers, and seawater. Over time, bore holes used for collecting ground water can become susceptible to contamination from surface water due to cracks developed from ground movement. To address this issue, membrane technology such as the Memtik membrane can be utilized to effectively filter the ground water and remove contaminants, bacteria, and viruses. Additionally, Nanofiltration technology can be employed to eliminate organics, suspended solids, and microbiology from surface water, resulting in aesthetically pleasing and color-free potable water. In coastal areas, seawater desalination using reverse osmosis (RO) membranes is becoming increasingly common, but it requires feed water that is free of suspended solids and microorganisms to prevent fouling of the membranes.

  • Municipal wastewater treatment is essential to ensure that the wastewater meets quality standards before being discharged into the environment. It is important to reduce levels of nutrients such as organics, nitrogen, and phosphate in order to meet regulatory requirements. Additionally, if the treated wastewater will be released into water bodies used for recreational purposes, it must be free of microbiological contamination. Memtik membranes offer a chemical-free solution for removing microbiology in municipal wastewater treatment.

    In cases where space is limited, our membrane bioreactor (MBR) membranes can be used to replace traditional clarifiers, while also reducing the size of the activated sludge bioreactors. The MBR membranes effectively separate sludge from the effluent and ensure complete removal of microbiology.

  • Municipal wastewater treatment is also essential for the reuse and reclamation of water in many communities. Effluent is being utilized for non-potable purposes such as irrigation and industrial use, reducing the demand on potable water sources. This allows for a more efficient use of limited potable water supplies.

    In municipal wastewater treatment, the water must be treated to a high standard, although not necessarily to the level required for potable water treatment. This may involve achieving crystal clear water free of turbidity and low mineral content. The Memtik membrane effectively removes turbidity, ensuring clear water. In cases where a reverse osmosis (RO) process is needed to reduce mineral content, ultrafiltration protects the RO membranes and ensures the long-term trouble-free operation of the RO system.

  • Reclamation & Recycling

    Reused, recycled or reclaimed water is defined as that which has been used more than once before it returns back into the natural water cycle. Water reclamation and reuse have taken on new importance for all kinds of clients, as the cost of raw water rises, discharge violations increase and scarcity concerns become more widespread. In many cases, squeezing every drop out of the water and waste process has gone from superfluous to essential.

    A Variety of Uses

    The use of treated wastewater has grown sharply in the last several years, particularly in arid regions throughout the world. Nearly 50 million cubic meters of municipal wastewater are recycled daily worldwide. Recycling and reuse technologies make water more available, especially during droughts in some parts of the world, while reducing wastewater discharge into the environment. Recycled and treated wastewater has many uses, particularly non-domestic ones such as irrigation, industrial processes and the injection and storage of water into underground aquifers after additional treatment.

    Common Treatment Technologies

    The degree of treatment depends entirely on the desired quality of the recycled wastewater application. Wigen designs and builds a wide array of water treatment processes, providing the best technical solution for each specific need. Solutions include chemical and biological treatment, clarification, filtration, membranes (membrane bioreactors-MBR, ultrafiltration-UF, nanofiltration-NF and reverse osmosis-RO), ultraviolet disinfection, activated carbon and ozone.
