Wastewater treatment plant STM®

Domestic waste, has been / being placed on communal landfills, contains highly concentrated biodegradable organic materials. Treatment of leachate - arising from its moisture and rainfall – is difficult due to its unstable characteristics, high organic and ammonia content, but is essential to avoid huge environmental risks. Pureco provides turn-key, containerized leachate treatment units, equipped with the latest technological development with the so-called Spacer Tube Module® (STM) operating with Reverse Osmosis technology, installed after suitable pre-treatment steps. Making the technology available in container means transportable, complex, easy to install solution for purifying the dirtiest water of human consumption. Advantages of the STM® The main advantage of these STM® is the large surface area of the membranes, compared to the disc membranes accommodated in the same sized membrane vessels. The larger surface are ensures lower membrane flux (ltr / hr / m2) at identical flow rate, or the possibility pressing higher flow rate through the membrane at constant membrane flux. Due to this phenomena, the RO membrane cleaning becomes less frequent and therefore the cleaned water yield is significantly increased. Main Technological Steps of Pure-RO/LWTC Sand filtration to remove core TSS particles Cartridge Filtration to remove the fine TSS particles STM® designed in one, two or in three-staged configuration depending on the discharge and influent parameters RO membranes allow high organics concentration in the feed flow Possible to operate between 60 – 90 bar pressure within fiberglass housing
