Attaquant Enterprises, a leading zero liquid discharge plant (ZID) manufacturers, suppliers and exporters in Chennai, is contributing to a greener environment and keeping environmental sustainability through our new technological zero liquid discharge equipment. These plants are primarily applied in the industrial sector for maintaining and utilizing advanced technological water treatment processes to limit liquid waste.

Our plant uses advanced membrane technologies and vapor compression methods to reduce the amounts of produced water, injected water, and various chemical solvents such as glycol, methanol, and hydrochloric acid (HCL). These technologies improve efficiency and are used in various industrial sectors.

A detailed overview of how our Zero Liquid Discharge Plant (ZID) works:

Being one of the best zero liquid discharge plant (ZID) manufacturers and suppliers in Chennai, our plant uses modern technology for processing waste water and improves performance in industrial areas. Here we have listed down the procedure in detail:

  • Wastewater Pre-Treatment: This is the first step of the ZID system, where materials such as oil, grease, and other particles are separated. During this phase, unwanted substances are removed using techniques like filters, multimedia filters, and ultrafiltration membranes to eliminate suspended solids. We utilize advanced methods, including cutting-edge ultrafiltration membranes and electrocoagulation, which improve flow rates and reduce fouling. Chemicals like aluminum sulfate, ferric chloride, and lime are added to help group smaller particles into larger aggregates for easier removal.
  • Primary Treatment (Clarification): After pre-treatment, we employ clarification methods to remove suspended solids, colloidal matter, and organic contaminants. This process includes biological treatment to eliminate biodegradable materials. We use various techniques, such as sedimentation clarifiers that allow solids to settle by gravity, and dissolved air flotation (DAF), which separates heavy substances like oil and grease by floating them to the surface with fine air bubbles. Our upgraded technology features high-rate clarifiers and membrane bioreactors (MBR) that accelerate sedimentation while reducing the size of clarifier tanks.
  • Concentration (Reverse Osmosis): Reverse osmosis (RO) is an essential method in the ZID process. Pre-treated water is forced through a semi-permeable membrane under high pressure, effectively removing dissolved salts, heavy metals, and other impurities, which helps to reduce the overall volume of water. Our RO membranes are specially designed for high rejection rates and optimal flow performance. Additionally, our plant features energy recovery devices that capture energy from the high-pressure brine reject stream for reuse. We also use low-fouling RO membranes that minimize maintenance needs and extend the lifespan of the membranes, along with a high-efficiency recovery approach that incorporates antiscalants to improve removal efficiency.
  • Brine Concentration (Evaporation/Crystallization): The concentrated brine undergoes evaporation and crystallization, which reduces its volume and concentrates the salt. During this stage, water is boiled off, and dissolved salts crystallize. We utilize mechanical vapor compression (MVC) to recover energy generated during evaporation for reuse, and the crystallization process is facilitated by multi-effect evaporators (MEE). Our advanced heat exchanger materials improve heating efficiency and enhance the durability of the evaporators.
  • Solid Separation and Management: After the brine concentration process, the leftover solids contain salts, metals, and other impurities. These can be reused in various ways, such as for road salt or industrial chemicals, or they can be sent to landfills. Our zero liquid discharge (ZLD) water treatment plants employ centrifuges and belt presses to effectively reduce moisture and remove water from the solids. Additionally, we use advanced recovery technologies to extract valuable salt compounds like sodium sulfate and calcium chloride through selective crystallization methods.
