wastewater pretreatment Applications

  • Industrial Wastewater Treatment

    Processors are continually facing changing environmental regulations, rising costs for wastewater disposal, increasing utility costs, and a growing demand for green products manufactured using sustainable operations. These factors are driving food and beverage processors to pursue on-site wastewater treatment. ADI Systems’ wastewater treatment technology portfolio and experience can provide treatment solutions from pretreatment through to producing effluent of direct-discharge and/or water-reuse quality. Our vast experience in the food and beverage industry includes custom treatment solutions for dairy (milk, cheese, whey, yogurt, and ice cream), soft drink, fruit and vegetable processing (potatoes, corn, tomatoes), snack food, prepared meals, confectionery, and many others.

  • BOD and COD Removal

    Hydrogen peroxide (H2O2) has been used to reduce the BOD and COD of industrial wastewaters for many years. While the cost of removing BOD / COD through chemical oxidation with hydrogen peroxide is typically greater than that through physical or biological means, there are nonetheless specific situations which justify the use of hydrogen peroxide. These include: Predigestion of wastewaters which contain moderate to high levels of compounds that are toxic, inhibitory, or recalcitrant to biological treatment (e.g., pesticides, plasticizers, resins, coolants, and dyestuffs); Pretreatment of high strength / low flow wastewaters – where biotreatment may not be practical – prior to discharge to a Publicly Owned Treatment Works (POTW);Enhanced separation of entrained organics by flotation and settling processes; and Supply of supplemental Dissolved Oxygen (DO) when biological treatment systems experience temporary overloads or equipment failure. http://www.h2o2.com/industrial/applications.aspx?pid=104&name=BOD-COD-Removal

    Filtration solutions for pre-treatment for desalination industry

    In desalination plants it is of great importance for the operation of the entire plant that the pre-treatment of the water is good before the salt is to be removed. For reverse osmosis (RO) desalination plants a good pre-treatment is essential for avoiding membrane fouling, resulting in reduced water production and increased operational costs.

    Reverse Osmosis Water Testing

    Osmosis is the phenomenon of lower dissolved solids in water passing through a semi-permeable membrane into higher dissolved solids water until a near equilibrium is reached. Reverse Osmosis (RO) is a membrane process of purification which removes most of the the total dissolved solids (TDS) in water by reversing the natural process of osmosis. Pressure is applied to a TDS-concentrated solution against a semi-permeable membrane, causing pure water to diffuse through the membrane. RO has become an important process for a wide variety of applications including: medical, laboratory, desalination, industrial wastewater, Deionized (Dl) pretreatment, and drinking water.

    Water oxidation for private an public drinking water

    Carus permanganates have been used in private and public drinking water applications for more than 40 years. Municipal drinking water plants use CAIROX® and AQUOX® potassium permanganates, and CARUSOL® liquid permanganate in both ground water (well) and surface water for Pretreatment, Pre-oxidation and Organics Removal. Today, municipal water providers face increased challenges as more stringent regulations are enacted and public awareness regarding water quality becomes heightened.

    Chemical Water Treatment for membrane treatments

    Membrane units, in our days are widely used in the water pre-treatment preparation and are becoming one of the most important technologies in the production of high pure water. Nevertheless they often face problems with scaling and fouling and are therefore limited by frequent maintenance, downtime and high costs. Our treatment programs are specifically designed for membrane units like reverse osmosis, ultra- and nanofiltration and enable to remove or preventive control scaling and fouling. Our main target is to run these plants under environmentally friendly and beneficial economic conditions. Special attention is given to an efficient utilization of energy as well as saving precious water. Kurita develops an efficient and effective treatment concept achieving an optimal economic operation and a maximum operational reliability of a plant.

  • Biological wsatewater treatment for dairies

    Dairy raw wastewater is characterized by high concentrations and fluctuations of organic matter and nutrient loads related to the discontinuity in the cheese production cycle and machinery washing. Because the dairy industry is a major water user and wastewater generator, it is a potential candidate for wastewater reuse. Biowater’s wastewater system is based on highly efficient biofilm technology and is ideal for this type of application, one that requires pretreatment prior to discharge to a municipal sewage system.
