Dissolved air flotation - Air flotation machine

KWI Group in Austria is an early manufacturer of dissolved air flotation (DAF) equipment in the world. Currently, it has sold over 7000 sets of equipment in 77 countries, widely used in various water treatment processes such as industrial wastewater treatment, biochemical treatment, process water treatment, and drinking water treatment. KWI Group in Austria is renowned for its dissolved air flotation (DAF) technology and specializes in the design and manufacture of DAF equipment for municipal and industrial water treatment. KWI has over 100 employees, as well as product design and manufacturing centers, providing high-quality quality assurance for the products it designs and sells. KWI, with its years of practical experience, can provide customers with energy-saving, environmentally friendly and reliable solutions. Currently, it has successfully sold over 7000 sets of equipment in 77 countries. In addition, in order to meet the different needs of customers, KWI has also developed a comprehensive series of air flotation products, which are suitable for various water treatments including industrial wastewater treatment, biochemical treatment, process water and drinking water treatment. The basic principle of DAF process in KWI machining and manufacturing center is to use the characteristics of microbubbles to attach to suspended solids in water, lift them up to the water surface, and achieve solid-liquid separation. Generally speaking, dissolved air flotation (DAF) devices consist of two parts: a pressurized dissolved air system that uses a pressure pump and an air compressor to increase system pressure, dissolve gas in water, and form saturated dissolved air water. The air flotation clarification tank utilizes the buoyancy of microbubbles to separate solid suspended solids from water. KWI has developed a series of DAF products with different characteristics, which can be applied to water treatment projects under different conditions to meet various needs. Part of the products are as follows: The DAF process is considered to have stronger wastewater treatment capabilities than traditional processes in many industries, such as oil refineries, chemical plants, natural gas processing plants, paper mills, and food processing plants (containing high proportions of oil, fat, etc.) for wastewater treatment and biochemical sludge concentration. At the same time, air flotation is widely used in drinking water treatment, municipal sewage treatment, and industrial facility process water production. It can be simply divided into the following three categories: industrial fields including food and beverage processing, paper industry, petrochemical industry, textile industry, leather industry, and wastewater treatment for cement, steel, and plastic production and processing. Pre treatment before biochemical treatment, concentration and clarification of biochemical sludge, and advanced treatment of sewage in the municipal field. Surface water clarification, seawater desalination pretreatment, and algae removal processes for drinking water treatment.
