Dissolved air flotation plays an important role in wastewater treatment process, used to remove impurities from wastewater generated by various industries, including suspended solids, organic matter, and inorganic matter, so that the treated wastewater meets the requirements for reuse or discharge.
Dissolved air flotation is composed of DAF system and main tank body. DAF system includes dissolved air vessel, solenoid valve, safety valve, pressure gauge, air compressor, reflux pump and releaser. Main tank body includes chemical reaction area, contacting area, separation area, sludge discharge tank and clean water area.
What is the flotation process in wastewater treatment？Lamella clarifier is a device used in wastewater treatment to filter and remove sludge. The principle is that under the action of gravity, solid particles are aggregated into larger particles, and solid particles in suspension are removed by prec
IntroductionThe lamella clarifier tank is an improved compact inclined plate sedimentation tank. The lamella clarifier tank adopts IPAL water treatment technology, by adding chemical agents such as PAC, suspended solids, colloids, and organic matter in the wastewater are condensed into larger partic
The pulping and papermaking process requires a large amount of production water. The wastewater generated by bleaching agents, fillers, and their reaction products are all pulping and papermaking wastewater. The primary sources of wastewater are the cooking waste liquid produced during the pulping and cooking process, the mid-stage wastewater produced during the middle stages of the pulping process (washing, screening, bleaching, and beating), and the paper machine white water produced during the papermaking process.
IntroductionWater is widely used in the food and beverage industry, resulting in a large amount of wastewater. The generated wastewater needs to undergo a series of treatments to meet the requirements of reuse or discharge, in order to reduce costs and protect the environment. Pretreatment system is
The lamella clarifier separates sedimentable suspended solids from liquids for the treatment of process wastewater. Compared with the traditional sedimentation tank, the lamella clarifier occupies a smaller area and settles suspended solids faster and easier in a given time.
The sedimentation performance depends on the effective sedimentation area and is independent of the sedimentation depth. Lamella plates are installed inside the tank as a module. The effective sedimentation area of lamella clarifier is the accumulation of the projected area of the lamella plates not the occupied area.
