Rayong Refinery Public Co. Ltd.

flootech rayong refinery public reference

Flootech supplied complete oily wastewater treatment process upgrade to Rayong Refinery Public Co. Ltd. in Thailand.

The wastewater treatment process is a complete delivery including engineering, all the major equipment, piping and instrumentation. The delivery was carried out in close cooperation with the client by closely following the design standards and agreed time schedule.

The biological treatment consists of a two-stage activated sludge system and a secondary clarification unit. The activated sludge basin is designed by  Flootech and aerated by fine bubble bottom aeration membranes. The secondary clarification is a clarifier which has been the choice of hundreds of other industrial customers.

flootech wastewater treatment solution Today, industrial plants are taking full responsibility for the way their process waters affect production and the environment. Fresh water taken from nature is cleaned, utilized and recycled carefully within the processes and, when returned to nature, that water must meet stringent standards. These targets can be achieved using FlooBed-based biological treatment solutions.
flootech biological treatment solution Biological treatment removes dissolved organic hydrocarbons from water. Flootech’s sophisticated, compact Floobed® Moving Bed Biofilm Reactor (MBBR) uses special, freely moving biofilm carriers, which suit high capacity operations, are particularly tolerant of variations in feed flow rate and quality, and give consistently high quality results.
flootech water oil separation solution The first stage of wastewater treatment in petrochemical applications is normally the deployment of API or coalescing plate interceptor (CPI) equipment for the removal of large amounts of oil and suspended solids from the effluent. These units use gravity and density differences between oil droplets, water and suspended solids to separate the different substances from each other. When it has risen, an oil layer is skimmed from the water surface, while bottom layers of sediment are removed by scraper and sludge pump. In CPI units, the separation of oil from water is intensified by the water motion through the plates, which collect oil droplets together as larger ones to separate them from water more easily.
flootech parts and services solution Flootech is proud to supply complete processes and to provide the diverse knowledge and expertise required to ensure that the plant and processes operate reliably. We target at optimized process results and economical operational costs at the customer’s plant. Customer satisfaction is our first priority. A delivery from Flootech ensures close cooperation with the customer starting from the evaluation of the best technological solution to installation, process optimization, training and start-up as well as after sales services covering spare part support and maintenance.

flootech floodaf technology Dissolved Air Flotation (also known as microflotation) is a well-known method of particle separation. Microbubbles are created by dissolving air into water under pressure. When the air-saturated pressurized water is released, microbubbles are formed. Chemical, physical and electrical forces cause suspended solids and colloids to attach to one another and to air bubbles. These particle flocs then float to the water’s surface and are scraped off. Coagulation and / or flocculation chemicals are used to enhance the process.
