Flootech has delivered a complete wastewater treatment upgrade for Cheng Loong Hou Li Mill in Taiwan. This delivery includes a new pre-clarification with FlooDaf® Microflotation, a biological treatment upgrade and a new tertiary treatment. The biological treatment process has been upgraded by installing new FlooBed® MBBR in front of an existing process. The current activated sludge plant will be upgraded with an efficient fine bubble bottom diffuser system. Due to the extremely demanding wastewater treatment quality standards a tertiary treatment with FlooDaf® Microflotation is also included in the Flootech delivery. Automation system and commissioning services are also included in this complete delivery.
Cheng Loong Hou Li Mill
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.
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.
Correct chemical storage and dosing is essential to the proper operation of industrial and municipal water and wastewater treatment plants. The correct selection of chemicals, chemical dose rate and mixing parameters is critical and has a direct impact on the availability, performance and service life of process equipment.
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.
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.
