The BKT’s Customizable SBR BCS Introduction and Specifications September 2012 TABLE OF Contents A MESSAGE from BKT I INTRODUCTION What is BCS How BCS Works II TECHNICAL INFORMATION BCS Configuration Equipment & Materials Comparison with Activated Sludge Process III BCS PRODUCT LINE BCS -K for wastewater BCS -H for high strength wastewater IV APPLICATION V REFERENCES A message from 1 BCS is a tried and true technology that BKT was founded on in the mid 1990s. With several dozen installations with custom features and engineering, our clients can rely on successful installations for many years without operational issues thanks to its simplicity and energy efficient design. There are two unique BCS designs, the BCS-H and BCS-K. The BCS-H is for high strength wastewater, such as livestock wastewater, leachate, and industrial wastewater. The BCS-K is for small to medium sized municipal wastewater treatment plants including camp sites, RV parks, and remote regional facilities without distribution pipe networks. The system design and core components are supplied by BKT as a “do-it-yourself” approach, which significantly reduces the project cost by accommodating local resources and parts such as tanks, pipes, etc. BKT in turn will provide key components such as the decanter, blower (either conventional roots blower or energy efficient turbo blower), control system, and other specialty components including custom engineering support. With the large variety of treatment equipment and configurations available for BCS, we believe our clients can benefit from our technology, knowledge, and expertise for wastewater treatment. Thank you • BCS (BCS-K) is similar to conventional SBR in two ways 1) Time-based operation for fluctuating influent characteristics 2) Four basic steps including fill, react, settle, and draw & idle in a single batch reactor • BCS (BCS-H) is different from conventional SBR in three ways 1) Intermittent feed - More stable operation by repetitive cycles between fill & react step before settling 2) Ammonia inhibition prevention - Prevent free ammonia inhibition using bio-ceramic material with ion exchange function 3) Treatment of high strength wastewater - Livestock wastewater, landfill leachate, septage, etc. I INTRODUCTION What is BCS • BKT’s customizable SBR (BCS) is a biological wastewater treatment technology based on a sequencing batch reactor (SBR), and is specialized in organics and nutrient removal. • Two customized product lines are available, the economical kit model (BCS-K) and the high strength model (BCS-H). How BCS Works Basic four steps of SBR operation 2 Why use BCS For economical kit model (BCS-K) • For domestic wastewater • BCS-K is a “Do-it-yourself” package • Cost effective system • Provides engineering, consulting, and equipment package For high strength model (BCS-H) • BCS-H is for high strength WWT • Efficient ammonia inhibition control • Extensive experience & references • Customizable & economical solution BASIC CONFIGURATION II TECHNICAL INFORMATION Configuration of BCS is similar to a typical SBR system. The following contents present the equipment installed for a BCS system and its role and functions. Basic Configuration of BCS Raw Wastewater Effluent BCS Reactor FLOATING DECANTER * • Supernatant discharge w/o major power consumption • Water surface control * Patented 3 MIXER : Mix influent with remaining biomass (MLSS) DIFFUSER : Increase oxygen transfer rate - Nano-bubble diffuser (Optional) BLOWER : Air supply for aeration - Roots blower (Standard) - Turbo blower (Optional) PUMP SYSTEM : For influent feed and sludge wasting Optional configurations CONTROL SYSTEM (-K, -H) • Efficient operation control by pH, DO, and ORP • Real time monitoring • Standard for BCS-H BIO-CERAMIC (-H) • High strength wastewater application. • Prevent free ammonia inhibition. NANO DIFFUSER (-K, -H) • High oxygen transfer rate • Up to 20% energy saving on aeration process TURBO BLOWER (-K, -H) • Energy saving (up to 30%) • Low vibration • No lubricant II TECHNICAL INFORMATION EQUIPMENT & MATERIALS BCS AUTOMATION SYSTEM (Included for BCS-H) • Economic operation & maintenance (blower, mixer, decanter, valves and pumps) by probes and sensors including pH, DO, ORP, Temp. • Easy control and operation by real time monitoring and automated management system FLOATING DECANTER (Patented) • The floating decanter discharges supernatant w/o major power consumption • Effluent suction level control to avoid SS intrusion causing impurity • Easy operation and maintenance BIO-CERAMIC (Only for BCS-H) • High strength wastewater application • Ammonia inhibition prevention by ion exchange function • Semi-permanent lifetime due to ceramic materials. BLOWER (Roots or Turbo Blower) • Air supply to keep oxic condition in aeration tank • Effectively maintain appropriate dissolved oxygen (DO) AIR DIFFUSER • High oxygen transfer efficiency of 80% • Efficient diffusibility and solubility of oxygen because of larger contact surface area and longer air retention time • 20% less hydraulic retention time of aeration tank • Energy saving up to 20% from aeration process Item BKTurbo Roots blower Efficiency (%) 60~70 40~50 Flowrate (?/min) 6.5~188 1.0~400 Flow control (%) 50~100 100 Capacity (HP) 10~200 4~600 Media Material Available Size Specific Gravity Compressive Strength Sphere SiO2, Al2O3 5~20 mm > 1.5 g/cm3 262 kgf/cm2 4 Clients can choose any equipment below based on their needs. COMPARISON WITH CONVENTIONAL TECHNOLOGIES II TECHNICAL INFORMATION Conventional activated sludge and modified ludzack-ettinger (MLE) processes are most common processes for wastewater treatment. Benefits of the BCS system are small footprint and energy efficiency as a result of using single batch reactor system without clarifier and optimum running time of equipment. Applications Conventional Activated Sludge MLE BCS Effluent water quality Moderate Good Good Shock loading prevention Low Low High Energy efficiency Low Low High Foot print Large Large Small Small scale design X X O High strength wastewater X X O Available process comparison table 5 III BCS PRODUCT LINE BCS-K(Kit) for wastewater BCS-K is an economic SBR system designed for low concentration wastewater or sanitary sewer treatment plants.
